Here we will talk about extrusion, wich is the process when we take the raw material of polyethylene that comes in shapes of pellets and it is a product from the petrochemichal industry. Once feeded into the machine the screw inside it will melt the pellets and make an uniform paste.

At the end of the screw we have a circular dye the blows the hot material up creating the polyethylene film each time according to the demands and specifications of the customer, This film could be a tube, centerfold, open in bode sides or a sheet . We also adjust the machine so we can get the thickness of the film according to every order.
