Detailed description of cosmetic outer packaging hose material

Before understanding the detailed functions of cosmetic outer packaging hose materials, what we need to know is that cosmetic packaging materials are divided into main containers and auxiliary materials. The main container usually includes plastic bottles, glass bottles, hoses and airless bottles. Auxiliary materials are usually color box, first box, middle box. The following is an introduction to the hose. The hose can be divided into single-layer, double-layer and five-layer hoses, and their pressure resistance, permeability resistance and feel are different. For example, a five-layer tube consists of an outer layer, an inner layer, two adhesive layers and a barrier layer. It is characterized by excellent gas barrier properties, which can effectively prevent the permeation of oxygen and odorous gases, and prevent the leakage of contents, flavors and active ingredients. Double-layer pipes are more commonly used, and they can also be used as single-layer pipes if they belong to the middle and low grade. The diameter of the hose is #-#. When choosing a hose with a certain diameter, different capacity characteristics will mark different lengths. .Hose is divided into round tube, oval tube, flat tube and super flat tube in process. The processing of flat tubes and super flat tubes is more complicated than other tubes. This is also a new type of tube produced in recent years, so the price is relatively expensive. There are various shapes of hose caps, generally divided into round caps, high caps, lipstick caps, flat caps, super flat caps, lifting caps, double caps, etc. They can also be processed into various types of silver edges during processing. , Hot gold edge, transparent, etc., and the tip cap and lipstick cap are usually equipped with inner plugs. Hose caps for injection molding, hoses for drawing tubes, it should be noted that most hose manufacturers do not produce hose caps. Some products need to be sealed after filling. Tail seals can be divided into linear seals, diagonal seals, umbrella seals, star point seals and special-shaped seals. The hose can be used as a colored tube, transparent tube, colored or transparent frosted tube, etc. and there is a difference between non-gloss and bright light. The production cycle of the hose is usually-day (from the confirmation of the sample tube). Few customers open the mold themselves. Most are public molds (some special coverings are private molds). The quality of hoses and prices vary greatly between manufacturers. Therefore, different manufacturers should be selected according to different demand levels.
