Characteristics of Roll PET Film
Characteristics of Roll PET Film – PET Film Coating – Cheersonic
Roll PET film possesses the following material characteristics:
1. Physical Properties:
High Mechanical Strength: It exhibits high tensile strength and elongation at break. High tensile strength means it can withstand significant tensile forces without easily breaking, maintaining good integrity during winding, unwinding, and subsequent processing and use. For example, in packaging applications requiring tensile strength, PET rolls adapt well to this stress environment and are less prone to breakage.
Good Dimensional Stability: PET film exhibits minimal dimensional change under varying temperature and humidity conditions. This is crucial for applications requiring precise dimensional control, such as electronic device packaging and optical films, ensuring product accuracy and stability.
Good Stiffness: Roll PET film possesses good stiffness, resisting bending and deformation, and maintaining good flatness. This allows it to maintain its shape during storage, transportation, and processing, facilitating handling and use.
2. Chemical Properties:
Good Chemical Resistance: It exhibits good resistance to many chemicals such as acids, alkalis, and organic solvents, and is not easily corroded or damaged by these chemicals. Therefore, PET rolls have wide applications in complex chemical environments, such as chemical product packaging and laboratory protection.
Strong Oxidation Resistance: PET rolls exhibit good oxidation resistance in air, resisting oxidation reactions that lead to aging and performance degradation. This results in a long service life, maintaining good performance over extended periods.
3. Optical Properties:
High Transparency: High transparency clearly reveals patterns and colors beneath the film, allowing packaged or covered items to be clearly seen. For example, in food and pharmaceutical packaging, the high transparency of PET rolls allows consumers to see the contents directly, increasing product credibility and appeal.
Good Gloss: High surface gloss reflects a dazzling light, enhancing the overall decorative effect and visual appeal. In applications with high aesthetic requirements, such as high-end packaging and decorative materials, the gloss of PET rolls adds to the product’s aesthetic appeal.
4. Thermal Properties:
Good Heat Resistance: Long-term operating temperature can reach 120℃, maintaining stable performance even at high temperatures and resisting deformation and softening. This makes PET rolls highly adaptable to applications requiring high-temperature processing or use in high-temperature environments, such as heat-sealing packaging and welding of electronic components.
Low Heat Shrinkage: It exhibits a low heat shrinkage rate at room temperature, maintaining good dimensional stability. However, with special processing, PET rolls with higher heat shrinkage rates can be produced for heat-shrink packaging and other applications.
5. Processing Performance:
Easy to Mold: It possesses good plasticity and processing properties, easily undergoing bending, stretching, and hot pressing to adapt to various complex shapes and structural requirements. For example, PET rolls can be processed into various containers, bags, labels, and other products.
Easy to Print: The surface has good adhesion to inks and other printing materials, easily printing various patterns, text, and logos to meet diverse printing needs. Therefore, PET rolls are widely used in packaging, advertising, and printing.
6. Environmental Performance:
Recyclability: It is a recyclable and environmentally friendly material. Recycled PET material can be further processed and used to manufacture other plastic products, reducing environmental pollution and meeting the requirements of sustainable development.
Non-toxic and Odorless: It does not produce harmful substances during production and use, is harmless to humans and the environment, and is a safe and reliable material.
The roll to roll ultrasonic spraying machine has high adaptability and high-precision coating characteristics for coating PET film materials. It is suitable for the substrate properties of PET film, such as light and thin, flat surface, and moderate temperature resistance. It adopts non-contact atomization coating to avoid stretching and scratching damage to the coil, ensuring the integrity of PET film raw materials. Its ultrasonic atomization forms micron level fine mist, and the coating has good spreading on the surface of PET film, without defects such as pinholes, shrinkage holes, and sagging. The dry film thickness accuracy can reach ± 5%, and the surface density uniformity is excellent. The adhesion between the coating and PET film is strong, and it is not easy to peel off or curl. The equipment can match the continuous winding speed of the coil, achieve integrated coating, adapt to various coating systems such as water-based and solvent based, and meet different PET film coating needs. The coating process has a high utilization rate of the coating, no excessive spraying waste, and uniform atomization dispersion. The efficiency of the subsequent drying process is improved, and it is suitable for the large-scale and high-precision coating production of PET films in the fields of optics, electronics, packaging, etc.
