Problems solved by technology

Simply pursuing the barrier properties of packaging materials cannot effectively solve the penetration of external water vapor into the packaging material from the edge of the heat-sealed part to the inner space of the packaging, nor can it reduce the moisture absorbed on the surface of the drug and the moisture in the air enclosed in the packaging during packaging operations.

Abstract

The invention relates to a moisture absorption type high-barrier blister packaging rigid sheet. The moisture absorption type high-barrier blister packaging rigid sheet comprises a polytrifluorochloroethylene layer, a first polyurethane adhesive layer, a polyvinyl chloride layer, a second polyurethane adhesive and a moisture absorption film layer. By combination of high-barrier materials and moisture absorption functional materials, permeation of vapor on the front surface of packaging materials towards inner package space can be reduced while moisture permeating towards the inner package space from edges of heat seal portions of the packaging materials can be effectively and fixedly adsorbed, and moisture in air sealed in packages can be adsorbed and reduced, so that a quality protection function of medicine blister packages can be improved.

Description

technical field [0001] The invention relates to the field of pharmaceutical packaging materials, in particular to a hygroscopic high-barrier blister packaging hard sheet. Background technique [0002] The form of pharmaceutical blister packaging in my country has developed rapidly in recent years. The demand for heat-sealing equipment with simple structure and fast speed is increasing, and a variety of options have emerged, providing effective solutions for many small and difficult-to-pack products. In terms of pharmaceutical blister packaging materials, my country mainly relied on imports in the past, but up to now, the aluminum foil and blister materials for blister packaging have been fully localized and can meet the needs of domestic pharmaceutical packaging; the development of domestically produced blister substrates has gradually formed Serialization, from the most widely used PVC hard sheet, to composite materials such as PVDC coated sheet and cold-formed aluminum-plas...
