摘要： The plastic bag may include flexible thermoplastic sidewalls that have a pattern imparted onto them. The wrinkle pattern may be a plurality of linear ribs formed into the sidewall that may be arranged adjacent and parallel to one another. To impart the pattern to the sidewall, a thermoplastic web used to make the sidewall may be directed between a first cylindrical roller and a second cylindrical roller, each of which may have a plurality of spaced ridges extending about their peripheries. When the web is directed between the first and second rollers, the meshing of the ridges may form ribs into the web.

摘要： The bag may include first and second sidewalls joined along a first side edge, a second side edge and a bottom edge. The sidewalls may be un-joined along their top edges to form an opening. When the bag is placed in a trash receptacle, the top edges may be folded over the rim of the receptacle. To assist with securing the bag to the receptacle, the bag may include an elongated elastic strap of elastic material attached by a first end to an attachment point proximate the first sidewall and by a second end to an attachment point proximate the second sidewall. The strap length and attachment point locations are selected so that, when the strap is in a relaxed state, the strap may not extend to the side edge. The strap may be stretched commensurate with the side edge when folding the top edges about the receptacle rim.
摘要翻译：袋可以包括沿着第一侧边缘，第二侧边缘和底边缘接合的第一和第二侧壁。侧壁可以沿着它们的顶部边缘而不连接以形成开口。当袋子放置在垃圾桶中时，顶部边缘可以折叠在容器的边缘上。为了帮助将袋固定到容器，袋可以包括弹性材料的细长弹性带，其由第一端附接到靠近第一侧壁的附接点，并且第二端附接到靠近第二侧壁的附接点。选择带长度和附着点位置，使得当带处于松弛状态时，带可能不延伸到侧边缘。当将顶部边缘围绕容器边缘折叠时，带可以与侧边缘相当地拉伸。

摘要： Provided is a plastic bag including a live elastic strip that, in the elastic strip's normal condition, contracts thereby constricting an opening of the bag to assist in retaining the bag to an object. The elastic strip includes a first region that is continuously attached to a sidewall of the bag between a first side edge and a second side edge of the bag and a second region that remains unattached to the sidewall. The attached region does not contract but instead forces the portion of the sidewall to which it is attached to pucker into a serpentine path. The unattached region does contract causing the portion of the sidewall to which it is adjacent to bunch together. Also provided is a method for manufacturing a plastic bag that involves stretching a live elastic tape and continuously attaching a region of the stretched tape to a web of plastic material.
摘要翻译：提供了一种塑料袋，其包括活性弹性带，其在弹性带的正常状态下收缩，从而收缩袋的开口以帮助将袋保持在物体上。弹性带包括在袋的第一侧边缘和第二侧边缘之间连续地附接到袋的侧壁的第一区域和保持未连接到侧壁的第二区域。附着区域不收缩，而是将其附着到其侧壁的侧壁的部分压向蛇形路径。未附着的区域确实收缩，使得与其相邻的侧壁的部分聚集在一起。还提供了一种用于制造塑料袋的方法，该方法涉及拉伸带状弹性带并将拉伸的带的区域连续地附着到塑料材料的卷材上。

摘要： A flat mass-produced bag, preferably of plastic, of a rectangular shape made of two layers and having a mouth at one side adapted to be closed by draw strings which are slidable in hems formed adjacent to the mouth by folding over the free ends of both layers and securing them to the layers. The draw strings have a length greater than the width of the bag and the ends of each pair of corresponding strings are knotted together outside of each lateral side of the bag. When the two knotted pairs of strings are pulled in opposite directions, the mouth of the bag will be drawn closed toward its center.

摘要： The present invention is directed to a drawstring bag comprising a first panel and a second panel. The first panel and the second panel are joined along a first side, a bottom, and a second side. The first panel and the second panel thereby define an upper opening of the bag. The drawstring bag may further comprise a first pair of drawstrings disposed within a first hem along the upper opening of the bag in the first panel and a second pair of drawstrings disposed within a second hem along the upper opening of the bag in the second panel. The first pair of drawstrings may comprise a shorter elastic drawstring and a longer inelastic drawstring.

摘要： Methods for inserting a folded film into another folded film include combining the films without unfolding or folding either of the folded films. In particular, one or more implementations of a method of combining folded films involves directing a first folded film in a first direction and separating first and second halves of the first folded film. The method also involves directing a second folded film in a second direction generally perpendicular to the first direction. Additionally, the method involves inserting the second folded film between the first and second halves of the first folded film. Furthermore, the method involves redirecting the second folded film into the first direction while between the first and second halves of the first folded film.
