Abstract (en)

A heat sealable mailer form is provided comprising a sheet (10) which includes on at least one of its major surfaces a pattern of adhesive (16) which is not activated by the heat and pressure rolls of a non-impact printer but which is activated by the application of additional heat and pressure after printing of the sheet. The adhesive (16) comprises a thermoplastic adhesive and a filler and is preferably coated on the peripheral edges of the sheet. The sheet (10) is folded and sealed by the application of heat and pressure to the adhesive covered areas of the sheet.
