The part this solves
You have a trim component that has to hold its shape, take a fabric or vinyl finish, survive humidity in the cabin and worse in the plant, and hit a piece price an injection molded part cannot reach. Or you have a molded panel already in production and a cost or recycled content target that is forcing a substrate conversation.
Valdor substrates are laminated paperboard engineered for that job. Stiffness where the part needs to carry a load. A polyethylene moisture barrier, concealed below the surface or exposed on it, depending on whether the barrier has to be invisible in the finished assembly. A surface prepared for the adhesive or laminate you are actually using, corona treated for bond where that matters. Available with a black surface where the design requires the substrate to read as plastic. Made primarily from recycled fiber and fully recyclable at end of life, which is usually the second question after price.
Typical applications
- Door panels and door panel inserts
- Package trays and rear shelves
- Sun visor cores
- Load floors and trunk trim
- Map pockets and thin-section stiffeners
- Seating components and cover-up panels

Why the substrate comes from one plant
Extrusion coating, laminating, and die-cutting are all in this building, and PPAP runs in house. That matters more than it sounds. The coating that creates your moisture barrier, the lamination that builds your caliper, and the die-cut that produces your part geometry are all controlled by the same process engineers against the same print. When a dimensional or bond issue comes up, it gets resolved in one place instead of triangulated across three suppliers, and the submission documenting it comes from the same people who ran the part.
Polyethylene extrusion coating in house is the part worth underlining. Most laminators buy coated board in from someone else. When the barrier is applied on the same floor that builds your caliper and cuts your part, the coat weight becomes a variable you can tune to the part rather than a constraint you have to design around.
Quality and submissions
Fibre Converters is ISO 9001:2015 certified. The certificate is available on our Key Documents page.
PPAP submissions are prepared in house, so dimensional layouts, capability studies, and the submission package come from the same team that runs the part rather than from an outside lab on someone else’s schedule. Tell us the submission level you need with the RFQ and we will scope it into the quote up front.
Where it started
In 1953 Fibre Converters developed a non-staining, flame-resistant alternative to the asphalt-saturated board the industry was using for interior trim. When polyethylene arrived it became possible to put a clean moisture barrier just below the surface instead of on it. The Valdor line came out of that work and became the standard for interior trim substrates. Seventy years later it is still running on the same floor.

If you are converting an existing plastic part and do not yet have a board spec, send the plastic part number and the performance requirement instead. Our specialists will work the substrate backward from there, which is a cheaper conversation before tooling than after.
