Abstract
Official abstract text for this publication.
The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties.
First claim
Opening claim text (preview).
What is claimed is: 1. A blow molded product comprising 2-10,000 micro or nano polymer layers, at least one of the polymer layers including lamellar crystals aligned along the axis of extrusion. 2. The blow molded product according to claim 1 , wherein the blow molded product is a packaging. 3. The blow molded product according to claim 1 , wherein the blow molded product is a medical device. 4. The blow molded product according to claim 1 , wherein the at least one of the polymer layers including lamellar crystals are aligned along the axis of extrusion to enhance barrier properties. 5. The blow molded product according to claim 4 , wherein the blow molded product is packaging. 6. The blow molded product according to claim 4 , wherein the blow molded product is a medical device.
