1. Extrusion process:
The production of 3D PET film starts with the extrusion process. In this process, PET resin pellets are melted and extruded through a flat die to form a continuous sheet of molten polymer. The sheet is then cooled and solidified to form a thin film.
2. Stretching process:
After the extrusion process, the film is subjected to a stretching process. This involves stretching the film in both the machine direction (MD) and transverse direction (TD) simultaneously. The stretching process aligns the polymer chains in multiple directions, resulting in a three-dimensional structure that enhances the film’s properties.
3. Coating process:
Once the film is stretched, it can undergo a coating process if required. This involves applying a thin layer of coating material onto one or both sides of the film. The coating can provide additional functionalities, such as improved adhesion, scratch resistance, or UV protection.
1. Raw materials:
The quality of 3D PET film is highly dependent on the quality of the raw materials used. The PET resin should have consistent properties and meet specific requirements for clarity, strength, and dimensional stability. Any impurities or variations in the resin can affect the final film’s performance and appearance.
2. Processing conditions:
The processing conditions during the extrusion and stretching processes play a crucial role in determining the quality of 3D PET film. Factors such as temperature, speed, and tension need to be carefully controlled to ensure uniform stretching and prevent defects like wrinkles or tears.
