    • A bag made of a flexible packing material comprising a sheet of material having an inner face and an outer face and folded for the formation of a tube with an overlapping portion. In the overlapping portion, the packing material is sealed inner face to outer face by means of a lapseal. Along two side edge portions, the tube is welded inner face to outer face of the overlapping portion for obtaining a closed bag enclosing the packed product. The packing material provides a peel seal, when welded inner face to outer face and a strong seal when welded inner face to inner face. Seen relative to the bag, the packing material comprises an inner layer comprising polyethylene, and outer layer comprising a copolymer of polyethylene and polypropylene and a subjacent intermediate layer comprising polypropylene.

    • A dispensing package for a roll of seed tape consisting of a plasticized cardboard backing to which a transparent cover member is hermetically sealed to define a reel cavity. A reel for the seed tape is rotatably carried in the cavity, which includes a tangential outlet through which the tape can be dispensed. The reel consists of a flat circular cardboard member, having suitable printed indicia on one face for viewing through the transparent cover, and a plastic spool which cooperates with the cardboard member to carry the tape. Means are provided for locking the reel in a predetermined position to preclude its rotation due to hygroscopic expansion and contraction of the tape, and to thereby maintain the printed indicia in an upright position.
    • 一种用于一卷种子胶带的分配包,其由塑化的纸板背衬组成,透明盖部件被气密地密封到其上以限定卷轴腔。 用于种皮带的卷轴可旋转地承载在空腔中,该空腔包括切向出口,带可以通过该切口出口。 卷轴由一个扁平的圆形纸板构件组成,在一个面上具有合适的打印标记,用于通过透明盖观察,以及塑料卷轴,与纸板构件配合以承载带子。 提供了用于将卷轴锁定在预定位置以防止其由于吸湿性膨胀和收缩带旋转的装置,从而将打印标记保持在直立位置。
