Polypropylene wrap end seals and process for making same

摘要

A voided polypropylene film tampon wrap having end seals which are formed by mechanical crimping and a process for sealing the ends of the voided polypropylene film tampon wrap by mechanical crimping. A notch is formed adjacent to each end seal but remote from the enclosed tampon. Each end seal is formed by a pair of horizontal teeth wheels each having a pitch of 50 teeth per inch. One of the pair of wheels is heated to a temperature of 125 DEG +/-15 DEG , and force is applied to at least one wheel to seal that end of the wrap by the pair of wheels.
