Many types of plastic food packaging, like plastic wrap packaging and plastic bags, are typically made out of high-density polyethylene pellets.
High heat and pressure liquify these pellets, so they can be blown into a long tube shape. As the tube-shaped plastic starts to cool, giant rollers flatten it into a thin sheet.
To make plastic bags and similar items, the plastic is then cut and put onto a giant roll of plastic, where it will be printed with alcohol-based ink. It is then formed into its desired shape and heat-sealed.
Plastic Packaging in Everyday Life
Plastic packaging is essential in a variety of industries to make a wide range of products.
Without these different plastic packaging technologies, we would live in a much different world. We would not be able to enjoy these products or the convenience they bring us.
