China Professional BOPP Thermal Lamination Film manufacturer

BOPP thermal lamination film has the characteristics of high transparency, good brightness, non-toxic and tasteless, water resistance, heat resistance, low price, soft texture, etc. It is the ideal material for laminating process, and its thickness is about 12-20um. Therefore, from the perspective of material cost and processing technology, most of the pre-coated film substrates use BOPP film.
The adhesive layer of pre-coated film has two types: melt type and solvent volatile type, and according to the different processing equipment and process conditions, different thicknesses of adhesive layer are used. The adhesive layer of domestic pre-coated film is mainly composed of hot melt adhesive or organic polymer low temperature resin. Hot melt adhesive is modified by the main adhesive resin and several kinds of materials such as adhesion enhancers and conditioning agents. Organic polymer resin is a single polymer low-temperature copolymer. Since the hot melt adhesive is a mixture of several materials, the transparency of the laminated film is significantly lower than that of the low temperature pure resin-based pre-coated film.
