A daunting challenge confronting the big bag industry was the difficulty in manufacturing High Coefficient Of Friction (COF) anti-skid bags in matt option owing to the inherent properties of the ordinary OPP film.
A high COF is imperative for stacking big bags on to the pallets. Bags made from ordinary matt finish oriented polypropylene (OPP) film cannot be stacked as they skid during palletization. Thus there has been a burgeoning demand from the global clientele for big bags in Matt finish option. Big bags’, as the name suggests are rather heavy duty packages used for bulk-packing items like building materials, flour, rice and pet food among several others. This Low SIT High Seal Strength Matt Bi-axially Orientated Polypropylene Film engineered by the Packaging Film Business vertical of Uflex offers a number of positives like high haze > 75%; Low Seal Initiation Temperature (SIT) - 108 degrees C; low gloss on matt side; excellent matt dispersion; good contact transparency and excellent homogeneity. The film also exhibits high Hot-Tack strength and imparts paper like matt look to the bag significantly enhancing its aesthetics. This special film used for manufacturing big bags allows good stacking and sealing for pinch bottom.
