Small compostable bags can make collecting food scraps cleaner, but the right choice depends on your bin’s size, how wet your scraps are, and whether your composting program accepts the bag material. These five options range from compact liners for small pails to larger bags with tie handles. Check your bin measurements and local composting rules before choosing: “compostable” does not always mean a bag is accepted in every system.

Our Picks: Best Small Compostable Bags For Food Waste reviews
1. UNNI 2.6-Gallon Bags: A Certified Option for Larger Countertop Pails
UNNI’s 2.6-gallon liners are made for countertop compost pails that need more room than the smallest bins offer. The listing gives a capacity of 2.6 gallons, or about 10 liters, and a bag size of 16.3 by 16.5 inches. At 0.71 mil thick, these are positioned for everyday food scraps rather than unusually heavy or sharp loads.
A notable advantage is the range of certifications listed: BPI to ASTM D6400, CMA, and OK compost HOME. That gives shoppers more information about the bag’s compostability than a general “biodegradable” label alone. Still, the right disposal route depends on the certification and what your local program accepts. UNNI advises storing the bags in a cool, dry place and using them within nine months for best performance.
The 100-count roll may suit households that line a bin regularly and want a larger supply. The trade-off is its size: it may be too roomy for a compact pail, so measure the bin rather than relying on capacity alone.
Pros:
- 100 bags per roll
- 0.71-mil thickness is specified
- Multiple listed compostability certifications, including home compostability
- Bag dimensions are provided for checking fit
Cons:
- May be too large for very small countertop bins
- Best performance depends on proper cool, dry storage and timely use
Verdict: Choose these if your pail is close to the stated 2.6-gallon size and you want a larger roll with clearly listed certifications.
2. GreFusion 1.2-Gallon Bags: A Compact Fit for Small Countertop Bins
GreFusion’s 1.2-gallon bags target small pails and other compact cans. The listing gives dimensions of 15.7 by 15 inches and says they are intended for bins around 0.75 to 1.8 gallons, with a more specific fit guide for round bins up to 10 inches across and 11 inches tall. Those measurements make this one of the more size-specific picks in the group.
The bags are described as corn-starch-based and certified by BPI to ASTM D6400, with OK compost HOME certification also listed. The product description mentions a sealed bottom and a high-density blend intended to help resist leaks and tears. These are useful design details for wet scraps, though no compost liner should be treated as a guarantee against leaks—especially if it sits with liquid waste for a long time.
With 125 bags, this is the largest count in the comparison. It may work well if you have a small bin or want liners for several small cans, but check the measurements carefully: a 1.2-gallon bag may not have enough overhang for a taller or wider pail.
Pros:
- 125 bags per pack
- Detailed size guidance for compact bins
- BPI and OK compost HOME certifications are listed
- Sealed bottom is designed to help contain wet scraps
Cons:
- Small capacity may require more frequent bag changes
- Fit depends on matching both bin width and height to the stated dimensions
Verdict: This is a practical pick for a genuinely small pail when you want a high bag count and published fit guidance.
3. Handle-Tie Food Scrap Bags: Easy to Close and Carry
These 10-liter food-scrap bags stand out for their tie handles. Once a bag is ready to empty, the handles give you a way to close and carry it without searching for a separate tie. That can be convenient when you take scraps from a countertop pail to an outdoor compost area or collection container.
The listing describes the material as plant-based, including corn starch, and says the bags are intended for home and industrial composting. It also describes them as extra thick, tear-resistant, and suitable for wet scraps. Those are product claims rather than a substitute for checking the actual bag’s performance with your own waste mix. The supplied details do not specify a thickness measurement or full bag dimensions, so confirming fit with your bin is especially important.
At 100 bags per pack, this option may appeal to households that value easy closure and carrying. It is less suitable if you need precise size or thickness specifications before buying, since those details are not provided in the product information here.
Pros:
- Handle-tie design can make closing and carrying simpler
- 10-liter capacity is stated in the product title
- Made with plant-based materials, according to the listing
- 100 bags per pack
Cons:
- Exact bag dimensions and thickness are not specified in the supplied details
- Compost acceptance varies by local program and facility
Verdict: Consider these if tie handles matter more to you than detailed sizing information, and confirm the bag dimensions before ordering.
4. AIRNEX 1.6-Gallon Bags: A Thicker-Liner Option for Wet Scraps
AIRNEX offers a 1.6-gallon capacity in a 50-count pack, aimed at countertop bins of that size or smaller. The product description gives a thickness of 0.18 mm and says the bags are made from cornstarch. It also describes them as leak-resistant and tear-resistant, with a load capacity claim of up to 15 pounds. Those specifications make this a promising option to compare if your scraps are often wet or the liner tends to be stressed by heavier loads.
The pack comes in a recyclable box that is designed to work as a dispenser, which may help keep a roll handy near the compost bin. AIRNEX describes the bags as home compostable and says they are intended to break down within six to twelve months. Actual breakdown conditions vary, and your local compost collector may have its own rules, so check before placing the bag in a collection bin.
The main compromise is the lower count compared with the 100- and 125-bag packs. If you change liners often, that may matter more than the extra thickness. Also, make sure the 1.6-gallon size is suitable for your pail before relying on the bag’s stated load capacity.
