Overview

Processors have long tried to solve the problem of ensuring their film is produced with consistent strength and durability, while also meeting the visual requirement dictated by the end product's use. To do this, the structural elements in the film must be proportionally extruded across its width.

Delivering Uniform Film Structures

The uniform and precise layer-to-layer structure created by an EDI® die system means the film's integrity remains intact during stretching, creating an end product with exceptional protective qualities against chemical and environmental factors.

Benefitting Your Process

Ensure Consistent Film Properties Across the Width

It's no secret: inconsistent layer structures create weak points when the film is stretched. In an EDI® multi-manifold die system, each 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 die, reducing the chance of structural changes.

Increase Production Efficiency

EDI® BOPET film dies are designed for partial coverage, or a "naked edge," allowing processors to keep skin layer material out of the edges of the film, where the tenter frame clips are used during the stretching process. This means better release from the clips which facilitates higher processing speeds.
