Common questions
Are these mailers waterproof and suitable for products sensitive to moisture?
Yes. The 2.5 mil polyethylene construction provides water and moisture resistance, protecting contents from humidity, rain, and spills during transit. The sealed closure prevents water ingress, making these ideal for cosmetics, electronics, and other moisture-sensitive items.
Can I apply custom labels, stamps, or branding to these mailers?
Absolutely. The white outer surface is designed for excellent label, stamp, and ink adhesion. You can apply custom logos, barcodes, return labels, and tracking information without compromising seal integrity.
Do these mailers require tape or additional sealing materials?
No. The integrated self-seal adhesive strip means you simply press and peel to close, no tape, staples, or additional materials needed. This reduces packaging costs and accelerates your fulfillment process.
What makes these mailers puncture and tear resistant?
The 2.5 mil polyethylene film combined with high-strength seams resists puncturing, tearing, and damage from rough handling. The silver inner lining adds durability and prevents product visibility while maintaining professional appearance.
