Heat-seal mailers feature a thermoplastic adhesive strip that bonds permanently when heated, creating a tamper-evident, secure closure. They're ideal for high-value items or brands requiring enhanced security compared to traditional peel-and-seal.

The 3/16" bubble lining offers adequate cushioning for lightweight fragile items like electronics, cosmetics, and jewelry during standard parcel handling. For heavier items or extreme fragility, consider pairing with additional void fill.
