Hvad er Gravure -udskrivning og lamineret materialefilm?

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 Laminerede materialer er typisk lavet af et sammensat materiale, såsom en kombination af 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 gravure -udskrivningsprocessen overføres blækket fra de indgraverede cylindre på filmoverfladen. De indgraverede celler holder blækket, og et lægeblad fjerner det overskydende blæk fra områderne ikke-billedområder, hvilket kun efterlader blækket i de forsænkede celler. Filmen passerer over cylindrene og kommer i kontakt med de blækkede celler, der overfører blækket til filmen. Denne proces gentages for hver farve. For eksempel, når der er 10 farver, der kræves til designet, er der 10 cylindre, der er nødvendige. Filmen kører over alle disse 10 cylindre. 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. Det vil ikke kontakte maden indefra, og den vil ikke blive ridset væk udefra. 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 emballagebranchen.
