Silage stretch films - PW

Silage stretch films

PW masterbatch

Standard application profile & requirements

15 to 25µm film thickness
Blown film extrusion mainly in Europe, USA, and Canada
Cast film extrusion mainly in Middle East, Africa, APAC, LATAM and Mexico

3 and 5 layers coextruded structures
Involves as well Anti-UV & color masterbatches
Main cling solutions: PIB in masterbatch, liquid PIB and polyolefin elastomer

Required performances impacted by a cling solution

Fast cling development to quickly deliver cling performances

Strong peel cling stregth properties to prevent unwrapping

High noise level to allow farmes working while not necessary watching the process but hearing it

Good tack and retack properties to unwrap manually and wrap again

Slow cling development to strengthen cling performances over time during season(s)

Strong lap cling strength for inter-cohesion of film layers

Puncture resistance to prevent holes & tearing

O2 permeability resistance for high nutritional values. It is important to create a closed space and not permitting O2 to enter the bale
