Description
[technical field]
The utility model relates to the technical field of packing explosive film, particularly the technical field of packet packaging film in a kind of upper blowing method explosive.
[background technology]
Middle packet packaging film many employings PE/PP co-extrusion lower blowing method that current packing explosive field uses is produced, better merge for making two kinds of opposed polarity materials, it is made not occur lamination when sealing, need to add a certain amount of adhesive in intermediate layer, thus make both well combine by opposed polarity material, form three-decker.But the middle packet packaging film that this kind of method is produced differs greatly due to intermediate layer adhesive and PE and PP processing temperature, cause fluidity of molten to fluctuate comparatively large, process more difficult, the more difficult control of the film thickness uniformity of blowing; Secondly, because binding agent price is higher, production cost is higher, and waste material is difficult to recycle and barrier is poor.
[utility model content]
The purpose of this utility model solves the problems of the prior art exactly, proposes packet packaging film in a kind of upper blowing method explosive, and packing explosive film dynamic performance can be made better, deflection is larger simultaneously, and easily produce, packing explosive film thickness uniformity is good, production cost is lower, and production efficiency is higher.
For achieving the above object, the utility model proposes packet packaging film in a kind of upper blowing method explosive, comprise LDPE layer, MPE layer, HDPE layer, copolymerization PP layer and homopolymerization PP layer, projection is respectively arranged with inside described LDPE layer and homopolymerization PP layer, MPE layer, HDPE layer and copolymerization PP layer is provided with between described LDPE layer and homopolymerization PP layer, described MPE layer, HDPE layer and copolymerization PP layer both sides are respectively arranged with projection, the thickness of described LDPE layer and homopolymerization PP layer is respectively 15 μm-20 μm, and the thickness of described MPE layer, HDPE layer and copolymerization PP layer is respectively 30 μm-40 μm.
As preferably, the thickness of described LDPE layer is 18 μm.
As preferably, the thickness of described homopolymerization PP layer is 20 μm.
As preferably, the thickness of described MPE layer is 20 μm.
As preferably, the thickness of described HDPE layer is 30 μm.
As preferably, the thickness of described copolymerization PP layer is 25 μm.
The beneficial effects of the utility model: the utility model is by being applied in packing explosive film by LDPE layer, MPE layer, HDPE layer, copolymerization PP layer and homopolymerization PP layer, packing explosive film dynamic performance can be made better, deflection is larger simultaneously, easy processing, packing explosive film thickness uniformity is good, production cost is lower, and production efficiency is higher.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
[accompanying drawing explanation]
Fig. 1 is the front view of packet packaging film in a kind of upper blowing method explosive of the utility model.
In figure: 1-LDPE layer, 2-MPE layer, 3-HDPE layer, 4-copolymerization PP layer, 5-homopolymerization PP layer.
[detailed description of the invention]
Consult Fig. 1, packet packaging film in a kind of upper blowing method explosive of the utility model, comprise LDPE layer 1, MPE layer 2, HDPE layer 3, copolymerization PP layer 4 and homopolymerization PP layer 5, projection is respectively arranged with inside described LDPE layer 1 and homopolymerization PP layer 5, MPE layer 2 is provided with between described LDPE layer 1 and homopolymerization PP layer 5, HDPE layer 3 and copolymerization PP layer 4, described MPE layer 2, HDPE layer 3 and copolymerization PP layer 4 both sides are respectively arranged with projection, described protruding close-packed arrays, project through and extrude at the opposite side of film with pressure roller, pressure roller is provided with hemispherical projections, the thickness of described LDPE layer 1 and homopolymerization PP layer 5 is respectively 15 μm-20 μm, described MPE layer 2, the thickness of HDPE layer 3 and copolymerization PP layer 4 is respectively 30 μm-40 μm.The thickness of described LDPE layer 1 is 18 μm.The thickness of described homopolymerization PP layer 5 is 20 μm.The thickness of described MPE layer 2 is 20 μm.The thickness of described HDPE layer 3 is 30 μm.The thickness of described copolymerization PP layer 4 is 25 μm.
Packet packaging film in a kind of upper blowing method explosive of the utility model, by LDPE layer 1, MPE layer 2, HDPE layer 3, copolymerization PP layer 4 and homopolymerization PP layer 5 are applied in packing explosive film, packing explosive film dynamic performance can be made better, deflection is larger simultaneously, easy processing, packing explosive film thickness uniformity is good, and production cost is lower, and production efficiency is higher.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
