We supply standard and custom designs. We manufacture plastic cutting knives and blades for many plastic industries including fresh and dry food packaging, medical packaging, polyethylene plastic bag manufacturing, film converting, plastic vinyl and foil converters and many others. Some of our packaging knife applications include perforating, guillotine cutting, rewinding, cut off, cross cut, horizontal and vertical cut and other packaging cutting applications. Our plastic cutting knives and industrial plastic blades are in straight, circular, pointed tip, toothed, serrated, scalloped and many other blades by shapes.

Toothed Blades for Vertical Form Fill Sealing (VFFS) Machines, a core offering from Yafei Knives, are specialized industrial blades designed to streamline the packaging process in VFFS systems—one of the most widely used machines in the packaging industry. These blades combine two critical functions: cutting finished packages from continuous film rolls and creating secure, airtight seals along package edges. The toothed design of the blades ensures that seals are strong and consistent, preventing product spoilage (especially for perishables) while enabling clean, efficient cutting. Unlike generic VFFS blades that often struggle with seal integrity or uneven cutting, Yafei’s toothed blades are engineered to work in harmony with VFFS machine mechanics, delivering reliable performance for a wide range of packaging applications. Whether used for food, medical, or consumer goods packaging, these blades are essential for optimizing VFFS production lines.
The most notable feature of these blades is their ability to perform both sealing and cutting in a single, seamless step—a critical advantage for VFFS machines, which rely on speed and efficiency. The toothed edges of the blades apply uniform pressure to the packaging film, melting and bonding film layers to create airtight, leakproof seals. Simultaneously, the sharpened tooth tips cut through the sealed film to separate individual packages from the continuous roll. This integration eliminates the need for separate sealing and cutting equipment, reducing production time and minimizing the risk of misalignment (which can lead to poor seals or uneven package sizes).
VFFS machines often use heat to seal packaging films (e.g., polyethylene, polypropylene), meaning blades must withstand repeated exposure to high temperatures without warping, dulling, or losing their sealing capabilities. Yafei’s Toothed Blades for VFFS Machines are crafted from heat-resistant, hardened tool steel (reinforced with carbide in high-wear areas), ensuring they maintain their shape and performance even in high-temperature environments. This resistance to heat damage extends blade life and prevents costly downtime caused by blade failure.
Packaging facilities use a wide range of film materials, from thin, flexible films (for snacks) to thicker, durable films (for frozen foods or medical devices). These toothed blades are designed to handle all common VFFS film types, adjusting to film thickness and composition to maintain seal integrity and clean cuts. The toothed design also provides enhanced grip on slippery films, preventing slippage during the seal-and-cut process— a common issue with smooth-edged blades.
The food packaging sector is the primary user of these blades, as VFFS machines are widely used to package snacks (e.g., chips, cookies), frozen foods (e.g., vegetables, meats), fresh produce (e.g., berries, greens), and dry goods (e.g., rice, pasta). The blades’ airtight sealing capabilities ensure that food products remain fresh, free from contamination, and extend their shelf life. The clean cutting also ensures that packages have a professional appearance, enhancing brand appeal.
In medical and pharmaceutical packaging, sterility and product protection are paramount. Toothed Blades for VFFS Machines are used to package medical devices (e.g., syringes, bandages), pharmaceuticals (e.g., pills, powders), and sterile wipes. The blades’ ability to create secure, tamper-evident seals prevents contamination and ensures that products remain sterile until use. The heat-resistant material also meets industry standards for hygiene, as it is easy to clean and does not leach substances into packaging.
Beyond food and medical, these blades are used in packaging consumer goods (e.g., toiletries, household cleaners) and industrial products (e.g., small hardware, electronic components). For consumer goods, the blades ensure that packages are easy to open (thanks to clean cuts) while remaining secure during shipping. For industrial products, the durable seals protect items from dust, moisture, and damage during storage or transport.
Yafei offers customizable blade dimensions (length, tooth spacing, mounting holes) to fit most standard VFFS machine models (e.g., vertical form fill sealers from leading manufacturers). Provide your machine’s make and model, and the engineering team will design blades that match perfectly.
The toothed design applies uniform pressure across the film, ensuring that seals are consistent regardless of food type. For perishables (e.g., fresh produce), the airtight seal prevents oxidation; for frozen foods, it prevents freezer burn. The blades can also be adjusted (via machine settings) to accommodate thicker films used for frozen or heavy products.
Routine maintenance is simple: clean the blades regularly to remove film residue (which can affect seal quality) and sharpen them periodically (based on usage volume). The heat-resistant material means no special cooling or treatment is needed—just standard industrial blade maintenance practices.
Yes, the blades are compatible with most recyclable films (e.g., recycled polyethylene, compostable films). The toothed design ensures that these often more delicate films are sealed and cut without tearing or compromising the film’s structural integrity.
