Flexible PET or LDPE films have been the most common substrates used in the printing and packaging industry because of its balance properties in relation to other thermoplastic polymers. However, the global sustainability calls for more environmentally, biodegradable and biocompatible materials.
This paper presents results from the experimental programme of formulating a hemicellulose based printable films. The biodegradable glucomannan films were formed with nanofibrilated cellulose, which reinforces the mechanical strength of the film and impart the film with good heretic integrity. The film shows a good potential to be a alternative or substitute of the PET film in printing and packaging industry.
