BPI Certified Compostable Bags — Torise

What Our BPI Finished Product Certification Means for Your Supply Chain

When North American retailers, brands, or regulators review compostable packaging, they require certification on the finished product—not just the resin. Torise holds BPI certification for our finished compostable bags, verified under ASTM D6400 standards, covering natural, red, yellow, white, black, and green bags with multi-colour print, up to 135 µm thickness.

This certification confirms that our finished bags—not just the raw material—are scientifically proven to biodegrade in commercial composting facilities. It provides our North American buyers with the credible, third-party validation required to carry the BPI logo on finished packaging and meet retailer, brand, and regulatory requirements.

What BPI Finished Product Certification Covers

Certification covers finished bags with multi-colour printing. All colours and printed designs within the certified scope are covered.

BPI Certified Compostable Resin — Torise

For film converters and packaging manufacturers supplying the US market: In North America, BPI certification is the working compliance baseline for compostable packaging.

Major retailers, US state procurement programs (California, Washington, Oregon), and commercial composting facilities use the BPI mark as their acceptance filter — without it, products are typically rejected regardless of biobased content claims.

Torise holds BPI resin certification for our compostable resin grades (Natural, Red, Yellow, White, Black, Green), tested against ASTM D6400 — the US standard for plastics designed to compost in municipal and industrial composting facilities.

Why ASTM D6400 — and What It Requires

ASTM D6400 requires that materials achieve at least 90% biodegradation (conversion to CO₂) within 180 days under industrial composting conditions, with no ecotoxicity in the resulting compost. Each product is certified only up to the tested thickness — a product reformulated to be thicker than its certified version is no longer covered.

BPI certification is valid for three years and involves independent laboratory testing, application review, and ongoing market surveillance. The full certification process typically takes several months from application to certified product.

EN 13432 Certified Compostable Resin — TRBF

For film converters and packaging manufacturers: The TRBF resin is EN 13432-certified at the material level. If you use it to produce film, you're starting with a material that already meets European compostability standards — which can reduce the scope of your own finished-product testing.

What This Saves You

• Testing scope — starting with certified material reduces the variables in your own EN 13432 testing


• Compliance timeline — the resin already has third-party verification, so your path to finished-product certification is shorter


• Documentation — we provide full test reports and technical data sheets for your regulatory files

OK Compost HOME Certified Compostable Bags — Torise

What Home Compostability Actually Means

Most "compostable" packaging claims refer to industrial composting — high-temperature facilities that process waste under controlled conditions. But what if your customer doesn't have access to one? What if the bag ends up in a backyard bin?

OK Compost HOME certification answers that question. It verifies that a product will biodegrade in a home compost environment — ambient temperature, variable conditions, no industrial controls. It's a higher bar, and a growing number of European retailers now require it for packaging that consumers will dispose of at home.

Why This Matters for Your Business

What the Certificate Covers

This is a finished-product certificate, which means:

• Shopping bags (check-out bags) — certified as a finished product, ready for retail


• Produce bags — for loose fruit and vegetables


• Organic waste collection bags — for home composting programs


• Coloured printing — inks and processes are included in the certification scope


• Up to 60 µm thickness — covers most standard bag applications

Important: This is not a "resin-only" certificate. The finished bag — including printing, colour, and structure — has been tested and verified by TÜV Austria.
