Breathable substrate layer
The material of the breathable substrate layer is Polyethylene (PE).
Include by first substrate layer and the second substrate layer that the table is range upon range of to the lining in proper order, the aperture of second substrate layer bleeder vent is greater than the aperture of first substrate layer bleeder vent, the second substrate layer is close to by the thing of being pasted, when the glue film has the volatile matter, or under the high temperature and high humidity environment, gas or steam are in time discharged by the big gas port, effectively solve the protection film and swell the problem that leads to the adhesion strength variation, and the bleeder vent aperture of first substrate layer is little, effectively prevent external vapor from getting into, therefore, ventilative substrate layer has good ventilative structure and waterproof performance.
Light-peeling-force release film
Shows a release film having a release force of 20g or less.
Overweight release film
A release film having a release force of 100g or more.
The peeling force of the overweight release film is greater than that of the dust sticking film, so that the dust sticking film can be peeled off from the surface of the attached object through the overweight release film.
Overweight membrane thickness of leaving the type membrane is unanimous with the thick layer of ventilative substrate layer for the ventilative protection film concentric circles of rolling reduces the indentation, keeps the outward appearance planarization.
Dust sticking film
The protective film is connected with the protective film body along the rolling direction, firstly the light peeling force on the surface of the sticky film is torn off, the sticky film is pasted on the surface of a pasted object, powder particles or dust are timely pasted and removed, then the sticky film is torn off, meanwhile, the adhesive layer surface of the protective film body is pasted on the surface of the pasted object, and the problems that the protective film is bulged and is not pasted with the surface of the product due to unclean surface of the product are effectively solved.
The dust-sticking film and the adhesive layer are made of the same material and are water-based acrylic pressure-sensitive adhesive, silica gel pressure-sensitive adhesive or solvent-based acrylic pressure-sensitive adhesive.
In order to facilitate cutting, a dotted line is arranged at the joint between the dust adhering film and the adhesive layer.
Antistatic coating
The phenomenon that when the release film is torn by light peeling force, powder particles or dust are adsorbed on the surface of the protective film body due to static electricity, and then the non-fit property of the breathable protective film and the surface of a product is influenced, and the phenomenon of swelling occurs.
The antistatic coating not only contains an antistatic agent, but also contains carbonate, and is decomposed to generate bubbles when being dried and heated, so that the antistatic coating forms a porous antistatic coating. The principle of the air holes formed on the adhesive layer is consistent with that of the air holes formed on the adhesive layer.
