Cosmetics plastic container material safety

Update: 16-06-2020

The stability of cosmetics plastic packaging materials […]

The stability of cosmetics plastic packaging materials is very worthy of attention. A cosmetics plastic container may be safe during its delivery and distribution, but when consumers use it, problems may arise. For example, under the influence of high temperature environment, whether plastic bottles can keep the harmful substances in the material from transferring. People repeatedly use a plastic cosmetic container for a long time, how to make it will not change as it leaves the factory. Secondly, the external label of plastic cosmetic container packaging should be more able to let people understand the relevant information of food. Plastic cosmetic containers should be marked with taboos, etc., which are more complete and detailed.
  Secondly, the safety of cosmetics plastic packaging materials is mainly manifested in the migration and dissolution of toxic and harmful substances remaining in the material, which leads to food pollution. Plastics are easy to be charged, and they are easy to adsorb fine dust impurities and microorganisms, which causes pollution to food. But we can be relatively assured that plastic PE (polyethylene), PP (polypropylene) and PET (polyester) are commonly used in food packaging, because less additives are used during processing, the resin itself is more stable, and their safety is very high.
Plastic packaging is widely used. Plastics are collectively called polymer compounds. The main base materials are synthetic resins, and synthetic resins mainly include fillers, plasticizers, flame retardants, colorants, antistatic agents, foaming agents, stabilizers, It is composed of additives such as lubricants, which are artificially synthesized through chemical processing. The plastic containers we see are used in our daily life: polystyrene, PS, instant noodle boxes, fast food boxes, polycarbonate resin PC Water cups, kettles, baby bottles, poly(para-phenylene glycol) esters, PET, mineral water bottles, carbonated beverage bottles, cosmetic containers, polyvinyl chloride, PVC, pipes, electrical enclosures, plastic doors and windows, leather, polypropylene, PP, microwave oven lunch boxes, Modified raw materials, industrial containers, 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 commonly used materials for cosmetic plastic containers, there are AS or ABS transparent gums, PMMA acrylic materials, etc. Plastic containers account for a large proportion of more than 75% in the packaging of cosmetics. The main reason is that in addition to the plasticity and convenient filling of the material, transportation, density, printing, and recycling are also the main factors that consider the large-scale use of plastic containers. However, the shortcomings of plastic containers are also obvious. Poor light resistance, low heat resistance, poor melting resistance, etc. are fatal shortcomings of plastic containers, mainly because they cannot perform the necessary high-temperature steam sterilization and light sterilization processes. Its poor melting resistance is even a dead spot for some cosmetics. Some corrosive cosmetics will also directly react with plastic containers, such as acidic, oily, and easily oxidized categories, which are very harmful to the human body. For example, essential oils, makeup removers, water oils, and perfumes, cosmetics, etc. Therefore, it is better to choose pure white or transparent cosmetics for plastic containers. The reason is that it is easy to observe the characteristics of cosmetics and avoid the dissolution of bottle fuel to form pollution.
Various additional processes on cosmetic plastic container bottles, after processing through these processes, make the plastic bottles exhibit certain characteristics of glass bottle packaging. For example, plastic bottle packaging is frosted, so that the outer packaging of plastic bottles looks similar to glass bottles. There are many such crafts, and there are many for our merchants to dig. Improving the quality of plastic bottles is also a feasible direction. For example, some health products plastic bottles use metal caps, and the unique design of the plastic bottle body makes the overall quality of the plastic bottle greatly improved.
