Why do they put that plastic blue disk in the lids of softdrink bottles?
Look inside the screwtop lids on softdrinks! Why are they there!
Answers:
That plastic blue disk is actually a food grade quality rubber. Coco-cola first started using them in 1987 when they started to move away from the glass bottles, do you remember when soda came in the short squat glass bottles with the metal screw lids? Those had a wax coating on the inside to keep the bottles pressurized, meaning to keep the carbonation in. Wax didn't work as well with the plastic lids and bottles that they have now, it was expensive and wasn't keeping the bottles sealed. Rubber was introduced and bam! We now have little blue rubber disks on the inside of our bottles.
they are actually softer than plastic and they seal the bottle so it is completely air tight
