    • A system is provided for mounting a flat, display item such as a photograph, on a surface such as the pages of an album, a book, a report, or any other substrate. The system includes a one-piece, transparent pocket folded to define an upper display surface and an opposed lower surface. The pocket is open along at least one side edge to permit insertion of the item between the opposed surfaces. A layer of adhesive material is provided over substantially the entire lower surface of the pocket for adhesively mounting the pocket to the surface. The adhesive material, preferably a thermoplastic, pressure sensitive, medium tack adhesive, is initially releasable but after a period of time, forms a permanent bond between the pocket and the surface.An album for displaying such flat, display items is further provided. The album includes a plurality of pages for mounting the display items and a plurality of these one-piece pockets.A method for manufacturing a plurality of these one-piece pockets is still further provided. The method comprises the steps of providing a continuous web of transparent material; applying a continuous line of adhesive material to the web; folding the web along upper and lower fold lines to form a continuous sleeve; sealing the sleeve along the continuous line of adhesive and laminating to one surface thereof a web of release paper which has been coated with a second adhesive; and cutting the laminated sleeve in predeterminated locations to form a plurality of the pockets.
    • 提供了一种系统,用于将诸如照片的平面显示项目安装在诸如专辑页面,书籍,报告或任何其他基板的表面上。 该系统包括折叠的单件透明袋,以限定上显示表面和相对的下表面。 口袋沿着至少一个侧边缘打开以允许物品在相对的表面之间插入。 在袋的基本上整个下表面上设置一层粘合剂材料,用于将袋粘合地安装到表面。 粘合剂材料,优选热塑性的,压敏的中等粘性粘合剂,最初是可释放的,但在一段时间之后,在凹穴和表面之间形成永久的粘合。 还提供了用于显示这种平面显示项目的专辑。 该专辑包括用于安装显示物品的多个页面和多个这些一体式的口袋。 还提供了一种用于制造多个这些一体式袋的方法。 该方法包括提供透明材料的连续纤维网的步骤; 将连续的粘合剂材料线施加到幅材上; 沿着上下折叠线折叠卷材以形成连续的套筒; 沿着连续的粘合剂线密封套筒,并将其涂覆有第二粘合剂的隔离纸的一个表面层压到其一个表面上; 以及在预定位置切割层压套筒以形成多个袋。
