Slotted slitter blades, along with 3-hole blades, injector blades, and Gillette-type blades, are one type of industrial blade used in razor slitting processes in slitter rewinder machines when converting and slitting flexible materials such as paper, plastics, rubber, foils, films, and many others into narrow strips and then rewinding them into rolls. Slitting with slotted blades is ideal when cleanliness, consistency, and speed are crucial, especially for thin or delicate materials like films and foils.
Industrial slotted razor blades have dimensions of 57x19 mm, and are rectangular in form. In comparison to industrial blades with 3 holes, the slotted slitter razor blade's relatively robust design and single oblong slot in the middle allow it to convert and cut not only simple plastic films like PE or PP, but also thicker, abrasive materials with additives and impurities at a high speed, like recycled or calcium carbonate plastic films.
Slotted razor blades are often installed at a 45-degree angle in razor blade holders while slitting the moving web on a slitter rewinder machine.
The performance and choice of razor blade are often unaffected by the shape of the cutting edges, which can be either rounded or straight. Additionally, most of the blades are double-edged, which makes them adaptable for cutting or slitting in both directions. However, there are other non-standard industrial blade designs, including single-sided grinding (5SE) or having the sharp side on the short half of the blade (5SSE). The industrial blade has a slot 32x5.7mm that makes it simple to install or fix the blade in the slitter machine.
Additional coating of the cutting edge is used to extend blade life while reducing friction between the web material and the slitting blade. Coated cutting edges make them smoother and last longer than rough blades that are not coated.
Sollex industrial blades are available in the following materials and coatings:
We apply different coatings to the cutting edge to change the razor blade's cutting properties. We coat slotted blades to protect the razor blade from abrasion, reduce friction in the cut, and increase performance and durability. If you want to cut thin stretched film, our Z-coating fits while white plastic film (as an additive chalk) Slitter blades with K-coatings is a good choice. For really tough films (such as the addition of titanium), Sollex X coating is recommended. Slitter blades with Sollex X coating have the entire razor blade coated.
By using coated slotted razor blades, industries can achieve higher efficiency, lower maintenance costs, and improved product quality. These coatings allow for cleaner cuts, reduced material waste, and less frequent blade replacements, resulting in overall better production outcomes.
Sollex slotted slitter blades in solid tungsten carbide or ceramic are characterized by extreme performance and durability. An ordinary industrial blade installed in a machine that cuts plastic film usually lasts for 20 minutes. The slitter blades from Sollex made of solid ceramic (5C) or solid tungsten carbide (5V) can last for months. So the difference is huge. The solid ceramic (5C) is self-sharpening. This means that the more it wears, the sharper the slotted slitter blade set becomes. Industrial razor blades made of solid tungsten carbide (5V) instead retain the original grinding extremely long. Both razor blades in solid ceramic and solid tungsten carbide give you extreme performance and durability for tough films.
A basic slitter blade may last 20 minutes when cutting tough abrasive film with white additives. The same blade with a ceramic coated edge, such as Slitter Blade Ceramic Coating 5K, will last two weeks. If the same film contains a lot of ink and printing, the fully coated blade Slitter Blade Full Ceramic Coating 5X will perform much better. For a completely different, thin, stretched film at high speeds, the durability of the edge is not as important as the friction of the blade. In this case, the Slitter blade zero-friction 5Z offers such low friction and cutting performance that it will last for weeks. Solid tungsten carbide razor blades 5V are used for heavy duty applications, thick flexible materials, highly abrasive films, or plastic films with additives.

Slotted slitter blades are typically used in slitter rewinders where the web material needs to be continuously cut and wound, e.g. laminates, film, multilayer, aluminum and copper foil, paper, packaging, labels, tape, foam, textile and non-woven etc.
Industrial slitter razor blades are widely used across various industries due to their precision and efficiency in cutting materials.
Razor blades are most commonly used to slit various types of plastic films such as PE, PET, PA, EVA, PP, LDPE (Low-Density Polyethylene), HDPE (High-Density Polyethylene), BOPP (Bi-axially Oriented Polypropylene), stretch or shrink films. Agricultural and laminated films are especially challenging to cut, but slitter blades are designed to manage the complex layering while maintaining the quality of the edges. More about high-quality slitter blades for plastic film converting here.
Industrial blades are frequently employed to slit paper rolls into smaller sizes, maintaining high precision and minimal edge damage. This is crucial in the production of everything from consumer paper products to industrial-grade papers.
In textile manufacturing, slitter blades are used to cut non-woven materials like fabrics, cloth, and even hygienic products like Tyvek, diapers and medical textiles.
Converting adhesive materials into smaller strips is another common application of slotted slitter razor blades. With slitter blades offering high accuracy in cutting adhesive tapes, labels, and sticker materials without causing smudges or improper cuts.
Slitter blades are also essential for cutting thin metal foils used in various industrial applications like lithium ion battery production.
Slotted razor blades ensure the precise cutting of breathable films, hygiene plastic films, medical grade paper, DupontTM Tyvek® medical paper, aluminized film, foil, flexible polymer film, flow pack wrapper (HFFS), laminated film, and many more. Read more here.
Our slotted razor blades are specifically designed to meet the demands of industries such as plastic film manufacturing, flexible packaging, converting, printing. Whether you are dealing with delicate, thin materials like foils, BOPP or laminated films, or need a robust solution for textiles and non-wovens, Sollex ensures that our slotted slitter blades perform flawlessly.
Most Sollex 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 slotted Slitter 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.
