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.



Summary

Polymers are vital for food packaging due to their affordability, lightness, flexibility, and stability, acting as barriers against moisture, oxygen, light, and microorganisms that spoil food and pose health hazards. PET (polyethylene terephthalate) is a particularly important polymer appreciated for its transparency, stability, and strong mechanical properties, making it a preferred choice for preserving food quality and safety.
