Over Wrap Film Transparent - Low COF & High Speed
HST-1(HSL)
Structure
Treated, printable HS OPP layer
Additive Modified 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 temperature range
- Low COF through-out printing & laminating processes
Applications
- General purpose printing, pouching and packaging of snacks, bakery products
- As a component in multi-layer laminate for VFFS & HFFS application
- High speed over wrap
