What is the maximum and minimum temperature that BOPP synthetic paper can withstand?

The maximum and minimum withstand temperatures of BOPP synthetic paper (biaxially drawn polypropylene synthetic paper) are affected by factors such as the specific material formulation, production process and additive use, so there is no absolute fixed value. However, according to the existing information and industry knowledge, we can roughly estimate and explain the temperature range of BOPP synthetic paper:

Maximum withstand temperature

Melting point and heat seal temperature: The melting point of BOPP film is high, generally above 160 degrees Celsius, which provides it with good high temperature resistance. However, it is important to note that the melting point is not the same as the highest temperature that the material can withstand for a long time. In practical applications, the long-term use temperature of BOPP synthetic paper in a high temperature environment may be lower than its melting point.

Recommended processing temperature: In some data mentioned that the recommended processing temperature of BOPP film is 240-260 ° C, but this refers to its temperature control range in the processing process, rather than its long-term maximum temperature.

Practical application: Considering the application of BOPP synthetic paper in packaging, labeling and other fields, the maximum temperature it can withstand for a long time may be limited by the specific application environment and conditions. In general, in conventional packaging applications, the use temperature of BOPP synthetic paper usually does not exceed 120 ° C, which is a conservative estimate based on its heat resistance.

Minimum bearing temperature

Cold resistance: BOPP film has good cold resistance, and its cold resistance is better than the general PP film. The specific minimum temperature that can be tolerated will be affected by factors such as material formulation and additive use.

Practical application: It is mentioned in some data that the BOPP synthetic paper adhesive material can withstand low temperature to -40℃, which indicates that with the support of specific formulas and additives, BOPP synthetic paper has a good low temperature adaptability. However, this does not mean that all BOPP synthetic paper can withstand such a low temperature, the specific needs to be judged according to the product specifications and instructions.

In summary, the maximum and minimum withstand temperatures of BOPP synthetic paper will be affected by many factors, and an exact fixed value cannot be given. In practical applications, it is recommended to judge its temperature resistance range according to the specifications and instructions of the specific product, and avoid using it beyond its tolerance range to avoid performance degradation or damage. At the same time, it is also necessary to note that there may be differences and errors in information from different sources, so it is necessary to consider many factors comprehensively when making judgments and decisions.
