Abstract
The utility model provides a kind of point off formula protective film, and it is disconnected to solve the problems, such as that protective film is not easy to draw in use；Including enhancement layer 1, base membrane layer 2, adhesive layer 3, clutch layer 4；It is characterized in that, the enhancement layer 1, base membrane layer 2, adhesive layer 3, the parallel connection successively of clutch layer 4；The base membrane layer 2 is provided with several breakpoint holes 21；The beneficial effects of the utility model are when in use, protective film can be torn by hand at breakpoint, facilitate tripping protection film, avoid using blade, reduce danger coefficient.Meanwhile the smooth beauty of cutout；Blocking distance also can voluntarily adjust.
Description
Technical field
The utility model is related to protect technical field of membrane more particularly to a kind of point off formula protective film.
Background technology
Protective film is mainly used for protecting article surface not contaminated in transport or process and scratch.Protective film exists
During use, it should be fitted in article surface, generally scratch protective film with blade, it is both inconvenient or dangerous in this way, and knife
It is also irregular that piece scratches end.
Invention content
The utility model provides a kind of point off formula protective film, solves protective film and is not easy to draw disconnected ask in use
Topic.
The utility model provides a kind of point off formula protective film, including enhancement layer 1, base membrane layer 2, adhesive layer 3, clutch layer 4；
It is characterized in that,
The enhancement layer 1, base membrane layer 2, adhesive layer 3, the parallel connection successively of clutch layer 4；
The base membrane layer 2 is provided with several breakpoint holes 21；
Preferably, the breakpoint hole 21 at least two arranges；
Preferably, the breakpoint hole 21 is uniform in size；
Preferably, the enhancement layer 1 further includes protrusion 11；Described raised 11 at least two row；
Preferably, each column protrusion 11 is corresponded with each column breakpoint hole 21；
Preferably, the adhesive layer 3 and the contact surface of clutch layer 4 are serrated；
Preferably, the contact surface of the clutch layer 4 and adhesive layer 3 is serrated；
Preferably, the serrated face of the adhesive layer 3 and the serrated face of clutch layer 4 cooperate；
Preferably, the adhesive layer（3）The one side being serrated is coated with adhesive.
The beneficial effects of the utility model are when in use, protective film can be torn by hand at breakpoint, facilitates tripping protection
Film avoids using blade, reduces danger coefficient.Meanwhile the smooth beauty of cutout.Blocking distance also can voluntarily adjust.
Description of the drawings
Fig. 1 is the utility model structural defence film；
Fig. 2 is base membrane layer breakpoint arrangement figure；
In figure,
1. enhancement layer, 11. protrusions；
2. base membrane layer, 21. breakpoints；
3. being stained with conjunction layer；
4. clutch layer.
Specific embodiment
This practicality is described in detail below in conjunction with the accompanying drawings, the description of this part is only exemplary and explanatory, is not answered
There is any restriction effect to the scope of protection of the utility model.
The utility model provides a kind of point off formula protective film, including enhancement layer 1, base membrane layer 2, adhesive layer 3, clutch layer 4；
The enhancement layer 1, base membrane layer 2, adhesive layer 3, the parallel connection successively of clutch layer 4；
The base membrane layer 2 is provided with several breakpoint holes 21；
Preferably, the breakpoint hole 21 at least two arranges；
Preferably, the breakpoint hole 21 is uniform in size；
Preferably, the enhancement layer 1 further includes protrusion 11；Described raised 11 at least two row；
Preferably, each column protrusion 11 is corresponded with each column breakpoint hole 21；
Preferably, the adhesive layer 3 and the contact surface of clutch layer 4 are serrated；
Preferably, the contact surface of the clutch layer 4 and adhesive layer 3 is serrated；
Preferably, the serrated face of the adhesive layer 3 and the serrated face of clutch layer 4 cooperate.
In use, a part of point off formula protective film of first uncoiling, removes protective film by a part of clutch layer 4, protective film is pasted
On needing article to be protected, continue uncoiling, until institute's uncoiling part can will need article to be protected all packages, determining guarantor
Cuticula needs the position blocked, and protective film enhancement layer 1 corresponding raised 11 is torn a row according to this position, is torn at this time
The film strength of raised 11 positions is significantly lower than the intensity of other parts, and protrusion 11 it is corresponding be base membrane layer 2 breakpoint
Hole（21）, originally than film, the protective film of other non-breakpoint locations is weak for intensity, and intensity ratio more reduces before after tearing protrusion 11, institute
Only to need to find protrusion 11, after protrusion 11 is torn up, so that it may protective film is torn off film roll along breakpoint hole 21.
Above-described the utility model embodiment, does not constitute the restriction to scope of protection of the utility model.It is any
Modifications, equivalent substitutions and improvements made within spirit of the present utility model and principle etc., should be included in the utility model
Claims within.
