A strong compost-bin bag fits the pail, holds everyday food scraps, and offers compostability certifications suited to where you dispose of it; countertop-bin owners have the most options here. This roundup compares ten liners ranging from 1.3 to 13 gallons, including flat-top bags, tie-handle styles, and a larger drawstring format. Capacity and dimensions matter because a bag that is too small may slip into the bin, while an oversized liner can bunch around the rim.
Certifications also differ: some products list home-compost certifications, commercial certifications, or both, so check what your local composting route accepts. We rank the closest countertop fits first, then consider thickness, pack size, closure convenience, and stated certifications to help match a liner to your bin and routine.
UNNI 2.6 Gallon Bags lead as the best all-around fit for a common small kitchen compost bin: the 2.6-gallon capacity, 16.3-by-16.5-inch size, and 0.71-mil thickness suit everyday food scraps. Its 100-count roll provides a substantial supply, and the listed BPI, CMA, and OK compost HOME certifications give buyers useful disposal-route information. Measure your pail before ordering, since capacity alone does not guarantee a close fit; check local facility rules before placing certified bags in a compost stream.

Best for: Compact-bin everyday liner.
Why it ranks #1: A practical countertop fit with 2.6-gallon capacity, 0.71-mil thickness, 100 bags per roll, and listed BPI, CMA, and OK compost HOME certifications.
The 0.71-mil thickness is the key distinction for this 2.6-gallon UNNI liner, giving a compact kitchen bin a sturdier-feeling bag for daily scraps and peels. Its 16.3-by-16.5-inch dimensions target small compost pails, while BPI, CMA, and OK compost HOME certifications offer multiple composting credentials.
A 2.6-gallon capacity and 16.3-by-16.5-inch dimensions make this a fit candidate for compact countertop bins; measuring the bin first helps avoid a loose or short liner. The open, flat top has no handles or drawstring, so it lines the rim simply and comes out without a closure step.

Backyard compost compatibility is a notable distinction of BioBag’s 2.6-gallon food-scrap liners, which are described as home compostable and suitable for a backyard compost system. The 16-by-17-inch bags are intended to line kitchen pails, helping keep the bucket clean while collecting everyday food scraps.
A 2.6-gallon capacity and 16-by-17-inch dimensions make these a candidate for kitchen compost pails; checking your pail dimensions helps assess the fit.

BioBag also identifies them as home compostable and compatible with backyard compost systems, while CMA composter approval offers another relevant composting credential for food-waste routines.

3. UNNI Handle-Tie Bags
- Capacity: 2.6 gallons
- Dimensions: 4.61 x 3.54 x 3.43 in
- Material Feature: Biodegradable
- Form: Bag
Best for: Tie-handle 2.6-gallon liner.
Why it ranks #3: The 2.6-gallon bags fit many countertop bins, add tie handles for closure and carrying, and list BPI, CMA, and OK compost HOME certifications.
UNNI’s tie handles distinguish this 2.6-gallon liner, making it easier to close and carry food scraps from a small kitchen bin. The 16.3-by-22-inch bag is listed at 0.68 mil, and its BPI, CMA, and OK compost HOME certifications cover multiple composting settings.
With a 2.6-gallon capacity and 16.3-by-22-inch dimensions, this liner targets countertop pails; checking your bin’s width and height helps assess coverage. T-shirt-style handles can be tied for carrying and help contain odors and mess during removal. The 0.68-mil material is specified alongside certifications from BPI, CMA, and OK compost HOME, supporting buyers who want both a closable bag and documented compostability credentials for their chosen disposal route.
- 2.6-gallon capacity for small kitchen bins
- Tie handles for closure and carrying
- BPI, CMA, and OK compost HOME certified
- 16.3-by-22-inch dimensions provided
- The 50-count roll contains fewer bags than UNNI’s 100-count flat-top option.

This UNNI option suits countertop-bin users who want tie handles and a 2.6-gallon capacity, with certifications spanning commercial and home composting. Compare the 16.3-by-22-inch dimensions with your bin before using it.

