Blown film coextrusion line ALPHA GEO

for PPmultilayer

Alpha Marathon has developed, designed and produced numerous mono and co-ex blown film lines for agricultural, construction and geo membrane applications. Alpha provides the technology, experience and equipment to produce textured or smooth finish films. Textured films can be produced with a smooth edge for welding purposes when sealing the sheets together on site. Agricultural and geo membrane films typically can range from 10 mil up to a 100 mil profile thickness. Alpha has the capability to manufacture blown film dies up to 100” in diameter with downstream equipment ranging over 7000mm in width. Alpha’s unfolders and side slitting capabilities deliver an open sheet to the winder for a finished roll product. Agriculture Blown Film Line Typically manufactured of Polyvinyl Chloride (PVC), High-Density Polyethylene (HDPE), Low-Density Polyethylene (LDPE) and Polypropylene (PP). 
Depending on the composition, the membrane can be of potable or industrial grade, have outstanding dimensional stability, high puncture resistance, possess chemical resistance, environmental stress cracking resistance, and have an ability to contour to surface abnormalities.
