Material and material of the pre-coating film laminator: The pre-coating film structure is composed of a base material and an adhesive layer. The base material is usually PET and BOPP film. From the perspective of material cost and processing technology, most pre-coating film substrates use BOPP The thickness of the film is 12-20 microns, and the thickness of the adhesive layer is 5-15 microns. According to different processing equipment and process conditions, different thicknesses of adhesive layer are selected. The adhesive layer is divided into hot melt adhesive and organic polymer low temperature resin. The difference between the two is that hot-melt adhesives are made by blending and modifying several materials such as main tackifier resin, tackifier and modifier, while the organic polymer resin is a single polymer low-temperature copolymer.

        The prospect of pre-coating film laminating machine: this process does not require adhesive heating and drying system, which greatly simplifies the filming process, and the operation is very convenient. It can be turned on at any time, and the production flexibility is large, and there is no solvent odor. There is no environmental pollution, and more importantly, it can completely avoid bubbles, delamination and other failures. Its finished products have extremely high transparency and have broad application prospects and promotion value.
