With the continuous enhancement of human awareness of environmental protection, environmental laws and regulations are constantly introduced and improved all industries are working together in the direction of environmental protection, green and health.With the development of flexible packaging industry, it has become an inevitable trend to reduce and remove organic solvents used in compounding.Water-based composite adhesive in the use of methods and price technology is gradually mature, become the new darling of the soft bag industry, has achieved rapid development inside and outside. In the plastic composite and plastic aluminum composite, mainly with water-based polyurethane and water-based acrylic polymer water-based adhesive mainly has the following advantages. the composite strength of water-based adhesive molecular weight is large, is dozens of times of polyurethane adhesive, its adhesion is mainly by van der Waals force, belongs to physical adsorption, so a small amount of glue can achieve quite high composite strength soft, more suitable for aluminum film composite One-component softer than the two-component polyurethane adhesive, water-based adhesive when they completely after solidification, very rigid polyurethane adhesive, water-based adhesive is very soft So soft properties of water-based adhesive and composite elastic is more suitable for aluminized film, not easily lead to aluminum plating film transfer. do not need to cure, cutting and after off the plane.Single component water-based adhesive compound does not need to be cooked, after the machine can be cut bag and other subsequent processes.This is due to the initial adhesive strength of water-based adhesive, especially the high shear strength, to ensure that the product will not produce tunnel folds and other problems in the process of composite and cutting.Moreover, the strength of the film composite with water-based adhesive can improve by 50% after 4 hours. Here is not the concept of curing, the colloid itself does not occur cross-linking, mainly with the leveling of the glue, the composite strength also improves. rubber thin, good transparency Less as a result of water-based adhesive glue, and glue concentration higher than that of solvent adhesive, so need drying and discharge water also far less than water completely after drying, solvent adhesive film will become very transparent, due to the sub is thinner, so the transparency of composite is also better than solvent-based adhesive environmental protection, harmless to people.There is no residual solvent after drying of water-based adhesive. Many manufacturers use water-based adhesive to avoid residual solvent brought by composite, so the use of water-based adhesive production is safe, and there is no damage to the health of operating staff. With the increasing application of composite flexible packaging materials, water-based composite adhesive is not only used in the packaging of food and drugs, but also used in the pa...

Water-based ink resin is suitable for intaglio printing ink. The ink coating prepared with this product has good film forming ability, quick drying, high gloss, high hardness and scratch resistance, good film forming ability on the surface of paper foil and good compatibility with water-based pigment. Application characteristics 1 Good film formation 2 Suitable for a variety of substrates, good adhesion 3 fast drying speed, no peculiar smell after the ink layer film 4 good wettability of pigment, good leveling 5 good resolubility, good fatigue resistance, long-term printing without blocking and stable ink performance In order to ensure the quality of water-based ink resin products, the products should be placed in the shade, avoid heat and humidity, and keep the packaging sealed after each use to avoid pollution.

From the development of printing industry in developed areas of the future development track can be considered in China's packaging and printing industry to take the road of environmental protection is an inevitable trend, and the environmental protection of ink plays an increasingly important role.Although the stage has not yet established green ink or environmental protection ink discrimination standards, but the industry view is: those in the production and packaging and printing process less pollution, the health of human production and life and natural environment almost does not cause harm to the type of ink, it contains the following aspects of meaning. 1 significantly reduce the harmful components in the ink 2 significantly reduce the ink production and use of the process of the harm to the operator and the natural environment 3 It is beneficial to the recovery, treatment and reuse of packaging waste In accordance with the above standards, in line with the development of China's flexible packaging printing industry, at this stage in the market environmental protection ink is mainly the following many types: no benzene alcohol-soluble ink polyurethane ink water-based ink (acrylic acid system) UV light curing ink soybean ink single solvent ink. No benzene alcohol soluble ink: connection material for alcohol soluble polyamide resin, does not contain toluene, but contains a small amount of ketone solvents, more suitable for to be boiled flexible packaging printing, generally only for benzene soluble substitute plastic gravure table printing ink This kind of ink is no benzene packaging printing industry boom in the early launch of ordinary alcohol soluble plastic gravure printing ink. Acrylic water-based ink: big advantage is that do not contain volatile organic solvents, the natural environment no pollution, no damage to the ink maker and packaging printing operation technical personnel health, the deficiencies are ink film with poor gloss, packaging and printing drying speed is slow, packaging printing eligibility weaker, integrated the above a few factors, couldn't completely replace soluble acrylic type of water-based ink Agent ink. UV light curing ink :UV ink coating, UV light irradiation can be quickly dry curing, and the hardness of the ink layer is higher than other types of ink, with high environmental protection and energy saving solid content The advantages of low VOC content in high-speed inkjet printing and plate printing industry has great advantages, but in the flexible packaging gravure printing industry, compared with solvent ink,UV ink still has many deficiencies:First is UV ink price is relatively high, UV printing production line of the input is large, the demand is relatively harsh natural environment condition printing production workshop, this is also the UV printing ink is very difficult to mass in different packaging and printing industry to implement a major factors: second, UV ink in many printing substrate adhesion ...

Water-based plastic composite ink is a product with water as the solvent. From the perspective of printing mode, water-based ink is not suitable for offset printing at present. Its main application fields are flexographic printing gravure printing and screen printing. Printing costs are related to the raw materials selected by ink manufacturers, such as the size of the molecular weight of the resin formula production process, the addition of solvent in the printing process in addition to the closed printing workshop, the rest will change due to the temperature and wind and other factors. Water-based plastic composite ink to add diluent only as a reduction in the viscosity of the ink, so that it is suitable for printing, such as excessive adding, ink color concentration will be reduced, the amount of connecting material is reduced at the same time, so that it can not print a good product. Therefore, water-based ink only pure water, and is a one-time addition (pre-press) In the printing process, it will not cause color changes because of the change in viscosity, but not like ink, because of the waste generated when diluent needs to be added to the printing process, which greatly improves the qualified rate of printing products, saves the cost of solvent, reduce the emergence of waste this is one of the cost advantages of water-based ink.
