Using less paper for same size bag,For example bag size(H320*W300*G150mm),the paper roll need is 850mm width,length need is 470mm |
Using more paper,For example bag size(H320*W300*G150mm),the paper roll need is 930mm width,length need is 470mm |
| Sealing method |
Heating sealing |
Glue sealing |
| Consumable items |
No Consumable |
glue |
| Firmness |
Sealing in two side by L shape,more strong |
Sealing in bottom by glue,easy broken |
