Abstract
The invention relates to a heat shrinking film. The heat shrinking film is used for shrink-wrapping the surface of a box. The opening dimension of the heat shrinking film is larger than the perimeter of width and height dimension of the box by a preset value. The heat shrinking film is provided with vent holes which are distributed uniformly. Using the technical scheme, after heat shrinkage, the heat shrinking film fits tightly with the box, and the heat shrinking film is smooth and does not have wrinkles.
Description
Technical field
The present invention relates to packing box technical field, particularly relate to heat shrinkage film.
Background technology
At present, heat shrinkage film is that client takes first material touched of product, not only wants material requirement
Smooth sense of touch is good, also requires outward appearance neat in edge.On the most front market, pyrocondensation molding effect is uneven, for
Guarantee pyrocondensation effect meets uniform requirement, it is impossible to cut occur, steam vent can not deform, edge joint
Can not bend, it is impossible to angle of rest (repose).
Summary of the invention
The embodiment of the present invention provides heat shrinkage film.Described technical scheme is as follows:
A kind of heat shrinkage film, it is characterised in that described heat shrinkage film for pyrocondensation in box surface, wherein, institute
State heat shrinkage film opening size high-dimensional Zhou Chang great preset value wider than described box body, described heat shrinkage film has
Equally distributed steam vent.
In the present embodiment, the size mated with box body by heat shrinkage film, and the perforate mode on film surface,
After guaranteeing pyrocondensation, heat shrinkage film is with box body laminating closely, the smooth corrugationless of effect.
Optionally, described preset value is 4 millimeters.
In alternative, by arrange heat shrinkage film opening size than box body wide high-dimensional Zhou Chang great 4 milli
Rice so that box body easily packs and is difficult to fold after pyrocondensation.
Optionally, described heat shrinkage film corner cuts, and every cutting line is corresponding with the four of described box body ribs,
After making pyrocondensation, described heat shrinkage film is fitted with the four sides of each rib of described box body, and each cutting line is positioned at
On the rib that described box body is corresponding.
In alternative, cut by heat shrinkage film corner, every cutting line and four ribs of described box body
After corresponding pyrocondensation, heat shrinkage film is fitted with the four sides of each rib of box body, and each cutting line is positioned at described box body
On corresponding rib, the appearance of fold after pyrocondensation can be reduced further, edge joint do not have bending,
Angle of rest (repose), after pyrocondensation, box body is hexahedro smooth.
It should be appreciated that it is only exemplary and explanatory that above general description and details hereinafter describe
, the present invention can not be limited.

Detailed description of the invention
Here will illustrate exemplary embodiment in detail, its example represents in the accompanying drawings.Following retouches
Stating when relating to accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represents same or analogous and wants
Element.Embodiment described in following exemplary embodiment does not represent own consistent with the present invention
Embodiment.On the contrary, they only with as appended claims describes in detail, the present invention some
The example of the apparatus and method that aspect is consistent.
The present invention proposes a kind of scheme, the size mated by heat shrinkage film, and the perforate on film surface with box body
Mode, it is ensured that the smooth corrugationless of effect after pyrocondensation.
Fig. 1 is the schematic diagram of the heat shrinkage film in the embodiment of the present invention and box body, as it is shown in figure 1, heat shrinkage film 11
For pyrocondensation in box body 12 surface.
Fig. 2 is the schematic diagram of the heat shrinkage film opening size in the embodiment of the present invention, as in figure 2 it is shown, wherein, and heat
The Zhou Chang great preset value of contracting film 11 opening 21 size wider than described box body 12 high-dimensional 22.
Preferably, this preset value is 4 millimeters.If this preset value is more than 4 millimeters, the easy pleat of heat shrinkage film after pyrocondensation
Wrinkle, such as the then box body difficulty pack less than 4 millimeters of this preset value.
Fig. 3 is the schematic diagram of the heat shrinkage film upper air-vent in the embodiment of the present invention, as it is shown on figure 3, heat shrinkage film 11
On there is equally distributed steam vent 31.Steam vent equal proportion is distributed in each plane, it is ensured that in pyrocondensation
Uniform aerofluxus in journey so that during pyrocondensation, heat shrinkage film cutting line is difficult to explosion.
Fig. 4 is the schematic diagram that the heat shrinkage film corner in the embodiment of the present invention cuts, as shown in Figure 4, the present embodiment
In, heat shrinkage film corner cuts, and every cutting line is corresponding with the four of described box body ribs.As cutting line 411,
412,413,414 is corresponding with the four of box body ribs respectively.
Fig. 5 is the effect schematic diagram after the pyrocondensation in the embodiment of the present invention, as it is shown in figure 5, heat shrinkage film after pyrocondensation
Fit with the four sides of each rib of box body, and each cutting line is positioned on the rib that described box body is corresponding, permissible
The appearance of fold after minimizing pyrocondensation further, edge joint does not haves bending, angle of rest (repose), box body after pyrocondensation
Hexahedro smooth.
Fig. 6 is the schematic diagram of the box body in the embodiment of the present invention, as shown in Figure 6, and the upper cover of box body 12
After buckling, a gap 123 is had between 121 and box body 122.Therefore, as it is shown in figure 5, this heat shrinkage film
On also have and butt line 51, corresponding to this gap.So, the box body after subsequent user takes this pyrocondensation
After, it is convenient to butt line by this and open heat shrinkage film.
The heat shrinkage film of the embodiment of the present invention, the size mated with box body by heat shrinkage film, and heat shrinkage film
The perforate mode on film surface, it is ensured that the smooth corrugationless of effect after pyrocondensation, improves pyrocondensation effect.It addition,
By cutting in heat shrinkage film corner, cutting line is corresponding with the rib of box body, further fold after minimizing pyrocondensation
Occur so that after pyrocondensation, each surface of box body is the most smooth.
Those skilled in the art, after considering description and putting into practice disclosure disclosed herein, will readily occur to this
Other embodiment of invention.The application is intended to any modification, purposes or the adaptability of the present invention
Change, these modification, purposes or adaptations are followed the general principle of the present invention and include this
