How to print cosmetic tube

The overprinting work of graphics and text is not realized like traditional printing on the embossed paper. but the imprints on the three printing plate cylinders which are overprinted on the rubber quilt at the same time (because the imprints are solid, the overprints are combined No overlap), and then transfer the three-color ink print to the tube on the embossing roller at a time. The impression roller on the impression cylinder is covered with a tube, but it does not rotate by itself. Only after contact with the squeegee,can it rotate at the same linear speed as the squeegee.The diameter of the impression cylinder is the same as the diameter of the squeegee.. But the operation is different, the blanket cylinder rotates once,and the impression cylinder rotates 90° to complete the printingof a tube.
After the Cosmetic Tube rotates once,it will be separated from the rubber cylinder and the overprinting work of the tube printing has come to an end. Then it is irradiated with infrared rays to quickly dry the print and increase the brightness of the print Toothpaste tubes, tubes, shoe polish and medical ointment tubes are printed in this way
The printing ink for metal tubes should not only have heat resistance and light resistance,but also because the tube will encounter squeezing and tortuouswhen in use, but also often encounter water and humidity, so the ink should also meet the above conditions. The materials in the tube are different, and the inkmust also be able to resist the erosion of these materials.

Laminated tube is a tube that utilizes the respective advantages of two materials and is laminated to a synthetic tube to make it have the advantages of both For example. a laminated tube made of aluminum foil and plastic film has the advantages of moisture resistance and weather resistance.. It can be printed and then laminated, so that the graphics and text are in the plastic film layer and the appearance is very beautiful.At the same time, it can be processed and formed after printing. and the method of first forming and then curved printing is changed, so that it can be carried out by photogravure Plastic printing laminating and forming into a laminated tube.
Because of the poor adhesion of plastic ink in the printing of cosmetic tube tubes surface treatment is required for printing.At present, the hot press transfer method is used in foreign countries to print pictures and texts on transfer paper (that is, coated kraft paper),the color sequence is the opposite color sequence of color printing. and then a layer of heat treatment is applied on the printing surface substances that can produce adhesion, and then the transfer paper with graphics and text is contacted with the curved surface, and the transfer is carried out under heat and pressure.
