Advanced cutting knives for film packaging
Film packaging processes such as classic flow-pack, shrink packaging, overwrap or sachet packaging require precisely selected cutting knives. Knife quality directly affects cut cleanliness, seal stability and the repeatability of the entire packing line, especially at high speeds.
GRAFS supplies knives for flow-pack packaging machines, intended both for simple low-speed machines and for advanced, very high-output lines operating continuously.
Applications of film packaging knives
Our solutions cover a wide range of horizontal packaging processes. Our knives work in machines carrying out flow-pack packaging, shrink film packaging, overwrap and various kinds of packaging with film folding and tucking. They are also used in lines packing horizontally fed bags and sachets.
These knives are used in the food, cosmetics and chemical industries and in packing technical and industrial products, where process stability and consistent packaging quality matter.
Knives for flow-pack and horizontal packaging machines
In this category we supply knives for cutting and sealing film, both transversely and longitudinally. The solutions offered include smooth knives, micro-serrated knives and knives designed for higher temperatures. Depending on the application, scissor knives, film slitters and knives for precise cutting of multipacks are also used.
Each knife is selected individually for a specific flow-pack machine model and line operating parameters.
Knives for shrink and overwrap packaging
We also supply knives for machines carrying out shrink and overwrap packaging. In these applications, cutting edge stability and wear resistance are key, especially with thicker films and high sealing temperatures.
A well-chosen knife affects the appearance of the packaging, product shelf life and safety during transport and storage.
Knives for sachets, bags and pouches
The growing use of stand-up pouches, bags and sachets requires precise cutting tools that ensure repeatable, clean edges. GRAFS supplies knives used at all stages of forming and closing packaging, including sealing, notching and slitting film.
These solutions are used both in packaging production and in lines packing finished products.
Materials, durability and special coatings
Depending on the application, we supply knives made of carefully selected steels, designed for intensive work in packing lines. For demanding processes, knives with increased wear resistance, anti-stick properties against film or special coatings that improve blade life can be used.
Material, hardness and geometry are always selected based on machine parameters, film type and operating speed.
