Shellac For Film Formation And Its Modification For Enhancement Of Properties

Ajay Dhawale


With the growing environmental concerns associated with synthetic polymers, the need for biopolymers has strongly emerged which can have applications ranging from packaging to electrical applications. Shellac, which is a naturally occurring product resin obtained from insects (female lac bug), is one such component which can be used for production of biopolymeric film. However, due to limitations on mechanical and barrier properties, modification of Shellac is necessary. Following is a reviewed study of modifications of Shellac to improve its film properties, heat resistance, water resistance, gloss and hardness.
