ABSTRACT:
A film-forming composition and a polymeric film or coating comprising hemicellulose, having a molecular weight of less than 50 000 g/mol, and at least one component selected from the group consisting of plasticizers, cellulose and a synthetic oligomer or polymer is disclosed. The use of said film or coating as an oxygen barrier is also disclosed. Further, a method for the manufacture of said polymeric film or coating is disclosed, as well as a method for improving the film-forming properties of hemicellulose having a molecular weight of less than 50 000 g/mol.

“An industry rule-of-thumb is that a material is considered a “high oxygen barrier” if its OTR is less than 1 cc/100 in2/24hr (15.5 cc/m2/24 hr).” http://www.polyprint.com/faq—otr.htm.
“Certain polymers are particularly useful in restricting entry of oxygen into packages. Such polymers, because they are highly impermeable to oxygen, are called high barrier polymers. They typically have an oxygen transmission rate (OTR) at 20° C of less than 15 cc/m2-day atm.” http://www.intracen.org/Tdc/Export%20packaging/EPN/English/epn38e.pdf.
