This pouch is silver coloured on both sides.

These really practical bags are 12cm wide and 17cm to their zip lock closure. A gusset of 6cm max if used to full stretch will allow them to stand and have a great capacity. Both sides of this bag are silver to allow great label presentation and shelf display while not exposing the contents of your pouch to light which may instigate oxidation.. The top of the bag can be heat sealed with an impulse sealer if you have one, but is not competely necessary as the zip lock makes this an optional extra.
100gm capacity is to give an idea only, as it will depend greatly what you are filling the bag with.
