EDL Packaging Engineers offers Proteca Pack Hibrid. It offers protection of sleeve wrappers with the flexibility of a stretch wrapper. According to the company, this system combines bundling and stretch wrapping technologies, applying a sleeve of poly foam, bubble wrap, LDPE or high abuse film to protect the top, bottom, leading and trailing faces and edges of a package. More film is then applied to help secure the package's integrity. The Hibrid system wraps random sized products and adjusts the tension of the stretch film to the shape and size of the product, states EDL.
