Common questions
Do these mailers require tape, glue, or a sealing machine?
No. The peel-and-seal closure is built-in and ready to use. Simply peel the release strip and press to seal, no additional equipment, tape, or adhesives needed. This saves time in fulfillment and reduces labor costs.
Will these mailers protect documents and photos from bending or creasing?
Yes. The.028 kraft chipboard provides puncture and bend resistance, while the rigid construction prevents warping during transit. Products arrive in professional condition, reducing damage-related returns and customer complaints.
How much do these mailers weigh per unit, and will they increase postage costs?
These lightweight mailers weigh approximately 0.3 oz each, minimizing dimensional weight charges. Unlike bubble mailers or padded envelopes, you save on postage without sacrificing protection, ideal for high-volume shippers seeking margin improvement.
Are these mailers eco-friendly?
Yes. Kraft chipboard is 100% recyclable and made from sustainable materials, aligning with environmentally conscious brand values and reducing your carbon footprint per shipment.
