摘要:
The present invention relates to improvements for agricultural storage bags, more specifically agricultural storage bags having improved shock, tear and puncture resistance, and enhanced stretching properties. The agricultural storage bag has an embossed pattern of a plurality of embossed regions that are comprised of a plurality of linear embosses. Each embossed region is separated by a continuous unembossed region. Further disclosed is a method for forming the improved agricultural storage bags from a collapsed tube formed by a blown film extrusion process. More than one set of intermeshing rollers may be used to apply the embossed pattern to the improved agricultural storage bags. Once the storage bags are embossed, a folding operation may fold the bags into a plurality of annular folds so that the bags may be used with an agricultural bagging machine.
