The reason why PET film (i.e. polyethylene terephthalate film) is highly favored by various industries is mainly due to its excellent performance in multiple aspects and wide application fields. The following is a detailed analysis:

Excellent physical and chemical properties

1. Mechanical properties: PET film has high mechanical strength, high tensile strength, excellent stiffness and impact resistance, which enables it to maintain stable shape and performance in various packaging and manufacturing processes.

2. Heat and cold resistance: PET film has good heat and cold resistance, and can maintain stable performance in high and low temperature environments, which makes it reliable for use in various extreme environmental conditions.

3. Chemical stability: PET film has good stability to various chemicals, including oil, acid, and alkali resistance, which makes it less prone to chemical reactions when in contact with various chemicals, ensuring the safety and stability of the product.

Environmental characteristics

1. Recyclability: PET film is a recyclable material that meets environmental requirements and helps reduce its impact on the environment. With the increasing awareness of environmental protection, more and more companies are choosing to use recyclable materials for packaging and production.

2. Low pollution: PET film generates relatively less pollution during production and use, meeting the requirements of green production.

Widely applicable fields

1. Food packaging: PET film has a wide range of applications in the field of food packaging, such as making bottle labels, heat sealed bags, etc. Its high transparency and good physical properties can effectively protect the freshness and hygiene of food.

2. Drug packaging: Due to its excellent wear resistance and high temperature resistance, PET film is suitable for drug packaging and can ensure the quality and safety of drugs.

3. Electronic product packaging: The high transparency of PET film makes it an ideal choice in the field of electronic product packaging, which can showcase the appearance of products and enhance their value.

4. Other fields: PET film can also be used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical grade mirror surface protection and other fields, with broad application prospects.

Technological progress and industrial chain optimization

1. Technological progress: With the continuous advancement of technology, the production process and performance of PET film have been continuously improved and optimized, making its application scope more extensive and in-depth.

2. Industry chain optimization: The improvement and optimization of the PET film industry chain also provide strong support for its development. The smooth operation of the entire industry chain, from raw material supply to production and processing, to product sales and recycling, provides a solid guarantee for the widespread application of PET film.

In summary, the reason why PET film is highly favored by various industries is due to its excellent physical and chemical properties, environmental characteristics, and wide range of applications. Meanwhile, technological advancements and industrial chain optimization have also provided strong support for the development of PET films.
