More than 50% of food flexible packaging companies in Europe and the United States already use water-based adhesives or solvent-free adhesives. However, the development and promotion of solvent-based adhesives in China is very slow. The substitution process is blocked and lack of funds is an important factor. Both solvent-free products and water-based products require a large amount of heat during their production and use. The solventless laminating machine is expensive and requires high operating personnel. It takes a long time for large-scale promotion.
On the other hand, compounding quality is more likely to occur when solvent-free products are compounded, and the coating performance of water-based adhesives is poor, and the wettability to composite substrates is poor, resulting in low adhesion. These factors have also limited its promotion in China to some extent.
