Quad-seal foil gusseted bags WITHOUT a one-way gas valve. We use this bag to hold up to 15 kilos (33 lbs) of vacuum-packed green (unroasted) coffee. Approximate Size: W: 14" (355 mm), G: 3-1/4" (85 mm), H: 28" (710 mm). 6.4 mill of thickness.  These bags feature a four-corner seal design giving the side-gussets a reinforced structure, allowing the bag to hold its shape and stand better. These are the bags we use to vacuum-pack green coffee at origin. They work very well with our LMV-6010T vacuum sealer. Sales are only by the case; each case has 300 bags.
