This style of sack is ideal for confidential waste as the whole sack and its paper contents can be shredded or pulped without having to open the sack. They are also popular for mail order use where there is a requirement for a tamper evident seal.
Paper sacks manufactured flat or gusseted with a stepped top (lip) featuring a pressure sensitive glue and peel tape. On removing the peel tape the lip can be folded down to glue and seal the package. The tamper evident glue will tear the paper when the sack is opened. The strong stepped and pinched closed bottom provides a neat flat paper sack that blocks well when filled. Constructed from 1 to 3 plies of 70 to 110 gsm paper and available printed or unprinted as desired.
