What is Film Tape Yarn?
Film tape yarn is a type of yarn that originates from extruded polymer films, slit into narrow tapes. They are used in the textile industry as yarn (carpet backings, big bags, artificial grass,...) and for applications such as tear tape in flexible packaging, fishing nets, etc... Their production involves the cast extrusion of a polymer film, slitted by an array of blades and followed by a heating, drawing and cooling process to set the fiber into its final form.
Slitting Issues Caused by Film Tape Yarn
Film tape yarn slitting requires precision to ensure the integrity of the tapes and the quality of the final product. However, several issues may arise during this process that could compromise the functionality of the tapes.
Razor Blade Lifetime
Razor blades used in slitting film tape yarn can be compromised due to the abrasiveness of the material. High-strength polymers may lead to frequent blade changes, increased downtime, and higher operational costs. Selection of blades with appropriate materials and coatings can enhance durability and reduce the frequency of replacements.
Dust Particle Formation
The majority of film tape yarn is made out of mineral charged polymers, imposing abrasive wear on the razorblades. During slitting, (mineral) dust may form on the cutting edge of the blade. The built up disturbs the cutting process.
Razor Blades for Slitting Film Tape
For effective film tape slitting , it is mandatory to identify and utilize razor blades that can withstand this intensive continuous process while maintaining precision.
