With the development of economy and the improvement of living standards, China’s beverage industry has developed rapidly, and has developed from the single glass bottled soda and carbonated drinks in the 1970s and 80s to the today’s situation of energy drinks, plant protein, light drinks and a lot.
Beverage packaging industry also followed the diversification trend, breaking the past single glass container monopoly market pattern, metal, plastic, paper and other materials have been applied in beverage packaging, metal cans, PET bottles, PP bottles, Tetra Pak bag, Kangmei bag, roof bag, black and white film and other packaging ink appeared.
In the current beverage market, plastic bottles occupy the main position in the packaging applications of tea drinks, carbonated drinks, fruit juice and bottled water. Specifically, they are divided into the following materials:
PE is the world’s most productive synthetic resin and the most consumed plastic packaging material. Polyethylene products are divided into low density, medium density and high density three kinds. Using the characteristics of PE hot sealing performance, the production of a variety of composite materials made containers, can hold fruit juice and other drinks.
Identification features: generally speaking, PE packaging feels smooth, soft texture, lubrication, with the teeth appear slightly soft.
The development of polypropylene transparent packaging bottles is a hot spot of plastic packaging at home and abroad in recent years. With the development of transparent modifying agent —— nucleator, in ordinary PP 0.1%~0.4% sorbitol xylene (benzaldehyde) nucleator, produced by high transparent PP bottle can be widely used for heat sterilization such as concentrated juice need high temperature filling beverage packaging, the price is appropriate, pressure and temperature resistance, is PS, ABS, PET, PE bottle.
Identification features: generally speaking, PP texture is hard, feel slightly rough, after the crease will have white, the color is more white than PE.
PVC It can be roughly divided into hard products, soft products and paste products. The PVC bottles produced by injection and blowing method with no suture, uniform wall thickness can contain gas drinks such as cola and soda; The PVC bottles produced by extrusion blowing method are only suitable for fruit juice and mineral water.
4. PET or PETP
The PET bottle produced by two-axis extension blowing molding method has the characteristics of “large capacity, transparent, intuitive, light and easy to open, refrigerated, easy to carry, strong and recyclable”, which provides a broad market prospect for its development. From the perspective of the market share of the world’s major beverage countries, PET bottles accounted for more than 70% of the carbonated drinks, fruit juice drinks, tea drinks and bottled water beverage packaging.
Identification features: with good transparency, high surface gloss, glass appearance, is the most suitable plastic bottle instead of glass bottle.
The above are the most common beverage plastic bottles in life, I hope it can help everyone.
