At present, there's no such internatinal standards. Each company has its own standards. It's for reference that the adhesion of protective film is usually classified into four degrees which are slight, low, meidium, and high. Generally, 0.02-0.1N refers to slight degree; 0.1-1N,low degree; 1-2N, medium and 2-6N, high. But this is not always the same. It depends on the requirements of themanufacturers.

The ways to remove the protective film on stainless steel door: 1. If the film is not too big, you can apply some lacquer thinner to it and then scrub it with cleaning ball. 2. Detergent used in textile industry will work (Bottled such detergent is called al). I've tried it. It really works well. 3. Use sulfuric acid. But you should mix it with water before use, otherwise the door will corrode. Immerge the door into the mixed sulfuric acid for a period of time and scrub it with cleaning ball. 4. Firstly, use electric hair drier to heat the film. And them slowly tear it off or scratch it off with wooden shovel. The glue marks can be cleaned by solvent oil. If you don't have hair drier, boiling water is also okay! The best way is to heat the film at first and then clean it with talcum powder. It can stay glossy and new.

PP material: material used in plastic bags that we often use. The chemical name of PP is polypropylene. PVC material: PVC material is more thick but its light transmittance is not good. PET material: the chemical name of the film made from this kind of material is polyester thin film. AR material: AR is a kind of synthetic material, generally composed of three layers--the silica gel as the adsorptive layer, PET as the middle layer and outer layer as the special processed layer. Special processings usually can be divided into two kinds-- AG processing and HC processing. AG processing is anti-glare processing, adopted when making matte protective film. HC processing is hard coating processing, used on protective film of high light transmittance.

You can wipe it off using paper with some alcohol (Industrial alcohol is better while medical alcohol is also acceptable.). Then scratch it. The film will be cleaned up. Besides, you can use nail polish remover. The way of use is the same as that of alcohol and acetone. The effect is quite good. The quality of the polish remover can be either good or ordinary as long as it can remove the nail polish.

I suppose you're talking about protective plate. PET film is a kind of film used in packaging. It's used to cover the battery core. The battery is steel shelled when it's produced. The outer layer of PVC needs to be coated. Cover the battery with the film at first. Then heat the film with hair drier to soften it. Otherwise it won't be insulative. And it may cause short circuit. If you have any question, you can directly ask me.
