3. Determine whether your product is a roll single-layer or double-layer film, that is, whether it is made as a bag or a sheet film, and determine whether double winding is needed.
4. Determine how many threads the thickness of your product should reach in order for the manufacturer to provide an accurate configuration
5. Choose the high and low end configurations of the blown film machine, including automatic lifting, automatic screen changing, automatic material suction, inflatable shaft winding, fully automatic winding, surface treatment, etc.
