Abstract
The utility model discloses a protective film easy to tear and stick, which relates to tearing components of the protective film of a liquid crystal display and a mobile phone screen in a process. The protective film comprises the protective film and a release type film and further comprises a tearing handle arranged on the protective film. The protective film is the protective film with the tearing handle, so that users can quickly and easily find the portion where users can tear and strip the protective film. The color of the tearing handle can have slight color or obvious color, so that the users can find the tearing handle quickly and easily in a large transparent protective film and strip the protective film conveniently.
Description
Technical field
The present invention relates to the parts that tear off that liquid crystal display and mobile phone shield protective membrane during the course.
Background technology
For preventing that factors such as liquid crystal display and mobile phone screen accident in the manufacture craft process suffers to rub, touch from causing screen scratch or foreign matter, so liquid crystal display and mobile phone screen need use protective membrane protection during the course.
Because protective membrane belongs to the process materials, when flowing into next link, need tear off, because protective membrane has viscosity; Directly be fitted in above the screen; When tearing off, relatively lose time, because when peeling off, need on the corner of protective membrane, seek the place that to tear, so that peel off; And the applying of protective membrane is tighter, sometimes is difficult on the corner of protective membrane and finds the place that is prone to peel off.
The utility model content
The purpose of the utility model provides a kind of protective membrane that is prone to tear subsides, reduces liquid crystal display and mobile phone and shields in the manufacture craft consumed time and cost when tearing off protective membrane.
The technical scheme of the utility model is: a kind ofly be prone to tear pasting protective film, comprise protective membrane and dicing film, also comprise protective membrane and be positioned at the hand that tears on the protective membrane.
The described hand that tears is wherein a part of peripheral part that is bonded in protective membrane, and its cohesive force is greater than the cohesive force of protective membrane and dicing film.
Involved protective membrane is that liquid crystal display and mobile phone screen shield in making processes in the such scheme, and protective membrane commonly used is divided into PET protective membrane, PE protective membrane, PVC protective membrane.
Protective membrane in the such scheme is meant and on base material, is coated with the last layer glue paste, makes it can be attached to the surface that will protect product.Wherein acceptable substrate is divided into the PET base material, PE base material, PVC base material.Related PET is meant one deck polyethylene terephthalate in this programme, is called for short PET, and PE related in this programme is meant sealed polyethylene plastic, and PVC related in this programme is meant SE.
Beneficial effect:
(1) the utility model is to have the protective membrane that tears hand, is convenient to find peelable position fast, peels off protective membrane.
The color of (2) tearing hand can have color or significantly, more is prone in transparent big protective membrane, find fast and tears hand, is convenient to peel off.
Description of drawings
Fig. 1 is the synoptic diagram of the utility model.
Fig. 2 is the hand that tears of the utility model.
Wherein: the 1-protective membrane; The 2-dicing film; 3-tears hand.
Embodiment
Embodiment 1
As depicted in figs. 1 and 2, a kind ofly be prone to tear pasting protective film, comprise that protective membrane 2 tears hand 3 with being positioned on the protective membrane.
Embodiment 2
As depicted in figs. 1 and 2, a kind ofly be prone to tear pasting protective film, comprise that protective membrane 1 tears hand 3 with being positioned on the protective membrane 1.The described hand 3 that tears is wherein a part of peripheral parts that are bonded in protective membrane 1, and its cohesive force is greater than the cohesive force of protective membrane 1 with dicing film 2.
Band tears the protective membrane 1 of hand 3, and the described hand 3 that tears is to be processed by adhesive tape, and adhesive tape is divided into single face adhesive tape and double sticky tape, and wherein the single face adhesive tape is meant at coated with adhesive of a kind of base material, makes it have only one side to have adhesive effect.Double sticky tape is meant the coated with adhesive on a kind of base material two sides, makes its two sides all have adhesive effect.
Relatedly in this programme tear the peripheral part that part surface with glue that hand 3 is meant the single face adhesive tape that size is little fits in non-tackiness agent on the protective membrane 1; Another part is pasted each other; Form the non-adhesive part, guarantee that like this this position of tearing hand 3 does not all have tackiness agent up and down.The main purpose that the non-adhesive part of hand 3 is torn in design is to prevent up and down products with adhesive together on the one hand, is bonding and be difficult for taking off when preventing to tear off on the other hand.
If double sticky tape need not have the effect of glue to reach this face in the another side applying one deck dicing film 2 or the separate-type paper of applying single face adhesive tape.
Tear off at needs under the situation of protective membrane, directly mention and tear hand 3 positions, promptly can whole protective membrane 1 be torn off.
As depicted in figs. 1 and 2, selecting thickness for use is 0.05 mm PET, makes up protective membrane 1 base material, and on the PET base material, being coated with last layer thickness is 0.01 mm tackiness agent, makes up tackiness agent;
With the single face adhesive tape is example, and selecting thickness for use is 0.05 mm PET (color is arranged), makes up adhesive band base, and on adhesive band base, simultaneously being coated with last layer thickness is 0.01 mm tackiness agent, makes up tackiness agent;
Have tackiness agent simultaneously to fit on 2 volume single face adhesive tapes, wherein 1 volume single face adhesive tape is very little bigger than another tape measure, and upper and lower surface is the non-adhesive zone;
Embodiment 4
As depicted in figs. 1 and 2, selecting thickness for use is 0.05mm PET, makes up protective membrane 1 base material, and on the PET base material, being coated with last layer thickness is 0.01 mm tackiness agent, makes up tackiness agent;
With the double sticky tape is example, and selecting thickness for use is 0.075 mm PET, makes up adhesive band base, and respectively to be coated with last layer thickness be 0.0375 mm tackiness agent on the two sides on adhesive band base, makes up tackiness agent;
There are tackiness agent one side and double sticky tape to fit on the single face adhesive tape, double sticky tape another side applying dicing film 2 or separate-type paper, wherein double sticky tape is bigger than single face adhesive tape size, and upper and lower surface is the non-adhesive zone;
Claims (3)
1. one kind is prone to tear pasting protective film, comprises protective membrane and dicing film, it is characterized in that: also be included in the hand that tears on the protective membrane.
2. according to claim 1ly be prone to tear pasting protective film, it is characterized in that: the described hand that tears is wherein a part and protective membrane bonding, and its cohesive force is greater than the cohesive force of protective membrane and dicing film.
3. according to claim 1ly be prone to tear pasting protective film, it is characterized in that: describedly tear the periphery that hand is positioned at protective membrane.
