Abstract
ABSTRACT
A tubular bag blank has a plurality of outer contiguous non-heat sealable plies and an inner heat sealable plastic ply. All of the plies in the tubular blank are bonded together circumferentially around an open top end of the bag and are closed at the bottom end where only the non-heat sealable plies are bonded together. The inner heat sealable ply is freely folded and fully detachable in a non-adhesive manner at the bottom end of the bag.
The inner plastic ply being heat sealable to closure at both bag ends. Upon heat sealing the bottom end, a plastic pouch is formed by the inner ply which may be heat sealed to closure at the open end when filled with a product or commodity and may be optionally severed thereat by compressive heat and pressure applied to the outer non-heat sealable plies. When fully packed, the outer paper plies may be stripped away leaving a sealed plastic pouch with the packaged contents therein ready for use by the purchaser.
