Heat Seal Strong CPP Aluminium Plasting Film for Instant noodles, potato chips, biscuits Bag

Strong CPP aluminized film is a packaging material with specific properties and uses. The following is a detailed introduction about it:
Material composition
Base layer: Cast polypropylene (CPP) film is used as the base material. CPP film is a polypropylene film produced by the casting process, which has good transparency, glossiness, flexibility and heat sealing performance.
Aluminized layer: A very thin aluminum layer is plated on the surface of the CPP film through the vacuum aluminizing process. The aluminized layer generally uses high-purity aluminum wire. Under a high vacuum environment, the aluminum wire is evaporated and deposited on the surface of the CPP film by heating to form a uniform aluminum film. The thickness of this aluminum film is usually between tens and hundreds of nanometers, which gives the film excellent barrier properties and optical properties.
Features
High barrier properties: The presence of the aluminized layer greatly improves the film's barrier ability to gases and liquids such as oxygen and water vapor. It can effectively prevent the items in the package from getting damp and oxidized, and extend the shelf life of the product.
Good optical properties: With excellent gloss and reflectivity, the packaging has a good visual effect, which can attract consumers' attention and enhance the appearance quality and grade of the product.
High strength and flexibility: Strong CPP aluminized film not only has the rigidity of the aluminum layer, but also retains the flexibility and high strength of the CPP film, making it not easy to break during the packaging process, and can adapt to various packaging forms and processing techniques.
Good heat sealing performance: It can be heat-sealed at a lower temperature, with high heat sealing strength, which can ensure the sealing of the packaging and prevent leakage of contents.
Environmental performance: CPP material can be recycled, meets environmental protection requirements, and reduces the pressure on the environment to a certain extent.
