Poly Mailers

Poly mailers—also referred to as mail bags, poly mailer bags, or shipping bags—are lightweight plastic packaging supplies perfect for shipping durable and soft goods such as apparel, blankets, toys, purses, and more. They are made of LDPE polyethylene, which makes them waterproof and tamper-resistant, and they have convenient self-sealing adhesive closures.

In general, poly mailers are cheaper to ship than boxes. The product is less expensive than shipping boxes and paper mailers, and because they are made of lightweight materials, the cost of shipping them to your warehouse is also low. On top of this, it adds very little weight to your outbound shipments. They often offer the most cost-effective choice for shipping soft or durable items.

Poly mailers have a lower carbon footprint per shipment and require less energy to produce. Paper mailers, however, may be preferred for certain brands or local recycling goals — EcoEnclose offers both so you can choose what’s best for your operations.

Our standard recycled poly mailers available on this page are consistent in color (ivory or gray), smooth in texture, and have a more premium feel than our RCS100-certified poly mailers. If your brand prefers or requires third-party certification, our RCS100-certified mailers might suit you, but the are only available in a single off-white color with a slight gray tint. Also, they have some texture and gelling inconsistencies and a somewhat brittle feel. Finally, our RCS100-certified poly mailers are slightly more expensive than our standard offering.

To summarize, if RCS certification is important, choose RCS100-certified poly mailers. If cost, texture, or color consistency is most important, choose our standard recycled poly mailers. We stand behind all of our poly mailer options. Learn about our sustainability commitment.

For best results, remove the label before recycling. However, most recycling facilities can process small amounts of adhesive residue without contamination concerns.
