Paper packaging is divided into two categories, one is pure paper packaging, such as corrugated boxes, paper drums, cartons and paper bags which is currently the largest widest used packaging. The other is paper-based composite material packaging, such as paper / plastic composite box (bag), paper / aluminum foil composite box (bag), paper / wood composite material box (box). 1. Adhesive for plain paper This kind of packaging with more adhesive is starch gel and polymer emulsion. 2. Paper - based adhesive for composite materials As long as the molecular structure design of Acrylic Emulsion Modified Composite Adhesive is reasonable, can overcome all of its shortcomings while having the advantages of VAE emulsion modified adhesives .Peel fastness is very good, the cost is also significantly reduced. Not only can paper / BOPP, but also composite paper / PET, paper / PVC, paper / aluminum foil, paper / paper, and has formed a large-scale production and sales. 3. The development direction of adhesive for paper packaging High solid content of water-based emulsion glue, water-based and solvent-free polyurethane adhesive, biodegradable hot melt adhesive, green multi-functional composite rubber is the future development trend of green paper and plastic adhesives.

Introduction: Water-based adhesives to water as a dispersion medium adhesive, is a major category of environmentally friendly adhesives. The solvent-based adhesive is a homogeneous system with organic solvents such as benzene and toluene as the dispersion medium. The water-based adhesive is a heterogeneous system with water as the dispersion medium. Classification: Water as a dispersion medium adhesive is divided into water-soluble adhesive, water-based adhesive and water-based adhesive. Water-based adhesives are mainly divided into water-based polyurethane adhesives, water-based polyacrylate adhesives, water-based epoxy adhesives, water-based silicone adhesives, polyvinyl acetate emulsion,chloroprene latex. Water-based adhesives mainly include phenolic, urea-formaldehyde, melamine formaldehyde, polyvinyl acetate emulsion, EVA emulsion, polyacrylate emulsion, water-based polyurethane, and water-emulsion epoxy, the latter in the domestic stage. Advantages and disadvantages: Water-based adhesive is one of the development trend of adhesives, compared with solvent-based glue, has advantages of solvent-free release, in line with environmental requirements, low cost, non-combustible, the use of security and so on. Its solid content is relatively high, up to 50% to 60%. But because of the slow evaporation of water, the curing slow or need to heat drying equipment. Many government departments issued a decree to limit the use of volatile organic compounds (VOCs), adhesives from the solvent to the water-based type of transformation has become inevitable at home and abroad are vigorously research and development.

Polymeric materials are made from high temperature reaction polymerization of water-based plastic film, the product is the ideal composite adhesive of printing color printing industry , widely used in paper and plastic film, paper and paper composite, non-polar material or weak polarity. It has a high bonding strength, weather resistance and excellent water resistance, free of formaldehyde, benzene. 1.  Product Features a. Good early sticky b. Good water & weather resistant c. High bond strength 2. Product Usage Widely used in oil paper, polishing paper, copper paper, white paper and other materials between the composite and the corresponding composite material of printing color printing packaging industry.

Water-based pressure-sensitive adhesive and its products (all kinds of pressure-sensitive adhesive tape, pressure-sensitive labels and pressure-sensitive adhesive sheet, etc.) in recent 20 years in China has been rapid development. China's production and sales of various water-based pressure-sensitive adhesive products in mainland China in 2015 and the annual sales volume and sales after the United States ranked second in the world. Water-based pressure-sensitive adhesive and its products have been applied throughout all areas of the national economy, and has entered thousands of households. However, in the application of water-based pressure-sensitive adhesive products basic research and technology development, China is still a gap with developed countries. Some high-performance water-based pressure-sensitive adhesive products and high-tech special products still rely on imports from developed countries. Especially the lack of high-quality technical personnel and management personnel and the weak research and technology development team (especially in the enterprise), and water-based pressure-sensitive adhesive products is booming situation is not suited to, but also restricts the water-based pressure-sensitive adhesive product industry continues to develop.
