Japan Toray PET film :

Performance characteristics

Physical properties

High transparency: It has extremely high transparency, and the light transmittance can reach more than 98%, making the package contents clearly visible. It is also suitable for optical fields with high transparency requirements.

High mechanical strength: It has high tensile strength, good tensile resistance, is not easy to break and tear, has good toughness, can withstand a certain degree of stretching, bending and impact, can protect the packaged items or withstand various mechanical stresses in industrial applications.

Good dimensional stability: Under different temperature and environmental conditions, the size changes very little, and can maintain a stable shape and size, ensuring the precision requirements in various applications, such as in the manufacture of electronic components, it can ensure the precise fit of the film and components.

Chemical properties

Strong chemical corrosion resistance: It has good tolerance to weak acids, organic solvents, etc., is not easily corroded by chemicals, and can be used to package products containing chemicals, or as a protective material in a chemical environment.

Good water resistance: low water absorption, can maintain good performance in a humid environment, will not expand, deform or reduce strength due to water absorption, can be used for packaging or protection in a humid environment.

Electrical properties

Excellent insulation performance: has good electrical insulation performance, is less affected by temperature, can effectively prevent current leakage and short circuit, and is widely used in the insulation materials of electronic and electrical fields, such as insulation of motors, transformers, circuit boards, etc.

Thermal properties

Good heat resistance: can withstand a certain high temperature, can be used in a high temperature environment, some types of PET film can withstand high temperatures up to 260℃, suitable for occasions that require high temperature processing or work in a high temperature environment.

Low heat shrinkage: stable size at high temperature, secondary shrinkage close to zero, can still maintain excellent flatness after heating, which is conducive to application in high temperature processes, such as thermal transfer, thermoforming, etc.

Application fields

Electronic field: It can be used to manufacture membrane switches, flexible printed circuits, insulating sheets, glue coating, etc., to provide protection for the performance and quality of electronic products, and can also be used as packaging materials for electronic components to play a protective and insulating role.

Packaging field: It is widely used in the packaging of food, medicine, cosmetics, daily necessities, etc. Its excellent transparency, barrier properties and mechanical properties can effectively protect the product, extend the shelf life, and enhance the product's appearance.

Optical field: Such as diffusion film base, micro-transparent film base, brightening film base, etc., using its high transparency and good optical properties, it can improve the optical display effect and improve the display quality.

Magnetic material field: It is used for motor insulation, large transformers, etc., which can provide good insulation and mechanical protection to ensure the normal operation and safety of magnetic materials.

Other fields: It can also be used in solar backlight panels, building window films, automotive interiors, magnetic tape black slip paper, electro-acoustic equipment, adhesive tapes and other fields to exert its various excellent properties.
