Why does the surface of shrink film become hazy or cloudy after heat shrinking—and how can it be fixed?
During heat shrink packaging, the film surface may become hazy or appear foggy. Solutions include:

• Lower the temperature of the heat shrink packaging machine—excessive heat is a primary cause of film fogging.
• Increase the conveyor speed of the shrink wrapping machine to reduce the duration of heat exposure, minimizing thermal degradation that leads to cloudiness.
