The oxygen barrier coating protects packaged food from oxygen and thus enables recycling-friendly mono-material packaging.
HYDRO-LAC GA Oxygen barrier coating
The oxygen barrier coating protects food stored in flexible packaging from oxygen and thus enables mono-material solutions for products such as muesli or nuts. The varnish is favourably being used as a layer between two foils of a laminate, e.g. polypropylene or polyethylene.
Flexible food packaging often consists of combinations of different films and is therefore difficult to recycle. hubergroup’s oxygen barrier varnish protects packaged food from oxygen and thus enables recycling-friendly mono-material packaging.
Under industrial conditions, two polypropylene films with an oxygen barrier varnish in between achieve an OTR (oxygen transmission rate) of less than 10 cubic centimetres of oxygen per square metre and day.
