Tubes are a very widely used cosmetic packaging material in cosmetic packaging, among which products such as facial cleanser and facial cleanser are used the most, and other skin care products such as BB cream and gel are also used. Plastic Products Co., Ltd will popularize the knowledge of hoses for everyone.
 
1. The hose is divided into single-layer, double-layer and five-layer hose, which are different in terms of pressure resistance, anti-penetration 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 oxygen and peculiar gases, and at the same time prevent the exudation of the fragrance and active ingredients of the contents.

2. Double-layer pipes are more commonly used, and single-layer pipes can also be used for medium and low-grade pipes. The diameter of the hose is 13#-60#. When a certain diameter hose is selected, different capacity characteristics are marked with different lengths. , The capacity can be adjusted from 3ml to 360ml. For the sake of beauty and coordination, the caliber below 60ml is commonly used below 35#, the caliber below 35# is usually used for 100ml and 150ml, and the caliber above 45# is required for capacity above 150ml.
​​
3. The process is divided into round tube, oval tube, flat tube and ultra-flat tube. Flat tube and ultra-flat tube are more complicated than other tubes, and they are also new types of tubes in recent years, so the price is correspondingly more expensive.
​​
4. There are various shapes of hose caps, generally divided into flat caps, round caps, high caps, flip caps, ultra-flat caps, double-layer caps, spherical caps, lipstick caps, and plastic caps can also be processed in a variety of processes, bronzing Edge, silver edge, colored cap, transparent, oil spray, electroplating, etc., tip cap and lipstick cap are usually equipped with inner plug. The hose cover is an injection molded product, and the hose is a pull tube. Most hose manufacturers do not produce hose covers themselves.

5. Some products need to be filled before sealing. The sealing can be divided into: straight sealing, twill sealing, umbrella sealing, star point sealing and special-shaped sealing. Print the desired date code at the end.
​​
6. The hose can be made of colored tube, transparent tube, colored or transparent frosted, pearlescent tube, and there are matte and bright points. Matte looks elegant but easy to get dirty. Judging from the incision at the tail, the white incision is a large-area printing tube, and the ink used is required to be high, otherwise it will easily fall off and will crack and reveal white marks after being folded.
​​
7. The hose production cycle is generally 15 days to 20 days (from the time of confirming the sample tube). The order quantity for a single product is 5,000-10,000. The large-scale manufacturers usually order 10,000. If the manufacturer has many varieties, the minimum order quantity of 3,000 can be calculated for a single product. Few customers make their own molds. Most of them are public molds (a few characteristic covers are private molds). The contracted order quantity and the actual supply quantity, There is a ±10% deviation in this industry.
​​
8. There is a big difference in the price of the hose quality and the manufacturer. The plate making fee is usually 200 yuan to 300 yuan for the color. The tube body can be used for multi-color printing and silk screen printing. Some manufacturers have thermal transfer equipment and technology. Hot stamping and hot silver are calculated based on the unit price of the area. The screen printing effect is better, the cost is more expensive and there are fewer manufacturers. Different manufacturers should be selected according to the needs of different levels.

9. Combination form:
A: The hose + outer cover/hose is often made of PE plastic.
According to the thickness of the product, it is divided into single-layer tube (mostly used, lower cost) and double-layer tube (good sealing performance). According to the shape of the product, it is divided into round hose (mostly used, lower cost), flat hose, also known as special-shaped tube (requires secondary joint, higher cost). The outer cover of the hose is usually equipped with a screw cap (single-layer and double-layer, and the double-layer outer cover is mostly an electroplated cover to increase the product grade, which looks more beautiful, and the professional line mostly uses a screw cap) and a flip cover.
B: Production process:
Bottle body: direct production of plastic products to add color, color is multi-purpose, and some are transparent, which is less used.
Printing: silk screen printing (spot color, small and few color blocks, the same as plastic bottle printing, need to register color, commonly used in professional line products) and offset printing (similar to paper printing, with large color blocks and many colors, daily chemical Line products are commonly used.), as well as hot stamping and hot silver.
