Embodiment 1

[0042] Such as figure 1 Shown, the production method of pharmaceutical packaging bag, comprises the following steps:

[0043] 1) Preparation of film: Mix the raw materials for film preparation in proportion and then make film by blowing film, pressing film and trimming;

[0044] 2) Dry compounding: film A is coated with an adhesive under the action of a pressure roller, dried and cured, and then forms a composite film with film B under the action of a pressure roller; the adhesive consists of the following weight percentages: Component composition: 40% solid content, the balance is deionized water, the adhesive is isocyanate adhesive; the drying temperature is 160°C; the curing temperature is 60°C;

[0045] 3) Carry out corona treatment on the composite film;

[0046] 4) Printing of the composite film: the composite film is printed with printing ink on the composite film through a printing machine, the printing machine includes a pressure roller transmission system providing...

Abstract

The invention discloses a production method of a medicine packing bag. The production method comprises the steps of: 1) preparation of a film; 2) dry combination; 3) corona treatment of a composite film; 4) printing of the composite film; 5) irradiation of printing ink by using ultraviolet rays emitted by a first set of ultraviolet lamps of a printing machine; 6) irradiation of the printing ink by using ultraviolet rays emitted by a second set of ultraviolet lamps of the printing machine so as to cure a printing layer on the composite film; 7) drying of the printing layer by using an infrared dryer arranged on the printing machine; 8) UV glazing of the dried printing layer by using a UV glazing machine arranged on the printing machine; and 9) slitting and bagging of the printed composite film. The production method solves the problems of low firmness of the composite film and need of manual ink injection caused by a traditional composite film preparation process.

Description

technical field [0001] The invention relates to the technical field of medicine packaging, in particular to a production method of medicine packaging bags. Background technique [0002] In the pharmaceutical industry, it involves packaging the prepared pharmaceuticals. The packaging mainly includes bags and aluminum foil boards. No matter what kind of packaging is used, it involves the preparation of composite films, printing processes and bag making. [0003] 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. [0004] The printing process is to print some product information on the composite film used for packaging to facilitate the identification and use of pharmaceuticals. The equipment used in the printing process mainly includes a printing machine, a winding device, and the ink that cooperates with the...
