The future development direction of plastic bottles

There are many varieties of plastic bottles with different functions. The plastic bottle has a small specific gravity, is easy to color, and has strong plasticity. It can be made into various shapes of bottles and has a low price. It is suitable for mass production. In order to increase the decorative effect of plastic bottles, in addition to bottle printing, it can also be used in During production, coloring materials are added for coloring treatment to make bottles of various colors, and surface decoration can also be carried out by metal evaporation method, gold plating method and thermal printing method, to meet the needs of different grades of packaging. When packaging various lotions in plastic bottles, the bottle shape, color, transparency and various decorations and decorations used vary a lot. To highlight the characteristics of the product, to promote sales. For example, when using transparent glass bottles for packaging, generally only simple line printing is carried out to highlight the clear and transparent characteristics of the product to attract consumers. When packaging plastic bottles of various colors, the bottle body is generally decorated by printing or sticking labels. to convey product information. Win the favor of consumers. Carry out novel bottle shape and cap shape design, and at the same time cooperate with the bottle body pattern, to express the characteristics of the product to arouse the curiosity of consumers and stimulate consumers' desire to buy. Sometimes color-printed cartons, window-opening cartons and plastic bottles are used to form a sales package. The application range of plastic materials and their composite materials in cosmetic packaging is increasing, and the design of packaging containers, especially plastic bottles, tends to be diversified. The plastic packaging container is mostly obtained by the film molding method, and its shape is mainly determined by the molding method and the mold used, which is convenient for the manufacture of various special-shaped bottles. There are many kinds of plastic packaging containers with different functions, and the material of plastic containers determines its basic characteristics [4]. Plastic bottles commonly used for packaging cosmetics mainly include polyethylene bottles (blow molding), polyvinyl chloride bottles (injection molding, stretch blow molding), polyester bottles (stretch blow molding), polystyrene bottles (injection blow molding) molding), polypropylene bottles (extrusion blow molding), etc. With the continuous introduction of new technologies and new products, plastic containers have achieved the transparent characteristics that only glass had before, making plastic products unique in the cosmetic packaging market. 3.1.1 Transparent polypropylene (CPP) plastic bottle The development of transparent polypropylene (CPP) packaging bottle is a hot spot of plastic packaging at home and abroad in recent years. Compared with other transparent plastic resins, CPP has good gloss and transparency, and is highly appreciated and popular. 3.1.2 Transparent poly PET plastic bottle Transparent poly PET plastic bottle has now become a packaging container for daily chemical and cosmetic manufacturers. For example, some companies and brands such as Nais, Blue Moon, Kaimi, and Watsons are the first to use PET packaging containers for shower gels, skin care products, and washing products. PET is a high-strength, high-transparency plastic bottle produced by a stretch blow molding process, and the commonly used capacity can range from tens of milliliters to several liters; good transparency and gloss, good plasticity, impact resistance and and Dimensional stability, good chemical properties, good gas barrier properties; soft touch and other advantages. 3.1.3 PETG plastic bottles PETG plastic bottles have good application prospects in the packaging of cosmetics and personal care products. Its outstanding advantages are: glossy surface, comfortable hand feel, gorgeous color and transparent shade, chemical resistance, good impact resistance and toughness, and the transparency remains unchanged after anti-UV treatment. And its easy processing, recyclability and environmental protection properties are more in line with the requirements of modern manufacturers. At present, consumers have higher and higher requirements for the appearance and packaging of commodities, which makes cosmetic packaging design more and more important. In order to achieve beautiful appearance, good texture and durability, high requirements are put forward to the designer, and the good processing performance of PETG makes the design concept possible. 3.1.4 Nanomaterials Plastic bottles add a certain proportion of nanomaterials to the raw materials of plastic containers, which can improve the chemical properties of plastic containers, which have greater barrier properties, chemical resistance and UV resistance. Improve, the toughness of the container has also been strengthened, and at the same time can reduce a certain cost, the product is competitive. Such as: polyamide 6 nanoplastics. It is a high-grade packaging film material, polyester PET and PBT nano-plastics, with flame retardant properties and relatively pure barrier properties, instead of expensive polybutylene terephthalate (PBT) resin, it meets the requirements of food packaging and can be directly Packaging bottles for blowing beer and cosmetics. 3.1.5 Antibacterial plastic bottle The development of antibacterial plastic bottle for packaging can inhibit the generation of bacteria on the surface of the container. The inorganic metal (Ag) antibacterial agent is evenly dispersed in the blow molding bottle, and the antibacterial plastic container produced by the improved blow molding process has the characteristics of long antibacterial time, antibacterial effect and good antibacterial spectrum. The product has been tested, and the antibacterial rate is above 99%. The product is very popular in the market. It can be widely used in cosmetic packaging.
