Plastic bottle packaging has been refurbished, especially in the fields of food bottles and medicine bottles, and the development of new packaging technologies is the fastest. In beverage bottles, many new packaging are presented. For example, PET/PEN plastic bottles enrich beer packaging; dual-chamber cans separate different sensitive ingredients, which greatly improves the taste of products; self-cooling/self-heating cans bring convenience to outdoor users; lightweight glass bottles plus external coating Layers are changing the cost-effectiveness of glass bottle packaging.
In cosmetic bottle packaging, plastics imitating thick-walled glass bottles, fashion perfume bottles, high-tech dispensers (cosmetic spray pump heads, cosmetic dispensing pump heads), etc. are constantly innovating. Green or ecological packaging is gradually becoming a household name.
