Description:

Very Low SIT CPP Film with extremely Low initial sealing temperature and firmly sealed temperature, to met very high speed auto packing machine, with High C.O.F. It is an co-extruded polypropylene film, one side treated with Corona, and other side engineered to have low SIT, Broad Sealing Range and High hot tack strength. It has high gloss, good optics, good printability, high heat resistance on untreated side. It is also good machinability, suitable for printing and lamination with other materials. And could met high seed FFS machines with excellent seal performance.

To laminate with other material for flexible packaging. Please tell the lamination purpose, the dry lamination, non-solvent lamination or PP extrusion lamination to get right option.

Key Feature:

-Very LOW SIT.

-Excellent Hermiticity.

-With High C.O.F for very high speed FFS machine.

-Most used in laminating.

APPLICATION:

Snack and biscuit packaging, stationery, confectionery, dry food.