Pros:
- Stated thickness of 0.18 mm
- Designed for bins up to 1.6 gallons
- Recyclable box also serves as a dispenser
- Home compostability is stated by the manufacturer
Cons:
- 50 bags per pack is a smaller supply than several alternatives
- Local compost programs may not accept compostable liners
Verdict: Pick AIRNEX if you want a thicker small-bag option and prefer a dispenser box, while keeping in mind the smaller pack count.
5. UNNI Easy-Tie Bags: Convenient Handles, but Confirm the Capacity
UNNI’s easy-tie bags use a T-shirt-style design with handles that can be knotted for carrying and to help contain scraps. The product title identifies these as 1.6-gallon, 6-liter bags, while the supplied description gives a conflicting capacity of 2.6 gallons and dimensions of 16.3 by 22 inches. Because those details do not agree, confirm the current product listing and bag measurements before choosing a bin size.
The listing says the bags are made with plant-based materials and have BPI, CMA, and OK compost HOME certifications, including a stated ASTM D6400 standard. These details may help you compare disposal options, but they do not mean every municipal or commercial program will accept the bags. The handles are the main practical distinction from UNNI’s standard 2.6-gallon roll: they make tying and carrying easier, but the capacity discrepancy makes this a less straightforward fit choice.
This 50-count pack could suit someone who values tie handles and can verify the size before ordering. If a precise fit is your priority, the standard UNNI bags have clearer capacity information in the supplied product details.
Pros:
- Handle-tie design helps with closing and carrying
- Multiple compostability certifications are listed
- Plant-based materials are specified
- Suitable for kitchens, dorms, offices, and breakrooms according to the listing
Cons:
- Capacity information conflicts between the title and product description
- 50 bags per pack is a smaller count than the standard UNNI option
Verdict: This may be a good handle-style choice, but only order after verifying the bag’s actual capacity and dimensions on the listing.
How to Choose Small Compostable Bags for Food Waste
Match the bag to your bin’s dimensions
Capacity alone does not tell you whether a liner will fit. Measure the inside width and height of your pail, then check the bag’s listed dimensions. A liner that is too narrow may slip into the bin, while one that is too short may not fold over the rim. GreFusion provides specific bag and bin measurements; other options may require checking the product listing for more detail.
Choose a useful capacity for your routine
A smaller bag can work well if you empty your pail often or have limited counter space. A larger liner may hold more scraps, but it can be awkward in a compact bin. Think about how quickly your household fills a pail and how often you plan to empty it. The 1.2-gallon GreFusion bags suit smaller bins, while the UNNI 2.6-gallon bags are aimed at larger countertop pails.
Consider thickness and the kinds of scraps you collect
Wet coffee grounds, fruit scraps, and food with sharp edges can put more strain on a liner than dry scraps. Compare stated thickness when available: UNNI lists 0.71 mil for its standard bags, and AIRNEX lists 0.18 mm. Thickness is only one factor, though. Bag seams, fit, how long scraps sit inside, and how carefully you lift the liner all affect the chance of a mess.
Check the certification against your composting setup
Industrial composting and home composting are not interchangeable. Look for certifications that match the disposal route you use, and check whether your local service accepts compostable liners. A bag can be certified and still be rejected by a particular collection program. If you compost at home, confirm that the product is suitable for home composting and follow the instructions for your system.
Decide whether handles are worth it
Tie handles can make a bag easier to close and carry, especially when you take food scraps outside. They may also help contain odors while the bag is being moved. Standard liners can be a simpler choice if you empty them directly into a compost bin and want a larger roll or a more clearly specified size.
Think about storage and pack count
Pack size affects how often you need to reorder, but compostable bags can be sensitive to storage conditions. UNNI advises keeping its bags in a cool, dry place and using them within nine months for best performance. If you buy a larger supply, store it away from heat and moisture and consider how quickly you will use the bags.
Frequently Asked Questions
Can compostable bags go in any compost bin?
No. Some composting programs accept certified compostable liners, while others accept food scraps only. Check the rules for your local service or home composting setup before putting a bag in the collection bin.
Are compostable bags the same as biodegradable bags?
Not necessarily. “Biodegradable” can be a broad claim, while compostability certifications refer to particular standards and conditions. Look for the specific certification and confirm that it matches how you plan to dispose of the bag.
How do I know what size liner my countertop pail needs?
Measure the bin’s height and width, including enough extra material to fold over the rim. Compare those measurements with the bag dimensions, not just the stated gallon capacity. A little extra room can make a liner easier to fit and remove.
Can I leave food scraps in a compostable bag overnight?
That depends on the bag, the scraps, and the conditions in your kitchen. Wet waste can place more strain on a liner over time, so empty the pail as needed and avoid letting liquid collect in the bottom.
What is the advantage of tie-handle compost bags?
Handles make it easier to close a bag and carry it to an outdoor compost bin or collection point. They can be especially useful if you move the bag while it contains scraps, though you should still check that the bag fits your pail.
How should I store compostable bags?
Follow the product’s storage instructions. For the UNNI bags described here, the manufacturer recommends a cool, dry place and use within nine months for best performance. Avoid storing liners where they may be exposed to moisture or excess heat.
Final Recommendation
For a larger countertop pail, the UNNI 2.6-gallon bags offer a useful combination of a 100-count roll, stated thickness, and several listed compostability certifications. For a smaller bin, GreFusion provides detailed fit guidance and the highest bag count in this group. Choose AIRNEX if thickness is a priority, or a handle-tie option if easy carrying matters more. Before buying, verify the bag dimensions and check that your composting program accepts the liner material.
