The Differences Between PP Material and PE Material for Lunch Boxes

In our daily life, we all use lunch boxes. Many people think that fresh-keeping products are mostly made of PE plastics. In fact, PP plastics can also be used to make lunchboxes. Let's follow CNCROWN to learn about the difference between the PP material and the PE material of the lunch box! The difference between the two is listed as follows.


Ⅰ. PP and PE plastic bento lunch boxes are both safe to use


PP and PE plastic bento lunch boxes are both highly hygienic plastics that are safe to use. PP material has food-grade plastics that meet national standards, so it can be used for food packaging.


Ⅱ. The PE plastic bento lunch box is more resistant to low temperature than the PP


We all know that PE plastic is plastic with strong cold resistance, and it can still be used normally at -60 degrees Celsius, so what about the cold resistance of PP plastic? PP plastic is a kind of lightweight plastic, which is mostly used in the home appliance and automobile industry and is used for food packaging products, mainly because of its strong hygiene. The maximum cold resistance temperature of PP plastic bento lunch boxes is -35 degrees Celsius. Once the temperature is below -35 degrees Celsius, PP plastic products will become brittle.


Ⅲ. The PP plastic bento lunch box has good heat resistance


The maximum cryogenic temperature of refrigerators is -24 degrees Celsius, and the temperature of the fresh-keeping layer is 3-10 degrees Celsius, so PP plastic is suitable for heated bento boxes. Another important reason for using PP plastics to retain freshness is that it has an excellent heat resistance and can continue to be used at a temperature of 100 degrees Celsius.
