Abstract
The invention discloses a sealing film for food and medicines, which comprises a hot sealing layer and a peeling layer. The hot sealing layer is a polyethylene material layer added with modified materials. The modified materials are homopolymerized or copolymerized polypropylene materials or copolymerized polybutylene materials or mixed materials of homopolymerized or copolymerized polypropylene and copolymerized polybutylene. Certain hot sealing strength of the sealing film for food and medicines and a container is guaranteed, accordingly, hot sealing effect is excellent, gas leakage is avoided, and simultaneously, the sealing film has excellent easy-peeling property, is lower in integral preparation cost and has great practicality.
Description
Technical field
The present invention relates to the packaging cover field, particularly a kind of to be applied to medicine or packaging for foodstuff and top layer be the capping film of polyethylene kind container.
Background technology
At present; Have on a kind of opening that is encapsulated in plastic container and the plastic sheeting of being stripped from easily; After outer aluminum plastic film is peeled off; What the internal layer hot sealing layer was still complete is welded on the plastic container, and the gas that the material in the container gives out can see through in the heat-sealing film entering ambient air by actv., reaches therapeutic purposes or enhancement of environment purpose.
In the existing product, how to make hot sealing layer with ethene-vinyl acetate or simple poly-vinyl etc. on the market, its shortcoming is that cost is high, and it is poor to be prone to taking off property.
Summary of the invention
For overcoming deficiency of the prior art, the object of the present invention is to provide a kind of hot sealing layer compounding method of excellent combination property, can guarantee needed certain sealing-strength, and be prone to take off that cost is low.
In order to solve the problems of the technologies described above, realize above-mentioned purpose, the present invention has adopted following technical scheme:
A kind of food, medicine are used the capping film, comprise a hot sealing layer and a peel ply, and said hot sealing layer is the material modified polythene material layer of an adding.
Preferably, said material modified be homopolymerization or COPP material.
Preferably, the said material modified copolymerization polybutene material that is.
Preferably, said material modified composite material for homopolymerization or COPP and copolymerization polybutene.
Further, the proportioning of said homopolymerization or COPP material and said polythene material is 15～20: 80～85.
The proportioning of said copolymerization polybutene material and said polythene material is 10～20: 80～90.
Proportioning between said homopolymerization or COPP material, said copolymerization polybutene material and the said polythene material is 5～10: 5～10: 80～90.
Food compared with prior art of the present invention, medicine have the following advantages with the capping film:
The product practical effect is seen, has both guaranteed capping film and the certain heat seal strength of container, makes involution respond well, and is air tight, have good the taking off property that is prone to again simultaneously, and whole formulation cost is lower, has very big practicality.
Above-mentioned explanation only is the general introduction of technical scheme of the present invention, understands technological means of the present invention in order can more to know, and can implement according to the content of specification sheets, below with preferred embodiment of the present invention and conjunction with figs. specify as after.The specific embodiment of the present invention is provided by following examples and accompanying drawing thereof in detail.