#4 · Thickest Small Bags
4. AIRNEX 1.6 Gallon Bags
- Capacity: 1.6 gallons
- Dimensions: 2.5 x 3.74 x 13.78 in
- Material Feature: Compostable, Heavy Duty, Plant Based
- Form: Bag
Best for: Wet-scrap resistant small bags.
Why it ranks #4: Sized for bins up to 1.6 gallons, these cornstarch bags specify 0.18 mm material and claim leak and tear resistance for wet or sharp scraps.
AIRNEX specifies 0.18-millimeter bags and emphasizes leakproof, tear-resistant handling, making this 1.6-gallon option suited to wet scraps and sharp food waste. Its recyclable box doubles as a dispenser, so bags can stay accessible beside a compatible countertop bin during regular kitchen collection.
The stated fit is for countertop bins of 1.6 gallons or less, giving buyers a clear capacity boundary when choosing a liner. AIRNEX says the 0.18-millimeter cornstarch bags remain elastic under heavy loads and resist leaks from wet waste and tears from sharp scraps, reducing the need to double-bag according to the listing. A 50-count supply comes in a recyclable box that doubles as a dispenser, supporting convenient access near the bin.
- 0.18-millimeter material
- Listed as leakproof and tear-resistant
- Compatible with bins of 1.6 gallons or less
- Recyclable box doubles as a dispenser
- The stated compatibility stops at 1.6 gallons, excluding larger countertop bins.
Skip it if you have a bin larger than 1.6 gallons; BioBag’s 2.6 Gallon Food Scrap Bags are sized for a larger pail.
AIRNEX is a practical match for a countertop bin no larger than 1.6 gallons, especially when wet or sharp scraps are part of the routine. Its specified capacity boundary rules out larger pails.

#5 · Large Tie-Handle Pack
5. YORJA Tie-Handle Bags
- Capacity: 1.6 gallons
- Dimensions: 8.46 x 1.18 x 9.84 in
- Material Feature: Compostable, Heavy Duty, Odor Resistant…
- Form: Compostable Tie Handles Food Scrap Bags
Best for: Tie-handle countertop carry.
Why it ranks #5: A 120-count option for 1.6-gallon bins, with a 28.3-inch opening circumference, tie handles, and EN 13432 and OK compost HOME certifications.
The 4.7-inch tie handles make YORJA’s 1.6-gallon liners easy to gather and carry from a countertop bin, helping contain food scraps during removal. A 28.3-inch opening circumference and 13.8-inch length specify the fit, while the cornstarch-and-PBAT bags are certified to EN 13432 and OK compost HOME.
For a 1.6-gallon pail, the stated opening circumference and bag length help assess coverage before use. The tie handles provide a direct way to close the liner and lift it out, reducing the chance of a messy transfer. Its 0.71-mil material is specified for everyday kitchen use, and the product description identifies the bags as tear-resistant and leak-proof for wet scraps. The manufacturer recommends using bags within 18 months of opening for optimum strength.
- 1.6-gallon capacity with stated opening and length
- 4.7-inch tie handles for closure and carrying
- EN 13432 and OK compost HOME certified
- Cornstarch and PBAT material
- For optimum strength, bags are recommended for use within 18 months of opening.
Skip it if you need a flat-top liner without handles; BioBag’s 2.6 Gallon Food Scrap Bags are an alternative for a larger pail.
YORJA suits countertop-bin users who want tie handles for carrying wet food scraps and have a 1.6-gallon pail. Check its opening measurements against your bin, and plan to use opened bags within the stated 18-month window.

6. Generation Earth Bags
- Capacity: 6 liters
- Dimensions: 23.23 x 8.46 x 0.39 in
- Material Feature: Biodegradable, Compostable, Plant Based…
- Form: Bag
Best for: Tie-handle commercial composting.
Why it ranks #6: The 1.6-gallon size and 120-count pack suit frequent countertop use; tie handles simplify carrying, and the listing states BPI certification and ASTM D6400 compliance.
Tie handles are the useful feature of Generation earth’s 1.6-gallon bags, providing a way to seal and carry food waste from a countertop bin. The 120-count supply supports ongoing collection, and BPI certification with ASTM D6400 compliance identifies the bags for commercial composting environments.
A 6-liter capacity targets small kitchen compost bins, while the listed tie handles let users close the opening before carrying food scraps away. That closure can help prevent spills during transfer from the counter to a compost collection point. The plant-based material is listed as corn starch, PLA, and PBAT, and BPI certification to ASTM D6400 supports use in commercial composting environments. With 120 bags, the package provides a larger supply than a 50-count roll.
- 6-liter capacity for small countertop bins
- Tie handles for sealing and carrying
- BPI certified and meets ASTM D6400
- 120 bags per package
- The listed composting certification is for commercial environments, not a stated home-compost certification.
Skip it if you specifically need stated home-compost certification; YORJA’s 1.6 Gallon Tie-Handle Liners list OK compost HOME certification.
Generation earth suits users with a 6-liter countertop bin who want tie handles and a larger 120-bag supply for commercial composting. Its listed certification is commercial-focused, so account for your intended composting route.

