PRODUCTS FEATURE

The 1000 Single Screw PP Film Blowing Machine is a professional single-screw dedicated extrusion equipment independently developed for PP polypropylene material processing. This 1000 Single Screw PP Film Blowing Machine adopts special screw and barrel structure designed exclusively for PP raw materials, solving the difficulty of PP plasticization and film forming, achieving stable, transparent and high flatness finished film production.

This 1000 Single Screw PP Film Blowing Machine can stably produce maximum 1000mm width PP film rolls, with adjustable thickness range, supporting mass production of various light to medium gauge PP films. Unlike ordinary PE film blowing machines, this PP dedicated film blowing machine uses up-and-down water cooling or horizontal cooling forming process, which makes the produced film have excellent transparency, high glossiness, good stiffness and uniform longitudinal and transverse tension, greatly improving the grade and added value of final products.

The whole machine is constructed with heavy-duty thick steel frame, equipped with high-precision frequency conversion speed regulation system, independent multi-zone automatic temperature control system and stable traction winding unit. Operation is simple and intuitive, one worker can operate multiple units at the same time, effectively saving labor cost. The 1000 Single Screw PP Film Blowing Machine runs with low noise, low failure rate, low energy consumption and long service life. It can be matched with printing machine, bag making machine to complete the whole production line from raw material to finished packaging bags.

The finished PP film produced by this 1000 Single Screw PP Film Blowing Machine is widely used in packaging of clothing, textiles, food, daily necessities, stationery, electronic products, etc. It is also the preferred raw film for producing PP flat bags, shopping bags, packaging sleeves, composite films and industrial inner lining films. This machine is deeply favored by domestic and overseas packaging manufacturers for its stable performance, high finished product rate, flexible parameter adjustment and outstanding cost performance, being the ideal choice for medium and large-scale PP film mass production.
