Poly Mailers - Not Perforated, 2.5 Mil 10" x 13
Heavy-duty 2.5 mil co-extruded poly mailers for shipping apparel, soft goods, and e-commerce fulfillment orders requiring a durable, opaque, water-resistant outer envelope. The white exterior provides a clean surface for labels and branding, and the silver interior blocks contents from view. Non-perforated construction adds structural integrity compared to tear-strip mailers.
Specs: 10" x 13" | 2.5 mil | Co-Extruded Polyethylene | White Exterior / Silver Interior | Tamper-Proof | Water-Resistant
Applications
Used by apparel brands, subscription box operations, and e-commerce fulfillment centers for shipping folded t-shirts, lightweight garments, accessories, and soft goods. Also used for catalog and print mail distribution, returns packaging in retail logistics, and general direct-to-consumer fulfillment where a professional presentation mailer is required without a tear-open perforation.
Features
- Not perforated — extra structural durability compared to tear-strip mailer formats
- 2.5 mil co-extruded construction — heavy-duty for transit-resistant shipping
- Opaque white exterior / silver interior — obscures contents for privacy and security
- Tamper-proof construction — visible evidence of tampering if opened in transit
- Water-resistant — protects contents from moisture during standard shipping conditions
- 10" x 13" format — accommodates folded t-shirts, accessories, and small soft goods
Material Notes
Co-extruded polyethylene construction combines multiple layers into a single unified film for improved tear resistance and seal strength compared to mono-layer poly mailers. 2.5 mil nominal gauge provides heavy-duty performance for multi-stop parcel handling. The opaque white and silver co-extrusion is a privacy and security standard for direct-to-consumer shipments.
Use Case Notes
The 10" x 13" format accommodates a standard folded adult t-shirt with adequate margin for sealing. It also fits folded lightweight sweaters, scarves, accessories, and small document sets. The non-perforated opening is preferred in applications where the recipient will cut or tear the bag rather than use a pre-cut pull strip, or where the extra material at the seal line adds mechanical strength during pallet or bin handling.
Common Questions
Q: How does non-perforated differ from standard poly mailers?
A: Standard poly mailers often include a perforated tear strip so the recipient can open the mailer cleanly. Non-perforated mailers omit this strip, which increases seal-area strength and eliminates the risk of accidental tear-line opening during sorting or transit.
Q: Are these tamper-evident?
A: Yes. The tamper-proof construction shows visible evidence if the mailer is opened before delivery, which is a standard security requirement for direct-to-consumer apparel and subscription box fulfillment.
Q: Are these water-resistant for all weather conditions?
A: The co-extruded poly construction provides resistance to typical rain and moisture exposure during standard parcel transit. Extended submersion or high-volume water exposure is not within the design scope.
Why Source These Mailers
Non-perforated construction increases durability for high-handling-count fulfillment operations. 2.5 mil heavy gauge reduces damage claims for high-value soft goods. White exterior and silver interior combination provides the professional presentation standard expected in direct-to-consumer e-commerce shipping.
