Cups are coated in PLA (Polylactic acid), a plant-based plastic that comes from sustainable sources on both the board and the coating. Drawbacks Covered In Latest Cups Previously, PLA was primarily employed in the manufacture of plastic glasses for serving cold drinks. This is because PLA would disintegrate if it came into contact with a hot beverage. The most recent varieties have been thermally treated to make them safe for use with steaming hot beverages; this advancement has made the coating suitable for use with paper coffee cups.

Paper is almost always treated, coated, laminated, or impregnated with compounds such as waxes, resins, or lacquers to increase functional and protective features when used as primary packaging. The following are some of the many different types of paper used in food packaging: Kraft paper is a...
