Food and Packaging
Before food enters the packaging stage, packaging materials such as plastic film, aluminum foil, composite film, and paper need to be divided and trimmed at high speed.
Application equipment: film slitting machine, rewinding machine, slitting machine.
Henglida's role: providing high-precision disc slitting blades, three hole blades, and shaver style film slitting blades.
Industry pain points and solutions: There are various types of food packaging films (such as multi-layer co extruded film, aluminum plated film), which are prone to dust, burrs, or film melting due to friction heat generation during high-speed cutting. Henglida uses ultra-fine grain hard alloy (tungsten steel) or high-grade stainless steel, which is polished with a mirror finish to effectively reduce cutting resistance, ensure clean and dust-free cutting edges, and avoid deformation of packaging edges due to heat.
Scenario overview: Fully automatic packaging of filling bag making sealing (VFFS/HFFS)
On the automated bagging production line for puffed foods, candies, nuts, flour, and other foods, sealing and cutting are performed synchronously.
Application equipment: vertical/horizontal fully automatic packaging machine, pillow packaging machine.
Henglida's role: providing serrated cutting knives, integrated sealing cutting knives, and flying knives.
Industry pain points and solutions: Packaging machines operate at high speeds and frequencies for cutting or punching, and often work in high-temperature environments for heating and sealing. Ordinary blades are prone to passivation or deformation due to thermal expansion, resulting in continuous cutting (continuous cutting). Henglida's tooth shaped cutting tools are made of special mold steel that is resistant to high temperatures and wear, and undergo precise temperature control and heat treatment. They can maintain sharp tooth tips and even and perfect tear lines (easy to tear edges) even under continuous high temperature and high-frequency punching.
Scenario overview: Cutting of corrugated cardboard boxes and outer packaging
The transportation and packaging of food cannot do without corrugated cardboard boxes and boards. The formation of cardboard boxes requires high-strength longitudinal and transverse cutting.
Application equipment: corrugated cardboard production line, computerized cross cutting machine, slot cutting machine.
Henglida's role: providing corrugated paper thin knives, cardboard box slot knives, and cross cutting flying knives.
Industry pain points and solutions: Corrugated paper contains high-density fibers and impurities, which cause significant wear on the blades. The tungsten steel thin knife produced by Henglida has extremely high hardness and wear resistance. When cutting paper, it does not flatten the corrugations, and the cut is smooth without falling off slag, greatly improving the compressive strength and aesthetics of the cardboard box.
Scenario Overview: Direct Processing and Cutting of Food
In the direct processing of meat products, fruits and vegetables, baked goods, etc., cutting tools are used for cutting, slicing, peeling or crushing raw materials.
Application equipment: Meat slicer, chopper, vegetable slicer, baking cutting line.
Henglida's role: providing stainless steel cutting and mixing knives, circular slicing knives, and special-shaped food processing knives.
Industry pain points and solutions: This scenario directly involves food and has strict requirements for rust prevention, corrosion resistance, and hygiene (non-toxic). Henglida adopts high-quality stainless steel that meets food grade safety standards (such as 4Cr13, 9Cr18Mo, etc.), and can be treated with special surface coatings (such as non stick coatings), which can resist the corrosion of food fruit acids and salts, and are easy to clean to prevent bacterial growth.
Henglida's core technological advantages in the food and packaging industry
Material Safety and Compliance: We provide specialized stainless steel and hard alloy materials that meet food hygiene standards, with strong corrosion resistance to ensure food production safety.
High frequency and long lifespan: In response to the high-frequency cutting requirements of packaging machines, which are hundreds of times per minute, the blades have extremely high temperature red hardness and fatigue resistance, reducing production line losses caused by downtime and tool changes.
High precision tooth profile machining: Using a five axis linkage CNC grinder to machine serrated knives and tearing line knives, the tooth profile is precise and free of micro burrs, ensuring a smooth tearing experience for packaging bags.
