Tube+outer cover/tube is often made of PE plastic. According to the thickness of the product, it is divided into single-layer pipe (mostly used, lower cost) and double-layer pipe (good sealing performance). According to the shape of the product, it is divided into round tubes (mostly used, lower cost), flat tubes, also known as special-shaped tubes (requires secondary joints, higher cost). The outer cover of the tube is often equipped with screw cap (single layer and double layer, the double-layer outer cover is mostly electroplated cap to increase the product grade, which looks more beautiful, and the screw cap is mostly used for professional lines) and flip cover.
Tube body: direct production of plastic products with added colors, colored and multi-purpose, and some are transparent, which is less used.
Printing: screen printing (using spot colors, small and few color blocks, the same as the printing method of plastic bottles, requiring color registration, commonly used in professional line products) and offset printing (similar to paper printing, large color blocks and many colors, daily chemical Line products are commonly used.) There are bronzing and silver bronzing.
