Description
Technical Field
[0001] This utility model relates to the technical field of PE heat shrink film punching device, and in particular to a PE heat shrink film punching device. Background Technology
[0002] PE shrink film is an industrial packaging film product characterized by high tensile strength, high elongation, good self-adhesion, and high transparency. It can be used for both manual and machine wrapping and is widely applicable for the centralized packaging of various goods. PE shrink film is mainly produced by extruding a mixture of several different grades of polypropylene resin. It features puncture resistance, high strength, and high performance. It is used to wrap goods stacked on pallets, making the packaging more stable and neat, and providing superior waterproofing. It is widely used in foreign trade exports, papermaking, hardware, plastics and chemicals, building materials, food, and pharmaceutical industries. After production, PE film is trimmed before use.
[0003] Shrink film is usually perforated according to customer requirements before use. However, a typical perforation device can only perforate once at a time. If it is necessary to perforate both sides of the film continuously, the device will not be very efficient.
[0004] Therefore, we propose a PE heat shrink film perforation device to solve this problem. Utility Model Content
