PET sheet film is a type of plastic film made from polyethylene terephthalate, a polymer known for its strength, clarity, and versatility. It is widely used in packaging, printing, electronics, and other industries due to its excellent combination of physical and chemical properties. PET sheet film is available in various thicknesses, sizes, and finishes, making it suitable for a broad range of applications, from food packaging to protective coverings and labels.

What Are the Key Physical Properties?

One of the main advantages of PET sheet film is its strength and durability. It has high tensile strength, making it resistant to tearing and stretching under normal use. The material is also lightweight yet rigid, providing stability without adding unnecessary bulk. PET sheet film has excellent dimensional stability, meaning it maintains its shape and size under varying temperatures and pressures.

Additionally, PET sheet film offers good transparency and clarity, which makes it ideal for applications where visibility is important, such as packaging and display windows. The material can be easily cut, folded, and formed, allowing for flexible manufacturing processes. Its smooth surface also makes it suitable for printing and coating, enhancing its usability in graphic and labeling applications.

What Are the Chemical and Thermal Properties?

PET sheet film is chemically resistant to many acids, oils, and solvents, which makes it a reliable choice for packaging and industrial applications. It also has good thermal stability, allowing it to withstand moderate heat without deforming, which is important for processes like vacuum forming or heat sealing. The film is non-toxic and safe for use in food and beverage packaging, meeting regulatory standards in many regions.
