Pinch Bottom Open Mouth Bag

This style bag is gusseted with a fold over pasted closure on the bottom and a pre-applied thermoplastic adhesive at the top for the customer to reactivate in closing. Its characteristics are:

• This style bag provides a very sift proof closure, and can employ a variety of barrier plies.
• This bag can be packed and closed on automated equipment, which can be operated and maintained by unskilled labor.
• This bag can have an airtight seal on both ends. This style offers a print area on the ends of the bag for product identification while the bags are lying flat.
• The ends of this style bag will remain pointed when the bag is filled.

This style is limited in practical thickness (gusset size) to a maximum of 6 1/2". Pinch bottom bags are generally used to package more expensive or sensitive products than Sewn Open Mouth is. Recently, pinch bags have begun to replace sewn bags in pet food, fertilizer and flour.
