Description

Stretch-proofing winding membrane

Technical Field

The utility model relates to the technical field of packaging films, in particular to a stretch-resistant winding film.

Background

As is well known, in recent years, with the continuous development of the production technology of the winding film, the application fields thereof are more and more extensive, including the aspects of packaging, sealing, rust prevention and the like of products. But for products with crisp texture, such as glass products, the packaging needs to be added with foam which has larger volume and is difficult to recycle. On one hand, the foam plastic has larger volume, so that the foam plastic occupies excessive transportation space; on the other hand, the foam plastic has low strength, so that the foam plastic needs to be sheathed with a packing box for protection, and the packing box needs to be sealed, thereby improving the packing cost. And the winding film has low cost and small thickness, so the defect of the foam plastic can be exactly compensated theoretically.

The stretch-proofing ability in the middle of the prior art winding film is very good, but the current extreme easy-to-draw of winding film edge is broken, through the retrieval, chinese patent with publication number CN209851751U discloses a novel winding film that stretch-proofing performance is good, including the winding film body, the surface of winding film body is provided with the strengthening rib that a plurality of parallels equidistant arranged, and the winding film body includes first winding film, net cloth and second winding film, and net cloth is located between first winding film and the second winding film, and first winding film includes antistatic backing, antirust coat, temperature-resistant layer and substrate layer, and first winding film and second winding film material are the same and in net cloth longitudinal symmetry. The reinforcing ribs are made of nylon, terylene, nylon and composite materials, the grid cloth is made of any one of nylon or cotton threads, and therefore the tensile resistance of the winding film is improved by the reinforcing ribs and the grid cloth.

In view of the above-mentioned related art, the inventor believes that there is a case where the reinforcing rib is made by setting nylon, terylene, nylon and composite material, and the stretch-proof property of the winding film is increased by setting the mesh cloth of any one material of nylon or cotton thread, so that the materials of the plurality of parts of the winding film are all cloth materials, thereby increasing the manufacturing cost of the winding film, and the elasticity of the winding film is very poor, so that the practicability of the winding film is lowered.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Aiming at the defects of the prior art, the utility model provides the stretch-resistant winding film, which can effectively improve the strength of the edge of the winding film, so that the winding film still has good elasticity, and the practicability of the winding film is effectively improved.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a stretch-proofing winding membrane, includes the winding membrane, and the left end and the right-hand member of winding membrane all are provided with the parcel layer, and the inside on every parcel layer all is provided with the stretching muscle, and the top and the bottom of winding membrane are provided with the waterproof layer, and the middle part of winding membrane is provided with antistatic backing.

Furthermore, the stretching rib is made of rubber.

Furthermore, the winding film and the wrapping layer are made of polyethylene.

(III) advantageous effects

Compared with the prior art, the utility model provides an anti-tensile winding film, which has the following beneficial effects:

this stretch-proofing winding membrane through the setting of parcel layer and tensile muscle, protects the edge of winding membrane, the effectual intensity that improves the winding membrane edge, makes the edge of winding membrane be difficult for being pulled apart, and the material of tensile muscle is rubber, makes this winding membrane still have good elasticity, has effectively improved the practicality of this winding membrane.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the stretch-resistant winding film disclosed by the utility model comprises a winding film 1, wherein wrapping layers 2 are respectively arranged at the left end and the right end of the winding film 1, the winding film 1 and the wrapping layers 2 are made of polyethylene and play a role of wrapping the stretching ribs 3, the stretching ribs 3 are respectively arranged inside each wrapping layer 2, the stretching ribs 3 are made of rubber, so that the winding film 1 still has good elasticity, the practicability of the winding film 1 is effectively improved, meanwhile, the wrapping layers 2 and the stretching ribs 3 protect the edges of the winding film, the strength of the edges of the winding film is effectively improved, the edges of the winding film are not easily pulled apart, waterproof layers 4 are arranged at the top and the bottom of the winding film 1 and play a waterproof role, and an antistatic layer 5 is arranged in the middle of the winding film 1 and plays an antistatic role.

To sum up, this stretch-proofing winding membrane, when using, utilize this stretch-proofing winding membrane 1 to carry out normal parcel to article, parcel layer 2 and tensile muscle 3 protect winding membrane 1's edge, the effectual intensity that improves winding membrane 1 edge makes winding membrane 1's edge be difficult for being pulled apart, the stay cord muscle makes this winding membrane 1 still have good elasticity, after winding membrane 1 accomplished article parcel, utilize sharp-pointed instruments such as scissors, knife will, tensile muscle 3, parcel layer 2 and winding membrane 1 cut apart can.
