Soft drink giant Coca Cola is testing a new plastic sleeve label for its Christmas launch. Coca Cola said the sleeve label is easier to recycle.
The shrink sleeve label that fully covers the bottle body can provide sufficient space for image and product information, which is more and more popular with manufacturers. However, for plastic recyclers, this kind of material is difficult to handle, because they cannot be sorted through the sorting device, which will cause a series of problems to the optical sorter, such as unable to float in the flotation tank, unable to air separation, etc.
But Coca Cola has developed a new sleeve label. The label is made of polyolefin mixture instead of modified PET, which can be separated from the pet sunk at the bottom and float in the flotation tank.
At present, bottles with full sleeve labels account for nearly 5% of plastic packaging recycling, and this proportion will continue to rise in the future. The full sleeve label will mislead the optical sorting equipment into color resin and easily mix with clean pet fragments sinking into the bottom of the sorting box. When recyclers use air separation technology for elutriation, they will also be mixed with lightweight mineral water bottles because of their similar characteristics.
Under real environmental conditions, Coca Cola pastes this polyolefin label on thousands of plastic bottles for testing, and sends these bottles to different PET recycling plants for recycling testing.
Satisfactory test results prompted Coca Cola to decide to use the new sleeve label in its disposable round plastic bottle specially designed for Christmas holiday.
