The utility model discloses a contract the equipment on commodity or the grouping of commodities with the thermoplastic packaging material of plane formula. This equipment is including having two open -ended tunnel casings, and the its corresponding thermoplastic packaging material of commodity or grouping of commodities can get into in the tunnel casing and come out from the tunnel casing via the opening. Equipment still includes the conveyer, and it provides horizontally transportation plane in order to be used for the making motion of the its corresponding thermoplastic packaging material of commodity or grouping of commodities through the tunnel casing. Introduce heat energy in the tunnel casing. At least one open -ended opening cross section can increase and reduce. At least one device have the location in corresponding open area and at least the part arrange at least one valve in the tunnel casing, at least one valve for the increase with reduce corresponding open -ended opening cross section and can swing towards inward orientation with about the outer orientation of tunnel casing orientation about the tunnel casing around the axis with horizontally transportation plane angularity ground and preferred orientation perpendicularily.
