Product Description

  PVC thermal shrinkage a traction rotating (printing) blown film line. Was successfully developed in 2013 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 reinforced its purpose, after two years of normal production, after upgrading transformation in 2016, 2017 successful application technology patent product, known as "the second generation of blown film rotary unit (patent for utility model. Patent no. : ZL201620854318.0)
Our company has improved the design of screw and barrel, improved the plasticization, increased the amount of extrusion, reduced the temperature difference, adopted the new generation of SCR intelligent digital power adjustment control, reached the three-phase power grid balance, more effective in energy saving 10-15%, also can extend the service life of the electric 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 stage 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 + 2 mm, thickness: 0.02 0.07 mm + / - 3 mm, shrinkage rate: longitudinal: 3-5 plus or minus 1% transverse: 45 to 50 plus or minus 2%, 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.
