Customer background
A Malaysian customer runs a cold drink products company and is looking for high-quality low-temperature resistant PET sheet for making ice cups that can be used in a frozen environment. These ice cups need to withstand temperatures as low as -20°C and maintain high transparency to display the contents.
Improvements to meet customer needs
Material formulation adjustment
Adding specific low-temperature toughening agents makes PET sheets less likely to crack or become brittle in a low-temperature environment.
Molecular structure optimization
Using a biaxial stretching process to improve the toughness and low-temperature impact resistance of the sheet.
Food safety certification
Ensure that the sheet meets Malaysian food contact material standards, such as FDA or EU standards.

Difficulties encountered and solutions
Low-temperature testing standards
Challenge: It is necessary to meet the impact resistance and toughness requirements under a variety of freezing conditions.
Solution: By simulating the actual environment of the customer, multiple low-temperature impact and use tests are conducted to adjust the modifier ratio and processing technology.
Transparency and toughness balance
Challenge: Improving toughness may lead to a decrease in transparency.
Solution: Select a low-temperature modified material with high transparency and strictly control production parameters.
Logistics and delivery
Challenge: The customer required urgent delivery while ensuring the quality of the sheet.
Solution: Optimize production scheduling and coordinate fast transportation with the logistics team.

Final results
Product performance: Provide 0.6mm thick low-temperature resistant PET sheet, which can be used in an environment of -20℃ with stable performance and high transparency.
Advantages of low-temperature resistant PET sheet:
- Low-temperature resistance: It can maintain good strength and toughness at sub-zero temperatures and is not easy to crack.
- Excellent transparency: It presents a clear appearance and is suitable for high-end ice cup packaging.
- Food-grade safety: It meets the safety standards of food contact materials.
- High impact resistance: It has excellent impact resistance even at low temperatures.
- Environmental protection and recyclability: PET sheets are recyclable and in line with the concept of sustainable development.
- When used for ice cups, low-temperature resistant PET sheets ensure that the ice cups will not deform or crack during freezing, transportation and use, maintain the beauty and practicality of the product, and are an ideal choice for ice product packaging.

Customer evaluation: Customers highly recognize the impact resistance and food safety of the sheet, and are satisfied with our efficient service and technical support.
