Abstract
The utility model discloses an easily-torn polymer film which comprises a sealing part, wherein the sealing part is provided with a plurality of concave points and/or convex points; the easily-torn polymer film is simple in structure and convenient to manufacture; as the concave points and/or the convex points are adopted, the phenomenon that two or more films are heat-sealed on one packaging container during the actual packaging process is avoided; and therefore, the packaging effect is improved, and the packaging defective percentage is reduced.
Description
Technical field
The utility model relates to packaging field, is specifically related to a kind of poly-mer easily tore film.
Background technology
Easily tore film can avoid packaged articles to contact with aqueous vapor with airborne oxygen by actv. because of its good leak tightness and easy-to-rupture, is widely used in the various food and medicine sealed packages.Poly-mer easily tore film commonly used is ganoid sheet, it is lighter to conduct oneself with dignity, when the production of poly-mer easily tore film, storage, use, as contact aqueous vapor or electrostatic interaction can cause close adhesion between easily tore film sheet and the sheet, so that two of appearance or multi-disc film are heat-sealed to a phenomenon on the packaging container in the actual package process, and packaging effect is undesirable.Therefore, be necessary existing poly-mer easily tore film is carried out structural development.
The utility model content
The purpose of this utility model is to overcome the defective that exists in the prior art, and the poly-mer easily tore film of good separating effect between a kind of and the sheet is provided, and can avoid two or multi-disc film to be encapsulated into a phenomenon on the container.
For achieving the above object, the technical solution of the utility model is: a kind of poly-mer easily tore film, described easily tore film comprises sealing, it is characterized in that, is provided with several concave points and/or salient point on the described sealing.
For the unlatching of convenient heat-sealing easily tore film, preferred technical scheme is, described easily tore film also comprises tearing section, and described tearing section is connected with the edge of sealing, and described tearing section is at least one.
In order to increase the friction force of tearing section, make things convenient for simultaneously the integrated production of sealing and tearing section, preferred technical scheme is, is provided with several salient points and/or concave point in the described tearing section.
In order to rationalize the easily tore film structure, preferred technical scheme is, described tearing section be semicircle, and the diameter of described semicircle tearing section is connected with sealing.
In order to rationalize the easily tore film structure, preferred technical scheme can also for, described tearing section and described sealing are connected smoothly, the outer rim of described tearing section is fillet.
When the easily tore film tearing section of a side and sealing junction when damaging, conveniently open easily tore film from opposite side, preferred technical scheme is, two at described tearing position, described tearing section is symmetrical arranged along the edge of described sealing.
For the Applicable scope that makes the poly-mer easily tore film enlarges, preferably technical scheme is, described sealing is circle, ellipse or polygon, and described polygonal angle is fillet.
In order to make heat seal process convenient and swift, save the inconvenience of heat-sealing gluing, preferred technical scheme is that upper surface or the lower surface of described easily tore film are provided with hot melt adhesive layer.
In order to guarantee that easily tore film can be applicable to the requirement of food and medicine aseptic packaging, preferred technical scheme is that the material of described easily tore film is poly terephthalic acid class plastics.
Advantage of the present utility model and beneficial effect are:
This poly-mer easily tore film is simple in structure, easily manufactured, adopts concave point and/or salient point, guarantees not occur two or multi-disc film and be heat-sealed to a phenomenon on the packaging container in the actual package process, improves packaging effect, reduces the encapsulation fraction defect.
Description of drawings
Fig. 1 is the birds-eye view of the utility model poly-mer easily tore film;
Fig. 2 is that Fig. 1 is along the section-drawing of A-A ' direction;
Fig. 3 is the birds-eye view of the another kind of embodiment of the utility model poly-mer easily tore film;
Fig. 4 is that Fig. 1 is along the section-drawing of B-B ' direction.
Among the figure: 1, sealing; 2, tearing section; 3, concave point; 4, salient point; 5, hot melt adhesive layer.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
As depicted in figs. 1 and 2, present embodiment is a kind of poly-mer easily tore film, comprises sealing 1, is provided with several concave points 3 and salient point 4 on the sealing 1.
In the present embodiment, easily tore film also comprises tearing section 2, and tearing section 2 is connected with the edge of sealing 1.
In the present embodiment, be provided with several salient points 4 and concave point 3 in the tearing section 2.
In the present embodiment, tearing section 2 is connected smoothly with sealing 1, and the outer rim of tearing section 2 is fillet.
In the present embodiment, the lower surface of easily tore film is provided with hot melt adhesive layer 5.
In the utility model, sealing 1 is circular.
As shown in Figure 3 and Figure 4, present embodiment is a kind of poly-mer easily tore film, and easily tore film comprises sealing 1, is provided with several concave points 3 on the sealing 1.
In the present embodiment, easily tore film also comprises tearing section 2, and tearing section 2 is connected with the edge of sealing 1, and tearing section 2 is at least one.
In the present embodiment, be provided with several concave points 3 in the tearing section 2.
In the present embodiment, tearing section 2 is semicircle, and the diameter of semicircle tearing section 2 is connected with sealing 1.
In the present embodiment, 2 two in tearing section, tearing section 2 is symmetrical arranged along the edge of sealing 1.
In the present embodiment, the lower surface of easily tore film is provided with hot melt adhesive layer 5.
In the present embodiment, sealing 1 rectangle, four angles of rectangle are fillet.
Salient point and concave point are irregular setting, and therefore, be following state between easily tore film sheet and the sheet in use: the salient point of lower floor contacts with the concave point on upper strata or plane, and the levels contact surface is little, and levels is easier separately during heat-sealing.
The above only is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
