ABSTRACT:
According to the present invention, a water absorbing member is provided on a portion of the outer surface of a packing bag adjacent at least one sealed peripheral or circumferential side portion of the bag. By grasping this water absorbing portion when ripping or tearing open the bag, it is ensured that, even if the hands or gloves are wet, the water on the hands or the gloves in contact with the water absorbing member will move towards the water absorbing member and be absorbed thereby. This prevents a water film from existing between the hands or the gloves and the water absorbing member, so that a sufficient coefficient of friction exists therebetween to enable the packing bag to be ripped or torn open with sufficient tearing force. The present packing bag construction is particularly well suited for holding orthopedic casting materials and the like which must remain in a sealed closure until use and which are typically handled using hands or gloves which may be wet and slippery. In addition, the water absorbing member according to the present invention can be mounted on the surface of the packing bag by use of a simple construction such as by adhesion, so that the manufacturing steps for said packing bag are simple and easy and no complicated manufacturing apparatus is needed.
