Do you know what PP, PE, and PET mean on food packaging?

Differences Between PP, PE & PET Plastics

• PP (Polypropylene) offers good heat resistance and chemical resistance, but has relatively low toughness and transparency. It is widely used for rigid materials and fibers.
• PE (Polyethylene) features excellent toughness and flexibility, but low rigidity and heat resistance. It is commonly used for flexible products and films.
• PET (Polyethylene Terephthalate) provides high transparency, good toughness, and heat resistance, making it ideal for bottles, containers, and packaging.
