How Polyethylene Bags are Made

Polyethylene Bags are made by heat sealing and cutting rolls of film. Rolls of tubing or sheeting are fed through a machine that draws material out to the proper length. The machine then cycles to place a seal on the material and then cut it off to make an individual bag. In some cases, with small bags, machine cycle speeds may produce up to 70,000 bags per hour. In other instances, a large bag may run as slowly as 2,000 bags per hour.

Using up-to-date manufacturing technology, A-Pac's modern machines employ servo drive motors for optimal control and accuracy.

Sideweld Poly Bags

Sideweld Poly Bags are made using centerfolded film, welding and cutting to produce seals on the side of the bag. When we produce sideweld bags, we test to make sure that the seal is at least as strong as the base material. A properly made sideweld bag will not split or zipper tear along the seal. Sizes can range from 2 x 3 to 52 x 52.

Bottom Sealed Poly Bags

Bottom Sealed Poly Bags are made using poly tubing material and applying a seam to one end of the material. Bottom seal construction is commonly used for side gusseted bags and bags thicker than .004. Sizes range from 4 x 8 to 50 x 120.
