One of the common methods to improve the sealing of the bottle or glass lid is to put a gasket inside the lid.
The washer has multiple functions:
Prevent bottle or glass leakage
Protecting the product against the penetration of oxygen and moisture and increasing the shelf life of the product
Foam washers are produced from foam rolls produced by Ako company and are produced as a single layer of light polyethylene (LDPE) and are used for the pharmaceutical industry in order to improve the sealing between the cap and the bottle.
The foams produced by Ako company have the ability to contact with pharmaceutical and food substances and are in accordance with the guidelines of the European Union, the national standards of Iran and the requirements of the FDA.
