These 12 x 15.5 inch poly mailers are built from 2.5 mil polyethylene incorporating 50% post-consumer recycled (PCR) content — reducing virgin plastic demand without compromising durability. The non-perforated lip style uses a self-seal adhesive closure that requires no tape or heat equipment, and the white exterior accepts labels, stamps, and direct ink without pretreatment.

The silver inner lining provides an additional barrier layer, while high-strength seams hold under load including overpacked conditions. Moisture, puncture, and tear resistance make these mailers reliable for e-commerce fulfillment, retail replenishment, subscription box shipping, and direct-mail distribution where lightweight, flexible packaging is preferred over rigid corrugated.

The 50% PCR designation supports sustainability reporting and recycled-material procurement compliance. Sold in cases of 500 and ships via parcel carrier.
