Product Description

1. Product Basic Information

• Product Name: High Speed Steel Serrated Blade for Packaging Film Slitting and Sealing Machine

• Material: High Speed Steel (HSS) - Selected high-purity HSS raw material, with excellent hardness, toughness and wear resistance, ensuring long-term stable cutting performance

• Core Application: Special for packaging film slitting and sealing machines, suitable for slitting, cutting and sealing of various packaging films

• Applicable Equipment: Automatic packaging film slitting machine, packaging film sealing machine, combined slitting and sealing equipment, and other related packaging machinery

• Tooth Profile: Precision serrated design - The serrated edge is processed by precision sharpening, with uniform tooth spacing, sharp cutting edge and strong anti-slip performance, avoiding film slipping during cutting

2. Core Product Advantages

• Superior Wear Resistance

  • Adopts high-quality HSS material, after strict heat treatment process (quenching and tempering), the hardness reaches HRC 62-65, which is 3-5 times more wear-resistant than ordinary carbon steel blades

  • The serrated edge is subjected to special surface treatment, which enhances the wear resistance and corrosion resistance, and avoids edge blunting caused by long-term contact with packaging film and moisture

• High Cutting Precision

  • Precision grinding technology is adopted, the blade surface is smooth and flat, the runout is controlled within 0.01mm, ensuring neat and burr-free cutting edges of packaging films, and avoiding film tearing or uneven cutting

  • The serrated tooth spacing is precisely calculated and processed, which can effectively reduce cutting resistance, improve cutting efficiency, and ensure consistent cutting effect even in high-speed operation of the machine

  • Excellent Stability & DurabilityThe HSS material has strong toughness and impact resistance, which can withstand the high-speed operation of packaging machines and avoid blade breakage or deformation caused by sudden load changes.

  • The overall structure of the blade is precision cast, with uniform material density, no internal defects, and long service life, which can reduce the frequency of blade replacement and save production costs for customers.

  •   Wide Compatibility & CustomizationIt is perfectly compatible with various models of automatic and semi-automatic packaging film slitting and sealing machines, and can be directly replaced without modifying the equipment, which is convenient and fast.

  •   We provide customized services according to customers' specific needs, including blade size, tooth spacing, tooth shape, thickness and other parameters, to meet the cutting requirements of different packaging film materials and equipment.

  •   Easy Installation & MaintenanceThe blade is designed with a standard interface, which is easy to install and disassemble, and can be operated by professional staff in a short time, reducing the downtime of the production line.

  •   The surface of the blade is treated with anti-rust and anti-adhesion, which is not easy to accumulate dust and debris, and only needs regular cleaning and inspection to maintain its good performance.

    4. Applicable Packaging Film Materials

  • Plastic film: PE, PP, PVC, PET, BOPP, CPP and other common packaging plastics

  • Composite film: Aluminum-plastic composite film, paper-plastic composite film, multi-layer composite packaging film

  • Other film materials: Non-woven fabric film, aluminum foil, packaging tape, label film, etc.

    5. Installation & Maintenance Notes

  • Before installation, check whether the blade surface is intact, and ensure that there is no burr, scratch or damage on the serrated edge.

  • When installing, align the blade with the equipment interface, tighten the fixing screws, and adjust the cutting gap to ensure that the cutting is smooth and free of jamming.

  • During use, avoid contact between the blade and hard objects (such as metal, stone) to prevent the edge from blunting or breaking.

  • After use, clean the blade surface with a soft cloth, apply anti-rust oil if it is not used for a long time, and store it in a dry and ventilated place.

  • When the blade edge becomes blunt, it can be sharpened by professional equipment, and it should be replaced in time if the wear is serious.

    6. Quality Assurance

  • All blades are manufactured in strict accordance with international industrial standards, and undergo strict quality inspection (hardness test, precision test, wear resistance test) before leaving the factory.

  • We provide a quality guarantee period of 3-6 months (depending on the use scenario), and will provide free replacement or repair services if there is any quality problem caused by the product itself.

  • We have a professional after-sales team to provide technical support and solutions for customers in a timely manner.
