Abstract
The utility model discloses a kind of winding film with air hole, including a main film, and some row air holes are offered in said primary membrane, are also equipped with some reinforcing ribs side by side in said primary membrane, and one layer of muscle overlay film is covered with the reinforcing rib.For this programme compared with existing common winding film, it can not only play the role of the fixed cargo of protection, also increase winding dynamics, strengthen the fixation support force to cargo.Additionally it is possible to it is ventilative, it is especially more effective to the fresh protection for waiting specialities.
Description
Technical field
It the utility model is related to winding technical field of membrane, more particularly to a kind of winding film with air hole.
Background technology
Film is wound, is called stretched film, is a kind of common film material for being used to protect cargo, its base material is with LLDPE
Based on, and carry tack.In use, film can be wound by film superpower winding power and nerve by the winding of multilayer,
Cargo compactly, is regularly bundled into a unit, and gives cargo protection and fixes.
However, in some special cargo protections, such as the fresh-keeping cargo such as fresh, cold chain, fresh flower, water fruits and vegetables, its
Both needed to produce fixed force to cargo, and prevented from collapsing, and needed ventilative.But existing common winding film is after packaging, cargo
Inside and outside airtight, when long-time storage, transport, environment temperature and big humidity difference, cargo can add in sealed states
The speed damage or damage of cargo, causes loss.If poking winding film to breathe freely, winding film strength can be destroyed, is caused
Film integrally ruptures, and reduces protecting effect of the winding film to cargo.
Utility model content
The purpose of this utility model is：It is proposed a kind of winding film with air hole, it can either breathe freely, and can keep twining
Around the integral strength of film.
Technical solution is used by the utility model solves its technical problem：
A kind of winding film with air hole, including a main film, offer some row air holes, the master in said primary membrane
Some reinforcing ribs are also equipped with film side by side, and one layer of muscle overlay film is covered with the reinforcing rib.
Further, equidistant arrangement between the air hole.
Further, it is respectively equipped with a reinforcing rib between two rows of the air hole.
Further, said primary membrane is made of linear low density polyethylene material.
Further, the reinforcing rib is in thread like body, and using the material identical with main film or using polyamide fibre, terylene, nylon
It is made with composite material.
Further, the muscle overlay film is in strip, and is made of the material identical with said primary membrane.
Further, the thickness of said primary membrane, reinforcing rib and muscle overlay film is 10um.
The beneficial effects of the utility model are：For this programme compared with existing common winding film, it can not only play guarantor
The effect of the fixed cargo of shield, also increases winding dynamics, strengthens the fixation support force to cargo.Additionally it is possible to it is ventilative, especially
It is more effective to the fresh protection for waiting specialities.

Embodiment
Below in conjunction with attached drawing.The utility model is described further.
The specific implementation structure of the utility model is as shown in Figure 1, including main film 1, air hole 2, reinforcing rib 3 and muscle overlay film 4；
Wherein, air hole 2 is opened on main film 1, and mutual equidistant arrangement, and can be set up in parallel some rows on a main film 1 breathes freely
Hole 2.
Reinforcing rib 3 is in thread like body, and is attached on the one side of main film 1, concretely, one is set between two row air holes 2
Bar reinforcing rib 3.
In addition, one layer of muscle overlay film 4 is also covered with reinforcing rib 3, and the muscle overlay film 4 is in strip.
Main film 1 is made of linear low density polyethylene material.
Reinforcing rib 3 is made using the material identical with main film 1 or using polyamide fibre, terylene, nylon and composite material.
Muscle overlay film 4 is made of the material identical with main film 1.
The thickness of main film 1, reinforcing rib 3 and muscle overlay film 4 is 10um.
The process of the utility model is as shown in Fig. 2, a roll of main film 1 is unfolded by unwinding equipment 11, by muscle mould processed
Tool 12 covers reinforcing rib 3 on main film 1, then a muscle overlay film 4 is covered on reinforcing rib 3, and then passes through opening die 13
The perforate on main film 4, finally, is wound manufactured winding film by winding device 14.
When the utility model is used, the manufactured winding film with air hole is drawn by the way that wrapping machine 5 need to be first passed through
Hole, as shown in Figures 3 and 4, air hole is saturating for perforate state by closed pore state air hole 21, stretched expansion for the process of its pulling eye
The winding film 6 with air hole, is then wrapped on cargo 7 by stomata 22.
The advantages of basic principle and main feature and this programme of this programme has been shown and described above.The technology of the industry
Personnel are it should be appreciated that this programme is not restricted to the described embodiments, and the above embodiments and description only describe this
The principle of scheme, on the premise of this programme spirit and scope are not departed from, this programme also has various changes and modifications, these changes
Change and improve and both fall within the range of claimed this programme.This programme be claimed scope by appended claims and its
Equivalent thereof.
