• Courier Envelopes & Self-Sealing Boxes

    Cardboard envelopes and boxes with adhesive strips

    The ultimate unboxing experience for e-commerce. Gammapack Bulgaria manufactures specialized shipping solutions designed for speed and security. We produce cardboard envelopes and corrugated boxes equipped with pre-applied silicone adhesive tape (Peel & Seal) on the flaps.

    This technology speeds up your packing process by eliminating the need for packing tape. Additionally, we can integrate a Red Tear-Strip (Zipper) for easy, frustration-free opening by the end customer. All products are fully customizable with offset or flexo printing.
