Problems solved by technology

However, in practical applications, the composite packaging film is easily deformed, broken or even delaminated under the action of heat or external force, resulting in a change in the barrier properties of the drug packaging film during heat sealing, which is not conducive to the long-term storage of drugs

Abstract

The invention discloses a high-barrier medicine packaging film. The high-barrier medicine packaging film comprises an aluminum layer and a base layer, the aluminum layer and the base layer are bondedby an adhesive, and the adhesive is prepared from polyvinylidene chloride, epoxy resin, nanometer titanium dioxide, nano-alumina, carboxymethyl cellulose, graphene, a plasticizer, a coupling agent, acuring agent and a stabilizer. The barrier film has high barrier to water and air, and can significantly prolong the shelf life of medicines. The invention also provides a preparation method of the high-barrier medicine packaging film.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging, in particular to a high barrier film for pharmaceutical packaging and a preparation method thereof. Background technique [0002] Pharmaceutical packaging refers to the use of appropriate materials or containers, the use of packaging technology to divide (fill), seal, pack, and label semi-finished or finished pharmaceutical preparations, and provide quality assurance, identification of trademarks and instructions for pharmaceuticals. General term for processing. [0003] For the field of pharmaceutical packaging, adhesives are essential raw materials in packaging materials. The adhesives used for pharmaceutical packaging materials should have good safety and hygiene performance. They should be non-toxic and odorless. If they come into direct contact with the pharmaceuticals, they must be non-corrosive and will not cause damage to the packaged pharmaceuticals. In addition, in order to ext...
