    • Method and apparatus for making a plastic bag or pouch wherein a plastic web is moved in a longitudinal direction and a tape made from an elongated plastic film is fed to the web. The tape is made of a pair of elongated attachment lanes of complementary fastening elements sealed to the film to function as attachable-detachable closures. The lanes extend parallel and are spaced apart. A perforation line is formed in the film between lanes, and a flange is defined on one side of only one of said lanes. The lanes are separated and pairs of lengths are cut off said lanes. The pairs of cut off lengths are sealed on a diagonal to the moving web in different directions to form V-shaped closures with the lane having the flange on one side thereof sealed to the web by the flange only. Bags are formed from the moving web. An intermediate product is described consisting of a narrow substrate having V-shaped closures spaced longitudinally for placement on a moving web in a bag making machine.
    • 用于制造塑料袋或袋的方法和装置,其中塑料网沿纵向移动,并且由细长的塑料膜制成的带被馈送到网。 胶带由一对细长的连接通道,其互补的紧固元件被密封到胶片以用作可附接的可拆卸的封闭件。 车道平行延伸并间隔开。 在车道之间的膜中形成穿孔线,并且在仅一条所述车道的一侧上限定凸缘。 车道被分离,并且在所述车道上切断成对的长度。 这些切断长度在不同方向上与移动腹板的对角线密封,以形成V形闭合件,其一侧的凸缘的一侧通过凸缘仅与腹板密封。 袋子由移动的网形成。 描述了一种中间产品,其包括具有纵向间隔开的V形封闭件的窄基板,以便放置在制袋机中的移动幅材上。

    • The invention relates to a shrink film packaging method by which articles intended for shipment by common carrier or to be sent through the mail may be wrapped so as to be protected from the usual and normal effects of handling. Articles to be wrapped are loaded onto a cardboard or plastic tray which is placed between the folds of two layers of material. The inner layer of material surrounding the tray and articles thereon is a special cushioning material which comprises closely spaced air bubbles formed by two sheets of polyethylene with air pockets formed therebetween. The outer layer of material is a shrink film and a sealer is utilized to form sealed edges around the tray and articles to form a package. The excess wrapping material is trimmed simultaneously as it is being sealed and the package is directed to a heat tunnel where the heat causes shrinkage of the outer shrink film which in turn causes the air in at least some of the bubbles of the inner material to be compressed to a pressure greater than atmospheric pressure.
    • 本发明涉及一种收缩膜包装方法,通过该收缩膜包装方法可以包装用于由普通承运人运送或通过邮寄发送的物品,以便保护其免受正常和正常处理的影响。 待包装的物品被装载在放置在两层材料的褶皱之间的纸板或塑料托盘上。 围绕托盘和物品的材料的内层是特殊的缓冲材料,其包括由两片聚乙烯形成的紧密间隔的气泡,其间形成有气泡。 外层的材料是收缩膜,并且密封剂用于围绕托盘和制品形成密封边缘以形成包装。 多余的包装材料在被密封的同时被修剪,并且包装被引导到热通道,其中热量导致外部收缩膜的收缩,这又导致内部材料的至少一些气泡中的空气为 压缩至大于大气压的压力。
