Premium 60" x 180 yd secondary release liner with dual-sided silicone coating for precision die-cutting applications in industrial manufacturing.
The 3M™ Secondary Liner 4998 is a premium neutral-colored secondary release liner specifically engineered for selective die-cutting applications in industrial settings. This 58 lb polycoated kraft paper liner features dual-sided silicone release coating, with a matte side providing low release and a gloss side offering medium release characteristics. The liner measures 60 inches wide by 180 yards long with a thickness of 4.2 mils, making it ideal for laminating adhesive applications where precision die-cutting is required. The polycoated kraft construction provides excellent durability and stability during processing, while the dual-release coating system ensures optimal performance for converting and packaging operations across aerospace, electronics, medical, and general industrial applications.
This secondary liner is manufactured to strict industrial standards and is intended exclusively for industrial and occupational use by trained professionals and converters. The neutral color provides excellent aesthetic appeal while maintaining superior functional performance. The 4.2 mil thickness offers the perfect balance between flexibility and structural integrity, allowing for smooth processing through die-cutting equipment without tearing or delamination. The silicone release coating on both sides ensures consistent release properties throughout the entire roll, reducing waste and improving production efficiency.
The 3M Secondary Liner 4998 is widely used in aerospace manufacturing, electronics assembly, medical device production, military and government applications, packaging operations, and point-of-purchase displays. Its compatibility with laminating adhesives and superior release characteristics make it an essential component for manufacturers requiring high-precision die-cutting capabilities.
