Problems solved by technology

After the composite film is made, it needs to be dried and matured. Due to the poor control of the drying process in the existing composite film processing technology, it is easy to cause low fastness and poor quality of the composite film, and the qualified rate of the produced packaging bags is low.

Embodiment 1

[0026] A pharmaceutical composite film processing technology, comprising the following steps: (1) preparing film A and film B;

[0027] (2) Use the unwinding roller to unwind the film A;

[0028] (3) Printing: use a printing machine to print the film A;

[0029](4) Glue coating: under the action of anilox roller, coat film B with adhesive, and then dry; drying adopts three-stage heating, first stage: 54°C, time 15s; second stage: 68°C, time 14s; the third stage: 75°C, time 10s; when drying, the air is sent in at a speed of 35m / s per second, and the air is sent out at a speed greater than 2m / s.

[0030] (5) Humidity callback: After the film B is dried, fine-tune the humidity to control the moisture content of the film B at 4.6-8%;

[0031] (6) Composite: Composite film A and film B are composited into a composite film 40 by using a composite machine, and the composite film 40 is wound on the take-up roller; the composite speed of the composite machine is controlled at 110-130...

Embodiment 2

[0035] The difference between Example 2 and Example 1 is: (4) Glue application: under the action of anilox roller, film B is coated with adhesive, and then dried; drying is carried out in three stages of heating, the first stage: 58°C, The time is 15s; the second stage is 70°C, the time is 10s; the third stage: 78°C, the time is 10s; when drying, the air is sent in at a speed of 38m / s per second, and the air is sent out at a speed greater than the air supply speed of 2m / s.

Embodiment 3

[0037] The difference between Example 3 and Example 1 is: (4) Glue application: Under the action of anilox roller, film B is coated with adhesive, and then dried; the drying adopts three-stage heating, the first stage: 64°C, The time is 12s; the second stage: 72°C, the time is 12s; the third stage: 82°C, the time is 10s; when drying, the air is sent in at a speed of 43m / s per second, and the air is sent out at a speed greater than 2m / s .

Abstract

The invention belongs to the technical field of medicine packaging, and particularly discloses a medicinal composite membrane machining process. The medicinal composite membrane machining process comprises following steps: firstly, a thin membrane A and a thin membrane B are prepared; secondly, an unwinding roller is used for unwinding the thin membrane A; thirdly, printing is carried out, whereina printing machine is used for printing the thin membrane A; fourthly, gluing is carried out, wherein under the action of an anilox roller, the thin membrane B is coated with a bonding agent, dryingis carried out, three-stage heating is adopted in drying, in the first stage, the temperature ranges from 52 DEG C to 64 DEG C, the time ranges from 12 s to 18 s, in the second stage, the temperatureranges from 65 DEG C to 72 DEG C, time ranges from 10 s to 16 s, and in the third stage, the temperature ranges from 73 DEG C to 82 DEG C, and the time ranges from 6 s to 12 s; fifthly, humidity re-adjustment is carried out, wherein after the thin membrane B is dried, the humidity is subject to micro adjustment, and the water containing rate of the thin membrane B is controlled to range from 4.6 %to 8 %; sixthly, compositing is carried out; seventhly, curing is carried out. Through the technical scheme, the composite membrane is prepared, through control over the drying procedure, the obtained composite membrane is high in transparency and good in quality.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical packaging, and in particular relates to a processing technique of a medicinal composite film. Background technique [0002] In the pharmaceutical industry, it involves packaging the prepared medicines. The packaging mainly includes bags and aluminum foil plates. No matter what kind of packaging is used, it involves the preparation of composite films. The preparation of the composite film is to compound and solidify the single-layer film through the printing process and then through the dry composite process or the extrusion composite process to form a composite film. After the composite film is made, it needs to be dried and matured. Due to the poor control of the drying process in the existing composite film processing technology, it is easy to cause the composite film to have low fastness and poor quality, and the qualified rate of the produced packaging bags is low.
