With the continuous advancement of technology, BOPET polyester film has found myriad uses across multiple sectors. With properties making it suited for a diversity of applications, it has joined the packaging, printing, electronics, electrical, and solar industries as a valuable material. So, what key roles does BOPET polyester film fulfill?

1. Packaging field

BOPET polyester film has a wide range of applications in the packaging field.

In terms of food packaging, BOPET polyester film can effectively block oxygen, water vapor, and odors, extending the shelf life of food. For example, packaging for cookies, candies, tea leaves, etc., can maintain the freshness and taste of food. BOPET polyester film has good transparency, which allows consumers to clearly see the food inside the packaging and increases the attractiveness of the product. In addition, it also has a certain mechanical strength, which can withstand certain pressures and impacts, protecting food from damage during transportation and storage.

In terms of pharmaceutical packaging, BOPET polyester film can be used for packaging pharmaceutical tablets, capsules, etc. It can ensure the quality and safety of drugs and prevent them from being affected by the external environment. BOPET polyester film has good chemical stability, does not react with drugs, and also has good barrier properties, which can prevent the volatilization of active ingredients in drugs and the invasion of external impurities.

BOPET polyester film also plays an important role in the packaging of daily chemical products. It can be used for packaging shampoo, shower gel, cosmetics, etc., protecting products from external environmental influences while also showcasing the brand and features of the product. BOPET polyester film has good corrosion resistance and wear resistance and can withstand chemical substances and friction in daily chemical products.

BOPET polyester film fulfills a vital protective function alongside a prominent presentation purpose for electronic goods packaging. It can shield mobile phones, tablets, as well as cameras from harm amidst shipment and storage by being utilized for product covering. BOPET polyester film possesses superb clarity as well as gloss, permitting buyers to clearly see the electronic products inside the packaging and increasing the attractiveness of the product.

2. Printing industry

BOPET film has many advantages as a printing substrate.

The surface flatness and smoothness of BOPET film are high, which can make printed patterns clearer, brighter, and more delicate, with high color reproduction. Therefore, it is commonly used to produce various printed materials such as labels, posters, brochures, etc. Compared with other printing substrates, BOPET film has better printing effects and can meet the needs of high-end printing.

In addition, BOPET film has high mechanical strength and is not easily stretched or deformed during the printing process, ensuring the accuracy and stability of printing dimensions. This is very important for products that require high-precision printing. BOPET film also has good water resistance and chemical resistance, which can maintain the quality of printed patterns in different environments.

3. Electronic and electrical field

BOPET polyester film also has important applications in electronic and electrical fields.

As an insulation layer for wires and cables, BOPET polyester film has excellent insulation performance and mechanical protection. It can prevent short circuits, leakage and other faults in wires and cables during use, and can also withstand certain mechanical stresses to protect wires and cables from damage.

In capacitors, BOPET polyester film is used as a dielectric and insulation layer. Its high dielectric constant and low loss factor can meet the high-performance requirements of capacitors, improving their capacity and stability.

BOPET polyester film can also be used to make protective films for electronic components, flexible printed circuit boards, etc. It can protect electronic components from external environmental influences and improve the reliability and service life of electronic components. Meanwhile, BOPET film has good flexibility and can adapt to electronic components of different shapes and sizes.

4. In the field of solar cells

BOPET film also has a wide range of applications in solar cells.

It can be used as a backing material for solar panels, with characteristics such as UV resistance, high-temperature resistance, and good weather resistance. Unlike some core components possessing single qualities, BOPET polyester film manifests a plethora of protective properties. Shielding the core components of solar cells from detrimental exterior forces safeguards solar cells' functionality while expanding usable life expectancy. Compared to other back sheet materials, BOPET film epitomizes superior performance and can meet the requirements of solar cells in different environments.

5. Summary

In summary, BOPET polyester film has a wide range of applications in packaging, printing, electronic and electrical, and solar cell fields. It has good physical, chemical, and optical properties, which can meet the needs of different fields.
