Abstract
Disclosed are bags especially adapted to be made from plastic material and in which the bag body film or material and extruded plastic zippers are fusibly incompatible. A pair of extruded plastic zipper strips having reclosable zipper profiles facing toward one another along the lower sides of pull flanges of the bag have the opposite ends of the strips sandwiching opposite side seal seams of the bag therebetween. The opposite side seal seams have holes therethrough, and fused connecting anchors formed from the material of the zipper strip ends extend through the holes. The bag may be closed by squeezing the zipper strips together so that the profiles interlock with one another and interlock the intervening area of the bag walls therebetween. A method of making the bags is also disclosed.
