[China Packaging Network News] A specialized mold release agent, scientifically known as polydimethylsiloxane emulsion, was developed specifically for plastic processing technology. This innovative product was supported by Shanghai Rongxin Plastic Co., Ltd., with strong backing from the Shanghai Bureau of Quality and Technical Supervision. The company successfully completed trial production and passed a rigorous quality audit conducted by experts from the Shanghai Quality Supervision Bureau and other relevant organizations at the end of 2014. The product's standards have been officially registered with the Shanghai Bureau of Quality Supervision, and a patent application has been submitted.
For many years, there was a lack of clear specifications for materials used in the plastic blister packaging process, and these were not included in GB9685. As a result, no domestic manufacturers produced release agents specifically for blister technology. Imported alternatives were costly, had long lead times, and had limited shelf lives, making them unaffordable for most companies. Additionally, trading companies were hesitant to import such products due to the high costs and logistical challenges. Moreover, different regulatory agencies in Europe and the United States often had varying requirements for the same product, leading to confusion and instability within the plastics industry.
To address these issues, the company developed a food-grade plastic film release agent tailored for use in the food packaging sector. This breakthrough solution effectively resolved long-standing challenges in the plastic industry and filled a critical gap in the domestic market.
Plastic packaging is one of the most widely used materials in the food industry. Plastic food trays are an essential part of daily life, with a vast number of various shapes and sizes produced using advanced plastic technology. The successful development of a food-safe release agent ensures that food remains safe when in contact with packaging materials. It also plays an important role in educating consumers about food safety and promoting greater awareness of the importance of safe packaging practices.
