Plastic jars have not been around for a long time, but they have developed very rapidly and have replaced metal jars and glass bottles on many occasions, mainly because they have many advantages:
1.Light weight. The materials used to make plastic cans have a lower density. Based on the mass of containers with the same volume, plastic jars are smaller than metal jars and glass bottles.
2.The cost is lower. Plastic jars have lower material costs and are easier to manufacture, so the overall price is cheaper.
3.Can reliably protect products. The tank body is made of a variety of materials and has good chemical stability and barrier properties; the bottom, lid and tank body are combined with 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 rarely suffer from strength damage.
5.The shelf effect is good. The surface of plastic jar is easy to print and decorate, which is great for attracting customers and promoting sales.
