Supplied in a bulk pack of 1000 pieces, the product is economical for frequent mailers and reduces the need for frequent reordering. The construction is suitable for mailing documents, brochures and small printed materials securely.

How to use

Insert documents or printed materials into the envelope ensuring they fit within the 240×165 mm opening and account for the 15 mm gusset when enclosing multiple items. Remove the protective strip from the peel-and-seal adhesive and press the flap firmly along the adhesive line to close. For heavier contents, press along the entire length of the seal and ensure the gusset is folded neatly to reduce strain on the closure during transit. Store unopened packs in a dry, flat location to maintain adhesive performance.

Recommendations

For reliable delivery and presentation, use these envelopes for folded A4 documents, multi-page invoices, or sets of brochures. When mailing heavier contents, combine with appropriate postage and handling services; avoid overstuffing beyond the 15 mm gusset capacity to prevent seal failure.
