High Quality Blades for Plastic Film Slitting

Plastic Film Slitting & Converting

Slitting is one of the most important material converting processes and refers to the slitting of a larger roll of plastic film wound on a reel into narrower strips. The process of slitting plastic film is most often performed in conjunction with unwinding processes, as it requires first unwinding the parent roll, slitting the plastic film material with industrial razor blades or slitting machine knives, and then rewinding it onto smaller spools. These processes are performed in parallel on slitter-rewinders - special cutting machines designed to convert plastic film. The slitting and winding of plastic film are the final converting steps in the industrial film production process.

Industrial razor blades with 3 holes. These blades also come in straight and rounded corners. The dimensions are 43x22 mm and the thickness of the blades varies from 0.10 mm to 0.40 mm depending on the cutting film material.

Try Sollex Zero Friction blades: Type Z for stretched thin films without additives. For film with additives, such as white pigments, try Type K blades. A basic TiN coating blade type T can be used in a wide selection of applications. 

PP with additives (for instance such as calcium carbonate which makes it similar to rubber) is really tough on the blade. Cutting such film requires extreme performance and durability. Sollex V quality such as 5V can work in cut extreme cases. Normal PP without additives should work with Sollex K and Z blades. C blades stay sharper even longer as they are self grinding. But the C quality is also bit fragile. Sollex X quality works if something between V and K is needed.

Sollex industrial razor blades for slitting plastic film, foil while manufacturing and converting - Hundreds of Sollex industrial slitting bladesMost Sollex industrial razor blades are delivered in a so-called partner pack. A package that is very suitable for industrial production. The razor blades lie on top of each other on two spears in a plastic package. The edges of the slitting blades do not come into contact with the packaging. For the user, it is easy to see how many razor blades are left because the lid on the partner pack is made of transparent plastic.
