The advantage of plastic packaging is that it has good chemical stability. Plastics have good resistance to common acids, alkalis, salts and other media, and they are sufficiently resistant to water, oxygen, carbon dioxide and various chemicals from the packaging and the external environment of the packaging. Corrosion of the medium has a strong advantage over metals.


Excellent optical performance. Many plastic packaging materials have good transparency. All plastic packaging containers made by plastic processing manufacturers can clearly see the contents, which has a good display and promotion effect.


Considering the price, it is cheap and simple in production process, suitable for large-scale use. And it's light and easy to carry.
