How Many Degrees of Temperature Can PET, PP, and PE Withstand?



When it comes to packaging, choosing the right material can make all the difference. From IML rigid packaging for dairy foods to margarine containers, PET, PP, and PE are some of the most widely used plastics in food packaging. But have you ever wondered how much temperature these materials can withstand?

In this blog post, we’ll explore just that! So whether you’re a consumer or a manufacturer looking for durable and effective food packaging solutions, keep reading to find out everything you need to know about PET, PP, and PE.


PET containers are most commonly used for food and beverage packaging, such as dairy food packaging containers. This type of plastic is designed with high resistance to both hot and cold temperatures.

It is capable of resisting temperatures as high as 140 degrees Fahrenheit (60 degrees Celsius). But, it’s essential to note that prolonged exposure to elevated temperatures can cause PET containers to lose their shape gradually.


Polypropylene (PP) is a thermoplastic polymer. It’s used in iml PP food packaging applications such as that for a margarine container. It is also inert, making it suitable for direct contact with food.

PP also has excellent flexibility and can withstand temperatures up to 302 degrees Fahrenheit (150 degrees Celsius). This makes it ideal for use in microwaveable PP food containers and other applications where exposure to high temperatures is expected.


PE, or polyethylene, is a widely used thermoplastic polymer that’s known for its strength and flexibility. It is commonly used in the production of various products such as plastic bags, toys, pipes, and even bulletproof vests.

One of the key advantages of PE is its ability to withstand high temperatures. This makes it an ideal material for use in applications where heat resistance is crucial. PE can typically withstand temperatures up to 176-194 degrees Fahrenheit (80-90 degrees Celsius). This makes it suitable for use in many industrial settings.


It is important to understand the heat resistance of Pet, PP, and PE when choosing a material for your product. It is also important to remember that these materials may have different levels of resistance.

Knowing the temperature limits of these plastics will ensure that you choose the best material for your product’s safety and longevity. Always be sure to consult with your manufacturer or supplier to determine which plastic is best suited for your specific needs.
