Gravure printing is a high-quality printing process that uses a metal plate cylinder with recessed cells to transfer ink onto plastic film or other substrates. The ink is transferred from the cells to the material, creating the desired image or pattern.In the case of laminated material films, gravure printing is commonly used for packaging and labeling purposes. The process involves printing the desired design or information onto a thin plastic film,often call as outer film, or face film, such as BOPP, PET and PA, which is then laminated to create a layered structure.The film used in gravure printing for Laminerte materialer er vanligvis laget av et sammensatt materiale, for eksempel en kombinasjon av plast- og aluminiumsfolie. The combination can be PET+Aluminum foil+PE, 3 Layers or PET+PE, 2 layers, This composite laminated film provides durability, offers barrier properties to prevent moisture or air penetration, and enhances the overall look and feel of the packaging. Under utskriftsprosessen blir blekket overført fra graverte sylindere på filmoverflaten. De graverte cellene holder blekket, og et legeblad fjerner overflødig blekk fra ikke-bilderområdene, og etterlater bare blekket i de innfelte cellene. Filmen passerer over sylindrene og kommer i kontakt med blekkcellene, som overfører blekket til filmen. Denne prosessen gjentas for hver farge. For eksempel, når det er 10 farger som kreves for designen, vil det være 10 sylindere som trengs. Filmen vil løpe over alle disse 10 sylindrene. Once the printing is complete, the printed film is then laminated with other layers (such as adhesive, other films, or paperboard) to create a multi-layered structure. The printing face will be laminated with other film, which means the printed area is kept in the middle, between 2 films, like the meat and vegetable in a sandwich. Den vil ikke kontakte maten fra innsiden, og den vil ikke bli riper bort utenfra. The laminated films can be used for various applications, including food packaging, pharmaceutical packaging, daily-used products, any flexible packaging solutions.The combination of gravure printing and laminated materials film offers excellent print quality, durability, and enhanced product presentation, making it Et populært valg i emballasjebransjen.
Ytre film for utskriftsformål, indre film for varmeforseglingsformål,
Midtfilm for barriereforbedrende, lyssikker.
