These accessories are conical items that you can insert into the openings of bottles or other containers to seal them. You’ve probably at least once been in a situation to open a bottle of juice or wine, and then you couldn’t put the lid back on. However, there is a very practical solution when this happens, and that is to use a food safe silicone stopper. You can insert it into the opening of the container, so that it is sealed and that air, UV rays and other unfavorable factors cannot come into contact with food and lead to its spoilage and loss of sensory characteristics.

Remember that it is crucial to use food safe silicone stoppers if you want to ensure that the food below remains unchanged. Silicone is a perfect material for this purpose, because it is inert, which means that it does not enter into chemical reactions with food ingredients. If this happened, the food would begin to change its properties, which could be very dangerous to health. The use of silicone for such purposes avoids unfavorable situations and ensures optimal food quality and consumer safety.
