E-Commerce Cold Seals

Self-sealing corrugated mailers ("cold seals") are fibre-based packaging solutions designed for secure and efficient e-commerce shipping. Manufactured from single-face corrugated cardboard with an integrated self-adhesive coating, these mailers combine protective cushioning and secure closure in one streamlined format.

Engineered to fit specific product dimensions, self-sealing corrugated mailers reduce the need for additional outer cartons, void fill or plastic padding — making them ideal for online retail and direct-to-consumer fulfilment.

What It Is

Self-sealing corrugated mailers are wrap-style corrugated packaging formats featuring a built-in adhesive strip for quick and secure closure. The integrated adhesive eliminates the need for separate tape, improving packing speed and reducing material complexity.

Designed around the product, these mailers provide a snug, protective fit while minimising excess material usage. E-Seal is our branded self-sealing corrugated mailer solution developed specifically for e-commerce applications.
