Features and advantages
Excellent low temperature resistance
After low temperature modification, PET sheet can maintain toughness and impact resistance at extremely low ambient temperatures (such as -20℃ to -40℃) to avoid cracking.
High transparency and gloss
Transparent like glass, smooth surface, can perfectly display the visual effect of the package contents, especially suitable for high-end market needs.
Good mechanical strength
PET sheet has high strength and excellent tear resistance, and can maintain its physical stability under low temperature impact.
Food grade safety
PET material complies with FDA and EU food contact material standards, suitable for packaging frozen foods, ice cups, etc.
Chemical corrosion resistance
It has good tolerance to weak acids, weak alkalis and most oils and fats, suitable for a variety of environments.
Environmentally friendly and recyclable
PET sheet is 100% recyclable, which helps to recycle resources and conforms to the development trend of green economy.
Application fields of low-temperature resistant PET plastic sheets
Food packaging
Frozen food: ice cream boxes, quick-frozen dumplings, frozen meat packaging boxes.
Cold drink containers: such as low-temperature ice cups, iced beverage bottles.

Production process of low-temperature resistant PET sheets
Raw material preparation
Select high-purity PET resin, add low-temperature toughening agents or copolymer modified materials to ensure the stability of material properties.
Blending and melt extrusion
Use a twin-screw extruder to evenly mix PET and modifiers, and optimize the rheological properties of the material by controlling the temperature.
Forming and stretching
In the biaxial stretching process, the molecular chains are rearranged to increase the impact resistance and low-temperature performance of the sheet.
Cooling and cutting
Precisely control the cooling process to ensure dimensional stability, and cut into rolls or sheets according to needs.
Quality inspection and packaging
Inspect the thickness, transparency and low-temperature impact resistance of the sheet, and finally package it in a standard way for transportation.
How to achieve low-temperature modification of PET?
Adding modifiers
Improve the toughness of the material by introducing rubber-like polymers or comonomers.
Molecular structure optimization
Use biaxial stretching technology to adjust the molecular arrangement and improve the low-temperature impact resistance.
Special formula design
Adjust the raw material ratio and processing parameters to improve the flexibility and stability of the material at low temperatures.
Differences between low-temperature resistant PET and ordinary PET sheets
Low-temperature resistance
Low-temperature resistant PET sheets can be used normally in an environment of -40℃, while ordinary PET sheets may become brittle at low temperatures.
Flexibility
Low-temperature resistant PET materials are more resilient and suitable for freezing and low-temperature impact scenarios.
Slightly higher cost
Due to the need for special modification, the cost of low-temperature resistant PET sheets is slightly higher than that of ordinary PET, but the cost performance is better.
Market prospects of low-temperature resistant PET sheets
With the rapid development of cold chain logistics and frozen food markets, the demand for low-temperature resistant PET sheets continues to grow. Especially in the fields of food safety, pharmaceutical cold chain and industrial protection, PET sheets have a market advantage with their environmental protection, high efficiency and stability. At the same time, more and more companies are paying attention to sustainable development. The recyclability and energy saving of PET sheets are more in line with future trends, and the market size is expected to continue to expand.
