Webb Bottom Pinch Top (SSWBPT)
This style bag is gusseted with a square pasted bottom (like SOS) and pre-applied thermoplastic adhesive at the top (like PBOM). As the description implies, this style bag incorporates the good palletizing shape of the SOS style and the easy closing feature of the pinch bag. Though this style bag is more expensive than pinch it competes by offering more bags per truckable pallet with pallet shapes that can stack three high in a warehouse. This will reduce breakage in the warehouse and during truck loading. In evaluating the webb bag, it is important to remember that the cost of packaging includes more than the cost of the container.
This special style bag often provides a means of making an effective pallet load pattern and a means of developing an effective truck-loading pattern when other bag styles would not do.
