Plastic jans have not been around for a long time, but they have developed very rapidly. Metal cans and glass bottles have been replaced in many cases, mainly because of its many advantages:
1 light weight. The material density of the plastic cans is small, and the plastic cans are smaller than the metal cans and glass bottles in terms of the same volume of the containers.
2 the cost is lower. Plastic jans have lower material costs and are easier to manufacture, so the overall price is cheaper.
3 can reliably protect the product. The can body is made of a variety of materials and has good chemical stability and barrier properties; the bottom, the cover and the can body are combined with a reliable sealing structure, so that the contents can be reliably protected.
4 mechanical strength is better. Although the mechanical properties of plastic cans are slightly lower than that of metal cans and glass bottles, they are sufficient for packaging general products, and there is little problem of strength damage.
5 shelf effect is good. The surface of the plastic can is easy to print and easy to decorate, which is good for attracting customers and promoting sales.
There are also some shortcomings in plastic cans: for example, the sealing quality of the bottom cover and the can body is not stable; when vacuum packaging and pressure packaging are performed, the strength of the can body is sometimes not high enough.
As a new type of packaging container, plastic cans are widely used in the packaging field. They can package juice, milk powder, carbonated beverages, coffee, cosmetics, oils, etc.
