Boxes without handles are difficult to grasp. This is especially important for product that is extremely heavy. Examples of handhold devices. Plastic from one package may stick to another package. The added resistance of the plastic can create additional stress to the hands, arms, shoulders, and back.
Selectors often pull cases toward their body to gain better lifting advantage.
Forces required to pull the cases with these restrictions may actually be greater than the weight of the case. This will decrease the force needed to slide product toward the employee. Treat these cases as if they are heavy loads and provide additional head room and space on the side of stacks for access. Have suppliers wrap only the sides and tops of cases, leaving the cardboard bottom exposed to facilitate sliding. This repeated lifting can cause stress to the lower back.
