HIGH BARRIER FILM LAMINATE
Field of the Invention [0001] The present concept relates to laminate packaging materials and in particular relates to a high barrier film laminate that is used in the food industry.
Background of the Invention [0002] Currently high barrier food packaging materials consist of a paper that is laminated to a foil barrier. This construction is used for example in the packaging of coffee and other food - stuffs.
[0003] Unfortunately these packaging materials do not break down very easily in land fill sites and also contain heavy metals and other contaminates which are undesirable.
[0004] There is a need for a packaging material having high barrier properties that can be used in the food packaging industry, which is easily biodegradable and does not contaminate the landfills with undesirable heavy metals and/or other toxins.
[0005] The present structure a film of laminate construction for producing on a packaging machine a flexible container for containing food includes the following layers. A layer of natural Kraft paper for forming an outside layer of the container followed by a layer of adhesive. A layer of PE also known as polyethylene followed by a layer of tie adhesive for bonding two layers together. A layer of EVOH also known as ethylene vinyl alcohol and another layer of tie adhesive for bonding two layers together. A layer of PE sealant also known as polyethylene sealant for forming an inside layer of the container, wherein the layers preferably containing an organoleptic biodegradable additive to accelerate decomposition of the film laminate.
