Pre-coated film: the adhesive is pre-coated on the plastic film, after drying and winding, there is no hot-pressing on the laminating equipment without adhesive coating device. Its characteristic is that it does not require an adhesive heating and drying system, which greatly simplifies the laminating process, is convenient to operate, can be used at any time, has great production flexibility, tasteless, solvent-free, does not pollute the environment, and more importantly avoids bubbles, The occurrence of film barriers such as delamination and high transparency of the product.
        It can provide high-quality products for the pre-coating process, which significantly improves the smoothness, clarity and vividness of the printed and packaged products after lamination. It is safe and hygienic, eliminating the health hazards to producers and consumers, and eliminating hidden fire hazards. Defects, with strong powder-eating ability, improved film coating speed, short downtime, low waste rate, easy operation of the film coating process, labor saving and relatively cheap, etc.

        The commonly used film materials for domestic pre-coated films are polyvinyl chloride (PVC), polypropylene (BOPP), polycarbonate and polyester (PET) films. Among them, BOPP film (15-20) is flexible, non-toxic, high in transparency, and cheap in price. It is an ideal composite material in the laminating process. There are three varieties of bright, matt and matt.
