Silage stretch films

PW masterbatch
Silage stretch films

Standard application profile & requirements

  • 15 to 25µm film thickness
  • Blown film extrusion mainly used in Europe, USA, and Canada
  • Cast film extrusion mainly used in the Middle East, Africa, APAC, LATAM and Mexico
  • 3 and 5 layers coextruded structures
  • Involves also Anti-UV & color masterbatches
  • Main cling solutions: PIB in masterbatch, liquid PIB and polyolefin elastomer

Required performances improved by a cling solution

  • Fast cling development to quickly deliver cling performances
  • Strong peel cling stregth properties to prevent the unwrapping of the film
  • High noise level to allows farmers to work continuously without visually monitoring the stretching process to while not necessary watching the process but hearing it
  • Good tack and retack properties to unwrap the film manually and wrap again
  • Slow cling development to strengthen the cling performance over time during season(s)
  • Strong lap cling strength for inter cohesion of film layers
  • Puncture resistance to prevent holes & tearing
  • O2 permeability resistance to conserve high nutritional values. It is important to create a closed space to present O2 from entering the bale
