Heat Transfer Film For Food Container

PET thermal transfer film for food packaging is a film material specially used for transferring patterns, text or logos on the surface of food packaging containers. Through thermal transfer technology, the pre-printed pattern is transferred from the PET transfer film to the surface of various food packaging containers, and is widely used in the decoration and brand identification of food barrels, food boxes, food cans, food bottles, etc.

Working principle
The working principle of PET thermal transfer film for food packaging is to transfer the pattern from the transfer film to the surface of the food packaging container 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 food packaging container to a predetermined temperature in a heating device.
Transfer stage: The transfer film is tightly attached to the surface of the container through a pressure device, so that the ink is transferred from the transfer film to the container.

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

Main features
High adhesion: Designed for food packaging materials (such as plastic, glass, metal, 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 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.
Food safety: It uses food-grade environmentally friendly inks and materials, does not contain harmful substances, and meets food safety standards.

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

Application areas
Food barrels: barrels used for food storage and transportation, such as candy barrels, milk powder barrels, etc. Decoration and brand logo.
Food boxes: boxes used for food packaging, such as biscuit boxes, chocolate boxes, etc. Decoration and logo.
Food cans: cans used for food storage, such as tea cans, coffee cans, etc. Decoration and logo.

Food bottles: bottles used for liquid or granular food packaging, such as juice bottles, seasoning bottles, etc. Decoration and logo.

Advantages
High efficiency: can quickly and efficiently transfer on a large number of food packaging containers, 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 food packaging containers of various sizes and shapes.
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 transfer film and the material of the food packaging container, 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 food packaging container 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 to the container surface.

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 food packaging is an efficient and environmentally friendly decoration and identification material. It transfers exquisite patterns and texts to the surface of various food packaging containers through thermal transfer technology. It is widely used in food barrels, food boxes, food cans, food bottles and other fields. Its high adhesion, high durability, high resolution and food safety characteristics make it an ideal choice for modern food packaging decoration and brand identification.
