A broad line of high quality, custom engineered flexible and rigid thermoplastic films, produced through flat die extrusion for quality and consistency.
Manufacturers who produce ultra high volume consumer goods such as trash bags and sign banners often use the blown film or calendering production processes to create “good enough” film at rates of thousands of pounds per hour.
For higher quality film, Wiman uses the flat die extrusion process. Flat die extrusion enables tight tolerances, outstanding lot-to-lot consistency in surface quality and appearance, and pinhole-free film even down to the thinnest gauges. In fact, many customers find that, working with us, they can reduce costs by reducing the film thickness specification for their application, since Wiman can produce the thinner version with no pinholes. Flat die extrusion also provides the flexibility to impart different finishes on each side of the film.
Wiman has extensive expertise with polymers including, but not limited to:
- Rigid and Flexible PVC
- Polyolefins including Polyethylene, Polypropylene and blends
- Ethylene Vinyl Acetate (EVA)
- Thermoplastic Polyurethane (TPU)
- Acrylic (PMMA)
- PLA biopolymer
- Polycarbonate (PC)
- and more
Many of these films can be custom engineered with a host of engineered custom film properties.
