wicket poly bag :
A Wicket Bag is a pre-made, pre-cut bag that is specially made with an extra tab at the top.  The tab has two holes in it, called Wicket Holes.  The wicket holes allow the bags to be attached to one another with a U-shaped, metal wire called a wicket.  The holes also allow the bags to be mounted on a machine called a Wicket Bagger that can automatically open, fill and seal the bags.  In most cases, the wickets are also automatically trimmed off prior to the sealing operation
