KB Packaging supplies the trusted Pro-loc range of Polygrip self seal grip bags, designed for secure, convenient, and reusable storage of documents, larger components, and industrial parts.

Each bag features a strong interlocking ridge seal that clicks shut and opens easily, allowing for repeated use without loss of performance.
