Low Density HDPE Poly Mailers 10×13 | Waterproof & Durable Shipping Envelopes | Eco-Friendly & Bulk Wholesale

Core Features

1. Waterproof & Moisture-Proof

The HDPE film blocks water vapour and liquids, protecting documents, clothing and non-electronic goods from rain and humid conditions in transit.

2. Puncture- & Abrasion-Resistant

High-strength HDPE resists friction, squeezing and minor punctures, reducing damage, returns and exchanges during shipping.

3. Lightweight to Cut Shipping Costs

The low-density material keeps each envelope light, trimming package weight and freight spend for high-volume shippers.

4. Self-Adhesive Seal for Fast Packing

No tape or heat sealing needed: drop the item in and press the self-adhesive strip to finish packing.

5. Highly Recyclable

HDPE is the widely recycled #2 plastic and is easier to recycle than composite materials or bubble-wrap packaging.

6. Thin & Flat, Space-Saving

The ultra-thin envelope stacks flat, so it saves storage space before and after use.

7. Custom Printing & Bulk Supply

A clean, professional surface for logos and brand information; bulk wholesale with unprinted stock for rapid shipping, plus factory-direct customization.
