Because the laminating equipment does not need adhesive heating and drying system, the laminating process greatly simplifies the laminating process, and the operation is very convenient. It can be used with the booting machine, and has great production flexibility, no solvent smell, no environmental pollution, and more importantly, it can be completely Avoiding bubbles, delamination and other failures, the finished product has extremely high transparency, and has broad application prospects and promotion value.
          The precoating laminator structure consists of a substrate and a glue layer. The substrate is usually PET and BOPP film. From the material cost and processing technology, most precoated film substrates are BOPP film with a thickness of 12-20 microns. The thickness of the glue layer is 5-15 microns. According to different processing equipment and process conditions, different thicknesses of glue layer are selected, and the glue layer is divided into hot melt adhesive and organic polymer low temperature resin. The difference between the two is that the hot melt adhesive is made by blending and modifying several materials of the main adhesive resin, the tackifier and the modifier, and the organic polymer resin is a single polymer low temperature copolymer.
