http://www.gcstamping.com/mold-design/blow-mold/ Description Film blowing is a plastic processing method, which refers to a plastic processing process that heats and melts plastic particles and then blows them into a thin film. Generally, a polymer is extruded into a tubular film blank, which is passed through high pressure in a good melt flow state. The air inflates the tube film to the required thickness, and becomes a film after cooling and shaping.

This film is widely used in light and heavy packaging due to its good barrier properties, freshness, moisture, frost, oxygen and oil resistance. Such as a variety of fresh fruits, meat food, pickles, fresh milk, liquid drinks, medical supplies and so on. If a non-professional film blowing machine or film blowing machine does not use the correct method during processing, the film material produced may also be inferior. Most PE is used for blown film processing film, and general low density PE (LDPE) or linear low density PE (LLDPE) are available. HDPE film grade is generally used where excellent stretchability and excellent barrier properties are required. For example, HDPE film is commonly used in merchandise bags, grocery bags, and food packaging. PE film processing generally uses ordinary blown film processing or flat extrusion processing.China Blow Mold website:http://www.gcstamping.com/mold-design/blow-mold/
