Resin bottles are charged with static electricity during the molding and transfer processes. The labels are charged during roll transfer as well as by the separation from the release liner when they are affixed onto the bottles.
The repulsion and attraction between the charged bottle and label cause the label to shift from the proper position.
- It can prevent the release of defective products, but it cannot improve the yield rate of the product.
Countermeasures with static eliminators (ionizers)
An ionizer can reduce the waste of material costs and improve the yield rate.
Disposal cost due to defective labeling: $400/month x 12 months = $4,800/year
In addition, there are other resulting benefits of improved reliability.
