One,Overview
Paper-plastic composite can make the surface of paper printed matter more bright, smooth and color more bright and full of three-dimensional sense, but also play a role in moisture, anti-fouling, anti-counterfeiting, folding resistance, wear resistance and so on.It has been widely used and rapidly developed in printing and packaging industry at home and abroad. The market demand for paper plastic laminating adhesive is increasing day by day, the market is mature, and the potential is huge. Traditional paper and plastic film adhesives are mainly solvent-based film adhesives, but a large amount of solvent volatilization pollutes the environment in the process of use, and flammable and explosive storage and transportation is inconvenient, the use of large energy consumption, the use of high cost.According to the characteristics of paper-plastic composite, the use of water-based cold-paste paper-plastic composite film adhesive, non-toxic and pollution-free, low cost and no fire hazards, and has the characteristics of good brightness, no bubbles, no yellow, especially with the increasing awareness of people's environmental protection and the mandatory implementation of relevant national environmental protection policies, the development of paper-plastic composite adhesive to water-based is an inevitable trend.Paper-plastic cold-paste water-based film adhesive is also called cold-paste adhesive, cold-paste adhesive, water-based cold-paste film adhesive, etc. At present, the domestic packaging and printing industries have gradually begun to use water-based film adhesive to meet the requirements of environmental protection, and the market demand is expanding. Therefore, the production of water-based cold-paste paper plastic film adhesive is not only a mature market, easy to develop, but also has a stable and mature development prospects, social benefits and economic benefits are obvious.
Second, product characteristics and application range
1.this product is suitable for bidirectional tensile polypropylene film (BOPP) polyvinegar (PET) film and a variety of color printing paper composite, can be used for old film machine, can also be used for new film machine.
2.environmentally friendly products, water-based non-toxic, non-polluting, non-combustible and non-explosive. Good brightness, no bubbles, no glue.
3.Low energy consumption, easy to use cold paste, low cost. There is no need to heat the drying channel or the composite roller when the film is laminated, and the energy saving effect is obvious
4.the use of new technology to produce products with stable quality, low cost, strong ability to eat powder, solid content of 16%~42% of the whole series of products can cover powder, consistency is easy to adjust, uniform glue, glue stability, good permeability and ink
Third, product quality indicators

1.Appearance: milky white viscous liquid
2.Product performance conforms to the following table:

Project	Index
Solid content	18~42
pH	4~7
Viscosity mPa.s	800~4000
