A compost bag that tears open in your bin is not a helper — it is a mess you clean off the floor. The right liner holds wet coffee grounds and banana peels without splitting, closes off easily, and actually breaks down as promised. That is the difference between hating your routine and keeping it simple.

How To Choose The Best Bags For Compost
Picking the right compost bag starts with matching your bin size, deciding how much strength you need, and checking which compost certifications your local facility accepts. Here are the three factors that matter most.
Size and Capacity
Bag sizes range from small 2.6-gallon liners for countertop bins up to 13-gallon bags for standard kitchen trash cans. A 2.6-gallon bag fits compact 10-liter bins while a 13-gallon bag handles full-size cans. Buying the wrong size means you either waste space or have a bag that does not fit the rim.
Thickness (Mil) and Durability
Thickness is measured in mils (one-thousandth of an inch). A 0.71 mil bag is the minimum for daily food scraps, but bags around 0.87 mil or with a thickened design handle wetter, heavier loads without tearing. Thicker bags resist punctures from sharp items like eggshells or coffee pods.
Certifications
BPI certification confirms the bag meets ASTM D6400 standards for industrial composting facilities. OK Compost HOME certification (by TÜV AUSTRIA) means the bag breaks down in a backyard compost pile. If your local composting program requires one or the other, the certification on the label determines whether your bag is accepted.

In‑Depth Reviews
1. ECOLipak 13 Gallon Compostable Trash Garbage Bags
A thick 0.87 mil bag that holds up under a full week of kitchen scraps without springing a leak.
At 13 gallons and 0.87 mil thick, this bag is noticeably tougher than the average 0.71 mil liner you find in smaller packs — so drenched coffee grounds and leftover pasta sauce stay inside where they belong. The 24-inch by 32.28-inch dimensions fit standard tall kitchen cans, and the 50-count roll covers about a month of daily use for a typical household. Buyers report the bags are “sturdy, durable, no tearing or leaking for everyday kitchen use,” which lines up with the thickened design that resists punctures.
Unlike the 2.6-gallon liners, this 13-gallon bag holds 13 gallons versus the UNNI option’s 2.6 gallons — so you swap bags less often. The BPI and OK Compost INDUSTRIAL certifications mean it is accepted at most municipal composting facilities. One catch identified by reviewers: heavy, wet loads can push the bag to break down faster, so keep it away from direct heat and do not let liquids sit in it for days. It is a strong choice for anyone with a full-size bin who wants fewer trips to the curb.
Why It Holds Up
- 0.87 mil thickness resists tearing from sharp waste like eggshells
- 50 bags per roll offer good value for a premium 13-gallon liner
- BPI and OK Compost certifications cover most composting programs
A Few Limits
- Not designed for extended wet waste storage without risk of breakdown
- 50-count pack may run out fast for high-volume households
The pick for full bins: If you fill a standard 13-gallon kitchen can and want a bag that does not tear on the way out, this is your reliable daily driver.
A quick heads-up: The material has a slight corn-derived scent some users notice when new — it fades once the bag is in the bin.
2. UNNI Compostable Trash Bags, 2.6 Gallon / 9.84 Liter, 100 Count
A 100-bag roll of countertop-sized liners that combine solid strength with a proven certification track record.
Designed for small 2.6-gallon / 9.84-liter bins, these 16.3-inch by 16.5-inch bags slide into compact countertop compost pails without bunching at the rim. The 0.71 mil thickness handles daily peels, eggshells, and coffee filters — owners mention they are “extra thick, strong, no tearing or leaking” for routine food waste. That is a meaningful difference from thinner no-name brands that split under the weight of wet scraps. The 100-bag count is 100 bags versus Cleanomic’s 25-bag pack, though those are a much larger size, so you are not comparing apples to apples on volume alone.
UNNI carries three certifications: BPI (industrial composting to ASTM D6400), CMA (field-tested in operating facilities), and OK Compost HOME (backyard pile safe) — one of the few bags on this list with both home and commercial approval. This matters if your local program requires one specific standard. One reviewer noted the bag “tears very easily even with light use” in a minority review, but the overwhelming majority rate it 5 stars for reliability at this size. It is the best-value small bin liner for someone who wants a trusted name and a high bag count per box.
