Design for APR, Then Communicate Clearly
To improve outcomes for plastic packaging for food, design to APR “Preferred” features first, then convey disposal steps with How2Recycle where appropriate. This aligns technical performance with the real-world system, improving bale quality and consumer participation. APR Design® Digital Tool
What U.S. Regulators Expect on Recycling Claims
As you market plastic packaging for food, make sure “recyclable” isn’t just a symbol. The FTC Green Guides and California’s SB 343 require substantiation based on actual access and processing—not theoretical recyclability—so legal, packaging, and ESG teams must stay aligned.

Practical U.S. Checklist for New SKUs
For any new plastic packaging for food, follow a standard checklist: confirm 21 CFR status or FCS route, verify supplier documentation and LNOs where applicable, specify OTR/WVTR targets via ASTM methods, test seal integrity, run APR sortation/compatibility checks, and finalize consumer-facing labels per FTC/How2Recycle.

Final thought
Plastic packaging for food can be safe, more recyclable, and better designed when you connect compliance science (FDA), system compatibility (APR/How2Recycle), and truthful claims (FTC/CalRecycle). Treat packaging as part of product quality—engineer barriers and seals for shelf life, then tune components for U.S. recyclability and transparent consumer guidance. APR Design® Guide: Start Here
