Background Cosmetic packaging material customers originally chose glass bottled products. In order to adapt to the development trend of the industry and combine with the relevant national energy saving and emission reduction policies, they are considering changing to PET plastic bottle products. The cosmetic packaging material packaging production director focuses on glass bottles and PET A brief description of the advantages and disadvantages of plastic bottles
1. The development history of PET
The Chinese name of PET is polyethylene terephthalate. In the year, the United Kingdom issued the first patent for preparing PET, which was later purchased by DuPont of the United States, and a production facility was established in the year, the first in the world to realize industrialized production. . Since the 1980s, PET has made breakthrough development as an engineering plastic. At present, PET has become one of the five major engineering plastics.
Two, PET plastic bottle processing technology
Polyester chips are baked at ℃ for up to four hours, then melted at ℃, and then injected into preforms, then quickly cooled to ℃, after biaxial stretching, and blown by clean high and low pressure compressed air (It can be formed in one step or in two steps, which is commonly referred to as 'one-step' and 'two-step' blowing). PET bottles have high strength, good transparency, non-toxic, anti-permeation, light weight, and production High efficiency has been widely used, the main advantages
, Good processing characteristics can be processed into products of various shapes according to use requirements, and it is suitable for mechanized mass production.
、Light weight and density around .g/cm, due to its light weight, it can reduce the weight of the packaged product;
, the specific strength is high, the rigidity is close to or even higher than that of steel, which belongs to a kind of light and high-strength material;
、The thermal conductivity is less than that of metal //, it is an ideal heat insulating material;
、Good chemical stability plastics have good corrosion resistance to common acids, alkalis, salts and greases;
, Good electrical insulation is a poor conductor of electricity, and its electrical insulation is comparable to ceramics and rubber.
, Good performance design, can be made into products with various special properties by changing the formula and processing technology;
、The decorative PET can be made into transparent products or products of various colors, and the color is beautiful and durable. It can also be made with various patterns by advanced printing, embossing, electroplating and bronzing technology. , Pattern and surface three-dimensional, metallic products.
Main disadvantages
、Easily aging PET plastic bottles will be hard and brittle when placed outdoors for a long time under the influence of sunlight, air, heat and environment;
, Flammable plastic has a higher ignition point than the bottom of a glass bottle, once it is ignited, it is difficult to extinguish and emits a lot of smoke;
, Poor heat resistance Ordinary PET chip products can only withstand temperature below ℃, and products made by changing heat-resistant materials and secondary crystallization processes can heat up to above ℃;
3. The main components and advantages and disadvantages of glass are silica and other oxides.
Advantages Glass has good transparency, no pollution, strong fashion, rich shapes and wide applications, and low cost. The mould has precise forming dimensions, can manufacture light and thin products, and the colors are rich and varied, and the craftsmanship is exquisite.
Disadvantages Disadvantages are fragile, not easy to manufacture thick and heavy products, and poor temperature resistance of glass products are easy to burst due to temperature changes. In addition, although they are fashionable, they are also easily outdated.
Summary pet plastic bottle combines the texture of glass bottle but maintains the characteristics of plastic bottle, that is, it can achieve the appearance of glass bottle, but it has the advantages of not fragile, safe, environmentally friendly, and easy to transport than glass bottle; and it is recyclable Create particles, energy saving and environmental protection. Glass has good light transmission performance, but it is fragile and easy to hurt people. At present, many countries and large domestic supermarkets only place glass bottle packaging on the lowest shelf of the shelf, which cannot attract customers' attention and affect sales. Therefore, PET plastic bottles have maintained high growth for many years. If you also want to switch to PET plastic bottles for products, please contact cosmetic packaging materials.
