We may have used cosmetics more or less, but we don't know enough about the specific ingredients and packaging materials of cosmetics. In fact, cosmetic packaging materials are mainly divided into main containers and auxiliary materials. Main containers usually include plastic bottles, glass bottles, and hoses. 1. Plastic bottle Plastic bottles are usually used for thicker caps, stoppers, etc., which have relatively strong barrier properties. For the development of this kind of mold, the use of stainless steel is more expensive than the use of alloy materials, but it will also be more durable. The specific production quantity and the choice of materials should be determined according to the demand of the production volume, and generally it is up to the customer to decide. Two, glass bottle In cosmetics, more glass bottles are used, which is inseparable from the diverse shapes, rich processing, and diversified bottle caps of the glass bottles themselves. There are two main types of glass bottles. One is a wide-mouth bottle, which is mainly used to hold solid pastes; the other is a narrow-mouth bottle, which is mainly suitable for emulsions or liquids. Three, hose The hose is mainly divided into single-layer, double-layer, and five-layer, of which double-layer pipes are the most commonly used. When a hose of a certain caliber is selected, different lengths represent different capacity characteristics and have different effects. Compared with the other two types of containers, the hose has better gas barrier properties, can effectively prevent oxygen and other odors from entering it, and ensure good air tightness.
