Currently, one of the most common packaging material is polyethylene, more specifically plastic bags. Actress: the source for more info. For the manufacture of polyethylene bags for welding neck of such a package filled with product or piece goods, used welding machines (also known as yet and equipment for welding the film). In such facilities for welding and welding of plastic film package, use the pulse heating. This welding technique of the film low-power, as pulse time (the time for which is welded plastic film) is in the range of 1 to 10 seconds. Time depends on the length of the weld and the thickness of the film. Typically, the momentum welding machines operate in two modes: 1.
Manufacture of plastic bags from a roll of plastic film and simultaneously it by cutting from the roll (welding wire). 2. Welding neck of a plastic bag or manufacture of plastic bags from a roll of plastic film with further cutting off from the roll with a knife, supplied the welding machine (welding tape). Such equipment for welding of the film is floor and table. Typically, a desktop welding machines are not the great length of the weld (500 mm), while the outdoor machines weld length can reach several meters.
