COMPOSTABLE BIOPOLYMER COATINGS FOR IMPROVING FUNCTIONALITY OF MOLDED PULP FOOD PACKAGING

Abstract

Paper is most widely used in packaging application. But it has some properties create hindrance to its use in the packaging application. Its characteristics of printability, recyclability and biodegradability make more use in packaging industries. It is also useful as per environmental concern, it replace the plastic packaging materials with the degradable material. The work has main purpose is to improve the properties of the paper using some biopolymer which are either home or industrial compostable. Here, we are increasing the properties of water vapour barrier, grease barrier and heat seal strength of the paper material using coating of biopolymer on it. Here, we are testing three types of method to improve the above mentioned properties.
