The stability of cosmetic plastic bottle packaging materials is of great concern. A cosmetic plastic bottle may be safe during its delivery and distribution, but when consumers use it, problems may occur. For example, under the influence of high temperature environment, whether the plastic bottle can keep the harmful substances in the material from being transferred. People repeatedly use a plastic cosmetic bottle for a long time, and how to keep it unchanged from the factory. Secondly, the outer label of plastic cosmetic bottle packaging should be more able to let people know the relevant information of food. Plastic cosmetic bottles should be marked with taboos of origin, etc., more complete and detailed. Secondly, the safety of cosmetic plastic bottle packaging materials is mainly manifested in the contamination of food caused by the migration and dissolution of toxic and harmful substances remaining in the material. Plastic is easy to be charged and easily adsorbs dust impurities and microorganisms, which can cause food pollution. However, we can be assured that plastics such as PE (polyethylene), PP (polypropylene), and PET (polyester) are commonly used in food packaging. Because the additives are used less during processing, the resin itself is relatively stable, and their safety is very high. Plastic packaging is widely used. Plastics are collectively referred to as polymer compounds. The main base material is synthetic resin. Synthetic resins mainly include fillers, plasticizers, flame retardants, colorants, antistatic agents, foaming agents, stabilizers, It is composed of additives such as lubricants, and is artificially synthesized through chemical processing. We see plastic bottles, and look at the application scenarios of plastic packaging in our daily life: polystyrene, PS, instant noodle boxes, fast food boxes, polycarbonate resin PC Water cups, water bottles, baby bottles, poly (p-phenylene glycol), PET, mineral water bottles, carbonated beverage bottles, cosmetic bottles, polyvinyl chloride, PVC, pipes, electrical enclosures, plastic doors and windows, leather, polypropylene, PP, microwave lunch boxes, Modified raw materials, industrial bottles, polyethylene, PE, food packaging bags, tableware, plastic modification, high and low density polyethylene, HDPELDPE, cleaning supplies, bath products, plastic films, etc. In addition to the above commonly used materials for cosmetic plastic bottles, there are also AS or ABS transparent plastic, PMMA acrylic materials. Plastic bottles account for a large proportion of the use of cosmetics packaging, up to 75%, in addition to the plasticity of the material, convenient filling, transportation, density, printing, recycling, etc. are also the main considerations for the large-scale use of plastic bottles. However, the disadvantages of plastic bottles are also obvious. Poor light resistance, low heat resistance, and poor melting resistance are all fatal disadvantages of plastic bottles. The main reason is that the necessary high-temperature steam sterilization and light sterilization processes cannot be performed. Its poor melting resistance is also a dead point for some cosmetics. Some corrosive cosmetics also directly chemically react with plastic bottles, such as acidic, oily, and easily oxidizable products, which are very harmful to the human body. Such as essential oils, makeup oils and perfume cosmetics. Therefore, it is better to choose pure white or transparent cosmetics for plastic bottles. The reason is that it is easy to observe the properties of the cosmetics and avoid the fuel from dissolving to form pollution. Various additional processes on cosmetic plastic bottles, after processing through these processes, plastic bottles exhibit certain characteristics of glass bottle packaging. For example, plastic bottle packaging is matte, so that the plastic bottle packaging looks similar to glass bottles. There are many such processes, and there are many to be tapped by our merchants. Improving the temperament of the plastic bottle is also a feasible direction. For example, some health care plastic bottles have metal caps, and the unique design of the plastic bottle body has greatly improved the overall temperament of the plastic bottle.
