Title:
PRODUCTION METHOD OF PLEATED LATERAL PILLOW PACKAGING BODY
Document Type and Number:
Japanese Patent JP3891861
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a production method of a pleated lateral pillow packaging body which is stably self-supporting with a tight package shape concealing its bottom face by a pleat hanging down around the peripheral edge of the bottom face when the packaging body is laterally pillow packaged, cut off and is turned by 90 degrees.
SOLUTION: In producing this pleated lateral pillow packaging body, a packaging material with a pleat which extends in a direction crossing at right angles relative to the direction where the packaging material continues and the inner faces of whose folded part are mutually adhered and fallen sideways is formed in a square tube shape by a former, and both end edges of the packaging material are heat sealed to be transported continuously as a tunnel shaped packaging tube. An item to be packed is sent into the packaging tube formed in the inside of the former to be positioned between the pleats by a transporting conveyer. Then at the downstream of the former, the packaging tube is two-strip heat sealed by a two-strip sealer between the items packaged, and is cut between the heat sealed two strips to be separated.
