Method for producing packaged goods, and packaged goods

Abstract

A method for producing packaged goods in which hermetic sealing performance is enhanced furthermore at the sealed end. The method for producing packaged goods comprises a filling step (St3) for filling a tubular film with a content; a squeezing step (St4) for squeezing the tubular film filled with the content to form flat portions where the content does not exist at predetermined intervals in the longitudinal direction of the tubular film; a collecting step (St5) for collecting the nonexisting portions in the direction traversing the flat surface; a tape member supplying step (St6) for applying a tape member, which is long in the traversing direction and has a heat shrinkage rate larger in the longitudinal direction than that in the width direction on the nonexisting portions, such that the collected nonexisting portions or the nonexisting portions to be collected are held in between; and a first sealing step (St7) for forming a sealed part in the nonexisting portions by sealing the nonexisting portions on which the tape member is applied in the traversing direction together with the tape member.

Description

technical field [0001] The present invention relates to a package manufacturing method and a package. In particular, it relates to a packaging body in which the compressive strength of a sealing portion is enhanced, a method for manufacturing the packaging body, and the packaging body. Background technique [0002] The known sealing method of sealing the cylindrical film filled with contents such as sausages and cheese sticks to obtain each package is a method of tying the end of the cylindrical film with a metal wire clip, that is, using a mould. A method of flattening a straight line of length circularly. However, in the method of tying with metal clips, it is inconvenient to use a metal detector to detect the metal clips in product inspection for checking whether metal foreign matter is mixed into the contents. In addition, when only metal wire clips are used for ligation, since unclean air penetrates between the converged and folded membranes, it is necessary to seal t...

AI Technical Summary

Problems solved by technology

However, since the surface of the converged cylindrical film is uneven, the uneven surface and the reinforcing belt cannot be uniformly adhered to, and although it can reliably seal and have the effect of supplementing the thickness, the effect of suppressing pores is small.
