Pneumatic round hole punching molds for plastic bags are specialized punching equipment used in the production of plastic packaging bags. They rely on air to drive the punching action and are widely used in PE, PP, OPP and other film bags to punch various round holes such as hanging holes and venting holes. They are the preferred equipment for high-end mass production in the flexible packaging and bag making industries.
Scope of application
Applicable materials : PE/PP plastic bags, plastic films, paper, non-woven fabrics, and other flexible packaging materials.
Compatible equipment : Fully automatic bag making machine, semi-automatic bag making machine, film slitting machine, rewinding machine and other production line equipment.
Applicable processes : punching of various materials such as supermarket shopping bags, garment bags, packaging bags, non-woven bags, paper products, ventilation holes, and hanging holes.
Core Product Advantages
Ultra-high precision punching, zero defects in finished products : Imported custom-made mold steel combined with precision grinding process, the punching accuracy is controlled within ±0.001mm. The punched edges are smooth and flat, without burrs, wrinkles, or tears in the bag film, meeting high-end packaging quality standards and reducing defective product losses.
Genuine pneumatic components ensure stable high-speed operation : Equipped with original Airtac cylinders, providing balanced air pressure output. Continuous high-speed production is vibration-free, mold-free, and hole-position-accurate, ensuring strong consistency in long-term mass production.
Industrial-grade materials for durability : The thickened aluminum alloy mold base is lightweight and resistant to deformation; the imported cutting edge has excellent wear resistance, greatly reducing the frequency of mold replacement and lowering production line downtime costs.
High-efficiency mass production, suitable for bag making production lines : The round hole model can reach up to 280 times/minute, matching the production rhythm of high-speed bag making machines; pure pneumatic drive, no electricity required, suitable for various explosion-proof production environments in factories.
Universal and easy to install, with wide compatibility : The standard C-frame design is compatible with most bag making machines on the market, requiring no major modifications and can be put into production with simple debugging; gantry frame models can also be customized.
Strong non-standard customization capabilities, supporting OEM/ODM : We can customize the hole diameter, hole type (round hole, oval hole, square hole, butterfly hole, triangular hole, irregular multi-hole) and the length of the feed groove as needed. We can customize exclusive punching solutions according to the customer’s bag material and thickness, and support OEM & ODM customization.

Innovative Interchangeable Hole Puncher Revolutionizes Efficiency and Maintenance
In a groundbreaking advancement for the plastic packaging industry, our company proudly announces the release of our best-selling interchangeable punching machine. Designed to address key inefficiencies and high maintenance costs associated with traditional punching machines, this innovative product is already making waves in the market.
Efficiency and Versatility
One of the standout features of our interchangeable punching machine is its versatile punching needle. Unlike conventional machines with fixed hole types, our machine allows for the replacement of the punching needle with specific sizes and hole types. This flexibility greatly enhances the efficiency of the punching process, providing manufacturers with a wider range of options and significantly reducing downtime.
Cost-Effective Maintenance
Maintenance costs have long been a concern for businesses using punching machines, but our new model addresses this issue head-on. When the punching needle becomes dull from long-term use, instead of incurring high maintenance costs, users can simply pay a small fee for shipping and a new punching needle. This cost-effective solution ensures the machine continues to operate at peak performance without the financial burden of extensive repairs.
Ease of Replacement
Another notable advantage of our interchangeable punching machine is the ease of replacing the punching needle. The process is straightforward and user-friendly, eliminating the need for specialized technicians and minimizing production delays. This feature makes our machine not only efficient but also highly practical for everyday use.
Our interchangeable punching machine represents a significant leap forward in both efficiency and creativity. By addressing common pain points and providing a flexible, cost-effective solution, we are empowering businesses to optimize their production processes and reduce maintenance expenses.
