American Packaging Waterborne Adhesive Introduced to China

Recently, Rohm and Haas Company of the United States merged the famous adhesive company, the United States of America, and introduced its water-based composite adhesive, which has achieved great success in Europe and the United States, into the Chinese market, bringing an environmental revolution to the Chinese packaging industry. .

This adhesive is a water-based polymer emulsion that emits 100% of water vapor instead of harmful solvents during the production of composite packaging. The finished packaging product eliminates residual solvent and does not produce any odor. . For packaging manufacturers, the biggest advantage of this type of water-based adhesive is that it can be applied to existing dry-process compounding lines. It does not require equipment modification and can be used directly without adding new investment. The overall cost of water-based adhesives is also no higher than that of existing domestic solvent-based adhesives. There is no need to worry about hygienic performance when using water-based adhesives. This adhesive is fully compliant with the US Food and Drug Administration FDA standards.

American Rohm and Haas company's water-based adhesives are mainly single-component and two-component two major product lines. The characteristics of the single-component series are as follows: First, it is not necessary to use the sizing and it is used directly. The operation process is simple, the cost is low, and the production efficiency is high; the second is that the packaged product made of water-soluble adhesive has excellent applicability, and the third is that the finished product does not need to be matured, and the post-processing such as slitting and bag making can be performed. Suitable for the current food manufacturers to shorten the supply cycle needs; Fourth, water-based adhesive film and aluminum film in the composite performance is more prominent, will not be like the traditional rigid solvent like polyurethane glue caused by the transfer of aluminum film; Waterborne adhesives are versatile and can be applied to most packaging substrates. Due to the limited peel strength, one-component water adhesives are mainly used in lightweight packaging such as puffed foods, biscuits, confectionery, condiments, and pharmaceuticals. The two-component water-based adhesives break through the peel strength, and the technical problems of heat resistance and chemical resistance can be used in high-end products such as steamed foods and liquid packaging. At present, this new type of water-based adhesive has been applied by many famous packaging manufacturers.
