Lightweight, Tamper-Proof Poly Mailers for Postal, Courier & E-Commerce Dispatch
The growth of e-commerce has transformed how products move from businesses to customers—and packaging is now a direct extension of your brand experience. Polycreations Pvt Ltd’s mailing and e-commerce bags are engineered to protect goods throughout the entire logistics journey—waterproof, tamper-evident, tear-resistant, and fully customisable to reflect your brand identity.
Whether you’re an online retailer, distributor, or business managing high-volume shipments, our poly mailers are designed to perform at every scale and price point—without compromising on protection or presentation.
Product Overview
Poly mailing bags—also known as poly mailers, courier bags, or e-commerce dispatch bags—are lightweight, flexible polyethylene envelopes designed for the demands of postal and courier transportation. They are widely used for shipping a variety of non-fragile goods and documents, combining reliable protection with minimal weight and cost efficiency.
Key Features
100% Waterproof
Full protection against rain, moisture and humidity throughout the postal journey — your products arrive dry and undamaged regardless of transit conditions.
Tamper-Evident Self-Seal Closure
Integrated permanent pressure-sensitive adhesive strip provides a fast, clean, tamper-evident seal — any attempt to open the bag leaves visible evidence of tampering, protecting both sender and recipient.
Tear & Puncture Resistant
Multi-layer LDPE construction delivers outstanding resistance to tearing, puncturing and rough handling on courier conveyor systems and during manual sorting.
Fast Packing Line Performance
The integral self-seal strip eliminates the need for heat sealing equipment — dramatically speeding up dispatch operations on high-volume packing lines.
Full Custom Branding
Up to 6-colour flexographic printing — your logo, brand colours, website, social handles, return address and promotional messaging all printed directly onto the bag. Turn every delivery into a brand moment.
Return-Ready Design
Designed for seamless returns, our mailers feature dual adhesive seals and easy-tear perforation, allowing the bag to be securely reused—reducing waste while improving customer convenience.
