What is the job of a film blower?

according to the formula, plastic rice and color masterbatch are mixed, blowing, thickness adjustment, finished product blanking, weighing and warehousing.

1. Blow Membrane is a plastic processing method, which refers to a plastic processing technology in which plastic particles are heated and melted and then blown into thin films. Usually, polymer is extruded to form tubular film blanks, which are blown to the required thickness by high-pressure air in a good melt flow state, and then become thin films after cooling and setting.

2. The quality of the film blown by this processing technology is related to the film blowing machine and plastic particles. Its production equipment is simple, the investment is small, and the product takes effect quickly; The film has high mechanical properties; Boundless material, less waste; The film product is cylindrical, and the bag-making process is simple; And can produce large and wide films.

3. If the film is blown out with new materials, the color and luster are all balanced, and the finished product is well stretched. If plastic particles made of recycled waste plastics are usually added with pigments when they are made into films, the films may be unevenly colored, brittle and easily broken, and the price is low.

4. If the film blowing material produced by a professional film blowing machine is suitable for all kinds of high-grade film packaging. This kind of film can be widely used in light and heavy packaging because of its good barrier, fresh-keeping, moisture-proof, frost-proof, oxygen-proof and oil resistance.

5, such as all kinds of fresh fruits, meat, pickles, fresh milk, liquid drinks, medical supplies, etc. Unless a professional film blower or a film blower does not use the correct method in the processing, the film material made may also be inferior.

6. Most PE is used for blown film processing, and general low density PE(LDPE) or linear low density PE(LLDPE) can be used. HDPE film grade is generally used in places where superior stretchability and excellent impermeability are required. For example, HDPE film is often used in commodity bags, grocery bags and food packaging. PE film processing is generally carried out by ordinary film blowing processing or flat extrusion processing.
