Corona treatment is required on
Extrusion coating/Lamination plant For better
adhesion of thin layer of polyolefin's (Mainly LDPE
/ PP) on substrates like Paper, Cotton Cloth, Woven
fabrics, Jute fabric, Aluminum foil, BOPP film,
Polyester film, etc. Paper, Cotton Cloth, Woven
fabrics, Jute fabric, Aluminum foil, BOPP film,
Polyester film, etc has to be corona treated before
coating to achieve better bonding .
Corona treatment system is a very
effective way to increase the surface tension of
virtually any material. Surface treatment is
required for woven fabrics whose normal surface
tension is not sufficiently high to permit good
wetting , corona treatment increases bonding.
