    Welcome to the World of ENDURA™
    D&K Group’s new Patent Pending ENDURA OVERLAMS™ offer a durable thermal laminating solution that is completely waterproof and impossible to delaminate. These tamper-resistant polyester (PET) overlams are stronger than other thermal products on the market, making them ideal for demanding applications including cards, menus, durable labels, and more.

    ENDURA™ laminating films are completely water-resistant and are suitable for moist or wet environments where other thermal films fail. Compared to pressure sensitive laminating films, ENDURA™ products offer equivalent performance at a fraction of the price. Plus, the quality far exceeds that of low-grade, self wound pressure sensitive products.

    ENDURA OVERLAMS™ are offered in a variety of film thicknesses and finishes. Adhesives are also available for all types of prints including difficult digital output. For projects requiring up to five year outdoor durability, D&K offers versions containing UV inhibitors to help prevent fading and color shift caused by sunlight.

    ENDURA OVERLAMS™ are made in the USA to high quality standards. These products are also FDA compliant, making them suitable for applications involving direct or indirect food contact.

    Durable, Waterproof Protection

    ENDURA waterproof & tamper-resistant Polyester Overlams provide a tough, protective surface with a beautiful finish for all types of projects. Polyester is an outstanding choice for demanding applications that require high performance. Additionally, polyester offers excellent durable properties including high tensile strength, thermal stability, and tear-resistance.

    Films are available in a variety of widths and thicknesses to meet your project requirements. ENDURA™ Polyester Overlams are offered in configurations up to 10 mils thick for heavy-duty applications such as cards and hang tags. These PET Overlams stand up to frequent handling and harsh conditions where other products fall short.

    Lay-Flat Polyester

    D&K Group offers ENDURA™ Polyester Overlams in “mapped and matched” roll pairs for applications that must remain perfectly flat. D&K Group’s special map and match process pairs up film rolls that eliminate curling or “potato chipping” when used together. Lay-flat Endura Polyester Overlams are ideal for two sided products such as cards that require completely flat characteristics.

    UV Polyester

    ENDURA OVERLAMS™ are available with added UV protection for outdoor applications. ENDURA™ UV Overlams protect against graphic fading and color shift caused by sunlight. UV protection in the base film doubles the outdoor lifespan of unprotected inks and substrates. These UV products offer up to five year outdoor durability.


    As a USA manufacturer specializing in custom adhesive coating services along with custom laminating film solutions, D&K Group constructs specialty ENDURA OVERLAMS™ designed to meet unique project requirements.

    ENDURA OVERLAM™ Laboratory Validation

    5 year card validation

    ENDURA OVERLAMS™ are third-party tested and validated for performance in demanding applications. These products have been evaluated using ISO/IEC standards to test physical properties including peel strength, accelerated aging, and more. Cards manufactured using ENDURA OVERLAMS™ were evaluated under the following standards:

    Test Standard ISO/IEC 24789-1: Card Testing for Usage & Aging, and Card Testing for Film Delamination:
    – ISO/IEC 7810 – Card Testing for Peel: (PASSED)
    – ISO/IEC 24789-1 – Card Testing for Flex: (PASSED)
    – Accelerated Humidity Cycle Aging: (PASSED)

    According to the laboratory results and analysis, “ENDURA OVERLAM™ card samples tested for film delaminating usage and aging performed better than Standard (non-ENDURA OVERLAM) card samples. It is my interpretation of the data that ENDURA OVERLAM™ cards have a more durable film based upon the peel testing results. It is my opinion that ENDURA OVERLAM™ cards have a strong core peel strength after stress and aging and are not expected to delaminate under normal use within a 5 year service life.”
