PVC thermal shrinkage (one traction rotation) film blowing machine
    PVC thermal shrinkage a traction rotating (printing) blown film machine. 2013 successfully developed novel blown film machine, a rotating traction is the original film after 180 ~ 320 degree rotation displacement. Make products to ensure smooth crepe, summer is not easy to generate critical reinforcement purpose, after four years of normal production, in 2016 after upgrading transformation, successful application technology patent products in 2017, known as "the second generation of blown film rotary unit" patent no. : 2016106453625
The company's new and improved design of screw and barrel can improve plasticization, increase the amount of extrusion, and reduce the inter-difference of water temperature control. A new generation of silicon controlled intelligent digital power adjustment control is adopted to achieve the balance of three-phase power grid and save 10 ~ 15% energy effectively.  Extend the service life of the heating rod
PVC heat shrinkage traction rotation is the original film through four levels of displacement rotation, equipped with deviation correction device, so that the second blowing to maintain a better straightness, product thickness more uniform, and to achieve the finished product will not produce a burst, improve the printing speed.Printing can reach 260-280 meters/min, is the current "PVC thermal shrinkage printing  film blowing machine" process reasonable machinery.
The technical indicators advanced machine, high precision, rational layout, novel structure, convenient operation of PVC printing film blowing equipment. Choose different models can be born finished width: 600-1200  mm, thickness: 0.02 -0.07 mm , shrinkage rate: MD: 3-5% TD: 45-50%, the unit production of shrink film is mainly used for label printing, after printing labels can be used in all kinds of drinks, skin care products, cosmetics and so on the thermal contraction close to packaging of all kinds of goods.
