Custom Poly Cases & Storage Trunks

Poly cases at Trifibre are tough, durable, and splash-proof, made from HDPE and can be customized to fit your needs. One of the main advantages of getting a Trifibre polypropylene box is that it does not require tooling costs, making it a cost-effective casing solution. Our poly cases are constructed with a welded steel metal frame around the top to provide a more rigid and robust structure, making them an ideal storage trunk option. Additionally, you can customize your poly case with various handles, shoulder straps, lid retainers, foam linings, custom-made foam inserts, and wheels. A standard poly case starts out as a flat extruded sheet of HDPE between 1.3 and 2.0mm in thickness. The sheet is then scored and bent around a welded steel metal frame to give it a more rigid structure. All designs can be tailor-made to meet your specific storage trunk needs. While our poly cases may not be as hard wearing as our flight cases, they are ideally suited for light and medium-duty applications and offer a cost-saving alternative to our custom-built flight cases and a more reusable, longer-lasting alternative to traditional packaging
