TECHNICAL FIELD OF THE INVENTION The present invention relates to a novel print laminating film. [Prior art and its problems] Traditionally, covers of publications such as magazines and books,
Or, to protect, preserve, or maintain the beauty of printed materials such as posters and cards, paper containers such as various food containers, and even handbags, the surface may be water-resistant, oil-resistant, or weather-resistant. A plastic film is used that has a wide range of properties, and the lamination of this film onto such printed matter or paper products (hereinafter simply referred to as printing paper, but also including plain paper) is generally called print lamination or print lamination. I'm calling. In the conventional print lamination method, a two-component adhesive made by dissolving an adhesive resin in an organic solvent is applied to a polypropylene film, and after drying to scatter the organic solvent, the adhesive-coated surface is coated. This is done by thermo-compression bonding together with the printing paper. However, when using adhesives in which organic solvents have been dissolved in this way, it requires a lot of processing during work, and there is a risk of fire as well as the problem of air pollution due to the scattering of the organic solvent gas or the problem of the gas. Occupational health problems were caused by inhalation of the substances into the body.
There were also other problems, such as the resulting equipment had low adhesive strength, poor solvent resistance, and odor. Therefore, in recent years, methods of print lamination without using such organic solvents have been proposed. For example, films have been developed in which the polypropylene film is laminated with a heat-sensitive adhesive resin made of polyethylene or a copolymer containing at least 80% polyethylene and external propylene, butene-1, etc., as well as films that are improved from this film. . Using these means that prints can be laminated without using organic solvents or adhesives, which solves the problems mentioned above, such as processing time, fire, air pollution, and occupational health. was completed. However, these films had problems in adhesion to printing paper, poor gloss after adhesion, and crushing, depending on the print lamination conditions. Also, special processing equipment or conditions had to be used. Note that "crumple" here refers to the surface condition of the film after adhesion. [Objective and Structure of the Invention] Thus, it is an object of the present invention to provide a film for print lamination that solves problems such as disaster prevention during print lamination, as well as problems such as adhesion to printing paper and subsequent gloss. The purpose is to Accordingly, the present invention provides a film for print lamination, which is made by fusing and coating a polypropylene film with a temperature-sensitive adhesive resin made of an acrylic acid-modified ethylene-vinyl acetate resin. [Detailed Description of the Invention] In the present invention, a polypropylene film is used as the base film. This may be biaxial stretching, uniaxial stretching, or non-axial stretching, and it is desirable that one or both sides of the film be subjected to corona treatment. This film may be plain or may be printed on one side. This film is coated with a temperature-sensitive adhesive resin made of acrylic acid-modified ethylene-vinyl acetate resin.
The temperature during painting should be 80-120°C, and the thickness should be in the range of 10-20 microns. When one side of the film is printed, the printed side may be coated, or the non-printed side may be coated. As the acrylic acid-modified ethylene-vinyl acetate resin used here, for example, Evaflex #40 manufactured by Mitsui Polychemical Co., Ltd. can be mentioned. It may be used as is or some additives may be added. An example of a method for print lamination using the film obtained in this way will be explained with reference to the drawings. 1 is the roll film for print lamination obtained as described above, and usually 15
It is micron thick, 780mm wide, and rolled for 3000m. The film 2 is fed by a feed roll 3 and passed through a preheating zone 4 maintained at about 50 to 60° C. at a speed of, for example, 30 m/min. Then, it is sent between a metal heat roll 5 and a heat-resistant rubber pressure roll 6, which rotate in opposite directions while contacting each other. Here is the printing paper 7 to be processed.
are sequentially fed from a paper feeder 8, and the film 2 and printing paper 7 are bonded and laminated between both rolls. The print lamination conditions at that time are usually at a temperature of 80 to 100.
℃, pressure 200~250Kg/ cm2 , speed 20~30m/min, especially temperature 90℃, pressure 220Kg/ cm2 , speed.
30 m/min is preferred. Here, the print-laminated product 9 is further sent by a feed roll 3 and taken out. In the past, laminating work required paint machines, dryers, etc., as well as measures against hazardous materials and gas poisoning, but with the present invention, such equipment and measures are not necessary, reducing processing man-hours and reducing costs. can be reduced. [Example] A film according to the present invention and other films were prepared and comparatively tested. The base films used were all biaxially stretched and corona-treated polypropylene films with a thickness of 15 microns, and various temperature-sensitive adhesive resins having the following formulations were fusion-coated onto these films to a thickness of 15 microns. Blend 1: 80 ethylene-vinyl acetate 20 copolymer resin Blend 2: 60 ethylene-40 vinyl acetate copolymer resin Blend 3: Acrylic acid-modified ethylene-vinyl acetate resin Among these, the one obtained by No. 3 is the present one. This is a film according to the invention. These films were laminated with printing paper under the following two lamination conditions. The printing paper used at this time was art paper with a basis weight of 120 g/m 2 . Condition 1: 90℃ - 220Kg/cm 2 -30m/min Condition 2: 100℃ - 220Kg/cm 2 -30m/min The adhesive strength of the printed laminated product when laminated to a white surface and the printed surface It was measured when it was pasted on. Gloss and collapse were also measured.
The results are shown in the table below. In terms of gloss and crushing,
◎ indicates very good, ◯ indicates good, and △ indicates somewhat good.

Thus, when using a printed laminating film made by fusion coating a polypropylene film with a temperature-sensitive adhesive resin made of acrylic acid-modified ethylene-vinyl acetate resin as in the present invention, it is possible to use a printed laminating film under various laminating conditions. In comparison, a product with superior adhesive strength, gloss, and crushability can be obtained.
Of course, there are no problems in terms of disaster prevention or environmental hygiene, and it is truly effective.
