White Poly Mailers 7.5" x 10.5

This pack contains one hundred white poly mailers sized at 7.5 by 10.5 inches. They are designed for businesses, offices and individual sellers who need lightweight, opaque shipping bags for clothing, accessories or small goods. The self-sealing adhesive strip closes quickly without tape. Each pack weighs 1.9 lbs, keeping freight costs low.

Build Quality and Daily Use

The mailers use a durable polyethylene material that stretches up to three times its original length without tearing. A black inner lining makes the bags opaque, so contents stay private during transit. Reinforced edges and a strong self-seal strip resist splitting even when the package is handled roughly. The smooth white exterior accepts handwritten or printed waybills cleanly.

Practical Limits of the Format

The fixed 7.5 by 10.5 inch dimensions limit the size of items that fit inside; bulky or rigid products may need a larger mailer or a box. Polyethylene provides water and dirt resistance but does not offer cushioning, so fragile items require separate padding. The single-use adhesive seal cannot be reopened without damage, making the bags unsuitable for return-friendly packaging.
