PET (Polyethylene Terephthalate) is a high-performance polymer with unique advantages in the carrier tape field. It combines high strength and excellent toughness, overcoming the shortcomings of traditional materials like PS in certain applications (insufficient strength or brittleness), and is gradually becoming a new choice for high-end electronic packaging materials.

1. High Strength and Physical Protection

PET material is renowned for its excellent Tensile Strength, providing reliable physical protection for electronic components. This high strength and flexibility ensure that the carrier tape does not easily break or deform during high-speed winding, transport, and placement. When subjected to strong external impacts, PET material also has a certain buffering elongation capability, offering a higher level of protection for components.

2. Superior Optical Properties and Environmental Resistance

PET carrier tape possesses excellent optical performance and environmental adaptability:

• High Transparency: PET material is clear and transparent, facilitating precise positioning and recognition by the vision systems of SMT placement machines, reducing mis-pick rates.
• Weather Resistance: Using high-quality polymers as raw materials, PET has superior weather resistance, maintaining good dimensional stability between -50°C and 100°C, with a melting point around 260°C.
• Moisture Resistance: Unlike some traditional packaging materials that degrade in performance due to moisture absorption, PET carrier tape maintains its strength with minimal decay even in humid environments.

3. Environmental Protection and Economic Benefits

As companies increasingly value sustainable development, the environmental attributes of PET material have become a significant competitive advantage:

• Eco-friendly: PET is widely used in food and textile industries and is fully recyclable.
• No Contamination Risk: It does not rust like steel bands when exposed to air or moisture for long periods, eliminating the risk of rust contamination on packaged goods.
• Economy: Due to the low density and high strength of PET, the length of PET carrier tape per unit weight far exceeds that of other materials, offering higher economic efficiency in storage and usage.
