PET

PET film, also known as polyester film, is a versatile and widely used packaging material. It possesses excellent mechanical, optical, and barrier properties, making it suitable for various applications in packaging, electronics, and industrial sectors. Thanks to its stiffness and temperature resistance, PET helps pouches keep a premium appearance on shelf while protecting graphics.

Engineering Insights

Advantage

Transparency & Gloss

Superior clarity results in more vibrant colors for the printing layer.

Advantage

Mechanical Performance

Best toughness among thermoplastics with high tensile and impact resistance.

Advantage

Heat & Chemical Resistance

Stable up to 250°C, ensuring accuracy in high-temp processes.

Limitation

Alkali Sensitivity

Not resistant to strong alkalis; caution with high pH powders.

Limitation

Static Electricity

Prone to static buildup which can affect filling processes.

Practical Usages

Printing Layer

Typically the outermost layer due to clarity and heat resistance.

High-Temp Packaging

Used for microwave or oven-ready bags (PET/HSPET).
