Description

technical field [0001] The invention relates to the technical field of PP plastic bottles, in particular to an environment-friendly PP plastic bottle. Background technique [0002] PP plastic, also known as polypropylene, is a thermoplastic resin made by the polymerization of propylene. It is divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene according to the arrangement of methyl groups. PP plastic bottles belong to PP plastics. One of the most popular products, due to the low cost of plastic bottles, convenient production, and high recycling value, it is widely popularized in daily life. However, due to the low cost of plastic bottles, the modern manufacturing industry has less functional development of plastic bottles, resulting in a lack of functional value for plastic bottles. The overall structure of plastic bottles cannot be adjusted to a large extent. The inner space is single, and the effect of classifying water ...
