According to an optimized scheme, the first bonding layer and the second bonding layer are both solvent-free adhesives.
According to an optimized scheme, the first bonding layer is a two-component polyurethane adhesive, and the second bonding layer is a one-component polyurethane adhesive.
The optimized scheme is a processing technology of a visual environment-friendly medicinal composite membrane based on a temperature-sensitive technology, and comprises the following steps:
1) pattern printing is carried out on the surface of the first polyester film layer;
2) compounding the first polyester film layer treated in the step 1) with the second polyester film layer to obtain a semi-finished product of the composite film;
3) taking a semi-finished product of the composite film, and carrying out primary curing;
4) compounding the semi-finished product of the composite film treated in the step 3) with a polyethylene film layer to obtain a finished product of the composite film;
5) taking a finished product of the composite film, and carrying out secondary curing;
6) and 5) cutting, inspecting, packaging and warehousing the finished composite film product treated in the step 5).
The optimized scheme comprises the following steps:
1) taking a first polyester film layer, and printing patterns on the surface of the first polyester film layer by adopting an imprinting technology; in the step 1), pattern printing is carried out on the surface of the first polyester film layer, and an impression technology is adopted during printing, so that the printed first polyester film layer has easy tearing property; the printing ink used when the first polyester film layer is printed with the color patterns is benzene-free printing ink, and replaces the traditional solvent type printing ink, so that the prepared medicine packaging composite film is more environment-friendly and safer;
2) coating a double-component polyurethane adhesive on the surface of the first polyester film layer treated in the step 1) to form a first adhesive layer, and compounding the first polyester film layer, the first adhesive layer and the second polyester film layer to obtain a semi-finished product of the composite film; compounding the first polyester film, the first adhesive layer and the second polyester film in the step 2), wherein the step is solvent-free compounding, a high-temperature oven is not needed in the compounding process, and an organic solvent is not needed in the production process, so that the method is safe and environment-friendly;
3) placing the semi-finished product of the composite film in a curing chamber, controlling the environmental humidity to be 55-65%, curing for 18-24h at 25-30 ℃, then heating to 35-40 ℃, and continuing curing for 12-18 h; curing the prepared composite film semi-finished product twice in the step 3) to ensure that the bonding layer is more sufficient after being dried and cured;

The coating amount of the two-component polyurethane adhesive is limited, the condition of uneven rolling caused by too large gluing amount can also cause the ink to be transferred from a base material, if the gluing amount is too small, the peeling strength is reduced, bubbles are remained due to insufficient gluing amount and ink infiltration, and the coating amount is set to be 3-4g/m2。
Meanwhile, when the two-component polyurethane adhesive is coated, if the gluing speed is too high, the adhesive on the surface of the first polyester film layer is not uniformly coated, and the gluing speed is too low, which reduces the production efficiency, so the gluing speed is set to 300-400 m/min.
