Common questions
Will these mailers protect my products from moisture during shipping?
Yes. The 2.5 mil polyethylene construction is water and moisture resistant, protecting contents from rain, humidity, and ground conditions. However, these are not fully waterproof, for fully submersible protection, consider additional cushioning or upgrade to heavy-duty mailers.
Do I need tape to seal these mailers?
No. The integrated self-seal adhesive strip requires only pressure to activate, press and seal in seconds. This eliminates tape costs, speeds fulfillment, and creates a professional, branded appearance without visible adhesive.
Can I print labels and stamps on these mailers?
Yes. The white outer surface is designed for excellent label and ink adhesion. Integrate barcode labels, shipping stamps, or custom branding directly onto the mailer for efficient tracking and professional presentation.
What happens if my package is overstuffed?
The high-strength seams are engineered to withstand overpacking without bursting or opening during transit. The 2.5 mil polyethylene also provides tear resistance if items shift or corners compress.
