A must-read for cosmetics professionals（2）

Hoses are classified into single-layer, double-layer and five-layer hoses, which differ in terms of pressure resistance, water resistance and hand feel. For instance, a five-layer hose consists of an outer layer, an inner layer, two adhesive layers and a barrier layer. Features: It has excellent gas barrier performance, effectively preventing the infiltration of oxygen and odorous gases, while also preventing the leakage of the fragrance and active ingredients of the contents.

2. Double-layer pipes are more commonly used. For medium and low-end ones, single-layer pipes can also be used. The hose diameters range from 13# to 60#. When choosing a hose of a certain diameter, different capacities are marked with different lengths. The capacity can be adjusted from 3ml to 360ml. For aesthetic coordination, for 60ml or less, diameters of 35# or less are commonly used. For 100ml and 150ml, 35# - 45# diameters are usually used. For capacities larger than 150ml, 45# or larger diameters are required.

3. In terms of process, they are classified into round tubes, oval tubes, flat tubes and ultra-flat tubes. Flat tubes and ultra-flat tubes have more complex manufacturing processes than other types of tubes and are also new types of tubes that have emerged in recent years, so their prices are correspondingly higher.

4. The shapes of hose caps are diverse, generally including 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 various ways, such as gold foil stamping, silver foil stamping, colored caps, transparent, oil spraying, electroplating, etc. Pointed caps and lipstick caps usually come with inner stoppers. The hose cap is an injection-molded product, and the hose is a drawn tube. Most hose manufacturers do not produce hose caps themselves.

5. Some products need to be sealed at the end after filling. Sealing at the end can be roughly divided into: straight line sealing at the end, diagonal sealing at the end, umbrella sealing at the end, star dot sealing at the end, and irregular sealing at the end. When sealing at the end, you can request to print the required date code at the sealing position.

6. Hoses can be made into colored tubes, transparent tubes, colored or transparent frosted tubes, pearlescent tubes, and are also available in matte and glossy finishes. Matte ones may seem elegant but are prone to dirt. The difference between colored tubes and those with large-area printing on the tube body can be judged from the cut at the tail. If the cut is white, it is a large-area printed tube, and the ink used has high requirements; otherwise, it is prone to fall off and will crack and show white marks after being folded.

7. The production cycle of hoses is generally 15 to 20 days (counting from the confirmation of sample tubes). The order quantity for a single item is 5,000 to 10,000. For large-scale manufacturers, the minimum order quantity is usually 10,000. For very few small manufacturers with a wide variety of products, a minimum order quantity of 3,000 for a single item is also acceptable. Few customers make their own molds. The vast majority are public molds (a few special LIDS are private molds). There is a ±10% deviation between the contracted quantity and the actual supply quantity in this industry.

8. There are significant price differences among hoses due to their quality and manufacturers. The plate-making fee is usually between 200 and 300 yuan per color. The hose body can be printed in multiple colors and silk-screened. Some manufacturers have heat transfer printing equipment and technology. Gold and silver hot stamping are calculated based on the unit price of the area. Screen printing has a better effect, but it is more expensive and there are fewer manufacturers. Different manufacturers should be chosen according to different levels of needs.
