Product-by-product comparison of Bynel® adhesive resin grades, showing melt flow, melt point and other processing characteristics as well as adhesion performance when coextruded with other resins such as polyethylene, polyester, polyamide (nylon), ionomer, polystyrene, polypropylene and EVOH.
New Bynel® adhesive resin development is an ongoing process that involves scientific investigation of adhesion and processing performance in specific situations based on customer needs and feedback. During new grade development, and in response to customer feedback, grade names will often progress from initial (experimental) status to commercial status.
Advanced blow molding techniques, enhanced polymer formulations and creative conceptual solutions now allow more complex bottles and containers to be blow molded using specialty polymers. These trends have led many companies to explore the use of specialty resins in order to strengthen their offering, defend their competitive position, and also meet stringent application requirements.
We can help you create cost-effective solutions, increase your efficiencies and improve your sustainable position.
Many typical extrudates in packaging do not bond well to the common substrates and require the use of an extrusion lamination adhesive to improve adhesion. DuPont Packaging & Industrial Polymers has the widest offering for primed and unprimed substrates in the industry.
