Double-side hot-melt adhesive film and process for making same

Abstract

The invention discloses a hot-melt adhesive film, in particular to a double-sided hot-melt adhesive film suitable for painting and calligraphy mounting. It is composed of the following structure: the two sides of the paper layer are coated with a hot melt adhesive layer. The preparation process of double-sided hot-melt adhesive film, which includes the following process steps: heating the hot-melt adhesive used to 120-160 ° C, then coating the heated hot-melt adhesive on both sides of the paper, and then applying the hot-melt adhesive coated The melted paper is pressed and formed to obtain the finished product. The invention provides the mounting industry with a double-sided hot-melt adhesive film that simplifies the mounting operation. Its thickness is uniform, and the calligraphy and painting works after mounting are smooth. When the double-sided hot-melt adhesive film of the present invention is used for mounting, it is not easy to wrinkle and deform. , its cost is low, reduces the mounting cost, is not easy to penetrate, the mounting time is short, and the preparation process of the product of the present invention is simple. The invention is convenient for implementation and has broad market prospect.

Description

Technical field [0001] The invention relates to a hot-melt adhesive film, in particular to a double-sided hot-melt adhesive film suitable for painting and calligraphy mounting. Background technique [0002] Painting and calligraphy works must be framed to facilitate hanging, displaying, appreciating and collecting. The level of mounting technology and the selection of mounting materials directly affect the artistic effect and collection value of calligraphy and painting works, especially whether the adhesive material is suitable or not has a greater impact on the effect and value of the final mounted work. Therefore adhesive material is an indispensable product in mounting technology. Paintings and calligraphy works mounted with traditional adhesive materials tend to get moldy; however, the current ordinary adhesive film for mounting is expensive, difficult to mount, uneven in thickness distribution, wastes human resources for a long time for mounting, and is easy to instal...
