Bottle cap threading lubrication

Bottle cap threading lubrication
Every day, millions of people twist open plastic bottles without realizing the caps rely on tiny amounts of food-grade lubricant. During manufacturing, these lubricants are applied to the threads to prevent the caps from jamming on high-speed bottling lines that can fill over 1,000 bottles per minute. Without this lubrication, the friction would generate enough heat to deform the plastic threads. The same lubricants also ensure the caps can be opened smoothly by consumers without requiring excessive force.
