Caps and Closures Plastic Resins
Growth in the beverage and food industry rapidly drives the demand for polyethylene, polypropylene, and resins for beverage caps and closures.
The trend in beverage packaging is to down-gauge with lightweight and standard short neck closures. The use of lightweight closures is spreading through the beverage industry which is aiming to use less polymer but still retain all the performance characteristics of standard caps and closures. The application typically requires a balance of toughness and stiffness, combined with easy processability, and excellent organoleptic properties, particularly for beverage applications which include, still water, pasteurized water and carbonated soft drinks (CSD).
