Blue plastic packaging film, also known as super blue film, is a kind of microcrystalline point protective film that uses the solar spectrum to selectively absorb the coating. It is deposited on the relevant metal surface to collect solar energy. It is a new generation of solar energy utilization. technology. It has a very high absorption rate of solar radiant energy, and its own emissivity is very low, which can effectively improve solar energy conversion efficiency.

Our plastic packaging film is the most widely used in the packaging field. Plastic packaging film can be used for food packaging, electrical product packaging, daily necessities packaging, clothing packaging and so on. They have one thing in common, that is, color printing is required for plastic packaging films, which is also a kind of printing film, and as food packaging, it is necessary to perform processes such as multi-layer composite or vacuum aluminum plating. Therefore, this requires our plastic film to have high surface free energy and high wet tension to facilitate the firm adhesion of printing inks, adhesives or aluminized layers to the plastic film; in the production of plastic packaging film, reel and high-speed In the packaging process, the surface of the packaging film is required to have a certain friction performance to prevent the film from sticking or slipping; when used in the packaging of electrical appliances and electronic products, the packaging film is required to have certain antistatic properties and so on.
