Common questions
Are these mailers truly waterproof and moisture-resistant?
Yes. The 2.5 mil polyethylene construction provides complete moisture and water barrier protection, making these ideal for products sensitive to humidity or shipping conditions. The self-seal closure prevents water infiltration at the seam.
Will labels and branding adhere properly to the white surface?
Absolutely. The white exterior is specifically formulated for excellent label, stamp, and ink adhesion. This makes custom branding, barcodes, and tracking labels fit into your unboxing experience.
How does the tear-strip self-sealing mechanism work?
Simply peel back the integrated tear strip to reveal the self-adhesive strip, align the flap, and press to seal. No tape, glue, or additional materials needed, this accelerates packing speed while ensuring consistent, tamper-evident closures.
Can these mailers handle overpacked or heavy items?
Yes. The high-strength polyethylene seams are engineered to resist tearing and puncturing even when contents exceed typical weight expectations. The 2.5 mil thickness provides structural integrity without excessive bulk.
