Reasons for the development trend of environmental protection of flexible packaging polyurethane laminating adhesive

Environmental protection has been the core development direction of flexible packaging polyurethane laminating adhesive, which is promoted by multiple factors such as policy, market, safety and industry upgrading.

 

With the tightening of environmental protection laws and regulations in packaging industry, VOC emissions, harmful solvent residues and heavy metal indicators are strictly controlled. Traditional solvent-based Polyurethane Adhesive has a strong smell and heavy pollution, and it is easy to produce waste gas and waste materials in production and use, which does not meet the requirements of sewage control, forcing the adhesive to transform into a low-pollution category.

Food, medicine and other packaging are increasingly strict with safety standards. Soft packaging that directly touches food requires that the adhesive has no peculiar smell, is non-toxic and harmless, and does not precipitate harmful substances. Environmental-friendly laminated adhesive can avoid food safety hazards caused by solvent residues and meet product access standards.

 

The concept of market consumption has been continuously upgraded, and consumers have given priority to green and harmless packaging products. In order to enhance their reputation and market competitiveness, brand enterprises have adopted environmentally-friendly adhesives to make packaging, which has driven the upstream and downstream industrial chains to upgrade synchronously.

 

At the same time, the industry technology is constantly iterative, and the performance of waterborne and solvent-free polyurethane adhesive is gradually mature. The adhesive strength and temperature resistance and aging resistance can match the production requirements of composite packaging, which can not only replace the traditional high-pollution adhesive, but also reduce the cost of waste gas treatment and waste disposal, giving consideration to production benefits and ecological protection. Low-carbon life has become an industry consensus, which promotes the overall and steady development of polyurethane adhesives in the direction of clean and environmental protection.
