If you are confused by all of the abbreviations that can be found on the bottom of takeaway food containers & plastic cups, you are not alone. All consumers might like to learn the differences, but this is certainly the case if you are considering starting a business that will be using these types of plastic containers, especially takeaway containers for foods or drinks. Two of the most popular types of plastic used in these containers today are PET or Polyethylene terethalate and PP or Polypropylene. Although both types of plastic are recyclable and used often in the food industry, there are some important differences that you might want to consider.
PVC, or polyvinyl chloride, is a widely used plastic that contains carbon, hydrogen, and chloride. This type of plastic can be found everywhere in our everyday lives. You can find it in some objects like medical devices, credit cards, pipes for water and gas, and children’s toys. It is safe for food and water, in fact, PVC is what most plastic cutting boards are made out of.
Polyethylene Terephthalate, also known as PET, is a strong, lightweight, shatter-resistant plastic resin commonly used to create thermoformed packaging designs. Featuring excellent clarity and the ability to take on colorants very well, it’s also great for helping people see your product.
PET provides a strong barrier against water vapor, dilute acids, gases, oils, alcohols, and most importantly, UV rays. These qualities make it perfect for creating food-safe containers, water bottles, packages for electronics, retail designs, and more.
PP is a thermoplastic polymer used in a variety of applications. It’s scientific name is polypropene. You can find this plastic being used to package things like yogurt, medicine, drinks, and condiments.
