Blade Assemblies offer alternative to spinning knives.

Press Release Summary:

Custom-engineered for cutting and perforating operations in tamper-evident banders and shrink sleeve labelers, PDC blade assemblies are manufactured from tool steels for wearability, toughness, flatness, and edge profile uniformity. Blades operate dust-free; eliminate hairs typical of spinning knife systems while delivering precise cuts for months, even under continuous, high-speed conditions; and can be re-sharpened multiple times. Double-edged (reversible) versions are available.

New Cutting Technology Makes "Spinning Knives" Obsolete

  • Any Consumer Products Company or Contract Packer who runs shrink labeling or tamper-evident packaging and wants to substantially reduce machine downtime due to blade replacement

  • Companies who want low life cycle costs for cutting blades used in shrink
    sleeve packaging systems

    Norwalk, CT. PDC Corporation, a world leader in packaging equipment technology, has developed a cutting system that is a unique - and uniquely long-lived - alternative to the spinning knives that have, until recently been ubiquitous throughout the shrink sleeve packaging industry.

    PDC's patented blade assemblies are custom-engineered for precision cutting and perforating operations in tamper-evident banders and shrink sleeve labelers. They are manufactured from proven, extreme-service tool steels for maximum wearability and toughness. Manufacturing protocols developed by PDC insure precision flatness and exceptional edge profile uniformity. PDC blade assemblies operate dust-free, and eliminate "hairs" typical of spinning knife systems.

    PDC cutting blades are unique in their exceptionally long service life. The small, brittle, "spinning knives" that are commonly used by others dull quickly - often in days. In contrast, PDC blades deliver precise, clean cuts for months, even under continuous, high-speed conditions. PDC blades last months, not days.

    The robust design of the PDC blade assembly translates directly into less frequent machine downtime and substantially longer intervals between blade replacements. This directly results in increased uptime and higher productivity. Also unlike spinning knives, all PDC blades can be re-sharpened multiple times, and many of them are double-edged. These double-edged blades can be reversed, so that one set provides double the value and then both edges can be re-sharpened repeatedly.

    PDC blade assemblies deliver an extraordinary package appearance with minimal rejects. They are compatible with every major sleeving and labeling film, including PVC, PET, PETG, PLA, OPS, and stretch polyethylene sleeve labels. Very thin gauge material (30 to 50 micron, depending on speed and container configuration) can also be used with this PDC blade technology.

    PDC blade assemblies are manufactured in the US using one-of-a-kind, dedicated precision machining and grinding equipment. They are ideally suited for manufacturers and contract packers who want proven, cost-effective cutting blades for applying shrink sleeves with the highest reliability.

    Orders for PDC blades can generally be processed on a same-day basis, and in case of blade assembly refurbishing, loaner assemblies are always available.
