Abstract: Tearing, blistering, delamination and other defects in deep drawn plastic laminated paperboard containers are eliminated by adding controlled amounts of warmed moisture to the paperboard immediately prior to forming thereof. Water is heated to a desired temperature and is applied by in-line processing equipment to the unlaminated side of the paperboard which functions to both soften and paperboard and preheat the laminate. By heating both the male and female parts of a die press employed for forming the preheated, softened laminate into the container, preheating the laminate using warm water prior to forming and, continuously controlling the moisture added to the paperboard, the degree of stress imposed on the plastic layer of the laminate and the resulting defects in the formed container are significantly reduced.

Abstract: An improved easy opening pinch bottom or gusset bag is provided. The bag includes opposed front and back panels and opposed pairs of front and rear gusset panels foldably connected to one another. The rear gusset panels and the rear panel are of a sufficient dimension to fold over the front panel to close the bag. A tear strip is secured to the front panel at a location to be overlapped by the rear gusset panels and the rear panel when the bag is closed. The portions of the rear gusset panels and the rear panel that will lie adjacent the tear strip in the closed condition of the bag are provided with short perforation lines to facilitate the initial advancement of the tear strip through the rear gusset panels and the rear panel. These perforation lines extend only a short distance so that the overall strength of the bag is not adversely affected.
Abstract translation: 提供了一种改进的容易打开的夹紧底部或角撑板袋。 该袋包括相对的前后面板和相对的可折叠地连接的相对的前后角撑板面对。 后部角撑板和后面板具有足够的尺寸以折叠在前面板上以关闭袋。 当袋子关闭时,撕裂条被固定到前面板上的与后部角撑板和后面板重叠的位置。 在袋子的关闭状态下,靠近撕裂带的后部角撑板和后板的部分设置有短的穿孔线,以便于撕裂带通过后部角撑板和后面板的初始前进。 这些穿孔线仅延伸很短的距离,使得袋的整体强度不受不利影响。
