Abstract
The utility model discloses a super thick medical blister pack membrane, it is five layers of composite construction, and these five layers of composite construction are first polyethylene layer, second polyethylene layer, bond line, first polypropylene layer and second polypropylene layer to interior according to the preface outside from, the bond line is modified polyethylene layer, the thickness of packaging film is 0.20 -0.30mm. Structure more than adopting, first polyethylene layer, second polyethylene layer make the packaging film have characteristics that higher rigidity, hardness and mechanical strength are big, and first polypropylene layer and second polypropylene layer make the packaging film still have the characteristics of the high transparency and deflection, and in addition, the bond line is modified polyethylene material, can improve the compatibility of polyethylene and polypropylene, the layer and layer between to adhere the effect more firm, be difficult for the layering, the yield of packaging film is higher. Furthermore, the utility model discloses a packaging film is thicker, has improved the bulk strength and the shaping effect of packaging film, and the packaging film can not produce the fold.
Description
Technical field
The utility model relates to packaging film field, particularly relates to super thick medical blister packaging film.
Background technology
The paper that medical blister packaging film is mainly used in disposable preformed sterile system easily tears, moulds the packaging of the medicine equipment articles for use easily torn.The thickness of current medical blister packaging film is generally at 0.03-0.15mm, and the thinner thickness of packaging film, the mouldability of packaging film is poor and easily produce fold.
Summary of the invention
In order to solve deficiency of the prior art, the purpose of this utility model is the super thick medical blister packaging film providing a kind of good forming effect.
For achieving the above object, the utility model is by the following technical solutions:
Super thick medical blister packaging film, described packaging film is five layers of composite construction, these five layers of composite constructions are sequentially the first polyethylene layer, the second polyethylene layer, adhesive layer, the first polypropylene layer and the second polypropylene layer from outside to inside, described adhesive layer is modified poly ethylene layer, and the thickness of described packaging film is 0.20-0.30mm.
Described five layers of composite construction are shaping by coextrusion film blowing.
The utility model adopts above technical scheme, first polyethylene layer, the second polyethylene layer make packaging film have the large feature of higher rigidity, hardness and mechanical strength, first polypropylene layer and the second polypropylene layer make packaging film also have the feature of high transparent and deflection, in addition, adhesive layer is modified polyethylene material, and can improve polyethylene and polyacrylic compatibility, bonding effect is more firm between layers, not easily layering, the yield rate of packaging film is higher.And packaging film of the present utility model is thicker, improve bulk strength and the molding effect of packaging film, packaging film can not produce gauffer.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model is five layers of composite construction, these five layers of composite constructions are sequentially the first polyethylene layer 1, second polyethylene layer 2, adhesive layer 3, first polypropylene layer 4 and the second polypropylene layer 5 from outside to inside, described adhesive layer 3 is modified poly ethylene layer, and the thickness of described packaging film is 0.20-0.30mm.
Described five layers of composite construction are shaping by coextrusion film blowing.
In the utility model, first polyethylene layer 1, second polyethylene layer 2 makes packaging film have the large feature of higher rigidity, hardness and mechanical strength, first polypropylene layer 4 and the second polypropylene layer 5 make packaging film also have the feature of high transparent and deflection, in addition, adhesive layer 3 is modified polyethylene material, and can improve polyethylene and polyacrylic compatibility, bonding effect is more firm between layers, not easily layering, the yield rate of packaging film is higher.And packaging film of the present utility model is thicker, improve bulk strength and the molding effect of packaging film, packaging film can not produce gauffer.
