Pneumatic Round Corner Cutting Hole Puncher for Vertical Packaging Machines
Product Overview
The CRJ pneumatic Round corner cutting die is designed for use with vertical packaging machines. While the packaging bag is feeding, it simultaneously trims the side edge and cuts the rounded bag corner. The tool is made of Japanese-imported high-speed die steel and precision-machined using Japanese SEIBU slow-wire EDM to produce a uniform, sharp cutting edge. The reference hole size is 64×15mm. The edge-trimming width, corner radius, hole size, feed-through slot and overall dimensions can all be customized according to the actual packaging and machine conditions.
This product is intended for continuous production of plastic bags, paper packaging and flexible film packaging.
Key Advantages
Integrated Compound Cutting
This hole puncher combines side-edge trimming and rounded bag-corner cutting in one die. A single action trims the waste material and cuts the rounded corner, reducing separate processing and secondary finishing.
Precision Machining Using Japanese SEIBU Slow-Wire EDM
The complete tool set is made of high-hardness tool steel precision-machined using Japanese SEIBU slow-wire EDM. Its uniform, sharp cutting edges help reduce stringing, bag tearing and burrs during high-speed cutting, keeping the finished edges and corners neat.
Proprietary Patented Tooling Structure
CRJ has an R&D team, and this edge and corner cutting hole puncher is covered by multiple utility-model and design patents.
Suitable for 10–360μm Flexible Packaging Materials
Compatibility with PE, PP, OPP and aluminum-laminated film from 10–360μm. For thicker materials such as thick kraft paper and non-woven fabric, a custom tool configuration can be used, and sample cutting is recommended to confirm the result.
High-Speed Mass Production and Custom Configurations
The reference maximum speed is 180 cycles/min and has been verified through a 24-hour uninterrupted mass-production test at a leading-brand factory. The hole size, edge-trimming width, rounded bag corner, feed-through slot and overall dimensions can all be customized. Actual production speed depends on the material, thickness, air supply and machine synchronization.

Trial Operation and Routine Maintenance
After installation, first check the tool alignment, cylinder movement, guide condition, feed direction and cutting position at low speed.
Perform a small trial cut using the actual packaging material and confirm that the trimmed edge, rounded corner and packaging bag surface meet the requirements.
Increase the speed gradually while monitoring air-supply stability, film-feed synchronization and continuous cutting performance.
If burrs or film tearing occur, check in sequence whether the air pressure is insufficient or unstable, whether the cutting edge is worn or dull, whether the film feed is synchronized and whether the guide is misaligned.
Stop the machine and release the air pressure before adjusting, cleaning or inspecting the tool.

Frequently Asked Questions
Is this die compatible with all vertical packaging bag-making machines?
It can be adapted to most vertical packaging bag-making machines. Because the available installation space and mounting dimensions differ between machines, providing machine photos and installation dimensions before quotation is recommended for confirmation.
Can the rounded bag corner and edge-trimming width be customized?
Yes. The hole size, edge-trimming width, corner radius, feed-through slot and overall dimensions can all be customized according to actual requirements.
What is the minimum order quantity?
The minimum order quantity is 1 set.
What may cause burrs or film tearing during cutting?
Common causes include insufficient or unstable air pressure, a worn or dull cutting edge, unsynchronized film feeding or guide misalignment. Contact the engineering team for assistance with adjustment or to confirm whether tool regrinding is required.

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.
It is used to punch V-shaped easy-tear notches into plastic packaging bags/pouches and is compatible with various bag types and notch positioning requirements.
It utilizes a Japanese wire EDM machine with a rounded cutting edge, an imported high-speed steel punch, and an Airtac cylinder. The resulting notch is smooth, burr-free, and precisely aligned, ensuring smooth tearing without deviation. The notch size, depth, direction, and installation method can all be customized.
