              Product Introduction

              Single screw barrel for blowing

              Blowing film screw barrel is mainly used in plastic film production industry. Films are widely used in packaging, agricultural mulching films, architectural films, industrial films and other fields. The blown film screw barrel is blown into a film through a die after heating and melting plastic particles. Its applications include but are not limited to the following:

              Packaging film: The plastic film produced by the film blowing machine can be used for food packaging, daily necessities packaging, etc. These films have good moisture-proof, light-shielding, and tear-resistant properties, which can protect and extend the shelf life of products and ensure product quality.

              Agricultural mulch film: The agricultural mulch film manufactured by the film blowing machine is used for farmland covering, greenhouse covering and other occasions. These films can provide functions such as heat preservation, moisture retention, and anti-ultraviolet rays, helping crops improve yield and quality, while reducing soil moisture evaporation and weed growth.

              Architectural membrane: The architectural membrane manufactured by the film blowing machine is mainly used in temporary buildings, waterproof and moisture-proof materials, etc. These membranes have good water resistance, moisture resistance, wind resistance and other properties, which can effectively protect building structures and improve building quality and service life.

              Industrial film: Industrial film manufactured by film blowing machine is widely used in various industrial fields, such as electronic products, auto parts, building materials, etc. These films can be used for surface protection, isolation, dustproof and other functions to ensure the quality and appearance of the product.
