The high temperature resistance of food plastic bottles is not only reflected in the irradiation of the hot sun, but also in the long chain of use it has experienced. In this chain, the performance of high temperature resistance is particularly important. The production of food plastic bottles has always been under strict standards and supervised by relevant departments. Therefore, at this stage of the production process, food plastic bottles are relatively safe for food. However, from the process of production to filling, and then to logistics, it is impossible to guarantee whether the food plastic bottles that finally reach consumers are still as good as when they left the factory.
The safety and stability of food bottle packaging in a high temperature environment has now attracted everyone's attention. The first is in the filling of food plastic bottles. Now more and more foods are sterilized at high temperature, which requires food plastic bottles to have a relatively high high temperature resistance index, otherwise the safety of food plastic bottles will be difficult to guarantee during the filling process.
Secondly, in the process of transportation and shelves, the weather in summer is hot, and the temperature in the transportation compartment is higher. In such an environment, food plastic bottles need to maintain the stability of their packaging and ensure high temperature resistance.
