SJ-55（40、60、70）聚丙烯旋轉模頭吹膜機適用于吹制聚丙烯（PP）塑料薄膜，廣泛應用于食品、服裝、紡織品、日用品等民用品和工業品的包裝。

特點： 1、模頭能360左右旋轉，可增強塑料薄膜的強度和均勻度。 2、螺桿、料筒均采用38CRMOALA合金鋼，經氮化處理和緊密加工而成，硬度高，耐腐蝕性強，經久耐用。 3、模頭鍍硬鉻，其結構為螺旋芯軸式，擠出的熔料均勻，吹制的薄膜光潔度好；風冷裝置結構為迷宮型，出風量均勻，采用循環水冷卻，從而使吹制的薄膜達到的透明度。 4、卷取裝置采用壓力摩擦收卷或中心收卷，采用力矩電機調節，收卷平整，換卷方便。 Use: The machine is suitable for producing PP. it is widely be used for packing food, garment, textile, daily necessaries and industrial product etc. Characteristics:

1. • 1.       Die head can be turned 360°, it can strengthen the tension and evenness degree of film.
   • 2.       Screw stem and cylinder are all made of 38CRMOALA alloy, and treated by nitrogen. It has an advantage of great thickness,
     corrosion resistance and endurance etc.
   • 3.       Die head has been chromized, it’s advantage of screw core structure, melting material extruding evenly, and blowing film smoothly
     etc. cooling equipment is a labyrinth blow pump which has good effect. Especially, it adopts the recycling cooling water system to ensure
     the best transparent effect.
   • 4.       Discharging equipment adopts pressing braking winding equipment& central winding equipment, and it adopts torque motor to
     adjust, has the merits of smooth film, convenience operation.
