Next, in the same manner as described above, the adhesive for laminating in each example and each comparative example was applied to the other surface of the nylon film of the two-layer composite film, and the solvent was stripped. Pasted together. Next, in the same manner as described above, the adhesive for laminating in each example and each comparative example was applied to the other surface of the aluminum foil of the three-layer composite film, and the solvent was stripped. Bonded with stretched polypropylene film. Thereafter, the four-layer composite film was cured at 50 ° C. for 3 days to cure the laminating adhesive.
- a test piece having a length of 300 mm and a width of 15 mm was produced, and using a Instron type tensile tester, the test piece was heated to 90 ° C, The adhesive strength (adhesive strength under wet heat) was measured at a peeling speed of 300 mmZ. The measured value was shown as the average value of the five test pieces as the adhesive strength (g / 15 mm) between the aluminum foil and the unstretched polypropylene film (inner layer) (between ALZCPP).
- This bag was sterilized with hot water at 135 ° C for 20 minutes under a pressure of 3.5 kgZcm 2 , and immediately after the hot water sterilization treatment and after storage for 14 days at 60 ° C with aluminum foil and nylon Finolem (outer layer) ) (Between NYZAL) and the adhesive strength (gZl5mm). The measured value was shown as an average value of five test pieces.
- the adhesive for lamination of the present invention is useful for laminating films in the production of packaging materials in various industrial fields such as foods, beverages, pharmaceuticals and quasi drugs.
