Description
Technical Field
The utility model relates to a winding membrane technical field specifically is a high strength winding membrane.
Background
A winding film, also called a stretch film, is a common film material for protecting goods, and the base material of the winding film is mainly LLDPE and has self-adhesiveness. When the device is used, goods can be compactly and fixedly bundled into a unit by virtue of the winding force and retractility of the film, and the goods can be protected and fixed by virtue of the winding of multiple layers and the winding film;
a high-strength winding film with the publication number of CN208700951U discloses that reinforcing nets which are formed by weaving and bonding 12 mu m-diameter fiber yarns made of elastic polyurethane rubber are arranged in a reinforcing layer I and a reinforcing layer II, and the strength of the whole winding film after being punctured can be ensured through the reinforcing nets;
however, the wound film still belongs to a sealed wound film, and the wound film is only punctured to ventilate when in use, and if no hard object is punctured when in use, the wound film cannot ventilate.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a high strength winding membrane to solve the winding membrane and just stab it when using and breathe freely, do not have hard thing to stab when using and tear, then can lead to the winding membrane can't carry out ventilative weak point.
In order to achieve the above object, the present invention provides the following technical solutions: including two-layer winding membrane main part, it is two-layer be provided with the flexible layer of two-layer mutual laminating between the winding membrane main part, it is two-layer the arc wall that runs through its opposite side is all seted up to one side of flexible layer, the radian of arc wall is 180, and is two-layer arc wall on the flexible layer is crisscross each other and mutually supports and is circular distribution.
Preferably, two-layer the bleeder vent that runs through the opposite side is seted up to one side of winding membrane main part, the arc wall all sets up between the bleeder vent.
Preferably, the two layers of the winding film main bodies are provided with glue layers on the sides close to each other.
Preferably, the whole air hole is in a straight notch shape.
Compared with the prior art, the utility model provides a pair of high strength winding membrane has seted up the bleeder vent through the winding membrane main part, lies in the arc wall that has seted up in the bleeder vent coplanar on the flexible layer for wholly be airtight type when normal use, be ventilative type when pulling the deformation after the winding hard.

Detailed Description
In order to make the technical solution of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings.
Please refer to fig. 1-5, the embodiment of the utility model provides a high strength winding membrane, including two-layer winding membrane main part 1, winding membrane main part 1 is prior art, be provided with two-layer flexible layer 3 of laminating each other between the two-layer winding membrane main part 1, flexible layer 3 has the ductility, can cooperate winding membrane main part 1 to carry out corresponding extension when dragging the extension, arc 31 that runs through its opposite side is all seted up to one side of two-layer flexible layer 3, the radian of arc 31 is 180, arc 31 on the two-layer flexible layer 3 is crisscross each other and mutually supports and be circular distribution, when dragging the extension and warp, arc 31 can coincide each other and the opening grow, it is ventilative, and through being provided with two-layer winding membrane main part 1, the cooperation of both sides flexible layer 3, make wholly be multilayer structure, increase and drag intensity.
One side of the two layers of winding film main bodies 1 is provided with air holes 11 penetrating the other side, and the arc-shaped grooves 31 are all arranged between the air holes 11.
One side that two-layer winding membrane main part 1 was close to each other all is provided with glue film 2.
The whole air hole 11 is in a straight notch shape.
When the winding film is normally used, the winding film main body 1 only needs to be normally wound on an object, and the winding film main body does not need to be pulled forcefully to deform;
when needing to make it ventilative, only need pull winding membrane main part 1 hard and warp for arc groove 31 warp the opening and increase, and what the individual layer winding can be convenient on the object is ventilative afterwards.
While certain exemplary embodiments of the present invention have been described above by way of illustration only, it will be apparent to those of ordinary skill in the art that the described embodiments may be modified in various different ways without departing from the spirit and scope of the present invention. Accordingly, the drawings and description are illustrative in nature and should not be construed as limiting the scope of the invention.