7. SUPERBIO 1.6 Gallon Bags
- Capacity: 1.6 gallons
- Dimensions: 5 x 3 x 3 in
- Material Feature: Compostable
- Form: Bag
Best for: Small bin with tie closure.
Why it ranks #7: These 1.6-gallon liners use a handle-tie format and list BPI, OK compost HOME, and Seedling certifications; the pack contains 50 bags.
The handle-tie opening is the practical feature of SUPERBIO’s 1.6-gallon bags, allowing scraps to be closed up before carrying the liner away. Each 16.1-by-19.3-inch, 0.63-mil bag is sized for a countertop food-scrap bin, and the package includes 50 bags on a roll.
The 1.6-gallon capacity targets smaller countertop bins, while the listed 16.1-by-19.3-inch dimensions give a reference for checking the liner against your pail. Handle ties let you close the opening before lifting, a useful step when taking food scraps to a collection point. BPI commercial compostability and OK compost HOME certification are both listed, but the package does not include a compost bin, so this is a liner-only purchase.
- 1.6-gallon capacity for countertop bins
- Handle ties for closing and carrying
- BPI and OK compost HOME certifications listed
- 50 bags per roll
- The package does not include a compost bin.
Skip it if you need a liner for a bin larger than 1.6 gallons; BioBag’s 2.6 Gallon Food Scrap Bags suit a larger-capacity pail.
This is a fit for households with a 1.6-gallon countertop bin that want tie closure and listed home-compost certification. Check the bag dimensions against your bin, and remember the package supplies bags rather than a container.

8. ANECO 2.6 Gallon Bags
- Capacity: 2.6 gallons
- Dimensions: 16.5 x 16.3 in
- Material Feature: Compostable
- Form: Bag
Best for: Flat-top 2.6-gallon bags.
Why it ranks #8: The 2.6-gallon flat-top design fits over a bin rim, and its roll has pre-cut tear lines; the supplied details do not list certifications or thickness.
The roll-and-box dispensing setup distinguishes ANECO’s 2.6-gallon compostable bags: a wide-opening box lets you pull a bag out or return the roll directly. Pre-cut tear lines help separate bags, while the flat-top opening fits over a bin rim without adjusting or stretching handles.
At 16.5 by 16.3 inches and 2.6 gallons, these flat-top bags target compact kitchen waste bins. The open top can be placed over the rim without manipulating handles, which simplifies lining the pail before collecting food scraps. A roll keeps the bags organized, and pre-cut lines make dispensing one at a time straightforward. The wide-opening box also makes it easier to access the roll; the listed material is cornstarch and the bag is compostable.
- 2.6-gallon capacity for small kitchen bins
- Flat top fits over a rim without handle adjustment
- Pre-cut tear lines for separating bags
- Wide-opening box provides access to the roll
- Flat-top bags have no tie handles for closing before carrying.
Skip it if you want a tied closure for carrying scraps; YORJA’s 1.6 Gallon Tie-Handle Liners provide handles to gather and tie.
Pick ANECO for a 2.6-gallon pail when tidy roll storage and simple flat-top placement matter more than a tied closure. Its dimensions are a useful starting point, but compare them with your bin before choosing.

9. INNOTAK 1.3 Gallon Bags
- Capacity: 5 liters
- Dimensions: 2.3 x 3.1 x 2.3 in
- Material Feature: Compostable
- Form: Bag
Best for: Small pails, thicker liner.
Why it ranks #9: A compact 1.3-gallon option for smaller pails, with stated 0.87-mil thickness and 50 bags; the listing does not provide specific certifications.
The 0.87-mil material is the defining specification of INNOTAK’s small compost bags, paired with a compact 1.3-gallon capacity for countertop pails. The listing says they fit bins from 1.3 to 1.6 gallons and suit scraps, coffee grounds, and fruit peels, giving smaller kitchens a focused liner size.
The stated 1.3-gallon capacity and compatibility with 1.3-to-1.6-gallon pails help target the liner to a compact countertop bin. Cornstarch construction is identified as plant-based and compostable, and the listed 0.87-mil thickness is intended for stronger everyday handling. The 50-count package supports routine food-scrap collection without requiring a large storage space, while its small-bag format keeps the choice centered on kitchen pails rather than full-size household waste bins.
- 0.87-mil material
- Fits listed 1.3-to-1.6-gallon pails
- Cornstarch material
- 50 bags per package
- The 1.3-gallon capacity is too small for bins larger than the stated 1.6-gallon fit range.
Skip it if you use a bin larger than 1.6 gallons; BioBag’s 2.6 Gallon Food Scrap Bags offer a larger stated capacity.
Choose INNOTAK for a compact countertop pail in the stated 1.3-to-1.6-gallon range, especially when the listed thicker material matters to your routine. Its small capacity makes it unsuitable for larger kitchen bins.

