draagfilms

Draagfilms, also known as carrier films, are thin, flexible polymer films used as temporary substrates or carriers in the processing and handling of other materials. They provide mechanical support, dimensional stability, and controlled release of adhered layers during subsequent steps such as lamination, printing, coating, or transfer processes. After the functional layer is applied, the draagfilm is separated and removed, leaving the final product intact or with the intended pattern.

Common materials include polyethylene terephthalate (PET), polypropylene (PP), polyethylene (PE), polyimide (PI), polycarbonate (PC), and occasionally cellulose triacetate or nylon. Depending on the application, films may be glossy or matte, have specific surface energies, be clear for optical applications, or be chemically resistant to solvents and heat. Surface treatments, such as corona discharge or silane coatings, are used to tune adhesion between the draagfilm and its coating or product.

Applications: In labeling and packaging, draagfilms function as release or transfer carriers for adhesives, foils, and prints. In electronics and solar technologies, carrier films provide a substrate for thin-film deposition or pattern transfer, later removed to reveal the functional layer. In decorative transfers, decals, and protective laminates, draagfilms enable precise application and high-quality finishes.

Manufacturing and processing: Films are produced by extrusion or casting and may be laminated or coated with adhesives, inks, or oxide layers. They can be engineered with built-in release properties or used with release liners to facilitate removal.

Environmental notes: Recycling and disposal depend on the film material and its use. Separation from final products is typically required for recovery of both carrier and functional layers.
