Quad-seal nylon gusseted bags WITHOUT a one-way gas valve. We use this bag to hold up to 30 kilos (66 lbs) of vacuum-packed green (unroasted) coffee. Approximate Size: W: 17" (430 mm), G: 6-1/4" (160 mm), H: 32-1/4" (820 mm). 6.6 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 200 bags.
