Description

A kind of medical film

Technical field

The utility model relates to a kind of packaging material, and more particularly, it relates to a kind of medical film.

Background technology

At packaging field, thin film is widely used.Along with the development of science and technology, single film cannot meet production and living needs, therefore occurs increasing laminated film on the market, and laminated film is also quite general in the application of Key works Drug packing field, and this characteristic with medicine itself is also relevant.But existing laminated film has to be strengthened in sealing, stretch-proof, the performance such as wear-resisting.The utility model is to provide the medical film that a kind of high leakproofness, tensile resistance are strong, wearability is good.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide the medical film that a kind of high leakproofness, tensile resistance are strong, wearability is good.

For achieving the above object, the utility model provides following technical scheme:

A kind of medical film, comprises PVC basic unit, described PVC basic unit is provided with successively aluminium foil composite bed, linear low density polyethylene layer and biaxial tension propylene layer, is provided with adhesive between adjacent two layers material.

The utility model is set to further: described adhesive is epoxy adhesive.

The utility model is set to further: the thickness of described aluminium foil composite bed, linear low density polyethylene layer and biaxial tension propylene layer is 0.01mm.

The utility model is set to further: described biaxial tension propylene layer is anti oxidation layer.

Compared with prior art, the utility model has the advantages that: this medical film is formed by multilayer material adhesion, this kind of film be tool high leakproofness, stretch-proof, the premium properties such as wear-resisting simultaneously, is adapted at medical packaging field and promotes.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

Description of reference numerals: 1, PVC basic unit; 2, aluminium foil composite bed; 3, linear low density polyethylene layer; 4, biaxial tension propylene layer.

Detailed description of the invention

As Fig. 1, a kind of medical film, comprises PVC basic unit 1, and PVC basic unit 1 is provided with aluminium foil composite bed 2, linear low density polyethylene layer 3 and biaxial tension propylene layer 4 successively, and adjacent two layers material sticks with glue agent adhesion.In medical packaging field, usually require that medical thin film is for performances such as good air-tightness, stretch-proof and wearabilities, to ensure that medicine is not perishable.The utility model is covered with one deck aluminium foil composite bed 2 in traditional PVC basic unit 1, foil laminated film mechanical strength is good, light-proofness is good, poor stability can be applied to, the medicine of photochemical degradation easily occurs, in addition, foil laminated film good barrier property, moistureproof and waterproof, air-tightness are strong, effectively can prevent air and moisture and drug contact, thus prevent medicine from going bad.For strengthening the stretch-resistance of medical film, the utility model is covered with linear low density polyethylene layer 3 on aluminium foil composite bed 2, and LLDPE is LLDPE.Linear low density polyethylene (LLDPE) has the performance of good stretch-proof, penetration, shock resistance and tear-proof; linear low-density polyethylene film covers on aluminium foil composite bed 2; can aluminium foil composite bed 2 be prevented to be worn and to pull cracking by available protecting aluminium foil composite bed 2, thus medicine can be protected better.In addition, the utility model is also covered with biaxial tension propylene layer 4 in linear low density polyethylene layer 3, the physical stability of biaxial tension Polypropylene film, mechanical strength, air-tightness are better, transparency and glossiness higher, tough and hard wear resistant, be current most widely used printing film, be generally used as the outer membrane of laminated film.Biaxial tension Polypropylene film overlays on linear low-density polyethylene film surface and linear low-density polyethylene film can be protected to be worn.In addition, have benefited from biaxial tension Polypropylene film excellent printing performance, various pattern and word can be printed with drug labeling information on double stretching Polypropylene film.For preventing the word above biaxial tension Polypropylene film, pattern is oxidized and fade, and is mixed with antioxidant (as Tea Polyphenols), makes biaxially oriented film have non-oxidizability in biaxially oriented film, and the word, the pattern that prevent from being printed on its surface fade.

It should be noted that, bonding by epoxy adhesive between layers of material of the present utility model.

As preferably, aluminium foil composite bed 2, linear low density polyethylene layer 3 and biaxial tension propylene layer 4 thickness are 0.01mm.

The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
