Lotte Chemical Localizes High-Temperature Adhesive Material for Food Packaging... Begins Commercialization

Localization of Adhesive Materials Previously Dependent on Imports
Accelerating Entry into the Food Packaging Market

Lotte Chemical has developed and commercialized an adhesive material for food packaging that maintains stable adhesion even at high temperatures. By localizing a product that previously relied on imports, the company is being recognized for enhancing the stability of domestic packaging material supply.

On October 28, Lotte Chemical announced that it has independently developed an adhesive material for multilayer packaging containers that can maintain adhesion performance in high-temperature environments, and has begun supplying it to manufacturers of instant rice containers. This new material increases the interlayer adhesion of multilayer packaging sheets, ensuring stable performance without deformation even during high-temperature sterilization or microwave heating.

The new material effectively bonds polypropylene (PP) and ethylene-vinyl alcohol (EVOH) films, which typically do not adhere well to each other, thereby significantly enhancing moisture and oxygen barrier properties. As a result, it helps maintain the freshness of packaged foods and extend their shelf life. In addition to instant rice containers suitable for microwave cooking, the material can also be applied to retort foods, frozen foods, and packaging that requires high-temperature sterilization, among various product categories.

Lotte Chemical succeeded in commercializing the product after approximately three years of research and development, meeting all major quality evaluation criteria such as safety, odor, and moldability. The company plans to reduce import dependence and accelerate the expansion of both domestic and international food packaging markets through this localization effort. A Lotte Chemical representative stated, "By localizing a food packaging material that offers both high-temperature adhesion and heat resistance, we expect to enhance the competitiveness of the domestic food industry."
