Abstract

(57) [Summary] [PROBLEMS] To apply a structure of a pressure-sensitive adhesive sheet for printing composed of a pressure-sensitive adhesive, a release agent, and a support used for a label seal or the like to a laminating film and to newly pass through a laminator machine. By developing a two-layer adhesive laminating film for backside processing of printed materials that can be used, it is possible to prevent deformation of posters attached to wall surfaces due to changes in humidity and to easily attach them with an adhesive, and easily peel off when unnecessary It becomes possible. In order to achieve the above object, a thickness of 0.01
A 5-mm to 0.03 mm polypropylene film (A, D) is formed into a two-layer structure for bonding and peeling, and a re-peelable pressure-sensitive adhesive (B) is applied to the opposing surface of the bonding film (A). A silicone release agent (C) is applied to the opposite surface of the release film (D) to adhere the two layers. By forming a two-layer film made of this combination into a roll, it can be used in a laminator machine. Further, the two-layer film composed of this combination can be used for laminating by conventional thermocompression bonding.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a laminated film for processing a printed material back surface, and more particularly to a two-layer film composed of an adhesive film and a release film, which is laminated on a printed material back surface using a laminator machine.

[0002]

[Prior art]

 Conventionally, there is no film that is laminated on the back of a large printed matter such as a poster by using a laminator machine. Generally, when sticking Boster to a wall, double-sided adhesive tape is used on the back surface, or transparent adhesive tape is used from the front surface.

[0003]

[Problems to be solved by the invention]

 Applying the structure of the pressure-sensitive adhesive sheet for printing, consisting of an adhesive, release agent, and support, used for label seals, etc. to a laminating film, and a new two-layer process for the backside of printed materials that can be passed through a laminator machine By developing a film for adhesive lamination, it is possible to prevent deformation of posters attached to wall surfaces due to changes in humidity, and to make it possible to easily attach it with a removable adhesive, and to easily peel it off when unnecessary. Become.

[0004]

[Means for Solving the Problems]

 In order to achieve the above object, a polypropylene film having a thickness of 0.015 mm to 0.03 mm is formed into a two-layer structure for bonding and peeling, and a re-peelable pressure-sensitive adhesive is provided on the opposing surface of the bonding film. After applying, a silicone release agent is applied to the opposite surface of the release film to adhere the two layers. A two-layer film made of this combination can be used in a laminator machine by forming it into a roll. Further, the two-layer film composed of this combination can be used for laminating by conventional thermocompression bonding.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION In FIG. 1, the structure and combination of a two-layer adhesive laminating film for processing the back side of printed matter will be described. Substrates A and D use a polypropylene film having a thickness of 0.015 mm to 0.03 mm, B is an adhesive layer, and C is a silicone release layer. A and D are adhered with only slight pressure at room temperature for a short period of time, and the base polypropylene is a hard and smooth surface with excellent releasability, making it an optimal combination for thermocompression lamination.

An embodiment will be described from the lamination process. The roll-shaped two-layer adhesive laminating film for processing the back side of printed matter is completed by the step of applying an adhesive for bonding to the back side of the printed matter, the step of drying the adhesive, and the step of thermocompression bonding with the printed matter. .

[0007]

[Effect of the invention]

 The work of pasting the poster on the wall becomes easy and quick. In addition, deformation of the poster or the like at the time of delivery or after pasting can be prevented, and since the removable adhesive is used, the poster can be easily peeled off.
