What Is The Use Environment And Bonding Requirements Of PE Protective Film?
Dec 08, 2021
Speaking of protective film, this should be familiar to us, because there are many products that are used, such as our mobile phones, which are also used, and the protective film is divided into many types, pe protection Film is one of them, so what is the use environment and bonding requirements of pe protective film?
The PE protective film starts from the production process during the manufacturing process. When the production is carried out, it mainly starts from the PET substrate. The PE protective film will effectively pass the PET substrate through the corona or primer, and then use it to coat it. The gluing of the cloth machine is then passed through the drying tunnel, winding and curing and slitting, and then the finished product is obtained.
In order to maintain the appearance of the PE protective film, there will be no migration of static materials. Its products are non-toxic, tasteless and environmentally friendly, so it has a good application effect. Therefore, this kind of maintenance film can be used on packaging materials, inserts and displays in order to get the desired effect.
The glue used in the production process of PE protective film, under normal circumstances, there are two types of glue: silicone glue and acrylic glue. The choice is mainly based on the bonding requirements, and it is up to it to decide. The high-transparent PET maintenance film is a kind of PET maintenance film. On the glue, there are two types of silicone system and OCA system. The difference between them is mainly in curing. The former is thermal curing, and the latter is For UV curing.
After the PE protective film has been used for a period of time, the center will perform well, but the two ends of the product will show the phenomenon of warping. The main reason for this phenomenon is that the maintenance film and the maintenance profile are stretched during the posting process. To a large extent, it shows unnecessary retraction in a high temperature environment.
In the process of production, PE protective film should be useful to pay attention to the impact of its environmental temperature difference on the use of its products, prevent unnecessary external stretching during the process of posting, and when the user completes the installation of the profile during the process of use In the future, when it is necessary to tear off the maintenance film from the appearance of the profile.
