High temperature resistance and application of PE single and double-sided copper plated aluminum plated protective film

PE single and double-sided copper platingThe high temperature resistance of aluminum plated protective film, PE single and double-sided copper plated aluminum plated protective film is widely used in food packaging and protective film, and is also common in daily life. In traditional packaging, the food and medical industries generally use the most quantity, and the packaging used in the past has caused significant environmental pollution. Life is basically packaged and stored using PE protective film for food. PE protective film is often in two temperature states, one is low temperature and the other is high temperature. We won't talk about low temperature. The PE film technical engineer below will tell you what the highest high temperature resistance of PE protective film is.

Polyethylene protective film is the simplest polymer organic compound in the world and also the most widely used polymer material in the world. PE protective film is based on special polyethylene (PE) plastic film and can be divided into high-density polyethylene protective film, medium density polyethylene protective film, and low-density polyethylene protective film according to different densities.

PE can be divided into low-density polyethylene (LDPE) and high-density polyethylene (HDPE). The continuous working temperature of polyethylene is 60 ℃, and the continuous working temperature of high-density polyethylene is 80 ℃. High temperature resistance can reach 100 ℃. Heating the PE protective film will not release toxins.

Characteristics of PE single and double-sided copper plated aluminum plated protective film:

The adhesion and thickness of the protective film should be selected according to the product and environment used by the customer.

2. Stable adhesive force, suitable for products in various high-temperature environments, providing a good protection solution for high-temperature formed sheets such as diffusion boards, whitening boards, PC/PET/PVC copper plated aluminum coated film boards, etc.

3. The heat-resistant protective film effectively protects without producing water streaks, white mist, ghosting, and other phenomena. It is easy to peel off and is widely used in products such as polishing, electroplating, and circuit boards.

Application of PE single and double-sided copper plated aluminum plated protective film:

To prevent surface migration of electrostatic materials,PE copper plated protective filmNon toxic, odorless, environmentally friendly, and has good effects. Therefore, this protective film can be used in packaging materials, inserts, and displays to achieve the desired effect.

In the production process of PE copper plated protective film, adhesive is generally used, which includes silicone and acrylic adhesives. The choice mainly depends on the bonding requirements, which are determined by them. High transparency PET protective film is a type of PET protective film that has the influence of silicone system and OCA system on adhesive. The main difference between the two is curing, with the former being thermosetting and the latter being fixed on UV.

After using PE protective film for a period of time, it performs well in the middle, but there is a phenomenon of rising at both ends of the product. The main reason is that the protective film and protective layer stretch greatly during the bonding process, and there is unnecessary shrinkage in high temperature environments.

During the production process, the PE aluminum plating protective film should effectively pay attention to the impact of environmental temperature differences on product use, avoiding unnecessary surface tension during the bonding process. When users install and construct profiles, the protective film needs to be torn off from the surface of the profile.
