That plastic liner in a bottle cap
Fan of fizzy drinks? So are we! Its sparkling taste is matchless, and how great it is when we don’t only get the taste but also could win a free prize or get some reward codes? Not many people know this, but we might find any of these inside each of these bottle’s plastic liners. But are these liners there only with the purpose to surprise us?
Believe it or not, the prizing and rewards are only secondary functions of these liners. The liner inside of the lid serves as a sealing that guarantees to keep the carbon dioxide inside and keep the drink fizzy – its most important feature. Without these, we would be drinking a flat drink, taking all the fun of fizzy drinks away.
