Interchangeable Type R3-R12 Round Corner Cut Hole Puncher for Plastic Bag Film Quick Change

Product Overview

Constructed with an aerospace-grade aluminum alloy die base, imported Swedish ASP steel punch pins, and AirTAC cylinders, this rounded-corner cut punch unit is suitable for processing films ranging from 10 to 360μm in thickness and various flexible packaging materials. It offers a maximum operating speed of 200 cycles per minute, a machining precision of 0.001mm, and an estimated service life of 18 to 20 million cycles.

Customer Pain Points & solution

In the production of packaging for food, personal care products, and various types of flexible packaging, different bags often require different corner cut size. Configuring a complete set of equipment for each corner specification not only increases procurement and storage costs but also necessitates disassembly, alignment, and recalibration during product changeovers.

This changeable type puncher features an interchangeable, quick-release design, allowing a replaceable mold base to accommodate corner cut pins ranging from R3 to R12. The easy replacement process minimizes the need for machine reassembly, making it ideal for handling orders with diverse specifications and production runs requiring frequent changeovers.

Core Advantages

· Qucik and easy to change

Just 15 seconds to change; no need to align.

· Swedish ASP Wear-Resistant Punch Pin

The corner-rounding punching blade is made of imported Swedish ASP steel, featuring high hardness and excellent wear resistance.

· Save on costs and shipping fees.

In the future, you will only need to buy replacement punch pins, as the mould base can continue to be used; the pins are lightweight, low shipping costs.

· Multi-lane rounded corner cut solution

In addition to the single-unit puncher, we have movable and interchangeable corner cut puncher for multi-lane —such as 2/3/4 lane bags setups—compatible with high-speed multi-lane bag-making machine.

Quality control, ordering and after-sales service
