Abstract
The utility model discloses a kind of composite packing film, belong to packaging material field.A kind of composite packing film of the present utility model, comprises top layer, intermediate layer and internal layer from outside to inside successively, and described top layer is pet layer or ply of paper; Described intermediate layer is aluminium foil, and described internal layer is the functional film with moisture absorbing or oxygen uptake function or moisture absorption oxygen uptake function.The utility model structure is simple, can not only the infiltration of passive obstruct aqueous vapor and oxygen, and can initiatively adsorb aqueous vapor and oxygen, and result of use is good.
Description
Technical field
The utility model relates to packaging material, more particularly, relates to a kind of composite packing film.
Background technology
Composite package film refers to be formed through printing compound etc. technique by plural layers.Be divided into aluminium plastic composite packaging film and mould composite package film according to material, be divided into two layers, three layers, four layers, five layers etc. by material structure, be widely used in foreign export, papermaking, five metals, plastics chemical industry, building materials, food pharmaceuticals industry.Now with medicinal industry with being packaged as example, medicine is kind of a specialty goods, and Key works Drug packing is the same with other commodity packagings, and its quality directly can have influence on the sale of medicine.At present, on market, most composite membrane for packaging medicine is composited by adhesive at various plastics, soft aluminium foil or other aluminized plastic, bag can be processed into further, be mainly used in the packaging of pulvis, granule, the prepared slices of Chinese crude drugs, tablet, transdermal patch and medicine equipment etc.Composite membrane for packaging medicine is the main packaged form of Chinese medicine, is also the pulvis of infant and the main packaged form of granule medicine, in the medical packaging of China, occupies larger proportion.But existing composite membrane for packaging medicine mainly adopts trilaminate material to be composited, respectively be polyester layer, aluminium foil layer and polyethylene layer, each layer is connected by adhesive, this composite membrane has certain rub resistance, the performances such as puncture-resistant, the infiltration of inside and outside gas or liquid can be stoped in ground, but such composite package film itself does not have the function of moisture absorption or oxygen uptake, can only the infiltration of gas or liquid inside and outside passive prevention, initiatively can not absorb the aqueous vapor in packaging bag that composite membrane does and oxygen, and then impact is arranged on storage and the period of guarantee of the medicine in packaging bag.
Summary of the invention
1. the utility model technical problem that will solve
The purpose of this utility model is to overcome the deficiency that existing composite package film itself does not have moisture absorption or oxygen uptake function, provide a kind of composite packing film, adopt the technical solution of the utility model, internal layer is the functional film with moisture absorbing or oxygen uptake function or moisture absorption oxygen uptake function, make that itself there is moisture absorption or oxygen uptake function, can not only the infiltration of gas or liquid inside and outside passive prevention, and the aqueous vapor can initiatively absorbed in packaging that composite membrane does and oxygen, result of use is better.
2. technical scheme
For achieving the above object, the technical scheme that the utility model provides is:
A kind of composite packing film of the present utility model, comprises top layer, intermediate layer and internal layer from outside to inside successively, and described top layer is pet layer or ply of paper; Described intermediate layer is aluminium foil, and described internal layer is the functional film with moisture absorbing or oxygen uptake function or moisture absorption oxygen uptake function.
Further, between described top layer and intermediate layer, between intermediate layer and internal layer, all adhesive layer is set.
3. beneficial effect
The technical scheme adopting the utility model to provide, compared with existing known technology, has following beneficial effect:
(1) a kind of composite packing film of the present utility model, its intermediate layer is aluminium foil, can stop the infiltration of inside and outside gas or liquid well, can the infiltration of passive obstruct aqueous vapor and oxygen;
(2) a kind of composite packing film of the present utility model, its internal layer is the functional film with moisture absorbing or oxygen uptake function or moisture absorption oxygen uptake function, and initiatively can absorb the aqueous vapor in packaging that composite membrane does and oxygen, result of use is better.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of composite packing film of the present utility model.
Label declaration in schematic diagram: 11, top layer; 12, intermediate layer; 13, internal layer
Detailed description of the invention
For understanding content of the present utility model further, in conjunction with the accompanying drawings and embodiments the utility model is described in detail.
Embodiment
Composition graphs 1, a kind of composite packing film of the present embodiment, use as composite membrane for packaging medicine, comprise top layer 11, intermediate layer 12 and internal layer 13 from outside to inside successively, top layer 11 is pet layer or ply of paper; Intermediate layer 12 is aluminium foil, can stop the infiltration of inside and outside gas or liquid well, can the infiltration of passive obstruct aqueous vapor and oxygen; Internal layer 13 is for having the functional film of moisture absorbing or oxygen uptake function or moisture absorption oxygen uptake function, initiatively can absorb aqueous vapor in packaging that composite membrane does and oxygen to ensure storage and the period of guarantee of medicine, can solve existing composite membrane for packaging medicine may the problem of remaining aqueous vapor and oxygen when sealing, and result of use is better; Between top layer 11 and intermediate layer 12, between intermediate layer 12 and internal layer 13, all adhesive layer is set; And above-mentioned functional film 3 can by PVC/PP/PE, add moisture absorption additive or oxygen uptake additive or add moisture absorption in the lump, oxygen uptake additive obtains, and is prior art.
A kind of composite packing film of the present utility model, structure is simple, can not only the infiltration of passive obstruct aqueous vapor and oxygen, and can initiatively adsorb aqueous vapor and oxygen, and result of use is good.
Schematically above be described the utility model and embodiment thereof, this description does not have restricted, and also just one of the embodiment of the present utility model shown in accompanying drawing, actual structure is not limited thereto.So, if those of ordinary skill in the art enlightens by it, when not departing from the utility model and creating aim, design the frame mode similar to this technical scheme and embodiment without creationary, protection domain of the present utility model all should be belonged to.
Claims (2)
1. a composite packing film, comprises top layer (11), intermediate layer (12) and internal layer (13) from outside to inside successively, it is characterized in that: described top layer (11) is pet layer or ply of paper; Described intermediate layer (12) is aluminium foil, and described internal layer (13) is for having the functional film of moisture absorbing or moisture absorption oxygen uptake function.
2. a kind of composite packing film according to claim 1, is characterized in that: between described top layer (11) and intermediate layer (12), all arrange adhesive layer between intermediate layer (12) and internal layer (13).
