1. The hose is divided into single-layer, double-layer, and five-layer hoses, which are different in terms of pressure resistance, anti-permeability, and hand feel. For example, the five-layer tube consists of an outer layer, an inner layer, and two adhesive layers. Barrier layer. Features: It has excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and peculiar gas, and prevent the leakage of the content fragrance and effective ingredients.
2. Double-layer pipes are more commonly used. Single-layer pipes can be used for medium and low-grade pipes. The diameter of the hose is 13#—60#. When a hose of a certain diameter is selected, different lengths are used to indicate different capacity characteristics. , The volume can be adjusted from 3ml to 360ml. In order to be beautiful and coordinated, the diameter below 60ml is commonly used below 35#, 100ml, 150ml usually use 35#—45#, and the volume above 150ml needs to use 45# or above.
3. In terms of technology, it is divided into round tube, oval tube, flat tube, and super flat tube. Flat tubes and super flat tubes are more complicated than other tubes. They are also new types of tubes in recent years, so the price is correspondingly more expensive.
4. The hose can be made of colored tubes, transparent tubes, colored or transparent frosted, pearlescent tubes, and there are matte and bright points. The matte looks elegant but easy to get dirty. The difference between colored tubes and large-area printing on the tube body can be Judging from the cut at the tail, the white cut is a large-area printing tube, and the ink used is demanding, otherwise, it will easily fall off and will crack and expose white marks after being folded.
