<P>PROBLEM TO BE SOLVED: To reduce a poor seal in heat sealing as much as possible, which accompanies a foaming phenomenon of fluid to be sealed by a simple structure. <P>SOLUTION: This is a packaging apparatus for continuously making package bag bodies H having fluid enclosed between adjoining second heat seals Sb, Sb from a film F as follows: the second heat seals Sb are performed spaced apart in sequence in a direction crossing at a right angle a transferring direction (x) in respect to the film F, while fluid is fed continuously at a position preceding a position where the heat meltable film F is applied with first heat seals Sa along the transferring direction (x) and transferred while being formed into a cylindrical shape at its midway part. The second heat seal Sb is constituted of a pair of sealer members 4, 4 provided with butt portions 4a butting against butt portions 4a of the other sealer member 4 while the cylindrical film F is being held between them, and concurrently surfaces of the butt portions 4a of these sealer members 4, 4 are provided with a plurality of fine dimples 4d. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
