Causes of PE protective film degumming?
- Jul 10, 2018 -

Wuxi Shengfa protection film Co., Ltd. is a professional company specializing in the production and sale of packaging materials. The main products are PE protection film, PE black and white film, PE blue film, black and white protection film, PE transparent film, PE color printing, PE car carpet film and so on, and are widely used in all kinds of aluminum and plastic plates, aluminum plates, stainless steel plates, and so on. Color steel plate, galvanized sheet, glass, stone, carpet, floor, plastic steel profiles, new decorative materials, plastic products and high-grade furniture and other industries. With regard to the problem of degumming of protective films, we will briefly introduce what problems will cause degumming.

1. users are most reflected in the degumming problem of protective film products. This problem is most reflected on the profile protection film. When the user tore the protective film from the surface of the profile after the installation of the section, the adhesive of the protective film does not follow the protective film, but it remains on the profile product. This is the user. The most reluctant to see, because it is very troublesome, need a special person to scrape the glue off the profile, especially the time and time, there are many possibilities. The biggest possibility is to protect the membrane products from the pressure glue that does not conform to the rules, that is, it is too sticky, resulting in the external tension of the PE protective film product when it is stripped. It is larger than the internal stress and remains on the profile. If the user appears this problem, can use a clean cloth dipped in a little alcohol, the residue of the sensitive adhesive repeated trial, until the sensitive adhesive is clean, but it is necessary to pay attention to the erasing must not be too hard, or may affect the profile product's finish.

The 2. protective film has a good performance in the middle after a period of use, but the main reason for this phenomenon is that the protective film has a greater degree of tension in the process of sticking with the protected sections. After the post is good, there is an unnecessary retraction of the image in the high temperature environment. This problem appears mostly in the South customers.  On the product, the PE protective film should pay attention to the effect of the environmental temperature difference on the use of the product in the production process, and avoid unnecessary surface stretching during the bonding process.

The 3.PE protection film and the protected product are not firmly attached to the product in the process of transportation and use. The reason for this problem is quite the opposite. The biggest possibility is to protect the viscosity of the sensitive adhesive used in production, and one possibility is when the user is doing the mold.  There is not enough pressure in the mold press, or the surface of the section is not clean, dust or paint, which affects the paste effect of the adhesive. If this problem appears, it is necessary to counter the reason, change the sensitive adhesive to increase the pressure of the sticker, or pay attention to the effective cleaning of the surface of the profile when the film is sticker, so as to avoid the appearance of such problems.

4. the protective film is difficult to peel off. When the product is stripped, the protective film can not be peeled off effectively. There are two possibilities. One is that the sensitive adhesive used for protective film products is not a special sensitive adhesive for protective film. If so, the protective film is very good when it is stickup, but it will be stripped when it is stripped. It is also a very difficult problem. It is also the most common problem of the protection film produced by the producers of illegal protective film products. There is also a possibility that the protection of the material used by the membrane is too soft to withstand the pulling force of the peel. It is a very headache problem for the household.

Although the 5.PE protective film product can be effectively stripped but there is a protective film expression on the surface of the profile, this problem is often found on some low-grade protective film products because the protective film is combined with the protected profile, and occurs in a suitable environment, such as sunlight water, and a kind of chemical cooperation. Use.
