The continuous safe operating temperature ranges from 80–100℃. Within this range, the sheet maintains long-term structural stability without deformation, softening, or releasing harmful substances. It is suitable for food processing scenarios such as hot water cleaning and short-term steam sterilization.
The instantaneous high temperature resistance can reach 120℃ (for a duration not exceeding 30 minutes). Exceeding this temperature will cause softening and deformation. Prolonged exposure to environments above 100℃ will accelerate sheet aging, reduce toughness and shorten service life.
Note: Do not directly contact open flames or high-temperature heat sources, otherwise melting and combustion may occur.
Regular food-grade PP sheets retain good toughness and impact resistance in environments above -20℃ without brittle cracking. They are applicable to low-temperature scenarios including fresh food cold chain warehousing and refrigeration equipment accessories.
When the temperature drops below -20℃, the sheet’s toughness gradually decreases, impact resistance weakens, and it is prone to cracking upon external impact. Some modified food-grade PP sheets (e.g., those added with cold-resistant additives) can withstand temperatures as low as -40℃. For specific parameters, please refer to the product test report.
