How to Specify Custom Compostable Mailing Bags
Define usable internal size, film thickness, certification requirement, opacity, closure strips, artwork, quantity, storage conditions and destination market. Test product fit, seals, puncture resistance, label adhesion and barcode scanning, and approve the exact environmental claim before bulk production.
Buyer Questions
- Are biodegradable and compostable mailers the same?
- No. Compostable claims should reference a relevant standard and clearly state the intended composting conditions; generic biodegradable wording is not equivalent.
- What information is needed for a quote?
- Send usable size, thickness, certification requirement, closure, print coverage, quantity, packing, storage expectations and delivery destination.
- What should be tested before production?
- Test packed-product fit, seals, puncture resistance, label adhesion and barcode scanning on a production-equivalent sample.
