Description

Portable winding film

Technical Field

The utility model belongs to the technical field of the winding membrane technique and specifically relates to a portable winding membrane is related to.

Background

Winding films, also called stretch films and heat shrink films, are mainly used for stabilizing and protecting articles, and after wrapping the articles with the winding films, the articles are often required to be transferred. In the prior art, the film is easy to pull longer when the winding film is torn, the end of the winding film is not easy to find, and the winding film is inconvenient to use next time.

In addition, when fresh goods such as fruit twine, the winding membrane tightly wraps up in the fruit outside for inside and outside airtight of goods, under the condition that long-time storage, transportation, ambient temperature and humidity difference are big, the goods can be under encapsulated situation, and the damage or the damage of goods with higher speed causes the loss.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a portable winding membrane, simple structure, intensity is high, and the gas permeability is good, the packing of being convenient for.

In order to realize the above object, the utility model provides a portable winding membrane, which comprises a body, the body including ventilative layer with set up in enhancement layer between the ventilative layer, the middle part on enhancement layer surface is equipped with the bleeder vent that is regular triangle distribution, tear the solenoid on the body include the broken line portion and set up in first connecting portion, the second connecting portion at broken line portion both ends, first connecting portion with the second connecting portion are squarely, and distribute and be in the both sides of tear the line.

Preferably, the air holes comprise an upper row of air holes and a lower row of air holes, and the distances between the upper row of air holes and the adjacent air holes on the lower row of air holes are equal and are distributed in a regular triangle.

Preferably, the first connecting portion and the second connecting portion are connected to the peak of the broken line portion.

Preferably, the folding line part is a circularly arranged folding line structure.

Preferably, the material of the breathable layer is transparent breathable polyurethane.

Preferably, the material of the reinforcing layer is transparent plastic.

Therefore, the utility model adopts the above-mentioned portable winding membrane, simple structure, intensity is high, and the gas permeability is good, the packing of being convenient for.

The technical solution of the present invention is further described in detail by the accompanying drawings and examples.

Description of the reference numerals

1. A body; 2. a breathable layer; 3. a reinforcing layer; 4. air holes are formed; 5. tearing the line; 6. a fold line portion; 7. A first connection portion; 8. a second connecting portion; 9. an upper row of air holes; 10. and air holes are arranged at the lower part.

Detailed Description

The technical solution of the present invention is further explained by the accompanying drawings and examples.

Unless defined otherwise, technical or scientific terms used herein shall have the ordinary meaning as understood by those of ordinary skill in the art to which the invention belongs. The use of "first," "second," and similar terms in the description herein do not denote any order, quantity, or importance, but rather the terms are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the element or item listed before the word covers the element or item listed after the word and its equivalents, but does not exclude other elements or items. The terms "connected" or "coupled" and the like are not restricted to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.

As shown in the figure, a portable winding membrane, including body 1, body 1 includes ventilative layer 2 and sets up in ventilative enhancement layer 3 between layer 2, and the material on ventilative layer 2 is transparent ventilative polyurethane, and the material on enhancement layer 3 is transparent plastic, and ventilative layer 2 and enhancement layer 3 are synthetic type of heat as an organic whole.

The middle part on 3 surfaces of enhancement layer is equipped with the bleeder vent 4 that is regular triangle distribution, and the holistic bearing strength can be improved to enhancement layer 3, and simultaneously, ventilation function can be realized to bleeder vent 4, prevents to give birth to under the high temperature, the high humid circumstances of bright, improves corrupt effect. The air holes 4 comprise an upper row of air holes 9 and a lower row of air holes 10, and the distances between the upper row of air holes 9 and the adjacent air holes 4 on the lower row of air holes 10 are equal and are distributed in a regular triangle. The overall arrangement of the air holes 4 can ensure the bearing strength of the reinforcing layer 3 while realizing the effective ventilation of the whole body.

The tearing line 5 on the body 1 comprises a folding line part 6, a first connecting part 7 and a second connecting part 8 which are arranged at two ends of the folding line part 6, and the folding line part 6 is a circularly arranged folding line structure. The first connecting portion 7 and the second connecting portion 8 are both square and distributed on two sides of the tearing line 5. The first connecting portion 7 and the second connecting portion 8 are connected with the peak of the fold line portion 6 at the highest point, so that the fold line portion 6 and the first connecting portion 7 or the second connecting portion 8 are prevented from being torn in the pulling process.

The utility model discloses a when the winding membrane used, after accomplishing the winding membrane winding, torn first connecting portion 7 earlier in suitable position, then realized that the tear line of epilogue tears in proper order. Meanwhile, if a certain part of the tear line 5 is broken, the first connecting part 7 or the second connecting part 8 which are arranged in a front-back separation mode can still be connected with the next section of the body, and the situation that the body 1 is broken due to the fact that a certain section of the tear line 5 is cracked cannot be caused. In addition, the first connecting part 7, the second connecting part 8 and the broken line part 6 generate a plurality of breakpoints, so that the opening section can be found conveniently in the next use.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
