Screen printing: The printed result has obvious concave-convex feeling because it is a layer of ink. The cylindrical bottle printed by screen printing can be completed in one go, while irregular shapes require separate fees. Colors also require separate fees. Screen printing ink can be divided into self-drying ink and UV ink. Self-drying ink is prone to peeling off in the long term and can be wiped with alcohol. UV ink has obvious concave-convex feeling and is difficult to wipe off.
Hot stamping: A thin layer of paper is stamped on the surface, so there is no concave-convex feeling as in screen printing. Hot stamping is not recommended directly on the two materials of PE and PP. First, heat transfer printing should be performed before hot stamping. Alternatively, high-quality hot stamping paper can be directly used for hot stamping. Hot stamping cannot be done on aluminum-plastic, but can be done on full-speed lines.
Water transfer printing: It is an irregular printing process performed in water, and the printed patterns are inconsistent. The price is higher.
Heat transfer printing: It is mostly used for products with large quantities and complex printing. A film is attached to the surface, and the price is relatively high.
Offset printing: Mostly used for aluminum-plastic and all-plastic tubes. If offset printing is used for white color on colored tubes, screen printing must be used, or the base color will show through. Sometimes a layer of glossy film or matt film is added to the surface of the tube.
