Beverage industry plastic packaging has attractive business opportunities, in 2002, beverage production has reached 20.24 million tons, soda, juice, vegetables, Beverage plastic container demand is increasing.

In today's beverage market, PET plays an important role in the application of containers for tea, carbonated beverages, fruit juice and bottled water, and has a promising future. Such as Watson's "Ring Bao" bottle, Huiyuan's "He + She -" plastic bottle, Yanjing's "Dongdong" conical bottle, etc., PET makes the beverage packaging shape become colorful.

In the past two years, more and more new packages have appeared in China's beverage market. At present, there are several kinds of plastics used for beverage packaging.

1, PE (polyethylene):

PE is the world's largest synthetic resin and the most expensive plastic packaging material. Polyethylene products are divided into three types: low density, medium density and high density.

High density polyethylene (HDPE) has high crystallinity, good hardness, air tightness, mechanical strength, chemical resistance, so it is widely used to blow molding bottles and other hollow containers. The containers made of various composite materials can hold various beverages such as lemon juice, fruit juice and so on.

2, PVC (PVC):

PVC can be roughly divided into three categories: hard products, soft products and paste products. PVC bottles produced by injection-pull-blow method are seamless, with uniform wall thickness and can hold gas-containing beverages such as cola and soda water; PVC bottles produced by extrusion-blow molding are only suitable for fruit juice and mineral water.

3, PP (polypropylene):

The development of polypropylene transparent packaging bottle is a hot topic in plastic packaging at home and abroad in recent years. With the development of transparent modifier-nucleating agent, 0.1%-0.4% sorbitol *** (benzaldehyde) nucleating agent was added into ordinary PP. The high transparent PP bottle can be widely used in high temperature filling beverage packaging which needs heat sterilization such as concentrated fruit juice. T, PE bottle's new rival.

4, polyester (PET or PETP):

The PET bottle produced by two-axis extension blow molding has good transparency, high surface gloss and glass-like appearance. It is the most suitable plastic bottle to replace the glass bottle. In recent years, the production of PET bottles has developed rapidly in China, which is widely used in various kinds of tea drinks, fruit juices and other drinks that need hot filling, such as Pepsi Cola 600ml, 1.25L, 2L and 2.5L PET bottles. Different volumes of PET bottles aim at the different needs of individuals and families, and are well received by consumers.

From the market share of the world's major beverage giants, the share of PET bottled is over 70%. A survey showed that by 2007, the market sales of plastic for food and beverage packaging in Europe will increase from $4.91 billion in 2000 to $7.15 billion, with an average annual growth rate of 5.5%.

At present, China is also in the high-speed development stage of PET beverage packaging, the demand for polyester bottles is growing at double digits every year. The application proportion of PET bottle in domestic carbonated beverage packaging is 57.4%. It can be seen that polyester bottle packaging has occupied the main share of domestic beverage packaging market.

Consumers widely believe that PET bottles have the characteristics of "large capacity, transparent, intuitive, easy to open, refrigeration, easy to carry, strong, recyclable" and so on, which provides a wide range of development.
