The plastic wrap on dishwasher detergent capsules is a water-soluble film that encapsulates the concentrated detergent. It dissolves during the wash cycle, releasing the detergent into the dishwasher.
The purpose of the plastic wrap is to provide a convenient and pre-measured dose of detergent while also keeping the detergent dry and stable until it is needed. The water-soluble film is designed to dissolve quickly and completely in water, so there is no need to remove it before placing the detergent capsule in the dishwasher.
During the wash cycle, the water jets spray water onto the detergent capsule, causing the plastic wrap to dissolve. The detergent is then released into the dishwasher, where it mixes with the water and helps remove food particles, grease, and stains from the dishes.
It is important to note that not all dishwasher detergents come in capsule form with plastic wrap. There are various types of dishwasher detergents available, including powders, gels, and tablets, each with their own packaging and usage instructions. Be sure to follow the specific instructions provided by the manufacturer of the dishwasher detergent you are using.
