In terms of packaging containers, glass bottles were originally used for packaging beverages, followed by paper composite cans, and then PET bottles. Now rigid PET bottles have become the largest packaging material for carbonated and non-carbonated beverages, which accounted for 26.5% of beverage packaging containers, glass bottles have dropped from 28.9% in 1981 to 19.5%, and aluminum cans account for 39%. And plastic bottles are growing rapidly at an annual growth rate of more than 3%. To be sure, even in the countries where the plastic packaging industry has been most criticized. Plastics will continue to develop at a much faster rate than other packaging materials, because many of the characteristics of plastics cannot be replaced by any other packaging materials. While occupying the field of sales and packaging, the plastic packaging industry has already developed into transport packaging, which will eventually force the “transportation packaging” which is still mainly metal to be replaced by plastics.
