Multilayer TPE technology to improve packaging appearance and feel

The world's leading manufacturer of high-performance customized thermoplastic elastomers (TPEs), GLS Thermoplastic Elastomers division of PolyOne's Specialty Engineered Materials business announced earlier that it will team up with Kautex Plastics Technologies AG. Multi-layer technology developed, this technology will provide packaging designers with new options.

According to reports, HDPE is the material of choice for many packaging applications. However, achieving a good haptic effect requires an additional coating process. Combining the high performance and aesthetics of GLS Dynalloy thermoplastic elastomer alloys with Kautex's co-extrusion blown-blown ultra-thin film forming technology, customers can increase high-density poly through this breakthrough and low-cost new solution Ethylene (HDPE) containers and packaging properties.

This unique and innovative technology helps designers add the unique feel and beauty of TPE materials to HDPE containers and packages while achieving lower cost and environmental performance. G&G, a leading manufacturer of GLS and extrusion blow molding equipment, has jointly developed a process for co-extruding a translucent, custom Dynalloy ultra-thin outer layer onto recycled or original high-density polyethylene (HDPE) resin. technology.

Designers can use this breakthrough, high-precision, multi-layered process solution to add soft feel and non-slip surfaces to packaging materials for product differentiation. The new design offers design possibilities that include a non-slip “grip” strength adjustment that meets safety requirements, as well as an increased ergonomically soft feel to enhance aesthetics. In addition, this technology also offers the option of coloring the TPE coating or displaying a color high density polyethylene (HDPE) with a translucent TPE coating, and supporting the use of recycled resin in specific coatings to improve durability. More importantly, even the latest container designs can make TPE an affordable option.

Kauths multi-layer process technology allows up to 7 layers of material coating, making it possible to add oxygen barrier films or other special coatings. For example, the inner layer of the package design can use the original new high density polyethylene (HDPE) to meet food contact requirements, and the middle and outer layers can use recycled high density polyethylene (HDPE) and Dynalloy thermoplastic elastomer alloy, respectively. Each material layer is tightly bonded by co-extrusion prior to blow molding into bottles or other components.

Kautex can precisely control the thickness of the TPE coating, requiring only a few mils (usually 2-3% of the total thickness) to provide optimum performance. Dynalloy can be customized according to the user's specific requirements to provide different levels of grip or softness; in addition, it can also be colored in various shades.
