Embodiment Construction
[0013] The pretreatment method of the film post-it note of the present invention will be specifically described below in conjunction with specific embodiments.
[0014] The pretreatment method of the film type post-it note of the present invention comprises the following process steps:
[0015] 1) Prepare roll film, adhesion promoter, silicone oil, release agent, oily ink, solvent;
[0016] 2) Open the roll film, use the gravure printing machine with gravure printing rollers, according to the dosage of 1.9-3.5 grams of adhesion promoter and 2.5-4.6 grams of solvent per square meter at the first set of gravure printing rollers, to the opposite side of the roll film Print, then dry, and make an adhesive coating on the reverse side. The gravure printing roller used is provided with cells. The shape of the cells is circular, rhombus, hexagonal or nonagonal. The depth of the cells is It is 5-9dmm, and the network cable is 150-230 lines per inch.
[0017] 3) The reel film obtained...

The invention discloses a pretreatment method for a film sticky note. The method comprises the following technological steps that a gravure printing machine provided with a gravure printing roller is used for conducting printing and drying on the back surface of a rolled film with adhesion promoters of 1.9-3.5 g per square meter and solvents of 2.5-4.6 g per square meter, and an adhesive coating is manufactured; and then the front surface of the rolled film is printed and dried, an isolation layer is manufactured on the front surface of the rolled film, and special printing of the rolled film is completed. According to the pretreatment method for the film sticky note, the unique technological steps are adopted, and the specific gravure printing machine provided with the gravure printing roller is utilized; through unique selection to shapes, depths and mesh lines of ink cells in the gravure printing roller, glue is distributed uniformly on the film sticky note without accumulation during the follow-up glue coating process, the glue cannot move to a bottom page, and the product is bonded firmly and easy to peel; users can write words smoothly on the film sticky note with pencils, ballpoint pens, gel pens and the like, ink can dry quickly after writing, ink marks are clear without ink removing, and various personalized colors can be selected.
Description
technical field [0001] The invention relates to a pretreatment method for film post-it notes. Background technique [0002] Film post-it notes belong to a kind of fluorescent film post-it notes coated with a special adhesive on the back. Its function is consistent with the current post-it stickers. The existing post-it In order to produce a film post-it note with the same function as the existing post-it sticker, it is necessary to carry out a special printing process on the front and back of the fluorescent film.
