Laminated tube is the Angle of the two substances of their respective advantages, framed composite hoses, make it has the advantages of both the hose, such as laminated hose by aluminum foil and plastic film, it has the advantages of wet resistance, weather resistance, can be printed and laminated, first make the graphic in the plastic film layer, and it's beautiful appearance, at the same time can also be printed after processing and molding, changed the way of printing, surface after molding first, so that you can use camera plastic in aluminium laminated tube the form of gravure printing, after laminated, forming into laminated tubes. Plastic hose printing plastic printing ink adhesion is poor, need to surface treatment before printing. Now using thermal transfer printing method abroad, will be made to print the graphic transfer paper (i.e., kraft paper, coated with a coating), color sequence is instead of color printing color sequence, then under the printing surface coating a layer of the heat treatment can produce adhesion material, then will be printed by the contact surface with a transfer paper, heat transfer under the hot pressing.
Cosmetics hose diameter have a variety of caliber, elected a certain diameter of the hose, the capacity of different characteristics in different length, capacity of 3 ml - 360 - m can be adjusted in order to beautiful coordination, the calibre of the commonly used below 35 # below 60 ml, 100 ml, 150 m usually use 45 # 35 # - caliber, more than 150 ml capacity is more than 45 #. Production pump tube process, the circular tube, oval tube, oblate tube, flat pipe are common. Hose cover shape, generally can be divided into flat cover, round epicranium, high cover, lift the lid, super flat cover, double deck lid, spherical cover, paste cover. Sealing side, mainly has straight grain and sealing, twill and sealing, and sealing type, star sealing, sealing, of course, the production date, etc., and we see everyday basically appears in sealing color appearance, can do color tube, transparent tube, transparent frosted, bead light pipe. In addition, there exists a dumb light cosmetics hoses and light, elegant matte seemingly but easy dirty. For white tail slit, large printing, use the ink demand is high, otherwise easy peeling and cracking after folding and white mark.
Hose rotation after a week, that is, from the rubber roller, the hose printing overprint work come to an end, with infrared irradiation, then to make imprinted dry quickly and to increase the brightness of imprinting. Toothpaste hose, hose shoe empty lotion tubes polish and medicinal ointment hose printing in this way. Metal hose printing ink, besides should have heat resistance, light fastness, also because the hose is in use when squeezing and twists and turns, also often meet with water and moisture, so the ink should be able to meet the above conditions. Within the hose material is different, ink must also can resist erosion of these material.
