Derived from proprietary nanocomposite technology, Eastman’s Imperm resins are a new class of ultra high-barrier, nylon-based polymers for use in multilayer containers. Initial markets include multilayer PET bottle applications such as beer, juice and small carbonated soft drink containers.

Barrier performance of nanocomposite resins is said to be three to six times that of typical nylon barrier layers. This enables significant extension of the shelf life for products packaged in bottles incorporating Imperm resins.

Eastman will offer two Imperm nanocomposite formulas with different barrier levels, expected in June. The polymers are intended for use only as the internal layer in multilayer structures. Imperm resins can be processed on existing multilayer bottle equipment with minor adjustments.

Improved barrier performance allows the processor to use less Imperm resin than currently available polyamide-based barrier materials, for a net savings with improved performance, according to Eastman.

“We are continuing development work in other areas, such as light protection, to provide a total barrier package for the beer market,” says Greg O. Nelson, vice-president of polymers technology.
