Believe that many friends valve bag and adhesive bags don't know the difference between where, let me give you a brief introduction of the two plastic bags.    

        1. There is a glue adhesive bag: mouth, buy time with a small plastic paper cover, needs the sealing time to tear to plastic film exposed glue, can seal the bag, usually is a one-off. ( Of course you watch with a second open is not impossible)

2。 Valve bag: mouth has a sealing line, the line at the ends of the mouth, to its compression is closed, forcibly dragged away will be able to open the bag, not use glue, can repeat use.

        3. Dust jacket to the bag. < br />

simple terms since the glue bag with valve bag biggest difference with a repeated use, the equivalent of a one-off. < br />
