Polystyrene (EPS) tray stacking
PROBLEM
- Handling of polystyrene containers after forming and removal of waste can result in the containers when stacked falling over due to static charges preventing the containers from stacking.
- In addition, handling the stacked containers for packing will result in the box size requiring additional dimensions increasing volumetric weight for transport.
- Handling of the waste material will result in operators receiving stack shocks, which can cause health and safety concerns.
SOLUTION
- Applying opposite polarity static charge to the top and bottom of the containers allows the containers to sit and stack properly.
- As the containers naturally attract to each other, picking up the stack of containers is made much easier, while allowing the box size to be reduced in height.
- Using a Meech IPS bar to control charges on the rewinding waste, prevents operator shocks when handling the rewound material.