Strengths
- Three certifications cover nearly every composting scenario
- 100 bags per roll means fewer reorders
- 0.71 mil is thick enough for typical countertop waste
Drawbacks
- Not suitable for heavy or sharp items like large melon rinds
- Must be stored in a cool, dry place and used within 9 months
Best for regular composters: If you empty a small bin every 2-3 days and want bags that actually degrade in your backyard pile, this is the smart, low-cost choice.
Not ideal for: Heavy wet loads that sit for a week — the 0.71 mil can break down if moisture collects too long.
3. ecobewus 2.6 Gallon 100% Compostable Bags Handle Tie (110 Bags)
A handle-tie bag designed so you cinch, lift, and go without fumbling with a twist-tie.
This 2.6-gallon bag comes with integrated handle ties — think grocery bag handles that you pull together to close — which makes it far easier to carry a full load to the outdoor bin compared to open-top liners that require a separate twist-tie or knot. The ecobewus bag measures 22 inches by 16 inches, a bit taller than the UNNI at 16.3 by 16.5 inches, and customers note the handles are “worth the extra cost” for long-term convenience. A star-seal bottom distributes weight evenly, which helps reduce the chance of leaks that happen when wet scraps pool in one corner.
It holds the same 2.6-gallon capacity as the UNNI but packs 110 bags per box versus UNNI’s 100-count — a small edge for buyers who go through bags quickly. The eco-bewus line carries both BPI (ASTM D6400) and TÜV Austria OK Compost Home certifications, so it works in industrial facilities and backyard piles. The manufacturer notes to avoid placing hot or excessively wet food waste directly in the bag to prevent leaks, which is a fair trade-off for a plant-based liner. This is the pick for anyone who prioritizes quick, mess-free closing over raw thickness.
Why Handles Help
- Handle ties eliminate the need for separate closures
- Star-seal bottom reduces leak risk from pooled moisture
- 110 bags add a small count advantage over standard 100-packs
Limitations
- Taller bag may not fit very short countertop bins without folding over
- Wet heat can weaken the bag faster than thicker 0.87 mil options
Grab this for daily convenience: If tying a knot is a chore you would rather skip, the handle-tie design saves you time every single trip to the bin.
Watch out for: The bag is slightly taller than some 2.6-gallon containers, so measure your bin’s height first.
4. TERRACOR 3 Gallon Compostable Food Scrap Bags, 100 Bags
A 3-gallon liner that is actually the right size for a 1.3-gallon countertop bin when you fold the edge over.
The TERRACOR bag measures 16.9 inches by 17.7 inches, while the UNNI 2.6-gallon bag measures 16.3 inches by 16.5 inches, giving you a bit more room for bulky scraps like corn cobs or melon rinds. But here is the practical detail that matters: reviewers point out this bag is a “perfect size for 1.3 gallon countertop bin” — meaning the 3-gallon capacity is ideal when you fold the top lip over the rim, giving you a snug fit without excess bag flapping around. It handles fruit peels, coffee grounds, and plant trimmings without leaking, and one buyer mentioned it freezes without tearing if you store scraps in the freezer before collection day.
It is BPI certified to ASTM D6400, so it is accepted in California and other strict composting programs. The bags are made from plant-based PLA and PBAT — a material combo that balances strength with compostability. The maker recommends storing bags in a cool, dark place and using them within a year of purchase. This is a straightforward, no-gimmick pick if your bin is smaller than the bag’s nominal rating and you just want a liner that fits, holds, and ties up cleanly.
What Works
- 16.9 x 17.7 inches gives good over-the-rim coverage for compact bins
- BPI certified for industrial composting programs
- Freezer-safe without cracking under frozen waste
What Does Not
- Smaller than expected for a 3-gallon rating when used alone
- Thickness not listed on the spec sheet, so durability is a hands-on judgment
The fit-focused choice: If your countertop bin is 1.3 gallons and you are tired of bags that hang too loose or too tight, this liner folds over the rim without fuss.
One trade-off: The bag fills quickly — expect to empty it every day or two with a busy kitchen.
5. HECTOLIFE 13 Gallon Compostable Trash Bags with Drawstring, 100 Count (2 Rolls)
A double-layer drawstring 13-gallon bag sold in a bulk 100-count pack for heavy kitchen users.
