Blown Film Making Machine Line, 146 - 194 ( Kw )

Product Details

The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line.This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow. Spider dies consist of a central mandrel attached to the outer die ring via a number of "legs"; while flow is more symmetrical than in annular dies, a number of weld lines are produced which weaken the film. Spiral dies remove the issue of weld lines and asymmetrical flow, but are by far the most complex.AdvantagesBlown film generally has a better balance of mechanical properties than cast or extruded films because it is drawn in both the transverse and machine directions. Mechanical properties of the thin film include tensile and flexural strength, and toughness. The nearly uniform properties in both directions allow for maximum toughness in the film .Blown film extrusion can be used to make one large film, two smaller ones, or tubes that can be made into bags. Also, one die can make many different widths and sizes without significant trimming. This high level of flexibility in the process leads to less scrap material and higher productivity. Blown films also require lower melting temperatures than cast extrusion. Measured at the die opening, the temperature of cast film is about 220°C., where as the temperature of blown film is about 135°C. Furthermore, the cost of the equipment is approximately 50% of a line.  DisadvantagesBlown film has a less effective cooling process than flat film. Flat film cooling is done by means of chill rolls or water., which have significantly higher specific heat capacities than the air that is used in the blown film cooling process. The higher specific heat capacity allows the substance to absorb more heat with less change in the substance temperature. Compared to cast film, blown film has a more complicated and less accurate method to control film thickness; cast film has a thickness variation of 1 to 2% versus the 3 to 4% for blown film. The resins used for casting typically have a lower melt flow index, which is the amount of polymer that can be forced through a standard die in 10 minutes according to a standard procedure. The melt flow index for cast film is about 5.0 g/10 min where as for blown film it is about 1.0 g/10 min. Consequently, the production rates for cast film are higher: cast film lines can reach production rates of up to 300m/min where as blown film lines are usually less than half this value. And finally, cast film has better optical properties, including transparency , haze, and gloss.Additional Information Delivery Time 90 Days Port Of Dispatch Mundra, Gujarat Production Capacity 28 - 280 ( kg/hr ) Payment Terms L/C (Letter of Credit),T/T (Bank Transfer),Other Interested in this product?Get Latest Price from the sellerContact SellerAbout the CompanyYear of Establishment2006Legal Status of FirmLimited Company (Ltd./Pvt.Ltd.)Nature of BusinessManufacturerNumber of Employees26 To 50 PeopleAnnual TurnoverRs. 10 - 25 CroreIndiaMART Member SinceNov 2008GST24AABCO9372R1ZPImport Export Code (IEC)08140*****We, Ocean Extrusions Pvt.
