The main containers usually include plastic bottles, glass bottles, flexible tubes, and vacuum bottles. Take the packaging hoses and plastic bottles of cosmetic packaging bottles, for example, the hose caps have various shapes, generally divided into flat caps, round caps, high caps, flip caps, ultra-flat caps, double-layer caps, spherical caps, lipstick caps, The plastic cover can also be processed in a variety of processes, such as bronzing edge, silver edge, colored cover, transparent, oil injection, electroplating, etc. The tip cap and lipstick cover are usually equipped with an inner plug.

   The hose is divided into single-layer, double-layer, and five-layer hose, which are different in terms of pressure resistance, penetration resistance, and hand feeling. For example, the five-layer tube consists of an outer layer, an inner layer, two adhesive layers, and another barrier layer. . Features: It has excellent gas barrier properties, which can effectively prevent the infiltration of oxidation and peculiar gases, and at the same time prevent the exudation of the content's fragrance and active ingredients.

   Double-layer hoses are more commonly used, and single-layer hoses can also be used for medium and low-grade hoses. Flat tubes and ultra-flat tubes are more complicated than other tubes, and they are also new types of tubes in recent years, so the price is correspondingly more expensive.

    The materials of plastic bottles are usually PP, PE, ABS, ABS, acrylic, PET, and so on. Among them, PET material is an environmentally friendly material, which has high barrier properties, lightweight, non-breaking properties, chemical resistance, and strong transparency. It can be made into pearlescent, colored, magnetic white, and transparent. The acrylic material is an injection-molded bottle, which has poor chemical resistance. Generally, the paste cannot be directly filled. It needs to be equipped with an inner tank to block it. The filling should not be too full to prevent the paste from entering between the inner tank and the acrylic bottle, so as to avoid cracks. Packaging requirements are high during transportation, because it looks particularly obvious after scratches, has high permeability, and has a thick upper wall, but the price is quite expensive. AS has better transparency, ABS has better toughness, and the chemical properties of different materials are different.
