Embodiment 1

[0023] A 1100mm wide gravure rotary high-speed printing machine is used to add benzene and ketone-free inks for printing; the non-printing surface of the aluminum foil is coated with a screen roll as a coating roll, coated with a two-component polyurethane resin glue, and then passed through 50 ° C, Dry the solvent in a three-stage oven at 60°C and 70°C, enter the composite roller and polyethylene film, and then wind up to form a composite semi-finished product; put the above composite semi-finished product in a curing room at 50°C for 36 hours; put the composited The packaging film is cut into roll film with a 1000mm wide slitting machine; the cut roll film is made into a center seal bag or a three side seal bag or other Shaped bag.

[0024] The composite film for pharmaceutical packaging prepared in this example has clear layers, beautiful appearance, pressure resistance, compact composite, no blistering, no rupture, high peel strength, good heat sealing performance, and goo...

Embodiment 2

[0026] A 1100mm wide gravure rotary high-speed printing machine is used to add benzene and ketone-free inks for printing; the non-printing surface of the aluminum foil is coated with a screen roll as a coating roll, and coated with a two-component polyurethane resin glue. Dry the solvent in a three-stage oven at 65°C and 75°C, enter the composite roll and heat the polyethylene film, and then wind up to form a composite semi-finished product; put the above composite semi-finished product in a curing room at 55°C for 48 hours; put the composited The packaging film is cut into roll film with a 1000mm wide slitting machine; the cut roll film is made into a center seal bag or a three side seal bag or other Shaped bag.

Abstract

The invention relates to a composite film for medicine packaging, and a making method thereof. The composite film for medicine packaging comprises an aluminum foil layer and a modified polyethylene layer from top to bottom, an aqueous binder is coated between the aluminum foil layer and the polyethylene layer, and the aqueous binder is a polyurethane binder. The making method of the composite film for medicine packaging sequentially comprises the operations of printing, compounding, curing, slitting, and bag making. The composite film for medicine packaging has the advantages of distinct gradation, beauty, pressure resistance, close compounding, no bubbles, no fracture, large peeling strength, good heat sealing performance, easy tearing and easy uncovering.

Description

technical field [0001] The invention belongs to the technical field of medicine packaging, and in particular relates to a composite film for medicine packaging and a preparation method thereof. Background technique [0002] The composite flexible packaging industry began to develop in the middle of the 20th century, and it has increasingly shown its importance in pharmaceutical packaging. This type of composite film consists of substrates, laminating adhesives, barrier materials, heat-sealing materials, printing and protection layer of paint etc. [0003] There are many kinds of medicine package products, and different contents have different requirements for packaging materials. Many medicines require light-shielding, water-blocking, oxygen-blocking, and good formability, especially some medicines require easy tearing, and many directional materials The composite membranes produced, while exhibiting excellent performance in other respects, were deficient in this respect. ...
