Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.
[0026] like Figure 1 As shown, the present application provides a multi-layer overprinted packaging paper, including packaging paper, the packaging paper having a first base layer 1 and a second base layer 12, an adhesive layer 11 is arranged between the first base layer 1 and the second base layer 12, so that the first base layer 1 and the second base layer 12 can be bonded by the adhesive layer 11, wherein the first base layer 1 and the second base layer 12 are made of the same material, both of which are composed of wood fibers, so that the first base layer 1 and the second base layer 12 have good strength and durability, and also have a certain buffering and shock absorbing effect;
[0027] At the same time, the adhesive layer 11 is used to fix the first base layer 1 and the second base layer 12. The adhesive layer 11 can be made of water-based white glue, the main component of which is latex. At the same time, the water-based white glue has good adhesive properties and water resistance;
[0028] In order to improve the overall stability of the wrapping paper, the wrapping paper is based on the first base layer 1 and the second base layer 12, respectively, so as to provide additional support and protection for the wrapping paper, and also help to increase the strength and durability of the wrapping paper;
[0029] In order to improve the thermal insulation of the packaging paper, a thermal insulation layer 13 is provided on the second base layer 12, and the internal material of the thermal insulation layer 13 can be composed of a ceramic fiber material, which is specifically made of inorganic substances such as alumina and silica, and has high temperature resistance, excellent thermal insulation performance and chemical stability;
