Pre-coated films are typically classified based on substrate type, coating material, and application to facilitate standardized management in production and application. By substrate type, pre-coated films can be categorized into metal-based films, plastic-based films, and paper-based films, with metal-based films being the most widely used. Plastic-based films are primarily used for protection or packaging, while paper-based films are often used for short-term protection or decorative purposes. By coating material, they can be classified into polyester, polyurethane, fluorocarbon, and acrylic types, each imparting different weather resistance, corrosion resistance, flexibility, and surface aesthetics.
Pre-coated films can also be classified according to application field and functional requirements. For example, pre-coated films for construction require high weather resistance and UV resistance, films for transportation vehicles emphasize abrasion resistance and adhesion, while films for home appliances or decoration prioritize surface smoothness and gloss. This multi-dimensional classification of pre-coated films allows for refined management during production, testing, and application, ensuring that the film's performance and lifespan meet expected requirements in different scenarios.
