Compostable Trash Bags

Compostable Trash Bags are the workhorse SKU for waste programs and municipal organics. Pure Compostables manufactures the full range from BPI-certified plant-based PLA/PBAT. 16 stocked SKUs cover the full trash bags range.

What sets our trash bags apart

Right-thickness for waste type. 0.65 mil for light dry waste, 0.85 mil for kitchen organics, 1.0–1.2 mil for commercial loads.
Drawstring closure. Integrated PLA/PBAT drawstrings reduce spillage during transfer.
Puncture-tested. Wall thickness validated for typical commercial-volume loads.
Municipal program compatibility. BPI + EN 13432 + ASTM D6400 — accepted by most US, EU, UK, and Australian municipal organics programs.

Who buys our trash bags

Municipal organics programs

City-run curbside organics collection. Bags must meet program-specific certification (typically BPI in the US, EN 13432 in EU).

Commercial foodservice

Restaurants and cafeterias separating food waste at-source. Heavier-thickness bags (0.85–1.0 mil) handle wet kitchen organics.

Residential eco-conscious brands

Direct-to-consumer home-composter and waste-bag brands. Often want printed, branded bags.

Hospitality & hotels

Daily housekeeping bag swaps. Standard 13- to 30-gallon bags in case quantities.

Certifications and compliance

Standards compliance: BPI (US), EN 13432 (EU), ASTM D6400, ISO 17088, and DIN CERTCO. These are the credentials procurement and compliance teams typically request when evaluating compostable suppliers. We provide verifiable certificate numbers, lab test reports, and material safety documentation.

Related ranges and sub-categories

This is one branch of the broader Bags range. Other related sub-categories:

OEM, private label, and bulk orders

Standard sizes ship from inventory; OEM, ODM, and private-label runs with custom dimensions and branded artwork ship factory direct from our Shenzhen facility. Print methods include flexo (volume-cost efficient at 10,000+ units), digital (short-run / multi-SKU / seasonal artwork), and embossing (premium-positioned items). All inks are food-safe and either water-based or UV-cured — both compost end-to-end.

Frequently asked questions about trash bags

What thickness do I need for my use case?

Light dry waste tolerates 0.65 mil; wet kitchen organics need 0.85–1.0 mil; heavy commercial waste needs 1.0–1.2 mil. Read our trash bag size guide for a full sizing matrix.

Does the drawstring also compost?

Yes — drawstrings are made from the same PLA/PBAT blend as the bag body, so the entire bag composts as one unit.

Will these tear if I overfill?

Bags are rated for typical loading per thickness. 1.2 mil handles up to 30–40 lb commercial loads; for heavier specs, contact our team.

Are they BPI certified?

Yes — BPI + EN 13432 + ASTM D6400. Most municipal organics programs accept BPI-certified items; check your local program for specifics.

Can we get printed/branded bags?

Yes — OEM and private-label runs from 5,000 bags. Pantone color-matching available.

How long is the shelf life?

12–18 months in cool, dry storage out of direct sunlight. Compostable bags break down faster in heat and humidity.

Will they break down in my home compost pile?

No — industrial composting only. PLA/PBAT needs sustained 55–60°C and active microbial activity, conditions home compost piles don’t typically reach.

Do you ship internationally?

Yes — worldwide shipping by case, pallet, or full container. Lead time 4–8 weeks depending on order volume.
