PECTIN/CMC COMPOSITE FILM FOR FOOD PACKAGING MATERIAL Authors: Ahuja S , PATEL AS AND SINOJIA A
ABSTRACT
The current study examines pectin-based films that have been treated with carboxymethyl cellulose for
use in food packaging. The films are made using the solventcasting method, with varying levels of
carboxymethyl cellulose and crosslinker (Ca2 ions), and glycerol as a plasticizer. The produced films'
FT-IR spectra suggest that whereas OH groups are mostly involved in self-associated hydrogen bonding
of neat polymers, carboxyl groups from pectin are primarily involved in interactions with CMC.
Additionally, compared to pure pectin films, the addition of carboxymethyl cellulose enhanced the
mechanical capabilities, and TGA study revealed satisfactory thermal stability with relation to their
prospective use as packaging material.
