TH4537B - Applications of a production line for packaging film packaging - Google Patents

Abstract

Methods and finishers for attaching narrow and continuous interlocking strips of re-encapsulated material to continuous strips of film material in the line of production to the machine. Completed forming, packing and sealing along the level to prepare the re-wrapped packaging. The fixing material is firmly fixed within the longitudinal fold line in continuous sheets of wrapping film material. And then the continuous sheet will continue to move directly into the forming machine. packing a tight seal In which the continuous sheet is aligned horizontally and the product is placed on the continuous sheet and the continuous sheet is wrapped upward around the two sides of the product to bring the edge in. come together to form the seal that is longitudinally And later the end of the product wrap will be sealed by a device for a tight sealing of the crossbar. and the end of the product wrap is cut from the continuous sheet. to separate the wrapped product Get out of the packaging that came before and after.
