These 14.5" x 19" poly mailers are engineered for large apparel fulfillment, outerwear, and bulkier soft-goods shipments. Co-extruded at 2.5 mil, they deliver enhanced tear resistance, water resistance, and a tamper-evident seal — without the perforated opening strip found on standard mailers, providing a stronger seal zone at the top closure.

Features

• Not perforated — stronger top closure area versus tear-strip mailers


• Co-extruded construction — multi-layer film for enhanced strength and durability


• Tamper-proof — self-sealing adhesive closure shows evidence of opening


• Water-resistant — opaque white exterior protects contents from moisture exposure


• White/silver colorway — opaque for contents privacy, professional shipping appearance

Material Notes

Co-extruded poly mailers are manufactured by simultaneously extruding two or more layers of polyethylene film into a single bonded sheet. This multi-layer process produces a film with greater tensile strength, puncture resistance, and moisture barrier performance compared to single-layer polyethylene at the same gauge. The white exterior and silver interior construction is fully opaque for shipping privacy.

Use Case Notes

The 14.5" x 19" format accommodates standard folded outerwear, jackets, and adult-size tops and bottoms. The non-perforated design means the top closure area has no weakened strip, providing a stronger overall envelope for heavier or bulkier items. Tamper-evident adhesive closure is appropriate for direct-to-consumer orders where shipment integrity is required.

Common Questions

Q: What is the difference between perforated and non-perforated poly mailers?
A: Non-perforated mailers have a solid top closure area with no tear strip. This provides a stronger seal zone, making them better suited for heavier or bulkier items where seal integrity is critical. Perforated mailers include a tear strip for easier opening by the recipient.

Q: Is the adhesive strip single or double-use?
A: The self-sealing adhesive is a single-use tamper-evident closure. Once sealed, the adhesive shows evidence of opening if disturbed.

Q: Can these mailers be run through an automated bagging line?
A: These are designed for manual fulfillment operations. For automated bagging lines, machine-grade mailers with specific feed tolerances are recommended.
