Our liner is an additional "sealing layer" that is placed on the inside of the lid. It provides improved functionality and a better longer stability time for the product. While our material already has good oxygen barrier properties, adding the liner further protects the products inside the jars. It prevents leakage, provides an additional barrier e.g. against moisture loss, for flavors and active ingredients, reduces oxygen penetration and thus extends shelf life.
The liner is suitable for oil- and waterbased as well as for dry products.
Our liner is flexible and can be mechanically placed inside the lid. No adhesives or other additional glues are needed. It is fully biodegradable and free of microplastics and BPA (bisphenol A).
The thickness of the liner is 0.8 mm or 1.2 mm, depending on the size of the respective jar.
