Abstract

The invention relates to the technical field of packaging bag manufacturing, and particularly discloses a processing method of a fresh frozen product packaging bag. The processing method comprises thefollowing steps that (a) thin films are unreeled; (b) a connecting belt is placed, wherein the connecting belt is placed on the lower thin film, the connecting belt is released through a placing unitwith reciprocating function when moving upwards, and the length of the connecting belt is larger than the width of the lower thin film; (c) the upper thin film and the lower thin film are attached toeach other, and specifically the upper thin film and the lower thin film entering a conveying roller are attached to each other; (d) transverse heat sealing is carried out on the packaging bag; (e) longitudinal heat sealing is carried out on the packaging bag; and (f) cold pressing and shaping are carried out on the packaging bag, and slitting and collection are carried out on the packaging bag.According to the scheme, by adopting the method, the connecting belt is added on the packaging bag, so that the problem that in the prior art, a fresh food packaging bag is worn in the transportationprocess is solved.

Description

technical field [0001] The invention relates to the field of packaging bag manufacturing technology, in particular to a processing method for fresh and frozen product packaging bags. Background technique [0002] When packaging fresh frozen products, in order to prolong the fresh-keeping time, four-side sealed bags with good airtightness and two horizontal seals and vertical seals are generally used (such as figure 1 ) for packaging. In order to facilitate the subsequent food loading when the four-side sealing bag is formed, generally only one of the horizontal seals and two vertical seals are sealed. After the food is loaded, the remaining horizontal seal is sealed. . [0003] After the fresh frozen food is packaged, it is necessary to put the packaged food packaging bag into the freezer for freezing and preservation. The frozen package is very hard as a whole, and because the meat used as fresh food is different in volume and shape The same, so that the shape and size of...
