Punch for plastic bag applications is a toothed cutting tool designed to create repeatable holes in polyethylene, polypropylene, paper and packaging film. Diameter, tooth count, body length and tool steel grade can be customized to match the film and punching machine.

Toothed punch sizes and materials

Common diameters include 3, 5, 6, 8, 10, 12 and 15 mm, while other dimensions can be manufactured from a drawing or sample. Carbon steel is suitable for basic applications; HSS and carbide grades can provide higher wear resistance for demanding production. The best choice depends on film abrasiveness, production volume, machine alignment and maintenance practice.

How to specify a punch for plastic bag production

• Required hole diameter, shape and dimensional tolerance.
• Film material, thickness, number of layers and any reinforcement.
• Punch body length, shank diameter and mounting details.
• Desired tooth count, cutting direction and backing plate condition.
• Expected cycles per minute and target service life.

A complete specification prevents common problems such as incomplete cuts, film stretching, excessive burrs and rapid edge wear. For a complete pneumatic handle-hole unit, review the hand punch for plastic bags. For wicketed packaging, see the wicket punch.

Use and maintenance

Align the punch concentrically with its support opening and avoid side loading. Keep the edge free of adhesive and plastic residue. Replace or professionally resharpen the tool when holes become incomplete; changing the tooth profile during sharpening can damage film and reduce repeatability.

Frequently asked questions

Can the punch be made from carbide?

Yes, subject to dimensions and application. Carbide may improve wear resistance but requires careful handling because it is more brittle than steel.

Can you manufacture from a sample?

Yes. A drawing is preferred, but a sample can help identify dimensions and edge geometry for review.

What causes incomplete holes?

Typical causes include a dull edge, poor alignment, unsuitable support clearance, film movement or insufficient punching force.
