While these lines are often thought to be ornamental, those found on on plastic cups are used to delimit the appropriate fill level for different types of alcohol. You will surely pay more attention now when you have one of these glasses in your hand.

What do the lines on the plastic cups mean?

The first line would be to pour a glass of alcohol (30ml), which you then add juice or soda to finish filling the glass.

The central line would be used to fill a portion of wine (150 ml).

The lines on the cups are really designed for practical considerations. If the lines correspond to certain measurements, it is purely by chance, according to Dart Container Corporation, a representative of the parent company of the cup brand, a flagship brand of this type of glass.

If this is a random detail, the stripes clearly distinguish the exact measurements of 30ml, 150ml and 350ml.

Can plastic utensils and cups be reused? An expert gives his opinion

Before you put away your disposable items after the party, consider giving everything from plastic spoons to plates a second chance.

Alexandra Davis spent a decade working as a plastics engineer for the world’s largest private thermoplastic producer. She then created Ryan and Alex Duo Life, a health and wellness site for couples.

“It gave me a glimpse into a world not shared by consumers,” Davis says of his former career. “And when it comes to the requirements for disposable and reusable plastics, you might be surprised to find that most countries actually follow the European Union FDA food contact policies,” she adds. .

So no matter where in the world these disposable cups come from, they are likely to be regulated by strict policies, regarding issues such as how plastic reacts to acids found in foods like apples, tomatoes and coffee. So every element of the little plastic knife in your cheese board needs to be sifted through, from the materials themselves to the additives used for color.

“Most plastic plates, cups and utensils can be reused. Especially when washed by hand, as higher dishwasher temperatures can reduce the life of the product “emphasizes the expert. She advises watching for signs of cracking, as those little cracks can harbor bacteria, but argues that you generally don’t have to worry about chemicals growing in your food.
