Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Examples: referring to fig. 1, the utility model provides an iodine-resistant aluminum foil blister packaging structure, which comprises an aluminum foil layer 1 and a polyvinyl chloride sheet 7, wherein gravure aluminum foil ink is printed on the upper surface of the aluminum foil layer 1, and varnish 2 is fixedly coated on the upper surface of the aluminum foil layer 1, wherein the varnish 2 comprises the following components in percentage concentration: 60% of ethyl acetate, 5% of cellulose resin, 10% of butyl ether amino resin and 25% of polyacrylic resin, and the varnish 2 can protect gravure aluminum foil ink after curing and increase the glossiness, wear resistance and water resistance of the aluminum foil layer 1.
The lower surface of the aluminum foil layer 1 is fixedly coated with a vinyl resin heat-seal coating 3, the lower surface of the vinyl resin heat-seal coating 3 is fixedly coated with a PVA coating 4, the lower surface of the PVA coating 4 is fixedly coated with VC glue 5, the lower surface of the VC glue 5 is fixedly coated with a polyurethane heat-seal coating 6, and the lower surface of the polyurethane heat-seal coating 6 is fixedly connected with a polyvinyl chloride sheet 7. Wherein the thickness of the vinyl heat-seal coating 3, the PVA coating 4, the VC glue and the polyurethane heat-seal coating 6 are the same.
In the embodiment, the PVA coating 4 is polyvinyl alcohol resin, and has the advantages of no toxicity, no smell, no pollution, good film formability, good flexibility and high toughness. The PVA coating 4 is a barrier functional layer, and when iodine contacts with the PVA coating 4, since the polymer chain of the polyvinyl alcohol resin is composed of a plurality of vinyl alcohol units, the units are connected together through covalent bonds to form a relatively uniform and continuous polymer chain structure, and the closely arranged structure enables the PVA coating 4 to have higher density and compactness, and can well prevent iodine molecules from entering the PVA coating through molecular gaps and pores of the PVA coating. Thus, PVA coating 4 is effective in preventing diffusion and permeation of iodine, maintaining the integrity and stability of the package. Since aluminum is a metal having a low surface energy, the surface thereof tends to be difficult to adhere to the PVA coating layer 4. The present embodiment connects the aluminum foil layer 1 and the PVA coating layer 4 by the vinyl heat sealing coating layer 3 as a heat sealing adhesive.
Above the above-described examples, the vinyl heat-seal coating 3 in this example was prepared from ethyl acetate, vinyl resin and polyester polyol resin, and had excellent adhesive strength with the aluminum foil layer 1. Wherein ethyl acetate is mainly used as a diluent; the vinyl resin is used for increasing the adhesiveness and the wear resistance of the coating, and the hydroxyl of the polyvinyl alcohol resin and the carbonyl, alkenyl and other chemical functional groups of the vinyl resin heat-sealing coating 3 interact to form hydrogen bonds and covalent bonds, so that reliable bonding is realized; the polyester polyol resin is used to increase the flexibility and chemical resistance of the vinyl heat seal coating 3.
Above the above embodiments, the VC glue 5 in this embodiment is a chlorinated polyethylene resin-based glue with excellent adhesion properties and chemical stability. The chlorinated polyethylene resin can form physical and chemical combination with the polyvinyl alcohol resin, so that the PVA coating 4 and the VC glue 5 can be reliably bonded.
According to the utility model, an iodine-blocking structure is constructed between the aluminum foil layer 1 and the polyvinyl chloride sheet 7 in a four-layer step coating mode, the vinyl resin heat-seal coating 3, the PVA coating 4, the VC glue 5 and the polyurethane heat-seal coating 6 are uniformly coated, the adhesion effect is good, the iodine-blocking effect is good, the vinyl resin heat-seal coating 3 and the PVA coating 4 have good flexibility, and the packaging impact resistance effect is good.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
