2021-10-06

Most of the wholesale cosmetic tubes processes used by Cosmetic Tube Manufacturers are offset printing, screen printing and hot embossing.

Common cosmetic tube printing processes are: dust removal - surface pretreatment - printing (UV ink) - glass varnish UV curing. A dedicated cosmetic tube printer can do much of these on the follow.

Cosmetic tube production process -- dust removal:

A common problem with plastic materials is that they are relatively prone to static electricity. During production of the tube, the raw material rubs against the metal mould, creating static electricity on the surface of the custom cosmetic tube, which makes it prone to dust absorption. Therefore, dust removal is required during printing.

Cosmetic tube manufacturing process -- Surface pretreatment:

As the polyethylene raw material is a non-polar material, surface pretreatment is required prior to printing. Cosmetic Tube Manufacturers has two main treatment methods, one is corona treatment and the other is flame treatment. Both of these methods can achieve the purpose of making ink and varnish firmly bonded.

Production process of Custom Cosmetic tube -- Printing:

Tube of All Cosmetic Tube Manufacturers currently have two commonly used printing methods from cosmetic tube manufacturers. One is offset printing. The ink is transferred to the printing plate by a set of rollers, and the printing plate transfers the ink from the printed pattern to the blanket. The blanket then transfers the entire print pattern to the substrate at one time.

Offset printing plates are usually made from photocured resin plate materials that are made through major exposure, development, cleaning, drying and post exposure processes. The production time for cosmetic Tube Suppliers is about 30-40 minutes and the printing durability can reach more than 100,000.

Nowadays, offset printing from Cosmetic Tube Factories can run at up to 12,000 per hour and the process has become much easier and simpler. Offset printing is widely used in tubular printing due to the increase of production speed and the reduction of cost.

Another method of custom cosmetic tube printing by cosmetic tube suppliers is traditional screen printing. In recent years, the printing accuracy and printing speed of household screen printing machine have been greatly improved. Bulk Custom Wholesale cosmetic tubes production speed can reach 5000 / hour, overprint accuracy can reach ±0.2mm. Because of the thick ink layer of screen printing, it is mainly used for color. Print tube or part of uncovered varnish product.

Cosmetic tube production process -- Coating:

A coating device consisting of two steel rollers and one rubber roller is installed on the offset press. Adhesion fastness of varnish is also directly related to the surface tension of pretreated plastic. Varnishes are usually UV-curable varnishes and come in many types, such as gloss and matte oils. In addition, there are thermosetting varnishes and three-in-one varnishes used after offset printing.

Cosmetic tube production process -- varnish curing:

For UV curing varnish, the degree of curing varnish and UV lamp issued by the wavelength and UV intensity has a great relationship. For products that undergo subsequent processing (e.g., hot stamping), the degree of curing of the varnish will have a significant impact on the quality of subsequent processing.

From Cosmetic Tube Manufacturers, a thin layer of hot-pressed paper is pressed on it so that the silk screen will not feel uneven. The hot stamping process is mainly divided into several parts: the preparation of hot stamping, hot stamping plate, plate installation, the determination of hot stamping process parameters, hot stamping test and formal hot stamping.

The role of cosmetic tube in cosmetic packaging

As the competition in the cosmetics market becomes more and more fierce, the cosmetic tube suppliers are making great efforts to expand the sales share of their products in the packaging and promotion of cosmetics.

Cosmetic tube packaging is not only a container, but also a fashion product, which needs varied shapes and rich colors. For now, glass and plastic have the edge. With the continuous development of glass production technology and the mature application of printing, hot stamping, frosting, dyeing, glazing and other technologies, the fashion potential of glass packaging has been fully tapped. And because it is easy to form and has colorful colors, plastic cosmetic tubes have always been the expert in creating fashion. Today's plastics mimic glossy glass perfectly. Besides, there are cosmetic sustainable packaging developed by eco friendly cosmetic packaging suppliers to meet needs of sustainable cosmetic packaging. PCR cosmetic packaging, sugarcane cosmetic packaging are most popular among all wholesale custom biodegradable cosmetic containers.

Cosmetic tube is an essential part of cosmetic packaging. Function of cosmetic tube in cosmetic packaging:
1, eliminate part of the air (oxygen) in the packaging container, can effectively prevent the deterioration of cosmetics.
2, the use of barrier (air tightness) good packaging materials and strict sealing technology and requirements, can effectively prevent the exchange of packaging content material, can avoid cosmetic weight loss, deterioration, and can prevent secondary pollution.
3. The gas inside the container has been removed, which accelerates the conduction of heat, which can improve the efficiency of hot sterilization, and avoid the rupture of the packaging container due to the expansion of gas when heating and sterilization.
In the food industry, bulk cosmetic tube application is very common, all kinds of cooked products such as chicken legs, ham, sausage, etc. Salted products such as pickles, bean products, preserved fruits and other foods that need to keep fresh are increasingly using cosmetic tubes. The shelf life of food packaged by cosmetic tube greatly extends the shelf life of food. Therefore not only do cosmetic tube manufacturers work for cosmetics company but also they provide food company with food-grade cosmetic tubes.
