CERTIFICATIONS
Certifications explained
EN 13432 — EU Compostability Standard
The harmonised European standard: 90%+ biodegradation within 6 months, plus disintegration and ecotoxicity limits. The basis for EU compostability claims and Single-Use Plastics Directive compliance.
ASTM D6400 (BPI) — North American Compostability Standard
The US reference standard for compostable claims, verified through BPI certification: 90%+ biodegradation within 180 days, plus disintegration and ecotoxicity limits. The basis for US and Canadian compostable claims.
OK Compost HOME — TÜV Austria
Home-compostability mark: verified to biodegrade at ambient temperatures in a backyard pile within 12 months — the strictest end-of-life standard a shopping bag can carry.
AS 5810 — Australian Home Compostable
The Australian home-compostability standard, required for compostable claims in AU/NZ retail. Same 12-month home-compost performance, audited annually.

HONEST TRANSPARENCY
Limitations & Storage
Not recommended for sustained contact with liquids above 60°C (140°F). The bag will begin to soften at elevated temperatures. For hot-food applications, consider our ES-SB-04 extra-thick reusable line rated for brief hot contact.
FAQ
Frequently asked questions
How does the 12lb rating compare to standard HDPE grocery bags?
Standard HDPE T-shirt bags typically rate at 10–15 lbs, so the ES-SB-01 sits squarely in the same performance class. The key difference is end-of-life: our bag returns to soil in 12 weeks rather than persisting for centuries.
Can these bags be stored like conventional plastic bags?
Yes — store in a cool, dry environment away from direct UV. Shelf life is 12 months from date of manufacture. Avoid prolonged exposure to temperatures above 40°C (104°F) as this may accelerate the biodegradation trigger.
Are the inks and adhesives also compostable?
Water-based, soy-derived inks are standard for all custom printing. Adhesives used in seam sealing are certified compostable under EN 13432. No petroleum-derived additives are used anywhere in the construction.
What is the difference between home-compostable and industrial-compostable certification?
Industrial compostability (EN 13432, OK Compost INDUSTRIAL) verifies breakdown at 58°C inside a managed facility; home compostability (OK Compost HOME, AS 5810) verifies breakdown at ambient backyard-compost temperatures within 12 months. ES-SB-01 holds both certifications, so the bag biodegrades whether it reaches a municipal facility or a home compost pile.
How does California's SB 1053 affect compostable checkout bags?
SB 1053, effective January 1, 2026, amends SB 270 so that no film plastic shopping bags — including certified compostable film — may be provided as checkout bags in California. For California checkout, paper bags or reusable totes are the compliant formats. Outside California, and wherever programmes permit certified compostable checkout bags, ES-SB-01 carries the full EN 13432, ASTM D6400 (BPI), and OK Compost HOME documentation pack for your compliance team.
