Polymers are essential in modern food packaging thanks to their low cost, light weight, flexibility, and chemical stability. They provide a crucial barrier to protect food from moisture, oxygen, sunlight, and microorganisms that cause spoilage and health risks. Among them, PET (polyethylene terephthalate) is especially valued for its transparency, stability, and strong mechanical properties.
