Creating plastic film through biax dies with EDI BOPE & BOPP Film Dies

With the EDI BOPE & BOPP Film Dies users are able to be customize biax dies to meet the needs of each individual processors’ needs. The option to accommodate needs for versatility a range of distribution block systems are available. An often recurring problem for processors has been ensuring consistent durability and strength to their film, while making sure the visual requirements are met. To make sure of this proportional extrusion across its width is vital. That’s what the focus was when creating the EDI BOPE & BOPP Film Dies.

The EDI die system creates a precise structure from layer to layer, which facilitates the films withstanding integrity during the stretching process. This helps create a final product with large capabilities of withstanding chemical and environmental factors. 

Eliminate Weak Points in Film

It’s no secret: inconsistent layer structures create weak points when the film is stretched. In an EDI multi-manifold die system, every material is distributed in its own customized die flow channel prior to combination with the other layers. The layers then converge at full width, and shortly before exiting the EDI die system, reducing the chance of structural changes.

Save Material Costs

Biax film dies are designed for partial coverage, or a “naked edge,” allowing processors to minimize the material at the edges of the film, where the tenter clips are used during the stretching process. This means less trim, thereby reducing costly material waste.
