Uflex’s big bags are used for bulk-packing items like building materials, flour, rice and pet food among several other products

A challenge confronting the large bag manufacture was the difficulty in manufacturing high coefficient of friction (COF) anti-sideslip bags in matt pick owing to the inherent properties of the ordinary oriented polypropylene (OPP) film. A high COF is imperative for stacking large bags on to the pallets. Bags made from ordinary matt cease OPP film cannot be stacked as they skid during palletization. Thus in that location has been a burgeoning need from the global clientele for large bags in matt finish option.

Immaculately engineered big numberless past the converting/packaging business concern vertical of Uflex are fabricated by combining high COF, low Seal Initiation Temperature (SIT), loftier seal forcefulness matt bi-axially OPP moving picture and high performance woven polypropylene (WPP) textile. This combination imparts high strength to the bags making them fit for heavy duty applications. The big bags fabricated of this special film have qualified the critical driblet tests as laid down by the ASTM standards.

This depression SIT high seal strength matt bi-axially OPP film engineered by the packaging motion picture business organisation vertical of Uflex offers a number of positives like loftier haze > 75%; low SIT – 108 degrees C; low gloss on matt side; splendid matt dispersion; good contact transparency and excellent homogeneity. The film also exhibits high hot-tack force and imparts paper like matt look to the bag significantly enhancing its aesthetics.

This special moving-picture show used for manufacturing big bags allows good stacking and sealing for pinch lesser. The pinch bottom is the process of pace-cut sealing at the lesser of the bags through hot air purging. The compression bottom option offers far superior sealing as compared to conventional methods like bottom fold taping and stitching. Above all, pinch bottom offers a leak-proof seal as opposed to ordinary sealing.

Equally y'all bring together us today from India and elsewhere, we have a favour to inquire.
