DIFFRENT TYPES OF FOOD
PACKAGING MATERIALS.
Presented by:- OM VACHHANI

INTRODUCTION
• Packaging material are chosen based on their physical, chemical,
and mechanical properties.
• These properties affect food safety, shelf life, and cost.
• These are based on things like how well they protect against outside
factors, their strength, whether they can be recycled, and how they
hold up against other things in the environment.

temperature.
• Protect food from damage
during transportation.
• Can be molded into various
shapes and size.
Limitation.
• PS is a brittle material.
(Meaning it can be prone to
cracking or breaking under
stress.)
• PS is not bio-degradable.
• Low heat resistance.
• Limited recycling facilities
available for PS.

 PP-polypropylene.
Properties.
• Polypropylene is a popular food packaging
material due to its safety, durability,
lightweight, nature, and resistance to
moisture, chemicals, and heat, making it
suitable for various food applications.