10. Simply Bio 13 Gallon Bags
- Capacity: 13 gallons
- Dimensions: 9 x 3.25 x 3.25 in
- Material Feature: Compostable, Disposable, Heavy Duty, Plant Based
- Form: Bag
Best for: Large kitchen-scrap loads.
Why it ranks #10: The 13-gallon capacity and 23.7-by-29.4-inch dimensions suit a large waste container, not the small countertop compost bins most shoppers mean.
A 13-gallon capacity sets Simply Bio apart from countertop-pail liners, giving users a larger bag for kitchen scraps and other household waste. The 1-mil thickness is paired with a drawstring for closure, while the 23.7-by-29.4-inch dimensions indicate a tall-kitchen format rather than a small caddy liner.
The 13-gallon size and 23.7-by-29.4-inch dimensions suit a larger kitchen waste container, so this format may better serve households collecting more scraps before disposal. A drawstring provides a way to close and lift the bag, while the listed 1-mil thickness is intended to resist punctures and leaks in everyday use. The plant-based PLA and PBAT material is listed as compostable, with ASTM D6400, US BPI, and OK Compost Home certifications.
- 13-gallon capacity for larger waste loads
- 1-mil thickness
- Drawstring closure
- ASTM D6400, US BPI, and OK Compost Home certifications listed
- The 13-gallon capacity is oversized for a typical small countertop compost pail.
Skip it if you need a liner for a small countertop pail; YORJA’s 1.6 Gallon Tie-Handle Liners fit that smaller-bin use case.
Simply Bio is for users collecting larger kitchen-scrap loads in a tall, 13-gallon container who want a drawstring closure. Its dimensions and capacity make it a poor match for compact countertop compost bins.

