Plastic jars have not been around for a long time, but they have developed very rapidly and have replaced metal cans and glass bottles in many occasions, mainly because of its many advantages:

①Light weight. The material density of plastic jars is relatively small. Compared with the same volume of container quality, plastic jars are smaller than metal tin cans and glass bottles.

②Lower cost. The material cost of plastic jars is lower and the manufacture is easier, so the overall price is lower.

③ It can reliably protect the product. The can body is made of a variety of composite materials, which has good chemical stability and barrier properties; the combination of the bottom, the lid and the can body adopts a reliable sealing structure, so the contents can be reliably protected.

④ Good mechanical strength. Although the mechanical properties of plastic jars are slightly lower than those of metal cans and glass bottles, they are sufficient for packaging general products, and the problem of strength damage rarely occurs.

⑤The shelf effect is good. The surface of plastic jars is easy to print and easy to decorate, which is good for attracting customers and promoting sales.

As a new type of packaging container, plastic jars are widely used in the packaging field. It can package juice, milk powder, carbonated beverages, coffee, cosmetics, oils, etc.
