How to Specify Custom Poly Mailers
Custom poly mailers reduce parcel weight for apparel, textiles and other non-fragile e-commerce products. A useful specification states the finished internal size, film structure and thickness, opacity, seal design, print coverage and whether a permanent or returnable closure is required. The mailer should be tested against the actual product and fulfilment process rather than chosen by outside dimensions alone.
Film, Closure and Print Choices
Co-extruded polyethylene film combines a printable outer surface with an opaque inner layer. Film thickness affects puncture resistance, feel and material consumption; the correct value depends on product edges, parcel weight and the handling route. A permanent self-seal strip is standard for outbound shipping, while a second tear strip can support customer returns. Full-coverage colour, warning text, barcodes and writable areas should all be defined in the artwork brief.
When a Bubble Mailer Is Better
Flat poly mailers suit soft goods that do not need cushioning. Cosmetics, electronics accessories and other impact-sensitive items may need a bubble-lined envelope or a box instead. Before ordering, test sealing performance, tear resistance, barcode scanning and pack speed with production-equivalent samples.
