According to statistics, by 2020, the global market value of adhesives and plasticizers will reach 43.195.5 billion U.S. dollars. During this period, the main driving force of the adhesives and plasticizers market comes from the construction, automobile and packaging of China, India and Brazil. The development of the market.

Water-based adhesives use high-molecular polymers, water-soluble resins, etc. as the main raw materials, water as the solvent, low odor, environmental protection and non-toxic. With the continuous improvement of people's awareness of environmental protection, water-based adhesives have become the mainstream of the market in recent years. In practical applications, some packaging and printing companies lack sufficient knowledge of water-based adhesives, which causes some quality problems. Among them, the problem of "difficult bonding" of water-based adhesives is one of the technical bottlenecks that plague many packaging and printing companies. In order to let more packaging and printing companies understand water-based adhesives, the author will elaborate on the characteristics and selection of water-based adhesives, hoping to give the industry some inspiration.

(1) The viscosity of the adhesive is insufficient or the amount of glue applied is insufficient.
(2) The adhesive does not match the material of the carton.
(3) The sticking part of the carton has been surface-processed such as laminating, glazing, etc. It is difficult for the adhesive to penetrate the surface and penetrate into the paper, making the carton difficult to stick firmly.
(4) The pressure is not enough after folding and gluing, and the pressure time is not long enough, which is not conducive to sticking firm.

Many traces can be wiped off with an eraser, and marks like transparent glue can also be wiped off. Try to rub it slowly, and rub it repeatedly to get it off. It should be noted that, basically, the easily faded part of the color may also be rubbed off, so be careful when using it.

Adhesives used in the aluminum foil packaging of medicines must have good safety and sanitation properties, no peculiar smell and non-toxic. If the medicines directly contact the adhesives, they should also be non-corrosive. Because the products protected or packaged by the aluminum foil packaging materials for pharmaceuticals are directly imported, not only the base material must be tasteless, odorless, and non-toxic, but also the adhesives used must have the same performance. Therefore, the raw materials, auxiliary materials and solvents for the production of adhesives should have Safety and hygiene.

Jelly glue is jelly glue, and its scope of application: it is used for the pasting of all kinds of high-end hardcover books, photo albums, and gift boxes. This glue has a fragrant smell, strong viscosity, good fluidity, clean use effect, strong foldability, and fast drying time; it can solve the deformation, brittleness, and blistering that are easy to produce after the book case is made, and it will not corrode the machine. effect. JELLYGLUE translated in Chinese is jelly

The container containing the pasting glue must be tightly closed to prevent the surface of the pasting glue from drying out and being contaminated. It should be stored in a ventilated and dry warehouse, protected from direct sunlight, transported and stored at a temperature above 5°C, and the validity period is half a year.

The flow rate MFR of PP plastic products ranges from 1 to 40. PP materials with low MFR have better impact resistance but lower elongation strength. For materials with the same MFR, the strength of the copolymer type is higher than that of the homopolymer type. Due to crystallization, the shrinkage rate of PP plastic products is quite high, generally 1.8~2.5%. And the direction uniformity of shrinkage is much better than that of PE-HD and other materials. Adding 30% of glass additives can reduce the shrinkage to 0.7%.

According to the "China Fund News" report, last week the Fund conducted intensive research on 61 listed companies, and 7 listed companies were "grouped" by more than 5 funds. Companies in the rubber and plastic products industry have received greater attention.

1. This product can be used directly, in order to improve the fastness and washing resistance, you can add 3-5% of the special curing agent, stir and use it evenly.
2. This product is suitable for roller coating, knife coating, etc. If the sponge adheres to the cloth, the rubberized surface is sponge. The amount of glue applied is 25-40g/M², which can be adjusted according to the requirements of different fabrics.
