Today the plastic bottle manufacturer Qingzhou Mihe Integrity Plastic Packaging Co., Ltd. is here to tell you. The more common materials for plastic bottles are PET, PP, PE, PC, etc. The following are the characteristics of these materials:
PET is transparent, non-toxic, impact-resistant, and not resistant to high temperature. It is generally filled with mineral water, cola, peanut oil, and cosmetics. It needs to be filled cold and used for one-time use (can not be sterilized at high temperature). PP is non-toxic, transparent, and has certain heat resistance and impact resistance. It is generally used for fruit juice drinks and shampoo. It can be hot-filled (more important for fruit juice drinks). It cannot be sterilized in a pressure cooker, and the transparency is not good.
PE: PE bottles are similar to PP bottles, with better toughness than PP, but poor rigidity and heat resistance, and good solvent resistance. Plastic soy sauce bottles seem to be PE, and a small amount of wine and kerosene can be temporarily installed. PC is transparent, impact-resistant, high-temperature resistant, and the material is relatively expensive. Mineral water bottles are used more and can be sterilized by high-temperature steam. Food Grade Bottle The key to the choice of materials for plastic bottle manufacturers is to see what you want to pack, whether there is corrosiveness, appearance requirements, etc., and decide what material to use.
Plastic bottle packaging has become the mainstream packaging mode in my country, and the demand from all walks of life occupies a high proportion of packaging. However, as people’s awareness of environmental green and health is getting higher and higher, high-temperature plastic bottles are also subject to glass-packaged plastic bottles. In the case of high temperature, whether it is stable or not, whether it will release harmful substances, is being questioned by the market. How to increase the high temperature resistance of plastic bottle packaging?
I don’t know if you have encountered such a thing when you were young, just to bring boiled water to school, pour the freshly boiled boiled water into a mineral water bottle or other beverage bottle, and then find that the boiled water is not full, and the plastic bottle has been deformed. terribly. This is because the heat-resistant temperature of ordinary plastic bottle packaging can only reach 70 degrees. In fact, according to scientific experiments, it has been found that plastic bottle packaging will release trace amounts of harmful substances when it is heat-resistant to 60 degrees. The thermal temperature is the standard. Some plastic bottles will release corresponding harmful substances according to the objective temperature such as the weather temperature.
Therefore, according to the packaging characteristics of various plastic bottle manufacturers on the market, R & D personnel are also studying the high temperature resistant plastic bottle materials PET, PP and BOPP, etc., to improve the factor composition of the material and increase its heat resistance.
