What is PET Sheet?
PET (Polyethylene Terephthalate) sheet is an eco-friendly thermoplastic material known for its high transparency, excellent strength, superior barrier properties, and 100% recyclability. With the tightening of global environmental regulations, PET is rapidly replacing PVC and PS in various packaging applications, becoming the material of choice for sustainable packaging.
Key Advantages of PET Sheets in Packaging
- Food Safety Compliance – PET is a food-grade material free of harmful plasticizers, suitable for direct food contact.
- High Clarity – Over 90% light transmission, enhancing product visibility.
- Excellent Thermoformability – Ideal for vacuum forming, folding, and cutting.
- Eco-Friendly and Recyclable – 100% recyclable and meets RoHS/REACH standards.
- Outstanding Barrier Performance – Provides effective moisture and oxygen resistance.
