Knowledge of cosmetic packaging materials

As more and more operators recognize the cosmetic OEM model, cosmetic OEM has gradually become the main productivity of my country's cosmetics manufacturing industry. However, many operators do not know much about the professional knowledge of the cosmetics foundry industry, especially the packaging materials of the foundry products. Because many operators do not know the cosmetics packaging materials, it is more difficult to communicate with the foundries. Strenuous. Let me introduce to you the types, uses and printing methods of cosmetic oem ??packaging materials.

At present, cosmetic oem ??packaging materials are mainly divided into three categories: glass bottles, makeup tube , and plastic bottles. Among them, glass bottle product packaging materials are mainly used for skin care products (creams, lotions), perfumes, essential oils, and nail polishes. For products with smaller capacity, cosmetics with a capacity larger than 200ml are rarely used. The printing methods used are mainly silk printing and bronzing. (It is best not to exceed 2 times of silk screen and hot stamping together. Too much color registration, high defective products and high cost)

makeup tube are divided into single-layer, double-layer, and five-layer makeup tubes, which are different in terms of pressure resistance, anti-permeability, and hand feel. For example, a five-layer makeup tube bottle consists of an outer layer, an inner layer, and two layers. The adhesive layer and the barrier layer are composed of excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and odorous gases, and at the same time prevent the leakage of the content fragrance and effective ingredients. Therefore, it is more suitable for use in cosmetics such as liquid and emulsion. In addition, in terms of printing, makeup tube are mainly used to directly produce plastic products with color, colored and multi-purpose, and some are transparent, which is less used. It can also be printed by silk screen printing.

Plastic bottles are usually made of PP, PE, K material, AS, ABS, acrylic, PET, etc. Usually used in cosmetics containers with thicker walls, cream bottles, bottle caps, stoppers, gaskets, pump heads, and dust covers are injection molded; PET blow molding is two-step molding, tube embryo is injection molding, and finished packaging is blown bottle. Others, such as lotion bottles and washing bottles with thin container walls, are blown bottles. The production process is mainly made of PP and ABS bottles with solid colors, PETG materials and acrylic bottles mostly use transparent colors, with a sense of transparency, acrylic bottle walls are mostly spray-colored, which can refract light and have a good effect. The printing method can be silk screen, hot stamping, hot silver and other methods.
