Setup, Compatibility & Care
To ensure optimal performance, verify that the dimensions of your items are comfortably within the 290 x 445mm envelope size. Before sealing, press the self-seal strip firmly across the entire width of the flap to activate the adhesive completely.
Store these mailers in a cool, dry environment away from direct sunlight to maintain the integrity of the adhesive and the paper fibers. The mailers are designed for single-use; ensure all contents are secure before final sealing as the adhesive bond is designed to be permanent and tamper-evident.
