How to better choose plastic packaging bottles?

Different material production plant plastic bottles due to the raw materials themselves product characteristics determine the characteristics of their plastic bottle packaging products, below we will analyze the advantages and disadvantages of different plastic bottles from the difference in raw material use, so as to analyze the most suitable product packaging, correctly choose the right plastic bottle packaging, not only can save packaging costs, but also effectively avoid a lot of unnecessary trouble.

Advantages of PET polyester bottle: good dimensional stability, strong ring stiffness of the bottle body, good chemical resistance stability, resistance to weak acids and alcohols and other solvents. Insufficient: not resistant to high temperature, easy to deform during summer transportation, not resistant to dimethylamide (DMF) solvents, not resistant to strong acids and alkalis, not resistant to concentrated acids and alkalis and phenols; PE bottles can not block some organic solvents; Multi-layer co-extrusion high-barrier bottles are relatively widespread, for example, containing pesticides containing xylene and acid emulsions or alcohols, multi-layer co-extrusion bottles should be used, because PA and EVOH are not resistant to acids and alcohols. PA or EVOH should be placed in the middle layer, and the memory should take HDPE with better acid and alcohol resistance, if there is a flat phenomenon, and increase the thickness of the bottle body, increase the stiffener, reduce the diameter of the bottle body, reduce the volume of the full mouth, you can effectively avoid the occurrence of the bottle phenomenon.
