Abstract

Packaging materials are used to create a modified atmospheric condition around the fruits and develop a low oxygen zone for shelf-life extension during storage. Among different packaging materials,LDPE (low density polyethylene), HDPE (high density polyethylene), Cling Film and Shrink Film are widely used as packaging materials. LDPE (low density polyethylene) is characterized by high permeability to carbon di-oxide and other gases, HDPE (high density polyethylene) has high tensile strength, Shrink Film packaging materials can reduce shrinkage and mechanical damage to fruits while Cling Film is plastic stretch film which protects the fruits from loss of moisture and severely restrict the ventilation.
