40x55cm PLA PBAT Waterproof Compostable Shopping Bags Self Seal Postage Bags Biodegradable

Compostable Express Shipping Bag 40x55cm PLA PBAT Waterproof Self Seal Mailing Bag

Product Description:

Bulky online orders and multi item shipments need a large, weatherproof mailer. This 40x55cm biodegradable shopping bag is blown from PLA and PBAT resin as an express shipping bag for clothing bundles, bedding and bulky parcels.

The film holds a single side thickness of 0.032mm (3.2 silk) for a waterproof, dust resistant outer that shields goods in transit. Once discarded it breaks down by microbial action under compostable conditions into carbon dioxide, water and biomass rather than persistent plastic waste.

Made with no PE and no photo-oxidative additive, the mailer complies with GB/T 20197-2006 degradable plastics standard and is backed by a third party test report. The opaque film also keeps parcel contents private.

A full width self seal strip closes bulky parcels fast, and heat cut edges stay strong through handling. Custom printing up to 8 colors puts the brand, barcode and handling marks on every shipment.
