DuPont Bynel® 4208 Anhydride-Modified LDPE Adhesive Resin

 

Subcategory: Polyethylene; Thermoplastic; LDPE

Key Words: Low Density Polyethylene; DuPont Packaging Polymers

Material Notes:
Bynel® Series 4200 resins are anhydride-modified, low-density polyethylene resins. They are available in pellet form for use in conventional extrusion and coextrusion equipment designed to process polyethylene (PE) resins.

Applications: Bynel® Series 4200 resins are specifically designed to provide high interlayer adhesion between EVOH, polyamide, PE, ethylene copolymers, and ionomers. Applications in which the use of these resins is advantageous include: barrier bag-in-box films; large pouches for hospital, restaurant, or institutional uses; rigid containers in which PE is the structural component. In addition, with their high adhesion to ionomers, these resins are advantageous in multilayer ionomer/barrier constructions designed to package oily products. Bynel® 4208, with its low melt index, is particularly useful where better bubble stability in the blown film process or less parison sag in coextrusion blow molding is desirable. Bynel® 4288 is specifically designed for high bonding performance with EVOH in high-speed coextrusion coating or laminating applications. It can also be used in cast film applications.

Physical properties of Bynel® Series 4200 resins are typical of low-density polyethylene resins with similar density and melt index values. The rheology characteristics of each grade are different, so one may be better suited than the others to a particular extrusion process.
