"Environmental, health and safety" is a universal topic, also is the focus of attention industries.Flexible packaging industry is no exception.,especially in recent years, the rapid growth of our packing industry packing and the widespread application, the influence of environmental, health and safety increasingly prominent. Among them, soft compound with adhesive is one of the core problem discussion.
At present, all countries in the world resin actively explore alternative products of two-component polyurethane adhesives coatings.Like no solvents glue, glue, water-borne polyurethane adhesives, soluble polyurethane adhesive environmental adhesives etc,and they have made great progress in some fields.
The development and marketing aspects on environmental protection, all countries have very big difference, the measures for the different also. In Europe, the water polyurethane adhesive and distributed without solvent adhesive research has been walking in front,the Market develop rapidly; In the United States, reactive glue on the fast development. But after printing equipment, so far, no new adhesives can replace solvent two-component polyurethane adhesive. Moreover, from the overall market at present situation, solvent polyurethane adhesive demand continues to increase, and growth than other types of adhesives.
Though our flexible compound with adhesive research started in late , but through years of practice, we have accumulated a certain amount of experience, and cultivate a large number of technical research personnel. Meanwhile, environmentally friendly adhesive in domestic market growth also accelerating, some technical powerful adhesive production enterprises and related technical reserves, and actively developing new products.
In China's current economic environment and market condition, management system, combining the domestic present situation of packing industry, domestic enterprises can produce adhesive agent from the following two aspects, develops the market, seek the development.
1. Develop high solid content adhesive
Using high solid content adhesive in a composite production, while the adhesive concentration mentioned above 40%, to reduce the solvent (mainly ethyl acetate, and reduce vocs) pollution to the environment.
At the same time, there are many adhesive production enterprise has a high solid content adhesive. Like Beijing union launched YH2880 and YH2985 before printing adhesive technology, solid content for 80% and 85% respectively; Hankel company launched a solid content for 80% of the UK2880, can work in more than 40% of the concentration of high-speed coating,and flexible production enterprise doesn’t need to do big adjustments to composite equipment, just use different number nets of applicator roll.
2. Develop water-borne glue stick and resin adhesives authentication
