MAKING BOXES, CARTONS, ENVELOPES OR BAGS (incising, scoring, in general B26D 3/08; combined making and filling B65B)
NOTE
-
In this subclass, envelopes or bags are regarded as being essentially flexible containers, the final shape of which is determined by their contents.

In this subclass, the following expression is used with the meaning indicated:
- "boxes or cartons" includes bags formed similarly to cartons, trays with upstanding side-walls, barrels, tubes and cups, other than articles formed by winding.

In this subclass, it is desirable to add the indexing codes of B31B 2201/00 - B31B2241/00N

WARNING
-
The following IPC groups are not used in the CPC scheme. Subject matter covered by these groups is classified in the following CPC groups:
