Product Specifications

What Are Poly Mailing Bags?

Poly Mailing Bags are plastic shipping envelopes manufactured from durable polyethylene films. Unlike cardboard boxes, these mailers provide a lightweight packaging solution that minimizes shipping costs while maintaining excellent product protection.

The bags feature a strong self-adhesive closure strip that creates a tamper-evident seal after packaging. Once sealed, the package cannot be opened without visible damage, helping improve shipment security.

Poly mailers are commonly used to package:

• Clothing and apparel
• Fashion accessories
• E-commerce products
• Documents and catalogs
• Soft goods
• Promotional items
• Small retail products

Key Features of Poly Mailing Bags

Strong Self-Sealing Adhesive Closure

Each poly mailing bag is equipped with a high-strength adhesive strip designed to create a secure and permanent seal. This feature eliminates the need for additional tape and speeds up packaging operations.

Waterproof Protection

Polyethylene film provides excellent protection against rain, humidity, spills, and dust during transportation. This helps ensure products arrive in perfect condition.

Lightweight Construction

One of the biggest advantages of poly mailers is their low weight. Businesses can significantly reduce shipping costs compared to traditional corrugated boxes.

Tear and Puncture Resistance

Premium polyethylene materials provide outstanding durability and resistance to tearing, punctures, and rough handling throughout the shipping process.

Flexible and Space-Saving

Poly mailing bags require minimal storage space before use, helping warehouses optimize inventory management and reduce storage costs.

Custom Branding Opportunities

Custom printed poly mailers can be produced with:

• Company logos
• Brand colors
• QR codes
• Promotional messages
• Marketing graphics
• Return instructions

Custom packaging helps strengthen brand recognition and enhances the customer unboxing experience.
