Custom Poly Mailer Bags for E-Commerce, Apparel and Courier Shipping
Custom poly mailer bags provide a lightweight and practical packaging solution for e-commerce sellers, apparel retailers, fulfillment centers, distributors, and courier packaging projects.
The bag uses a flexible polyethylene structure combined with a self-sealing adhesive closure. Products can be inserted quickly, the release liner removed, and the flap pressed down to complete packing without additional tape.
Compared with corrugated cartons, poly mailers reduce packaging volume and are particularly suitable for soft or non-fragile products such as clothing, textiles, fashion accessories, documents, and selected consumer goods.
The product can be customized in different sizes, film thicknesses, exterior colors, interior colors, adhesive structures, printed artwork, barcodes, warning text, QR codes, and packaging methods.
