Description

Technical Field

[0002] At present, many polymer film packaging materials are mainly processed by laminating technology to make the packaging materials have barrier and heat-sealing properties. Existing polymer film packaging materials need to be sealed with glue during packaging. After sealing, the packaging bags are prone to loose adhesion and easy peeling. At the same time, the gluing process requires additional equipment, and the debugging and coordination of the automated production line is also quite troublesome. In particular, watering as a chemical product preparation will pollute the environment, which is particularly prominent in the outer packaging of medical supplies.

[0038] Embodiment 2:

[0039] like Figure 1-8 In the present invention, the method of use is as follows:

[0045] Step 6: After the trimming is completed, the material is rolled up by the receiving roller 12, and the whole roll of material is unloaded after processing is completed.
