[Abstract] The present invention discloses a method for packaging articles using a packaging film web, wherein the packaging film web is provided with at least one tear line along the MD direction. The method includes the following steps: (a) In the MD direction, a tab is formed on the film at regular intervals. The tab is provided with a free end. The free end is connected to the opposite end of the tab through its free side, and the opposite end is connected to the film. The tongue is oriented on the film: at least one tear line is passed through both ends of the tongue at the axis of the MD; (b) is cut by cutting along an axis substantially transverse to the TD direction of the web, the axis being transverse The insertion tab is interposed between its ends, and the tab is not substantially severed on the axis, so that the tab can be extended from the leading edge of the tab; (c) one at step (b) The sheet produced is wound onto an article to form a tube body while making the cut edges of the sheet overlap each other, the free end of the tongue is located at the top of the overlapping area, and the overlapping area is located in the tube body. Outside, and the cut edge of the slice to a certain extent Overlap each other: the film tabs on the top surface overlap with the underlying film; (d) seal the film together in the overlap area with a sealing device, wherein the sealing device: (i) can be located at the overlapping portion The outside of the inner tear-line region strongly seals the overlap region, where the tear-line region is defined by the trim region of the overlap region (excluding the TD) and a pair of non-cut edges (parallel to the MD) parallel to the film. And each axis extends through the widest point of the side of the tongue so that the free end of the tongue is in an unsealed state or is sealed to the membrane with only very low strength; (e) the body of the tube The end portion is wrapped around the article and the end portion is sealed to form a sealed package around the article, and the free end of the tab can be pulled to tear along the tear line, thereby wrapping the package. Easily open. Film-wrapped packages made by the above method are also disclosed.
[Sovereign Items] 1. A method of packaging articles with a packaging film web having at least one tear line disposed along the MD. The method includes the following steps: (a) In the MD direction A regular interval forms a tongue on the film. The tongue has a free end. The free end is connected to one end of the tongue through its free side, and the end is connected to the film. The tongue is in the following manner. Orienting on the film: passing the axis of at least one tear line in the MD direction through the two ends of the tongue; (b) cutting the film web by substantially along an axis transverse to the TD direction of the film web. It is cut off, the axis passes through the tongue between the two ends of the tongue, and the tongue is not substantially severed on the axis, so that the tongue can be extended from the leading edge of the sheet; (c ) A sheet made in step (b) is wound around an item to form a tube while the edges of the sheet overlap so that the free ends of the tabs are on top of the overlapping area and the overlap The area is located on the outside of the tube and the thin slice At least in accordance with the following manner to a certain degree overlap each other: there is a space area completely in the overlap area, the space area is defined by the sides of the film, the first pair of axes (excluding TD outside) is defined, the axes are overlapping The edge of the sheet underneath the area and an axis extending parallel to the body of the tube and through the connecting end of the tongue; (d) Sealing the film together using sealing means in this overlapping area, wherein: (i) the tab area The outer side is substantially completely sealed, wherein the tongue region is defined by the edge of the overlap region and a second pair of axes (other than the MD) perpendicular to the first pair of axes, wherein the first pair of axes defines the spaced region, and the second Extend through the widest point of the respective free edge of the tongue for the axis, respectively; (ii) substantially seal the inside of the tongue region only in the region of the gap so that the free end of the tongue remains substantially unsealed to the membrane (e) winding the end of the tube around the article and sealing the end to form a sealed package around the article, and by pulling on the free end of the tab Tearing along the tear line, so that the package be easily opened.
