Grey opaque cross-linked shrink film is a durable packaging material known for its high tensile strength and puncture resistance. It is designed to shrink tightly around objects when heat is applied, providing a secure and protective wrap. The film's opacity effectively blocks existing product UPCs, making it ideal for scenarios where new UPC labels need to be applied. The cross-linking process enhances its durability and clarity, making it suitable for various industrial applications where both protection and visual appeal are important.
