"DELI" BAG WITH EXTRA THIN WALLS AND INCREASED STRENGTH AND METHOD OF MANUFACTURING SAME
“Deli” bags are formed by extruding first and second aligned sheets of high density polyethylene film having a thickness no greater than 0.0008 inches. The aligned sheets are heat sealed along the sides and either the top or bottom edges to form each bag. After printing indicia on the wall of each bag, mating closure tracks are created. The tracks are situated proximate the non-sealed top or bottom of the bag. A closure member in the form of a slide or zipper is installed as the bags are separated and stacked. The closure member co-operates with the closure tracks to open and close the bag. Preferably, four side-by-side bags can be processed at the same time, increasing efficiency and reducing manufacturing cost. The bags have extra thin walls, increased strength and keep food fresher.
1 . A plastic deli bag comprising first and second aligned sheets of high density polyethylene film sealed along the sides and either the top or bottom edges having mating closure tracks proximate the non-sealed top or bottom edge thereof and a closure member co-operating with the closure tracks to permit the bag to be opened and closed.
2 . The bag of claim 1 wherein said closure member is a slide member.
3 . The bag of claim 1 wherein said closure member is a zipper member.
4 . A plastic deli bag comprising first and second aligned plastic sheets having a thickness of no more than 0.0008 inch heat sealed along the sides and either the top or bottom edges having mating closure tracks proximate the non-sealed top or bottom edge thereof and a closure member co-operating with the closure tracks to permit the bag to be opened and closed.
5 . The bag of claim 4 wherein said closure member is a slide member.
