An important link in the production of color printing packaging is after color printing or paper-plastic film decoration, now the means of packaging products mainly rely on film or glazing, advertising instructions, books and notebook covers, commodity packaging and signs are all so.

In terms of surface coating or glazing, there are now a variety of decorative methods to choose from, such as:

(1)Cover BOPP, PE or PVC plastic film with water-based laminating glue;

(2)With organic solvent-based coated plastic film;

(3)Cover the plastic film with a plastic film pre-coated with adhesive;

(4)Select the high-grade coated paper that has been coated with finishing agent directly, and no longer polish or laminate after printing;

(5)After printing, the surface is coated with water-based polishing oil;

(6)The surface is coated with organic solvent-based polishing oil;

(7)With UV UV curing glazing oil and so on.

Correct understanding of the advantages and disadvantages of these surface decoration methods, how their respective vitality, how the future development trend, not only for the packaging and printing industry is extremely important, the development and production of related adhesives, glazing oil, finishing agent, plastic film, laminating and glazing machinery and equipment manufacturers are also extremely important.

First of all, let's talk about the performance and use characteristics of water-based film adhesive, it is a white emulsion adhesive composed of water as a dispersing agent and high molecular polymer as a dispersing phase. The real water-based film adhesive should not contain any organic solvent, the residual organic monomer should be less than 0.1%, and it smells no odor or slightly alcohol or ester fragrance. Good water-based coating adhesive can be used for water-based machine, can also be used for oil machine, water machine structure is simple, cheap (2.5 ~ 100,000 yuan/set), driving speed, is generally 2 times the speed of oil machine. Good water-based adhesive content is about 1 times higher than oil-based adhesive, and it is wet coated, and the adhesive is dry and transparent by the absorption and distribution of water by the paper fiber after coating, and firmly bonded with the plastic film.

The product gloss and whiteness of water-based adhesive are better than that of organic solvent-based adhesive, and the adhesive force is equivalent to solvent-based adhesive. And water-based adhesive with water-based machine coating using cold bonding method, without heating drying, can save a lot of energy; Due to the high content of water-based adhesive, the coating area of water-based adhesive of the same weight is more than 50% larger than that of solvent adhesive, so the product cost of water-based adhesive coating is much lower than that of solvent adhesive; Because water-based adhesive does not contain toxic, flammable, explosive, environmental pollution of organic solvents, but also reduce the risk of fire, because water-based adhesive has so many advantages, so that it has been rapid development in recent years, gradually become the main theme of the market product.
