Antifog crosslinked shrink film JT05

In the production process of anti-fog cross-linked shrink film, how is the anti-fog agent added? What is the amount added? What is the impact of the type and performance of the anti-fog agent on the final product?

1. Anti-fog agent addition process
As a company focusing on the production of high-quality packaging materials, our company uses all imported high-quality raw materials, and strictly controls the quality at every step from materials to production process. In the production of anti-fog cross-linked shrink film, the anti-fog agent addition process is even more refined.
Raw material preparation: The company will prepare the raw materials required for the outer layer, core layer and inner layer according to production needs. These raw materials are strictly screened and inspected to ensure excellent quality.
Mixing and melting: After the raw materials of the outer layer, core layer and inner layer are mixed evenly, they are added to the extrusion equipment for melting. In this process, the anti-fog agent will be added to the core layer raw materials in a certain proportion to ensure the anti-fog effect.
Co-extrusion layer: The molten raw materials are co-extruded through the co-extrusion die to form a composite melt. In this process, the anti-fog agent will be evenly distributed in the core layer, laying the foundation for the subsequent anti-fog performance.
Blowing and shaping: The composite melt is blown once to form a film bubble. After the film bubble is cooled and shaped, a tubular film is formed. In this process, the antifogging agent will be further stably distributed in the film.
Cross-linking and stretching: The linear molecular chains of the tubular film are cross-linked by electron irradiation to improve the strength and stability of the film. After that, a secondary blow-up and longitudinal stretching are performed to form a composite film. In this process, the performance of the antifogging agent will be fully utilized.
Post-processing and winding: The composite film is shaped by post-processing (including annealing and cooling), and after trimming and winding, the final anti-fogging cross-linked shrink film is obtained.
2. The amount of antifogging agent added
The amount of antifogging agent added is one of the key factors affecting the anti-fogging performance of the final product. During the production process, the company will determine the amount of antifogging agent added according to the type, performance and specific needs of the product. Generally speaking, the amount of antifogging agent added will be between 1% and 15% of the total weight of the core layer raw material. This range is not fixed, but needs to be adjusted according to actual conditions. Through precise metering and addition, the uniform distribution and optimal performance of the antifogging agent in the film can be ensured.
3. The impact of the type and performance of the antifogging agent on the final product
Type:
Silicon-containing surfactant: has good lubricity and dispersibility, can reduce the surface tension of water, and make water droplets form a uniform water film on the surface of the film, thereby achieving an antifogging effect.
Boron-containing surfactant: has high heat resistance and stability, and can maintain antifogging performance at high temperatures.
Fluorinated surfactant: has excellent hydrophobicity and antifouling properties, and can significantly improve the cleanliness and antifogging performance of the film.
The company will choose the appropriate type of antifogging agent according to the specific needs of the product. For example, for packaging materials that need to withstand high temperature treatment, a boron-containing surfactant with better heat resistance will be selected; for packaging materials that need to maintain good cleanliness and antifouling performance, a fluorinated surfactant will be selected.
Performance:
Antifogging performance: The type and performance of the antifogging agent directly affect the antifogging effect of the final product. High-quality antifogging agents can maintain long-term antifogging performance at room temperature, making the items in the package clearly visible.
Transparency: The amount of antifogging agent added and the way it is used will also affect the transparency of the film. Excessive antifogging agent may cause the film to become blurred or produce other adverse effects. Therefore, it is necessary to accurately control the amount of antifogging agent added and the way it is used to ensure that the transparency of the film is optimal.
Stability: The stability of the antifogging agent is also one of the important factors affecting the performance of the final product. High-quality antifogging agents can maintain stable performance for a long time and are not easily affected by environmental factors. The antifogging agents selected by JT Company have been strictly screened and tested to ensure that they have good stability.
