During the visit to the factory, the customer asked about how to improve the toughness of RPET sheets when used for blister packaging. This question hits the nail on the head, because the toughness is directly related to the quality and service life of blister packaging products.
In response to the customer’s question, the technical department manager of Xingjinya Industrial Co., Ltd. gave a detailed and professional answer.

First of all, in the selection of raw materials, the company strictly controls the quality of RPET resin and selects resins with high purity and good performance to lay the foundation for improving the toughness of the sheet from the source.
Secondly, by optimizing the production process, the parameters of each link are precisely controlled. During the extrusion process, the temperature and speed should be adjusted appropriately to ensure that the resin is fully melted and extruded evenly, thereby reducing internal stress and thereby improving the toughness of the sheet.
Cooling is also crucial. Advanced cooling technology is used to cool the sheet at an appropriate speed to avoid uneven structure caused by too fast or too slow cooling and further enhance toughness.
In addition, the company also pays attention to adding appropriate additives. These additives are well compatible with RPET resin and can significantly improve the toughness of the sheet without affecting other properties.
Xingjinya Industrial has always been guided by customer needs and continues to carry out technological innovation and quality improvement. This exchange with Japanese customers not only demonstrated the company’s professional strength and technical level, but also provided new impetus and direction for the company’s future development.
It is believed that in the future, Shenzhen Xingjinya Industrial Co., Ltd. will continue to work intensively in the field of RPET sheets, provide customers with more high-quality and high-performance products, and lead the new trend of industry development.
