Interchangeable Butterfly Hole Punch machine for Bag Making Machine Pneumatic Quick Change punching perforation for PP PE PET Various Films
Interchangeable Butterfly Hole Punch machine for Bag Making Machine Pneumatic Quick Change punching perforation for PP PE PET Various Films
CRJ interchangeable pneumatic punch die is compatible with a wide range of bag-making machines. It allows for switching between various hole shapes—such as round holes, Euro-slots (airplane holes), butterfly holes, triangular holes, and R3–R12 corner rounding—by simply replacing the internal punch pin, without the need to change the entire hole puncher. Users can complete the punch pin replacement in approximately one minute after stopping the machine, thereby reducing the changeover time.
This puncher is suitable for PE, PP, PET, and various flexible packaging materials.with a maximum punching speed of 260 cuts/minute and a processing accuracy of 0.001mm. Customization of hole size, slot depth, hole shape and punching direction is supported, making it suitable for packaging production lines with multiple SKUs and frequent order changes.
Customer Pain Points&solution
Plastic bag and flexible packaging factories often handle multiple orders simultaneously, including supermarket hanging bags, fruit and vegetable bags, small commodity packaging, and stand-up pouches, requiring frequent switching between butterfly holes, airplane holes, round holes, triangular holes, and rounded-corner cutting. The traditional solution involves configuring a pneumatic hole puncher for each hole type, which easily leads to the following problems:
Multiple styles of orders require repeated purchases of the new puncher, increasing equipment investment;
Multiple punching machines installed side-by-side occupy production line and warehouse space;
Changing bag types requires disassembling the punching machine and realigning it, with changeover time potentially reaching ten minutes.
This punching machine features a robust aluminum alloy die holder and comes with a variety of interchangeable punching pins. Changing the hole pattern requires only swapping the punching pin itself, and additional punching pins can be purchased separately to accommodate new patterns. A single unit can handle more than five different hole patterns as well as corner-rounding operations.
Core Advantages
· Quick-change
After stopping the bag-making machine, remove the hole puncher and replace the punching pin. A skilled operator can complete the change in about one minute. After that, a test punch can be performed to resume production.
· A universal mold base supports various holes
An mold base can accommodate replacement pins with different sizes of round holes, airplane holes, butterfly holes, triangular holes, and rounded corners.
· Hole direction can be changed
For butterfly hole pins, air-plane hole pins, and triangular hole pins, the hole direction can be adjusted according to the requirements of the material moving direction.
· Saves space
One interchangeable punching device can replace multiple different hole shape punching machines; the replacement punch pin is small size and easy to store.
· Consumable parts can be replaced individually
As an independent component, the punching pin only needs to be replaced if it wears out, the mould base can be kept in use. Its pin’s lightweight design also reduces shipping costs.

What is the maximum thickness of the film that can be processed, and what is the reference accuracy?
It can process films with thicknesses from 10μm-360μm, and the processing accuracy is 0.001mm, depends on the material and test.
Can a large cylinder be added to a thick film punch?
Our engineers will adjust the cylinder size based on actual conditions.
Can special irregular holes and non-standard sizes be customized?
Yes.

Customization based on CAD drawings or physical samples
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.
