Advances in Polyethylene Terephthalate Beverage Bottle Optimization: A Mini Review

Compared with other materials, polyethylene terephthalate (PET) has high transparency, excellent physical and mechanical properties in a wide temperature range and good hygiene and safety, so it is widely used in the packaging industry, especially in the packaging of beverages and foods. The optimization of PET bottles is mainly reflected in three aspects: material optimization, structure optimization and process optimization, among which there is much research on material optimization and process optimization, but there is no complete overview on structure optimization. A summary of structural optimization is necessary. Aiming at structural optimization, the finite element method is a useful supplement to the beverage packaging industry. By combining the computer-aided design technology and using finite element software for finite element simulation, researchers can replace the experimental test in the pre-research design stage, predict the effect and save cost. This review summarizes the development of PET bottles for beverage packaging, summarizes various optimization methods for preventing stress cracking in beverage packaging, and especially focuses on comparing and evaluating the effects of several optimization methods for packaging structure. Finally, the future development of all kinds of optimization based on structural optimization in the field of beverage packaging is comprehensively discussed, including personalized design, the combination of various methods and the introduction of actual impact factor calculation.

Automated summary

Compared with other materials, polyethylene terephthalate (PET) is widely used in the packaging industry due to its high transparency, excellent physical and mechanical properties, as well as good hygiene and safety. However, there is still a lack of complete overview on structure optimization in PET bottle optimization. The finite element method, as a useful supplement, can predict the effect and save cost in the pre-research design stage by combining computer-aided design technology and finite element software. This review summarizes the development of PET bottles for beverage packaging, evaluates various optimization methods for packaging structure, and discusses the future development based on structural optimization.