Why Compostable Liners Can Fail Before Disposal
Moisture and time are the main practical risks to manage with compost-bin liners. Food scraps can be wet, and several products emphasize leak resistance or strength, including the 0.18 mm AIRNEX bags and the 0.71-mil YORJA bags. Those details are useful, but they do not establish that any liner will hold liquid indefinitely.
Empty the pail regularly, especially when it contains wet scraps, and avoid treating a compostable liner like a long-term storage bag. YORJA specifically recommends using its bags within 18 months of opening for optimum strength.
Storage also matters: SUPERBIO advises keeping its product away from heat. A liner that weakens may split during lifting, so tie handles can help contain scraps during a short carry, but they do not replace checking the bag and emptying it before it becomes overloaded. Match the liner to normal kitchen use rather than relying on it to contain standing liquid.
Check the Bin Rim, Not Just the Gallon Label
A matching gallon capacity does not guarantee that a liner will fit your compost bin securely. Capacity is only one measure; opening width, bag length, and closure style affect how the liner sits over the rim and how easily you can remove it. For example, YORJA lists a 28.3-inch opening circumference and 13.8-inch bag length for its 1.6-gallon bags, while SUPERBIO lists a 16.1-by-19.3-inch size for the same capacity.
UNNI’s flat-top 2.6-gallon bag measures 16.3 by 16.5 inches, whereas its handle-tie version is 16.3 by 22 inches. That difference can matter if your bin is tall or if you want material to fold over the edge.
Measure your bin’s width and height, compare them with the bag dimensions, and consider whether handles or a flat open top suit the rim. Confirm the manufacturer’s sizing guidance when the listed measurements are unclear.
How to Choose Compost-Bin Bags
Capacity and Fit
Look for a bag capacity and dimensions that suit the bin, rather than choosing by gallon label alone. The countertop-oriented options span 1.3 gallons for INNOTAK, 1.6 gallons for several models, and 2.6 gallons for UNNI, BioBag, and ANECO; Simply Bio is much larger at 13 gallons. Dimensions vary even among bags with the same capacity: YORJA lists a 28.3-inch opening circumference and 13.8-inch length, while SUPERBIO lists 16.1 by 19.3 inches.
Smaller pails may favor the 1.3-gallon option; bins around 1.6 gallons have several choices, while common 2.6-gallon countertop bins suit the larger small-bin liners. Measure the rim and height before selecting a size.
Thickness and Everyday Strength
Check the stated thickness when you regularly collect wet scraps or want extra margin against tearing. The listed figures range from 0.63 mil for SUPERBIO to 0.71 mil for UNNI’s flat-top bag and YORJA, 0.87 mil for INNOTAK, and 1 mil for Simply Bio; AIRNEX specifies 0.18 mm. Thickness alone does not prove leak performance, but it is a useful comparison alongside the stated use and material.
For a small bin with typical peels and coffee grounds, a standard countertop liner may be sufficient. Buyers handling heavier or wetter loads may prefer a product with a higher stated thickness or explicit leak-resistance language, such as AIRNEX, while remembering to empty the liner regularly.
Closure and Composting Route
Choose a closure and certification that fit how you carry scraps and where they will be processed. Flat-top UNNI and ANECO bags line the bin without handles, while tie-handle versions from UNNI, YORJA, Generation Earth, and SUPERBIO can be closed for carrying. Certification claims differ: UNNI lists BPI, CMA, and OK compost HOME; BioBag describes home compostability and CMA approval; several 1.6-gallon options state BPI or home-compost certifications.
A buyer who carries a filled bag to a collection point may favor handles, while someone who lifts the whole liner from a pail may prefer a flat-top fit. Check the accepted materials with your local compost program; a product certification does not establish that every facility accepts it.
Which Compost-Bin Bag Should You Choose?
For a typical 2.6-gallon countertop pail, choose UNNI 2.6 Gallon Bags: its 100-count pack, 0.71-mil thickness, and multiple listed certifications make it the strongest all-around match. If you want handles on a similar-size liner, UNNI Handle-Tie Bags offer a 2.6-gallon fit and certified closure convenience. For a 1.6-gallon bin, AIRNEX 1.6 Gallon Bags stand out for specified 0.18 mm thickness, while YORJA Tie-Handle Bags provide 120 liners and stated home-compost certification.
Choose BioBag Food Scrap Bags if home compostability and CMA approval are priorities in a 2.6-gallon size. Smaller pails may suit INNOTAK 1.3 Gallon Bags.
Skip Simply Bio 13 Gallon Bags for a countertop caddy; their capacity is aimed at larger containers.

Frequently Asked Questions
Can certified compostable bags go in every municipal food-scrap collection program?
No. Municipal programs set their own rules, and certification alone does not guarantee acceptance. Check your local collection guidelines for approved bag types and certifications before putting a liner in the food-scrap stream.
If the program does not accept compostable bags, follow its instructions for emptying the scraps and disposing of the liner.
How often should I empty a countertop compost bin to prevent a liner from weakening?
Empty it before scraps become wet, heavy, or difficult to lift, rather than relying on a fixed schedule. Moisture and the weight of food waste can stress a liner, so check it regularly and avoid leaving liquids in the bin. If the bag feels weakened, remove it carefully and replace it.
Should I line a compost bin with a bag if I plan to home-compost the scraps?
Use a liner only if it is labeled for home composting and your composting setup accepts it. The listed products vary in their certifications, so check the package for the specific home-compost designation rather than assuming all compostable bags qualify. When uncertain, put scraps in the bin without a liner.
How can I choose the right bag size for my countertop pail?
Measure the pail and compare its dimensions with the bag details, instead of choosing by gallon capacity alone. A bag may hold the stated volume yet fit poorly around the rim or base. The UNNI 2.6-gallon option lists dimensions of 16.3 by 16.5 inches; check your pail before ordering.
Are tie-handle liners useful for carrying food scraps to a collection point?
Tie handles can make it easier to close and carry a liner, but check that the bag size suits your bin and that its certification matches your disposal route. The listed 1.6-gallon and 2.6-gallon options include tie-handle styles. Confirm local collection rules before placing a closed bag in a compost stream.
Final Words
For a typical 2.6-gallon countertop pail, UNNI 2.6 Gallon Bags are the strongest all-around match, with listed dimensions, 0.71-mil thickness, and BPI, CMA, and OK compost HOME certifications. Measure your pail and confirm local acceptance first. Choose a tie-handle option for a closure, AIRNEX for a 1.6-gallon bag with specified thickness, or INNOTAK for a smaller pail; skip the 13-gallon option for a countertop caddy.
