At present, cosmetic packaging materials are mainly divided into three categories: glass bottles, hose bottles and plastic bottles. Among them, glass bottle products are mainly used for skin care products (cream, lotion), perfume, essential oil and nail polish, which are small capacity products. Cosmetics that are larger than 200ml capacity are seldom used.
The printing methods used are mainly screen printing and bronzing. (the number of times of silk screen printing and bronzing should not exceed 2 in total, too many colors, high quality and high cost) the hose bottle is divided into single-layer, double-layer and five layer hoses, which are different in terms of pressure resistance, permeability resistance and hand feel. For example, the five layer hose bottle is composed of outer layer, inner layer, two adhesive layers and barrier layer, which has excellent gas barrier performance and can effectively prevent gas barrier Prevent the infiltration of oxygen and peculiar smell gas, and prevent the exudation of the fragrance and effective ingredients of the content.
Therefore, it is more suitable for cosmetics such as liquid and emulsion. In addition, the hose bottle is mainly used to add color to the plastic products directly in printing, which is multi-color, transparent and less used. It can also be printed by screen printing.
