Performance and Process of Waterborne Adhesive for Printing and Packaging

With the gradual improvement of national living standards, people on the printing and packaging of exquisite, green and other requirements are getting higher and higher, thus driving the printing and packaging industry to flourish, but also led to a large number of productions about adhesive which is used for printing. One of the water-based adhesive with its water-based environmental protection, excellent performance and come to the for 

Printing water-based adhesives mainly include water-based laminating adhesive, water-based sealing adhesive, starch glue, paper paste and other varieties.

1.water-based laminating glue
Water-based laminating adhesive with high brightness, low cost, easy operation, water-based environmental protection features. In recent years has been a large number of popular. Water-based laminates are mainly cold-paste compound and dry-type compound two. The market is mainly based on cold paste compound, but the dry compound development faster and faster. Water-based cold paste laminating machine covers an area of less space, less power consumption, easy to operate. Water-based dry laminating adhesive with a strong ability to cover the powder, finished high stiffness, strong bonding properties, it is good for ink compatibility.

2.  water-based sealant

Binding has been unable to meet people's aesthetic needs of the packaging, so the use of adhesive on the seal of the seal has become a good choice. Because of its water-based environmental protection, flexible film, anti-aging performance and other characteristics，water-based sealing adhesive to become the mainstream of the market. Water-based sealing adhesive is a kind of milky white to yellowish viscous liquid. By the different manufacturers of water-based sealing adhesive in the opening hours, the initial viscosity, durability, odor appearance will be a greater difference.  Selection, it should be fully tested its adhesive products to do low temperature resistance, durability, peel strength for adequate testing, and try to use large output, high quality control of the manufacturers.

3. mounted tile with rubber powder or starch glue
Due to the greater alkalinity, and the adhesive force in general, the choice of starch modified with powder or direct finished starch gel will be a suitable choice. Selection of powder should be selected when the appropriate formula, and should pay attention to shelf life.

4. Flattened and mounted paste 

It is suitable for the combination of cardboard and cardboard, and the market generally has PVA acetal and modified white plastic two.
