How thin can the in-mold labeled yogurt cup with thin-wall molding achieve?

 

 

The thinnest thickness achievable for thin-wall iml yogurt cups depends on various factors, including the chosen materials, manufacturing processes, and mold design. Generally, for thin-wall injection molding of yogurt cups, the thinnest part of the wall may range between 0.4 millimeters to 0.6 millimeters.

Key factors include:

  1. Material Selection: The use of specific plastic materials such as polypropylene (PP) or polyethylene (PE) allows for thinner wall thickness in thin-wall in-mold labeling. These materials typically exhibit good flow properties and molding performance.
  2. Injection Molding Process: Utilizing high-performance injection molding machines and precise control systems ensures uniform and stable thickness during thin-wall injection molding.
  3. Mold Design: The design of the mold is crucial for thin-wall injection molding. Precision molds ensure even material filling throughout the thin-walled section of the cup, preventing defects or uneven thickness.
  4. Cooling System: Efficient cooling systems are necessary for thin-wall injection molding to ensure rapid and uniform cooling after injection, preventing cup deformation or shrinkage.
  5. Production Environment Control: Controlling environmental factors such as temperature and humidity in the production environment is also essential for the success of thin-wall injection molding.

It is important to note that while achieving very thin wall thickness is technically feasible, practical applications need to consider cup stability, resistance to breakage, insulation properties, and other performance requirements. In actual production, a balance must be struck to meet technical specifications while ensuring the final product meets market demands.
