What are Poly mailers for ecommerce?
Poly mailers for ecommerce (also known as plastic shipping bags, mailing bags, or ecommerce courier bags) are lightweight packaging bags made from polyethylene (PE) material. They are widely used in ecommerce shipping, logistics, and retail packaging.
Poly mailers are mainly used as an alternative to cardboard boxes. They help reduce shipping costs while improving packing efficiency. The outer surface can be custom printed with logos to enhance brand identity and professional appearance.
Key Features
- Lightweight & Cost-Saving — Significantly lighter than cardboard boxes, reducing dimensional weight and lowering shipping costs per order.
- Waterproof & Moisture-Resistant — Seals out rain, moisture and dust, keeping contents dry and pristine during transit.
- Tear & Puncture Resistant — Strong, durable film protects products from rough handling and damage.
- Tamper-Evident Self-Seal Closure — Pressure-sensitive adhesive strip with tamper-evident design for secure, worry-free sealing.
- Fully Customizable — Custom sizes, thickness and full-color printing (logos, brand messages, barcodes) to reinforce your brand identity.
- Eco-Friendly Options Available — Recyclable, recycled-content and biodegradable materials to support your sustainability goals.
