Description

Technical Field

[0001] This utility model relates to the field of thin film production, specifically a thin film cooling and forming device. Background Technology

[0002] Plastic films are ubiquitous in daily life and industrial production, resulting in ever-increasing demand. Cooling the thick film is a crucial step in the film production process. The cooling rate directly affects the crystallization state of the polymer. A suitable cooling method facilitates subsequent stretching and forming of the thick film, resulting in a final film product with excellent mechanical and optical properties (haze, gloss). However, existing plastic film production methods are inconvenient for adjusting tension as needed and suffer from poor cooling, negatively impacting user experience. Therefore, we propose a film cooling and forming device. Utility Model Content
