Although the number flip cap of glass bottles used in the market is now more than that of plastic bottles, the development prospects of plastic bottles are immeasurable, because plastic bottles have advantages over glass bottles in many respects. The price of plastic bottles is relatively cheap, and it is more resistant than glass bottles. It is not so easily damaged and broken. It is not easy to cause damage during transportation. At the same time, it has a very large sales market, such as many. Medical medicines require plastic bottles for packaging. In addition, the continuous use of plastic bottles that can be recycled has further expanded the use of plastic bottles specializing in the production and processing of PET plastic bottles, spray bottles, jars, cosmetic bottles, daily chemical packaging containers and other products, price concessions, welcome to order for you honey plastic bottle packaging.
The main function is to protect honey from being carried, transported and preserved. It is closely related to people's health. In order to adapt to the concept of protecting the environment, Yueliang Plastic Products Co., Ltd. is developing new types of recyclable plastic bottles to contribute to the protection of the environment. PET resin is a typical crystalline polymer, but its crystallization rate is slow. Through the crystallization treatment, the performance of the article can be greatly adjusted to suit the needs of the application. Compared with crystalline resins such as polyethylene and polypropylene, the macromolecular chain has a relatively high rigidity the presence of a sub-benyl structure, and thus the crystallization rate is much slower. The PET resin itself has good thermal stability, but is prone to degradation in the presence of moisture.
As a result of the degradation, the molecular weight of the is significantly lowered, and the intrinsic viscosity and the mechanical strength of the article are correspondingly lowered. Dongyang Shuilifang packaging supplies specializing in the production and processing of plastic bottles, spray bottles, jars, cosmetic bottles, daily chemical packaging containers and other products, price concessions, welcome to order Shulifang packaging for you: plastic products container varieties The main types of plastic container are mainly high density polyethylene, low density polyethylene and polybenylene. It is therefore necessary to exclude the water content as much as possible before molding.
It is generally considered that the water content is less than , and at least 0.01% or less. The good barrier properties of plastic make it the most carbonated beverages, packaging materials, juices, milk, dairy products, tea drinks, mineral water and other foods and beverages. In China, plastic bottles are made from petroleum, and the production of plastic bottles reaches 3 million tons of oil, which consumes more than 18 million tons per year, and it also causes enormous environmental pressure. The recycling of recycled plastic bottles is conducive to saving resources. Since the products packaged in plastic bottles have their unique advantages, the packaging form of medicines is constantly changing.
