Blowing film is a kind of plastic processing method, which refers to the process of heating and melting plastic particles and then blowing them into thin films. The quality of the film material blown out by this process is related to the machine and plastic particles blown by this process.

If the film is blown out with new material, the color is uniform, clean and the finished product is well stretched. If the plastic particles made from recycled waste plastics are usually added pigments to the film, the film may be unevenly colored, brittle and fragile, and the price is lower.

If blown film material produced by professional blower is suitable for all kinds of high-grade film packaging. Because of its good barrier, fresh-keeping, moisture-proof, frost-proof, oxygen-proof and oil-proof, the film can be widely used in light and heavy packaging. Such as all kinds of fresh fruits, meat products, pickles, fresh milk, liquid drinks, medical supplies and so on.

If the non-professional blower or blower does not use the correct method in the processing, then the film material may be inferior. Most PE is used for blown film processing. Universal low density PE (LDPE) or linear low density PE (LLDPE) are available. HDPE film grade is generally used in areas requiring superior tensile properties and excellent impermeability.
