Setup, Compatibility & Care
To ensure the best results, insert your documents carefully to prevent corner snags on the gusset. When sealing, apply firm, even pressure across the entire length of the flap to activate the Power-Tac adhesive. Store these envelopes in a cool, dry place to ensure the adhesive strip maintains its shelf life and bond strength. These envelopes are compatible with standard postal regulations for C4 sized packaging; always verify the thickness with your local post office if the final package exceeds 25mm in total depth.
