Casting film: referring to raw materials melted inside the extuders, the melt are extruded through narrwow opening (T-Die)and formed cookingly though the quench roller. Owing to the use of quench roller, it is realized of high production speed（triple or four times that of blowing films ） and high transparency,small thickness tolerance and the unique film transverse lengthways capacities.
The output of casting films in the developed countries fa exceeds that of blowing films.
Element： LDPE 2426 HDPE 2911 LLDPE 7042 FILLER
The advantages of the castinhg film:
Inculding high transparence, superior stiffness, excellent moisture-proof capacity, excelleng heat resistance,easy heat-sealing and high heat-sealing intension, because of which the casting films are occupying the more and more important position in the field of packing.
Application: packing for food, stationery, grocery,textiles and costume and used to compound with other flims as internal materials and so on.
