Application of Plastic Film Blowing Machine and Blown Film Process

The plastic film blowing machine produces plastic film that is ideal for a variety of high-quality packaging applications. This film is versatile and can be used for both light and heavy packaging due to its excellent properties such as barrier protection, freshness preservation, moisture resistance, frost protection, oxygen resistance, and oil resistance. It is suitable for packaging a wide range of items including fresh fruits, meats, pickles, fresh milk, liquid beverages, and medical supplies.


The process of blowing film using a plastic film blowing machine involves several steps: feeding the material into the hopper, plasticizing and extruding the material, blowing and pulling the film, cooling it with an air ring, using a herringbone clamp, pulling the film with a roller, and finally winding the film. It's important to note that the quality of the blown film is greatly influenced by the production process parameters. Therefore, it's crucial to closely monitor and regulate these parameters during the film blowing process to ensure smooth production and high-quality film products.
