Common questions
Are these mailers suitable for moisture-sensitive products?
Yes. The 2.5 mil polyethylene construction and self-sealing closure provide water and moisture resistance, protecting contents from humidity, rain, and ground exposure during transit. However, for extremely sensitive items, consider adding internal desiccant packets for enhanced protection.
Will the red color fade or transfer to products?
No. The polyethylene material is colorfast and the dyes are fully bonded to the plastic. The silver inner lining keeps contents completely separate from the colored exterior, preventing any color transfer or staining.
Can I print labels and barcodes directly on these mailers?
Absolutely. The outer red surface accepts labels, stamps, and ink adhesion excellently. The textured polyethylene provides grip for thermal transfer labels, ensuring barcodes remain readable throughout the shipping process.
How much weight can these mailers hold before the seals fail?
These mailers are designed for parcels up to approximately 2-3 pounds with confident seal integrity. The high-strength seams maintain durability even when slightly over-packed, though exact weight capacity depends on contents distribution and density.
