Product Description
AD*STAR® block bottom woven bags are made by extruding polypropylene resin into sheets, cutting the sheets into tapes, and weaving the tapes into the tubular fabric. The tubular fabric is then laminated, cut, and converted into a finished bag. The following information demonstrates the basic steps in manufacturing a poly woven block bottom bag.
Starlinger Company supplies integrated bag converting machinery to produce the woven valve bag from start to finish. Production steps include:
Tape Extrusion: High-strength tapes are produced by stretching after the resin extruding process.
Weaving: Tapes are weaved into tear-proof flat fabric in circular looms.
Coating: A thin layer of PP film is laminated to the woven fabric. Or additional BOPP film applied which can offer more eye-catching print and marketing effect.
Printing: Both flexo print and gravure print up to 8 colors, can be printed on the bag fabric.
Slitting: Top, bottom, and valve patches are pre-cut for the converting line.
Converting: Using Starlinger machines, sacks are assembled by forming the block bottom and applying patches and the valve using hot air sealing technology. No glue is used to seal the bag.
Baling: Bags are palletized and baled. Normally 8,000 bags can be baled in a single pallet.
