Common questions
Will these mailers protect photos and documents from bending?
Yes. The.028 chipboard construction provides rigid, bend-resistant protection that keeps photos and documents flat throughout shipping. The Stayflats Plus® design eliminates the need for additional stiffener boards, reducing material costs while maintaining professional presentation.
How much does this reduce shipping costs compared to heavier mailers?
Kraft chipboard mailers are significantly lighter than padded or corrugated alternatives, lowering dimensional weight charges and postage fees. For e-commerce brands shipping high volumes, switching to these lightweight mailers can reduce per-unit shipping costs by 15-25% depending on carrier and zone.
Is the peel-and-seal closure reliable for transit?
Absolutely. The integrated peel-and-seal adhesive closure is engineered for secure, tamper-evident sealing. No additional tape, glue, or equipment is required, simply peel, align, and press for a professional, customer-friendly seal that lasts through shipping and handling.
Can customers easily open these mailers?
Yes. The pull-tab tear strip is designed for intuitive, damage-free opening. Customers simply locate and pull the tear strip to reveal contents without risking product damage or requiring scissors, enhancing unboxing experience and reducing return friction.
