The bar code on the side of the boxes is removed and placed on the component inside. If a component is rejected, it is returned to the vendor in the same box. The identical bar codes facilitate matching the component with its correct box. Because a box may have more than one bar code label, the labels are color-coded for ease of identification. Piggyback construction enables one label to be removed.
Perforations facilitate opening boxes, and serve as tamper indicators.
Color-coding differentiates the manufacturer's labels from other labels. In manufacturing operations static can be a serious problem. Static build up can affect productivity and product performance. Static can cause discomfort and even injury to workers. It can short out sensitive electronic components.
