Dissection of cosemtic tube packaging printing

(1) To retain the texture of special Cosmetic Tube packaging market is one after another, for example, some of the surface of Cosmetic Tube is made of modified PE material, and this kind of tube has the characteristics of SoftTouch. If using relief offset printing. After printing, polish is generally needed to improve the wear resistance of the product, but the polish covers the texture of the special tube. With the screen printing process, the wear resistance requirements can be met without polishing after printing, so the screen printing can maintain the texture of this special cosmetic tube to the maximum extent.

(2) It can meet the requirements of small batch production and screen printing with fast plate making speed and short commissioning time. Qualified products can be printed within a relatively short period of time, which meets the requirements of multi-batch and small batch printing of Cosmetic Tube. For some frequent changes to the makeup tube design, screen printing is the most suitable.

In the image of screen printing as a manual process, screen printing is not. Tube screen printers are becoming fully automatic. Front end feeding device, to UV screen printing unit. After the printing, the tube is directly packaged and fully automatic printing production is realized. Lisson Cosmetic Container Group's RUV-536 screen printing line, for example, is fully automated when printing special plastic containers (tubes are one of them) at a rate of 50 pieces/min (tubes are 75mm in diameter). Screen printing depends on its own characteristics, make up for the letterpress offset printing shortage. The two add radiance to each other, and jointly decorate the tube packaging printing market. Lisson is a cosmetic tube manufacturer with 20+ years experience in wholesale cosmetic tube supply and custom cosmetic  tube service.

This process is generally first printed on a composite sheet (mostly white) or transparent plastic film. The former mainly uses flexographic printing, and the printing method is surface printing. The latter can be used in gravure printing, printing for the inside. After printing, the composite tube is made.

1. Flexographic printing (1) line and field printing advantages obvious with the improvement of flexographic platemaking technology, flexographic printing has gradually been able to replicate some of the more complex manuscripts. At present, the printing pattern on the surface of composite makeup tube is generally dominated by lines and solid color blocks, which just play a role in flexographic printing of solid color blocks and ink evenly and evenly. Good color reproduction repeatability advantage. For fastidious customers who pay attention to brand image, flexographic printing just meets their requirements.

(2). The increasing competition in the market forces customers in the market for effective wholesale or custom cosmetic tubes to constantly innovate. The launch cycle of new products is significantly shortened, and the packaging design pattern is often changed. The trends in the consumer market have put forward higher requirements for printing manufacturers. In the face of sudden overseas orders, in the face of small batch and urgent delivery time fast printing orders, do not let the business opportunities pass flexographic printing can help printing manufacturers to seize the fleeting business opportunities.

First of all, compared with gravure plate making, flexo plate making cycle is short, shorten the production cycle. Secondly, skilled workers, operating flexographic printing machine, printing preparation time is short, can quickly print qualified products, each batch of product printing cycle is significantly shortened. Again, flexographic printing is cheaper for smaller tube parts than gravure printing. Because the production cost of photosensitive resin plate is lower than gravure plate, flexo plate is suitable for low volume composite tube printing. As a result, flexographic printing offers the advantage of easy replacement of live parts in the composite tube printing market with multi-batch and short lead times.

(3) The tensile resistance of plastic film with excellent tension control is poor. Improper tension control in the process of unwinding and printing will lead to film deformation and affect the accuracy of printing registration. Flexographic printing machines at home and abroad generally use two tension control system, the first use of magnetic powder brake to control the unwinding tension, when the unwinding tension suddenly changes, through the tension floating roll swing from side to side, offset the change in tension, to ensure that the tension in the printing JIL1 region can maintain a constant state. Some flexographic presses have a separate motor-controlled traction roll that adjusts the tension according to changes in the tension before the film enters the printing area. In the printing area, the tension control system is used to automatically compensate the loss of tension and maintain the tension within the range set by the user.

(4) Safety and environmental protection of European and American countries strict legislation, as well as people-oriented "green consumption concept. High requirements have been put forward for the safety and hygiene of food and medicine packaging. In order to ensure customer satisfaction and comply with relevant regulations and regulations of the exporting country, domestic tube packaging printing enterprises adopt safe and environmentally friendly flexographic printing process to print composite plastic sheet or film and then produce composite tube when processing orders from European and American customers. Today, the imported flexographic UV inks used by printing manufacturers have met the relevant health and safety standards. Therefore, flexographic UV printing has become the ideal way to print food and medicine composite tube packaging. And more and more cosmetic suppliers resort to manufacturing sustainable cosmetic packaging, such as sugarcane tubes,  pcr tubes, or aluminium tubes.

2. In the production of the composite Personal Care Tube, the transparent plastic film can be printed in gravure and then reprinted, cut and tubed. In this process, gravure printing mainly has the following characteristics.

(1) in the printing ink layer is not easy to wear in the first printing and then composite, tube making process, intaglio printing using the way of inside printing on the surface of transparent plastic film first printing color ink, then printing white ink, film printing and then composite. The composite beauty tube with the in-print method is not easy to wear and tear in transportation, circulation and daily use because the ink layer is covered with a thin film, so the exterior decoration effect can be maintained for a long time.

(2) Printing speed is fast. The Jill layer is mainly PE film. In the high-speed gravure printing production line, the printing speed of PE film can reach 15O ~ 200m/min. High-speed printing meets the requirements of mass composite tube printing production, such as the order of some daily chemical products, the number of tubes is up to tens of millions. Gravure printing is the preferred printing method for this type of long plate printing.

In Makeup and Tube printing, gravure printing has a slightly better effect than flexo printing. The main reason for this is that intaglio is more detailed than flexography, and it can reproduce some gradual, detailed art work. Secondly, the use of gravure printing to print transparent plastic film has been for a long time, the technology is relatively mature, the operators have also accumulated rich experience, help to control the change factors in printing, get good printing and replication effect.

(4) Green environmental protection is the future direction of development. The compound tube is used for food and medicine packaging, especially the hygiene and safety of packaging materials. Gravure printing, in order to establish itself in the compound tube printing market, must continue to improve to meet the environmental and health requirements and meet the stringent health and safety requirements of end users. At present, some of the domestic Make Container manufacturers that use gravure printing to process composite tube have passed ISO14000 environmental management system certification and OHSAS18000 occupational health and safety management system certification, which will become the development trend of composite tube gravure printing. Tube printing is an important part of Tube packaging and decoration. The quality of Tube packaging and decoration, product description and brand identification cannot be separated from printing technology. The beautiful Tube decoration makes products stand out from the fierce competition, so Tube printing cannot be underestimated.

In summary, the characteristics of the consumer market and the production process of Cosmetic Tube determine that four printing methods -- relief offset printing, screen printing, flexo printing and gravure printing -- have a foothold in the market. For wholesale makeup tube printing, for cosmetic tube manufacturer or supplier, none of the four printing methods shall be less.
