    • A pouch for holding liquids includes a pre-inserted straw within the pouch. A top end of the straw is exposed by removing a portion of the pouch. For manufacture, a web of flexible packaging material, suitable for forming a pouch or bag for storing liquids, is advanced forward in a pouch forming direction. A single straw of suitable length to fit within the confines of a resulting pouch is cut from a continuous length of straw material. The single straw is placed onto the web of packaging material in a location that will be on the inside surface of a single wall of the pouch and there it is secured in place preferably by a heat seal between one side of the straw and the inside surface of the pouch wall. The resulting pouch web material, having a plurality of straws positioned along its length provides a feedstock for forming pouches with pre-inserted straws when using a so called form and fill method of forming pouches or when making pre-made pouches. The pre-inserted straw is totally enclosed within the confines of each resultant pouch and therefore eliminates the need to be attached to the outside of the pouch or be inserted into the pouch through one of the walls of the pouch.
    • 用于保持液体的袋包括在袋内的预先插入的吸管。 通过去除一部分袋子来暴露吸管的顶端。 为了制造,适于形成用于储存液体的袋或袋的柔性包装材料的网沿袋形成方向前进。 从连续长度的秸秆材料中切割适合长度的单个秸秆,以适应所形成的小袋的范围内。 将单个吸管放置在包装材料的网状物上,该位置将位于袋的单个壁的内表面上,并且其优选地通过在吸管的一侧和内表面之间的热密封固定在适当位置 的袋壁。 所得到的袋状材料具有沿其长度定位的多个吸管,当使用所谓的形成袋子的填充方法或制备预制袋时,提供用于用预先插入的吸管形成袋的原料。 预插入的稻草完全封闭在每个所得袋的范围内,因此不需要附着到袋的外部或通过袋的一个壁插入袋中。
