HST-1 (SOW)
Structure
Treated, printable HS OPP layer
OPP Core
Slip Modified HS OPP Layer
Description
It is a co-extruded, both side heat sealable and one side treated Bi-axially Oriented Polypropylene film.
Features
- Excellent machinability
- Good ink adhesion
- Good heat seal strength
- Seals at low temperature, hence broader heat seal range
- Low COF through-out printing & laminating processes
Applications
- Soap over wrap application
- General purpose printing and pouching
