I. Basic Definition: What is PET?

PET, or polyethylene terephthalate, is a common resin material in daily life. It possesses excellent mechanical properties, resistance to high and low temperatures, gas barrier properties, food safety, and good flame retardancy (self-extinguishing), making it widely applicable in various fields such as food packaging, electronic components, and electrical insulation.

II. Key Characteristics of PET Sheets and Rolls

1. Raw Material Source
   PET is derived from petroleum, a non-renewable resource.

2. Performance Features
   As a virgin material, PET offers high purity and stable performance. It exhibits exceptional mechanical strength, high transparency, resistance to high and low temperatures, good flame retardancy (self-extinguishing), and strong hygiene and safety standards, making it suitable for direct food-contact packaging.

3. Cost and Price
   The price of PET is significantly influenced by fluctuations in international oil prices.

   
   

III. Main Application Areas of PET: High-Purity and High-Stability Advantage Scenarios

1. Packaging Industry
   Leveraging its high transparency, PET is commonly used to manufacture mineral water bottles, beverage bottles, cake boxes, fruit trays, and more. It is also extensively used in non-food industrial packaging for cosmetics, electronic products, etc.

2. High-Performance Films and Electrical Fields
   PET films, due to their excellent electrical properties and flame-retardant characteristics (self-extinguishing), are primarily used as electrical insulation materials, photographic film bases, and various substrate tapes.

3. Precision Injection-Molded Components
   Due to its heat resistance and fire safety properties, PET is often used in automotive parts, electronic appliance housings, and internal structural components. Its stability also makes it suitable for precision electronic components such as connectors and terminals.

   
   

IV. PET Material Selection Guide

PET is the preferred choice when products demand exceptionally high requirements for transparency, mechanical strength, temperature resistance, fire safety, and hygiene/safety standards—particularly for direct food contact or applications in high-performance engineering and electrical scenarios—thanks to its stable virgin material properties.

V. Conclusion: An Irreplaceable Performance Foundation

With its reliable, stable, and excellent overall performance, PET material plays an indispensable role in modern industry and daily life. Its self-extinguishing flame-retardant property further expands its applications in fields with stringent safety requirements, such as electronics, electrical engineering, and transportation. In application areas that pursue ultimate quality and guaranteed safety standards, PET remains a fundamental material that is difficult to replace today. Choosing PET means choosing a proven guarantee of performance and safety validated by the market over time.
