Preparation and Characterization of Poly(ether-block-amide)/Polyethylene glycol Composite
Films for Packaging Application

The microwave markets are expected to witness remarkable growth fueled by consumer demands due to the need for the
ease of preparation and portability to consume on the go. The critical problems of microwave cooking are expansion of
internal pressure, explosion of package, and migration of chemical compound from the package into the food product during
cooking. This issue can be solved by improving the packaging materials and design such as a weak heat seal, shrink-film-
covered vent valves, and laser scored or perforated film. However, multiple processes are required to produce such packages,
which lead to relatively high production cost. In this study, it is proposed to develop polymer/phase change materials (PCM)
films with temperature responsive gas permeability as packaging materials as it have the characteristic of self ventilation and
applicable to use in microwave oven by preventing the damages and explosion of packaging during the cooking process.
A series of poly(ether-block-amide)/polyethylene glycol (PEBAX/PEG) composite films are prepared by solution casting
technique. The permeation properties, morphologies, thermal properties, and water sorption are interpreted as a function
of PEG with different molecular weights. The phase change and gas permeation property of composite films are significantly
dependent on the molecular weight of PEGs. Incorporation of low molecular weight PEGs (PEG 950-1050 and PEG 3350) into
PEBAX matrix showed a lower oxygen transmission rate (OTR) than pure PEBAX films in the measured temperature ranged
from 10 °C to a relatively low melting temperatures of each PEGs, which is due to good interaction between PEBAX and PEGs,
and an increase in crystallinity of the composite film by introducing PEGs. As the measurement temperature is increased
from the melting temperatures of each PEGs to 80°C, the OTR of composite films dramatically increased. The composite films
exhibited permeation jumps that occur at the melting point of crystallized phase depending on the molecular weight of PEGs.
The composite film incorporated with high molecular weight PEG exhibited highest permeation jump.
