A Case Study on Physical Properties Blends Analysis of Non-Degradable Films with Gray Back Boards

Abstract

In the printing and packaging industries blends of non-degradable plastic film and degradable paperboards is very common substrate. The gray back board is recycled pulp paperboard. The gray back boards are one side dull or gray color in physical appearances so it is called gray back paperboard. The gray back paperboards have not good strength and visual appeal as compare to other paperboards. But the printing and packaging industries are mostly using the gray back paperboards because the gray back paperboards are the cheapest material for package preservation, containment and transportation. The blends of gray back paper boards with plastic film gives good combination for packaging industries. This particular research work deals with study of gray back paperboards and plastic film blends
