As shown in fig. 2, the pulpeable aqueous resin coating 120 of the present invention can be pulped with a paper print to form a uniform mixture. As shown in fig. 3, after the paper-plastic product formed by the post-printing lamination process in the prior art is crushed, a sheet-shaped film is not crushed.
In this embodiment, the wear resistance, corona value, adhesion, gold stamping performance, leveling effect and screen printing performance of the non-plastic aqueous resin film 100 prepared in embodiments 1 to 8 are also tested. Wherein, the wear resistance can be 4 poundsUnder pressure, the coating was not scratched 400 times back and forth. Corona value of the waterborne resin coating 120 that can be pulped into a slurry is stable at 38-40 dynes as measured with a corona pen. The adhesive force performance can be quickly torn after being pasted by a 3M adhesive tape for 5 minutes, and the coating is intact. The gold stamping performance test adopts a gold stamping electric plate to be heated to 110-. The leveling effect is as follows: the coating has no stripe, no spot, no pinhole and no shadow. Screen printing performance after screen printing: the lines are not shrunk, and the 3M adhesive tape is torn, has no UV shedding, no bubbles and no pinholes. The 3M adhesive tapes are all 3M
Tape # 810.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
