Brief introduction on the three layer coextrusion film blowing machine

  Blown film process: hopper feed material extrusion, blown traction, the wind ring cooling, spica splint, traction and traction, cutting edge, film rewinding. In order to meet the production process of plastic film packaging material some special functional needs, a variety of material properties (such as breathable, waterproof, thermal insulation and toughness) blown and coextrusion together to form multifunctional plastic film, multi-layer co extrusion film blowing machine is developed.

  Three layer coextrusion film blowing machine in the domestic market, the 2010 plastic machinery output value reached 188.73 billion yuan, a growth rate of 18%, extrusion machine products reached 18 254 units (sets). The total output value of 3 billion 870 million yuan class extruder. The purpose of multi-layer co extrusion film blowing machine is to play the advantages of a variety of materials, to avoid some of the shortcomings of a single material or monolayer film blowing machine.

  Five layer co extrusion film blowing machine, mainly used in HDPE, MHDPE, LDPE, LLDPE and mLLDPE, PA and EVOH, with gas barrier properties of the resin, production of the film is mainly used for packaging, high-grade food bag, vacuum bag, liquid packaging bags and other packaging materials, to flavor preservation, preservation, anti-corrosion, airtight, extend the shelf life of the package to.

  Three layer coextrusion blown thin production line using a new type of high efficiency and low energy consumption extrusion unit, IBC film bubble cooling system, + 360 degree horizontal traction rotation system, photoelectric automatic correction device, automatic collection film roll and tension control, computer screen automatic control systems and other advanced technologies. Such as a variety of fresh fruits, meat dish, pickles, fresh milk, liquid beverage, pharmaceutical products etc.. The film produced with high transparency, resistance to puncture, high toughness, low temperature and high temperature, good composite fastness, anti curl.

  The Middle East, South America, the CIS and countries in Southeast Asia plastic machinery market, in recent years also gradually open, due to institutional reasons, situation of each country's economic development is different, need plastic machinery are not the same, and high-grade, high performance film blowing machine (price in more than 100 million yuan accounted for only about 100 units) accounted for only total share of about 1%.

  In the high-grade plastic above, it can be said is a piece of virgin land has yet to be people to develop, want domestic plastic machinery manufacturing enterprises, seize the opportunity, enterprising, to develop the enormous potential of the domestic and foreign plastic machinery market, make their own businesses have greater development.
