EDI® Layer Multiplication Technology

EDI® Layer Multiplication Technology

US Patent 9,108,218
Developed for film and sheet processes, Layer Multiplication Technology (LMT) helps extend the shelf life of retort, hot fill, and flexible packaging while increasing thermoformability.

Overview


A layer multiplier is a special tool that can be engineered to multiply some or all of the layers within a coextrusion “sandwich”  provided by a feedblock. The resulting microlayer structure then passes into the manifold of an extrusion die, where it is transformed into film or sheet of target width and thickness profile.  

Trust Our Experience

We began working with layer multiplication technology in the early 2000s as part of a contract with the U.S. government. Since that time, we've used our knowledge of real-world applications to develop and hone the patented EDI® system that was first launched in 2009. 

Features at a Glance


Designed to Meet Your Needs
Coextrusion Feedblock Technology Compatible with both EDI® adjustable and fixed geometry feedblock designs
Quick Layer Adjustments The included inserts are easily changed, allowing layer multiplication levels to be altered quickly
Space Envelope Our streamlined design requires the smallest space envelope in the industry

Benefitting Your Process


Multiplied Layers

Maintain Film Thickness Requirements


When using an EDI® layer multiplier, the overall thickness of the film or sheet remains the same as that of a conventional coextrusion, regardless of how many microlayers are buried in the structure. 
Food Packaging

Improve Barrier Properties


When used in food packaging, the oxygen transmission rate (OTR) and total oxygen ingress are reduced over an extended period of time, resulting in longer shelf lives.
