Abstract

The utility model relates to a polyester film which comprises a film body, a bending zone and a toothed trace; the bending zone is located on the film body; the tooted trace is located on the bending zone and is of a linear hole. According to the polyester film, the linear hole is formed in the bending zone, so that the polyester film can be bent along the linear hole; and through the arrangement, the polyester film can be more conveniently bent, and can not easily be broken after being bent, thereby being not frequently changed.

Description

A kind of polyester film

Technical field

The utility model relates to a kind of polyester film, and particularly a kind of easy bending, and polyester film not easy to crack after the bending belong to the polyester film product technical field.

Background technology

Polyester film is a kind of water white transparency, glossiness film, and mechanical property is good, and rigidity, hardness and toughness are high, puncture, rub resistance, high temperature resistant and low temperature, chemical proofing, oil-proofness, resistance to air loss and fragrance protectiveness are good, are one of gas barrier laminated film base materials of commonly using; More and more be subject to consumers in general's favor because of its high comprehensive performance; But the turnout that China is present and state of the art still can not satisfying the market demand, especially film crack easily and disconnect in the part of bending, be difficult to process; The film that cracks or disconnect just need to be changed, and brings very large inconvenience to the user.

The utility model content

The utility model purpose is that a kind of easy bending is provided in order to overcome the deficiencies in the prior art, and polyester film not easy to crack after the bending.

For achieving the above object, the technical solution adopted in the utility model is: a kind of polyester film comprises film bulk, bent area, tooth trace; Described bent area is positioned on the film bulk; Described tooth trace is positioned on the bent area; Described tooth trace is the line style hole.

Preferably, the tooth trace on the described bent area has two.

Preferably, described two tooth traces are parallel to each other.

Preferably, described bent area has two, and two bent areas lay respectively on the upper edge and lower edge of polyester film.

Preferably, described tooth trace is the line style hole of dotted line shape; Described dotted line be spaced apart 0.5 millimeter.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

The polyester film of the utility model scheme is provided with the line style hole at bent area, so that polyester film can bend along the line style hole; The bending that is arranged so that polyester film like this is convenient, and is difficult for producing fracture after bending, does not need often to change polyester film.

Description of drawings

Below in conjunction with accompanying drawing technical solutions of the utility model are described further:

Accompanying drawing 1 is the front view of polyester film described in the utility model;

Wherein: 1, film bulk; 2, bent area; 3, tooth trace.

Embodiment

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

As shown in Figure 1, a kind of polyester film described in the utility model comprises film bulk 1, bent area 2, tooth trace 3; Described bent area 2 has two, and two bent areas 2 lay respectively on the upper edge and lower edge of film bulk 1; Be provided with two tooth traces that are parallel to each other 3 on described each bent area 2; Described tooth trace 3 is the line style hole of dotted line shape; Described dotted line be spaced apart 0.5 millimeter.

Because the utilization of technique scheme, the utility model compared with prior art has following advantages:

The polyester film of the utility model scheme is provided with the line style hole at bent area, so that polyester film can bend along the line style hole; The bending that is arranged so that polyester film like this is convenient, and is difficult for producing fracture after bending, does not need often to change polyester film.

Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, all drop within the utility model rights protection scope.
