The important impact of plastic bottles in cosmetics packaging is that it is easy to transport, not easy to break, and can better cover cosmetics. However, not all plastic bottles can be used to package cosmetics. The state has imposed harsh requirements on cosmetic plastic packaging, and related companies must strictly abide by the relevant production and packaging systems. So what are the material requirements for plastic bottles for cosmetic packaging?
Generally speaking, plastic bottles used in cosmetics packaging are divided into PP, PE, K materials, AS, ABS, acrylic bottles, PET and so on. PET materials are used for the molding of cosmetic packaging plastic bottles, tube blanks are used for injection molding, and product packaging is used for blow molding. Acrylic radiation bottles have poor chemical resistance and often cannot be placed directly into the slurry. The cushions to be equipped are truncated and the filling is not too full to prevent adhesion between the liner and the acrylic bottle, which places higher demands on transport packaging. Scratches look particularly high, have high permeability, and feel particularly thick on walls, but at the cost of being quite expensive.
Plastics are many types of polymer synthetic materials. The advantage is:
(1) Good mechanical properties, light weight, convenient storage and transportation, easy to carry and use;
(2) Good barrier property, good sealing property and high transparency;
(3) Good processing performance, can be made into bottles, caps, films, bags and composite packaging materials of various sizes;
(4) Decorative coloring and printing performance. Drug identification, instructions, signs, barcodes can be directly inkjet or printed on plastic and will not fall off;
(5) Good chemical stability, weak toxicity, health and safety. The lid of the medicine can be made into a safety cap or a pressure cap, as well as a security mark. The disadvantages of plastic packaging containers are that they can easily carry static electricity, their surfaces are easily contaminated, and discarded materials can cause environmental pollution, and the recycling process is difficult.
As a "home-made flower" for many years of packaging, plastic bottles will still occupy an important position in future cosmetic packaging materials. The high strength, light weight, and non-fragility of plastic have been the advantages of plastic containers. Not only that, but also a variety of plastic packaging designs can be implemented and implemented in production in a short time. These characteristics make plastics neutral in the competition for cosmetic container materials.
