The utility model provides an environment-friendly paper holder with a waterproof effect for packaging, referring to fig. 1-3, the environment-friendly paper holder comprises a paper holder main body 1, the paper holder main body 1 comprises an upper paper holder 101 and a lower paper holder 102 which are stacked up and down, the bottom end of the lower paper holder 102 is covered with a waterproof film 3, a plurality of memory metal filaments 2 which are uniformly distributed are clamped between the upper paper holder 101 and the lower paper holder 102, the memory metal filaments 2 are in a bending structure in the paper holder main body 1, and the outer end walls of the memory metal filaments 2 are coated with nontoxic hydrothermal paint.

Further, referring to fig. 1-3, the upper paper support 101 and the lower paper support 102 are sealed by a hot pressing process, the memory metal filament 2 and the lower paper support 102 are connected by adhesive bonding, and the memory metal filament 2 is not only placed between the upper paper support 101 and the lower paper support 102, but also bonded with the lower paper support 102 by adhesive bonding, so as to ensure that the memory metal filament 2 can smoothly drive the lower paper support 102 and the waterproof film 3 to synchronously move in the heat shrinkage process, and the break is smoothly closed.

Further, referring to fig. 3, the adhesive is applied in the sequence that before the non-toxic hydrothermal material is coated on the memory metal filament 2, the non-toxic hydrothermal material is coated on the memory metal filament 2 only after the adhesive is solidified and the memory metal filament 2 and the lower paper support 102 are smoothly adhered together, so that the possibility of occurrence of a reaction caused by water distribution in the non-toxic hydrothermal material and the adhesive is avoided.

Further, referring to fig. 1 to 3, the thickness of the double-layered paper holder main body 1 formed by the upper layer paper holder 101 and the lower layer paper holder 102 is the same as that of the original single-layered paper holder main body 1, so that excessive cost increase is avoided.

Further, referring to fig. 3, the memory metal filament 2 may be used only at the inner bottom end of the lower paper holder 102, but not at the inner side wall of the lower paper holder 102, because the inner bottom of the lower paper holder 102 is always in contact with the outside most and is most easily scratched during daily use, and the part with the largest bearing pressure needs to be protected by the memory metal filament 2 when the paper holder main body 1 is lifted with the bearing content therein, thereby further reducing the production cost of the product.
