Making method:
Our bags are sewn with 3 - needle chain stitch to ensure seam integrity. Top constructions consist of snap band, flange top, ring top, soft cuffs or raw edge. Bottom removal bags are constructed with a raw top or soft cuff. Top and bottom removal bag bottoms have disc bottoms that are sewn using an overlock (surge) stitch or lock stitch. A wear strip or custom skirts is attached to the bottom portion of the bag to prevent premature wear from bag-to-bag and bag-to-cage abrasion.
