Free from harmful substances such as TCA and TBA that affect flavor, PVDC coextruded film can effectively prevent cork taint and spoilage, stabilizing the quality of wine throughout the entire storage and maturation process. Suitable for wide application with aluminum screw caps, it relies on PVDC core barrier technology to significantly extend the shelf life of beverages and fully protect the original flavor of wine.
With its outstanding comprehensive performance, PVDC functional barrier film is an excellent choice for high-end wine sealing and packaging.
