Difference between double-layer and five-layer plastic hoses and reinforced composite aluminum-plast

The hose is divided into double-layer, five-layer plastic hose and reinforced composite aluminum-plastic pipe, which are different in terms of pressure resistance, permeability resistance and hand feeling. For example, the five-layer pipe is composed of outer layer, inner layer, two adhesive layers, and another barrier layer. Features: It has excellent gas barrier performance, which can effectively prevent the infiltration of oxygen and odor gas, and prevent the leakage of the contents, fragrance and effective ingredients. The reinforced composite aluminum-plastic pipe, such as the outer plastic and the inner metal aluminum sheet, has two adhesive layers and another barrier layer. The characteristics are: the material is strong and tough, the structure is reasonable, thicker, and solid, and the compressive, cold and heat resistance are greatly improved.

2. The caliber of the hose is 16-60 pipes. When selecting a hose of a certain caliber, different capacity characteristics are marked with different lengths. The capacity of 3ml-400ml can be adjusted at will. For the sake of beauty and coordination, the caliber below 35 pipes is commonly used for 60ml, 35-45 pipe orifice diameter is usually used for 100ml and 150ml, and the caliber above 45 pipes is required for 150ml.

3. Technically, it is divided into round tube, elliptical tube, flat tube and flat tube. Flat tubes and flat tubes are more complicated than other tubes, and are also new tubes developed in recent years, so their prices are relatively expensive.

4. The hose covers have various shapes, generally including flat head cover, round head cover, high cover, lift cover, flat cover, double-layer cover, spherical cover, lipstick cover, and plastic cover, which can also be processed in a variety of processes, such as hot gilt edge, silver edge, colored cover, transparent cover, oil spray, electroplating, etc. The pointed mouth cover and lipstick cover are usually equipped with internal plugs. The hose cap is an injection molding product, and the hose is a pull tube. Boya produces the cap in its own workshop. Most hose manufacturers do not produce hose caps themselves.

5. Some products need to be filled before they are sealed. Generally, they are locked. The tail sealing can be divided into straight tail sealing, twill tail sealing, umbrella tail sealing, star point tail sealing, and irregular tail sealing. The required date code or LOGO can be pressed at the tail sealing.

6. The hose can be made of colored tubes, transparent tubes, colored or transparent frosted and pearlescent tubes, and there are matte and bright tubes. The matte looks elegant but easy to be dirty. The difference between the colored tube and the large-area printing of the tube body can be judged from the left or right bleeding position interface. If the colored strips overlap at the interface, the large-area printing tube is required to use high ink, otherwise it is easy to fall off and will crack and expose white marks after being folded.

7. The tube body can be used for 6-color offset printing, 6-color screen printing, flexographic printing and labeling. Some manufacturers have thermal transfer equipment and technology. The effect of bronzing, silvering and screen printing is better, and the effect of flexographic printing is more realistic!

There are mainly white tubes, pearlescent white tubes, color tubes, transparent tubes, glow tubes, etc; The processes include bright light, frosting, bronzing, silvering, offset printing and screen printing; The cover has turned gilt edge, silver edge, gold plating, silver plating, etc;
