Q:How to define the adhesion degrees of protective film?
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.
Q:What's the different between stretch film and protective film?
Stretch film is used for packaging. But protective film can be used in many ways. For example, protective films like static film and film with glue are used in industry to protect the surface of the products from pollution, damage, dust and keep them clean during production and transpotation to increase the market competitiveness of the products.
Q:What is PVC protective film?
1. It has the property of highlight and high reflective which is commonly called the mirror effect. 2. It has resistance to acids and alkali as well as corrosion. And no residual glue remains when removing the film. Use: It can be widely used on the protection of stainless steel sheets as well as aluminium products and industrial products during processing. The scotch tapes hanging on the doors of many restaurants are also made from PVC materials which are generally called PVC films. We have many nice films of this type . And we assure you they are all of good quality and reasonable price.
Q:What to do if the adhesion of the PE protective film is too high?
PE protective film in industry is made of acrylic acid PSA coating (Silica gel is mainly used in PET protective film). The adhesion of protective film is determined by the proportion of original gum and the amount of glue. In the process of application,though, PSA protective film has problem of high adhesion because of the high stickiness of itself.It's directly related to covering and the storage of pressure and temperature. As is known to all, PSA glue is only sensitive to stress. You can adjust the pressure stored when or after the covering. If the protective film itself has high adhesion, you can try to use it when it cool down (Using at temperature below 20℃, you will clearly feel the adhesion comparatively decreased).
Q:Is it okay not to tear off the protective film on the mirror stainless steel during laser cutting? How about the effect?
If it's ordinary film, it can be torn off. And you need to coat the stainless steel with specific laser film. At present, most stainless steels are covered with ordinary films. But if you need to do the laser cutting processing, you'd better require the manufacturer to use specific laser film when you buy the plates. Generally, laser film is thicker. And it's not easy to wear out. Apart from that, it won't be blown away during cutting. It protect the stainless steel all the way.
Q:What to do when the protective film on plastic steel window is useless and difficult to remove?
You can buy a bottle of xylene solvent from building materials stores to clean it out. Be careful that the solvent is volatile and toxic. Notice to ventilate when using it.
Q:Will the hardware oil layer be taken off with the protective film while tearing the film down?
It's unlikely to happen when coating the film.
Q:What are the differences between PE protective film and PE release film?
PE protective film is used for the primary protection of electronic products when they leave the factory while PE release film is used as disposable consumable to protect the raw materials when wastes is discharged during processing.
Q:How to remove the protective film on stainless steel door after using for a long time?
You can give vinegar a try if you really can't find other ways. Mix the vinegar with some hot water and scrub the door using warm towel. Apart from that, using electric hair drier is also a goog idea. But you should blow the film and rub it off at the same time.
Q:What kinds of materials is the protective film made from?
PE, PET, CPP, OPP, EVA and PVC.
