Introduction To PET And PVC

PET is a kind of polymer material, the full name is polyethylene terephthalate, and it is widely used. The bottles of Nongfu Mountain Spring are made of it, which belongs to degradable recycling materials. A

PET mainly includes polyethylene terephthalate (PET) and polybutylene terephthalate (PBT). A

PET molecular structure is highly symmetrical and has a certain degree of crystal orientation, so it has high film-forming and flexibility. PET has good optical properties and weather resistance, and amorphous PET has good optical transparency. In addition, PET has excellent wear resistance and dimensional stability. A

Products made of PET have good transparency, non-toxicity, anti-permeation, light weight, high production efficiency, etc. and are therefore widely used. A

The main uses of PET are: all kinds of food, medicine, non-toxic and sterile packaging materials; high-grade packaging materials for textiles, precision instruments, electrical components; decorative products, color wall stickers, degradable decorative materials and other environmental protection is better Accessories; audio tapes, video tapes, movie films, computer floppy disks, metal coatings and photosensitive films, etc .; electrical insulation materials, capacitor films, flexible printed circuit boards and membrane switches and other electronic and mechanical fields.

PVC material is a kind of plastic decorative material. The full name is polyvinyl chloride material. It takes polyvinyl chloride resin as the main raw material, adding appropriate amount of anti-aging agent, modifier, etc., after mixing, calendering, vacuum blister and other processes Material. A

PVC material has the characteristics of light weight, heat insulation, heat preservation, moisture proof, flame retardant, and easy construction. It is one of the most widely used decorative materials among plastic materials.

Characteristics Of Plastic Packaging Box

Boxed packaging containers made of plastic have many characteristics such as low density, light weight, easy processing, etc. The appearance can be transparent or opaque. It is widely used in the food packaging industry. Blister packaging tray

Advantages of plastic packaging boxes:

1. Easy to form, as long as you change the mold, you can get different varieties of containers, and it is easy to form mass production.

2. The packaging effect is good, there are many kinds of plastics, easy to color, and bright color. Different types of packaging containers can be made according to needs to achieve the best packaging effect.

3. It has good corrosion resistance, acid and alkali resistance, oil resistance and impact resistance; and has good mechanical strength

Plastic is based on synthetic or natural polymer resins. After adding various additives, it is malleable under certain temperature and pressure, and it can fix its shape after cooling. The process of natural or synthetic polymer resin molecules in the molten state and the uniform distribution of auxiliary molecules around them is called plasticization. It has been reached. This process is called plasticized, but has not yet been reached. It is considered to have not been plasticized. Plastic packaging is one of the four major materials in the packaging industry: paper and cardboard account for 30%, plastic accounts for 25%, metal accounts for 25%, and glass accounts for 15%.

Plastic boxes are PVC / PET / PP / PS transparent plastic boxes, cylinders, lid boxes, handle bags, hanging clips and other related plastic products, which can be used for UV offset printing, silk printing, bronzing / Silver, matte and other printing effects have the characteristics of increasing user experience, permanent packaging durability, moisture resistance, waterproofing, high toughness, strong transportation safety performance, and upgrading product grades.

The main task of plastic box development

China is a large country in the world of packaging manufacturing and consumption. The proportion of plastic packaging in the total output value of the packaging industry has exceeded 30%. It has become a new force in the packaging industry and plays an irreplaceable role in various fields of food, beverage, daily necessities, and industrial and agricultural production. Packaging products and packaging materials in the plastic packaging industry have grown steadily, and new packaging materials, new processes, new technologies, and new products have continued to emerge.

From January to December 2006, China’s plastic packaging box and container manufacturing industry realized a cumulative total industrial output value of RMB 57,615,577,000, an increase of 22.83% over the same period last year; a cumulative product sales income of RMB 55,288,976,000, an increase of 23.15% over the same period last year, and a cumulative Total profit was RMB 3,124,783,000, an increase of 1.39% over the same period last year.

From January to December 2007, China’s plastic packaging box and container manufacturing industry realized a total industrial output value of 73,093,169,000 yuan, an increase of 26.72% over the same period of the previous year.

From January to October 2008, China’s plastic packaging box and container manufacturing industry realized a cumulative total industrial output value of 73,367,215,000 yuan, an increase of 21.48% over the same period of the previous year.

The use of plastics in rigid containers and flexible packaging is increasing. In terms of rigid containers, such as plastic trays and plastic barrels, the long-term cost is lower than fiberboard barrels due to reusability. Plastic vertical bags also have the potential to replace cardboard boxes as containers for dry foods such as pre-made cereals and sauces. In addition, plastic bottles are more and more used for the packaging of fruit juices and fruit drinks due to their light weight and impact resistance. In flexible packaging, pouches and films in plastic products will continue to be of great use in the fast food and retail sectors.

Major downstream users of plastic packaging

Plastic packaging has been widely used in electronics, food, beverages, alcohol, tea, cigarettes, medicine, health products, cosmetics, small appliances, clothing, toys, sporting goods and other industries and product packaging and other industries. Missing industries.

The main task of China’s plastic packaging industry is to develop new plastic molding equipment, gradually narrow the gap with foreign manufacturers, and fight against it in the market. Plastic packaging enterprises must change their development methods. They must stand at a new starting point to review and resolve the above contradictions and problems, take the scientific development concept as the lead, change the development concept, strengthen independent innovation, strengthen market awareness, and effectively promote the enterprise. development of.

Europe and the United States are the most developed countries in the plastic packaging industry in the world, and attach great importance to the research and development of advanced packaging machinery. According to Luo Baihui, secretary general of the International Mould, Metal & Plastic Industry Suppliers Association, there are a wide variety of packaging machinery and advanced equipment in Europe and the United States, but in order to be able to adapt to the competition in the international market, they are still researching and developing more advanced plastic packaging machinery and equipment.

In this situation, China’s packaging machinery industry enterprises should adhere to the “go global” development strategy and actively expand foreign markets. Luo Baihui pointed out that domestic packaging machinery industry enterprises should take offensive operations and actively participate in international cooperation and mergers among the same industry and even cross-industry enterprises. Through overseas investment and acquisition of foreign companies, their advanced technologies can be absorbed and absorbed as soon as possible. Localization, and thus enhance the international status of China’s packaging machinery industry.

The booming processing services industry has stimulated the strong demand for packaging machinery, which has provided good business opportunities for Chinese packaging machinery suppliers. In the competition with European and American companies, China’s packaging machinery companies have begun to appear. China is the world’s largest plastic production base, but the plastic packaging machinery industry upstream of the plastic packaging industry is basically monopolized by imported equipment.
