Extrusion blown film machines offer a core advantage: efficient, continuous production, enabling the cost-effective production of seamless tubular films. However, their disadvantages include the difficulty in controlling film thickness uniformity and limited adaptability to certain raw materials. While efficient, continuous, and cost-effective, they can produce seamless tubular films (suitable for bag making, etc.), their thickness control accuracy is inferior to cast film, and they have certain raw material limitations (e.g., they are not suitable for producing films made of brittle materials).
