bread bagging

HI

i have designed a semi automatic sliced bread packing m/c in which i use a contineous tube(Roll of Polypropylene tube) and individual covers are formed and bread is packed hot sealing the open end(not tying).

i have seen machine in which wickted covers are used for bagging unsliced bread loafs.i want to know is there any machine in which unwickted covers are used to pack sliced bread.please help me, since i am trying to designing a packing machine to pack sliced bread loaf using normal covers (bottom gusseted/side gusseted).if any of you come accross with such m/c please mail me the web site address directly to vijaymanae@yahoo.com

Thank you

Vijay
