Pet bottles can not be used for a wide range of purposes, from cosmetic packaging to food packaging to medical packaging. This is inseparable from the advantages of pet bottles. Compared with plastic bottles of other materials, pet bottles have many unique advantages. The first is that the pet bottle is transparent and has a strong plastic appearance, which makes various exquisite outer packaging bottles appear on the market shelves. The second is that the pet bottle is light and thin, but has good toughness and pressure resistance, which saves costs and can effectively reduce transportation weight. The third is that the stability of pet bottles is much better than that of general plastic bottles, which makes it have a good market space in the fields of cosmetics, medicine, and food.
Whether pet plastic bottles can be reused has always been a topic of constant debate. Both the pros and the opposition have strong evidence that fits the argument, and no one can convince anyone. PET plastic bottles can be reused, but should not be used multiple times. Pet bottles cannot be used repeatedly for a long time, especially in harsh environments where pet bottles can be reused at high temperatures, the stability of pet bottles will deteriorate and harmful substances are likely to be released. Secondly, if the pet bottle is only used for a short period of time, the problem is not big. It is best not to use the bottle again for the packaging of food, medicine and other products.
When conditions permit, pet plastic bottles can be reused, because the recycling of PET plastic bottles can not only solve environmental problems, but also can be used as a new raw material resource to alleviate the contradiction of China's insufficient PET raw materials. The recycling of PET plastic bottles is in line with practical problems and is of great benefit to environmental protection, resource conservation, and sustainable development.
