Heat Transfer Film For Protection Cases

PET thermal transfer film is a film material used to transfer patterns, text or logos on the surface of various protective shells. Through thermal transfer technology, the pre-printed pattern is transferred from the PET transfer film to the surface of the protective shell, which is widely used in the decoration and brand logo of various electronic product protective shells such as earphone shells, charger shells, and electronic cigarette shells.

Working principle
The working principle of PET thermal transfer film is to transfer the pattern from the transfer film to the surface of the protective shell by heating and pressure. The specific process is as follows:

Design and printing: Design the pattern according to the needs, and use special inks and processes to print the pattern on the PET transfer film.
Preheating stage: Heat the transfer film and the surface of the protective shell to a predetermined temperature in a heating device.
Transfer stage: The transfer film is tightly attached to the surface of the protective shell through a pressure device, so that the ink is transferred from the transfer film to the protective shell.

Cooling stage: After the transfer is completed, the surface of the protective shell is cooled, and the pattern is firmly attached to the surface of the shell.

Main features
High adhesion: Designed for electronic product protective shell materials (such as ABS, PC, silicone, etc.), it has excellent adhesion and the transfer pattern is not easy to peel off.
High durability: The transfer pattern has good wear resistance and durability, and can resist the wear and tear of the protective case in daily use.
High resolution: The transfer pattern is clear and colorful, and can present complex patterns and details.
Waterproof: The transfer pattern has good waterproof performance and is suitable for various environments.
Environmental protection: It uses environmentally friendly inks and materials, does not contain harmful substances, and meets environmental protection requirements.

Diversity: Various patterns can be designed according to different needs, suitable for protective cases of various shapes and sizes.

Application areas
Earphone case: used for decoration and brand identification of various earphone cases to enhance the appearance and brand recognition of the product.
Charger case: used for decoration and brand identification of charger cases to increase the beauty and recognition of the product.
Electronic cigarette case: used for decoration and brand identification of electronic cigarette cases to enhance the market competitiveness of the product.

Other electronic product cases: used for decoration and brand identification of other types of electronic product protective cases, such as mobile phone cases, tablet computer cases, etc.

Advantages
High efficiency: It can transfer on a large number of protective cases quickly and efficiently, suitable for mass production.
High quality: The transfer pattern is bright, clear, durable, and can resist wear and abrasions in daily use.
Flexibility: The transfer parameters can be adjusted according to different needs to adapt to protective shells of various sizes and materials.
Environmental protection: Environmentally friendly materials and processes are used to meet environmental protection requirements and reduce environmental pollution.

Economical efficiency: Thermal transfer technology has low cost and is particularly suitable for mass production with high economic benefits.

Precautions for use
Temperature and time control: According to the type of heat transfer film and the material of the protective shell, adjust the appropriate temperature and time to ensure the best transfer effect.
Equipment maintenance: Regularly check and clean the heating part and pressure device to ensure the normal operation and long life of the equipment.

Operation safety: Pay attention to protective measures during operation to avoid burns and other safety hazards.

Equipment requirements
Heating device: Used to heat the transfer film and the surface of the protective shell to ensure that the pattern can be successfully transferred.
Pressure device: Used to apply appropriate pressure during the transfer process to ensure that the transfer film fits tightly with the surface of the protective shell.

Control system: Used to set and control parameters such as temperature, time and pressure to ensure the accuracy of the transfer process.

Summary

PET thermal transfer film for earphone shells, charger shells, electronic cigarette shells and other protective shells is an efficient and environmentally friendly decoration and identification material. It transfers exquisite patterns and texts to the surface of various electronic product protective shells through thermal transfer technology. It is widely used in many fields such as earphone shells, charger shells, and electronic cigarette shells. Its high adhesion, high durability, high resolution and waterproofness make it an ideal choice for decoration and identification of modern electronic product protective shells.