If you cook a lot and fill a 13-gallon can every few days, the HECTOLIFE 100-count two-roll pack keeps you stocked for a couple of months. The bags measure 24 inches by 30 inches, slightly shorter than the ECOLipak 24 x 32.28 inches, but the thickened design is built to resist tearing and leaking under regular kitchen waste. Shoppers say it is “thick, sturdy, no leakage for a compost bin” and that the drawstring “works just like the plastic ones” for easy tying and lifting. A strong drawstring is a genuine upgrade over open-top bags that require a separate tie or knot.
The bag is made from plant starch (corn) material and carries BPI, OK Compost, and Seedling certifications — a triple badge that covers industrial and European composting standards. One common complaint from reviewers is that the top of the bag can feel tight with little give, making it harder to fit over some 13-gallon bins. You may need to stretch it carefully around the rim. The perforation between bags is also tight — some users advise using scissors to separate them rather than pulling, which can stretch weak spots. For the bag count and drawstring convenience, it is a solid bulk buy for a busy kitchen.
Why Bulk Works
- 100 bags in two rolls means fewer reorder cycles
- Double-layer drawstring makes closing and carrying straightforward
- Three certifications ensure broad composting acceptance
The Annoyances
- Top of bag fits tightly — may not drape easily over bin rim
- Perforations are poor; plan on using scissors to separate bags
Great for volume: If your household goes through a 13-gallon bag every 2-3 days, the 100-count keeps you running without thinking about restocking.
Watch for the fit: Measure your bin’s perimeter — HECTOLIFE recommends round cans under 15.3 inches diameter or rectangular bins with a perimeter under 48 inches.
6. Cleanomic Compostable* Trash Bags with Drawstring (13 Gallon, 25 Units)
A silky-smooth 13-gallon bag that feels more like plastic than plant material — but still composts.
Cleanomic took a different approach: instead of the crinkly, stiff feel typical of PLA and PBAT bags, this liner is powder-free and fragrance-free with what the maker describes as a “silky-smooth” texture that slides over the rim and tucks in without fighting you. At 13 gallons, it fits standard tall kitchen cans, and the drawstring closure keeps the bag secured around the bin. Buyers report it is “heavy duty, doesn’t tear when removing from roll or tying full bag,” and some say they use it “exclusively instead of plastic trash bags.”
The catch: it is a 25-count pack, which is a 50-bag gap compared to the ECOLipak’s 50-count (and a massive 75-bag gap compared to HECTOLIFE’s 100-count). If you fill a bag daily, you reorder every three weeks. Additionally, about one in five reviews mention the bag tends to slide off the rim when anything heavy is placed inside — a direct result of the smooth material that makes it feel nice but reduces friction against the can. Cleanomic recommends use within 6 months of purchase and storage away from direct heat. For someone who values feel and wants to minimize plastic use, this is the premium touch choice.
Feel and Performance
- Silky texture is noticeably easier to handle than stiff compostable bags
- Drawstring ties securely for easy knot-tying
- Heavy-duty construction holds up during daily use
Realities to Know
- 25-count pack means frequent reordering for busy kitchens
- Bags slip off the rim of some cans when loaded with heavy waste
Best for feel-focused buyers: If you dislike the crinkly sensation of standard compostable bags and want a smooth drawstring liner that handles daily waste, this is the most pleasant bag to touch on this list.
Reconsider if: You fill a 13-gallon can more than twice a week — the 25-count will have you reordering too often to be practical.
Understanding the Specs
Mil Thickness
Mil is a unit measuring one-thousandth of an inch, used to describe bag thickness. A 0.71 mil bag is the baseline for light kitchen scraps, while 0.87 mil bags handle wetter loads and sharp items like melon rinds with fewer punctures. The thicker the mil, the less likely the bag will tear when lifted full of heavy waste.
BPI vs. OK Compost HOME Certification
BPI (Biodegradable Products Institute) certification means the bag will break down in a commercial composting facility that maintains high temperatures for a set time. OK Compost HOME certification from TÜV AUSTRIA means it composts in a cooler backyard pile. If your town’s composting program requires one specific certification, check the bag’s label before buying — the wrong one could mean your bag gets rejected.
