Semi Automatic Plastic Bag Making Machine

An extruder is used to heat the polyethylene plastic to a temperature of about 500 degrees F. This temperature will melt the pellets, at which time the molten plastic is pushed into the machine and a die that determines the thickness that the bag will have.Bag making machines come in various configurations based on the bag types produced by the machine. The bag making machine produces a bag by passing a roll of plastic film through a series of operations like heat sealing, cutting, combing. The film is typically flexible, heat sealable plastic.
