70×20mm Pneumatic Type Handle Hole Heat Sealing Cutting Die for Plastic Film
70×20mm Pneumatic Type Handle Hole Heat Sealing Cutting Die for Plastic Film
The 70×20mm pneumatic handle-hole heat sealing and cutting die is a bridge-type closed-frame die designed for automatic heat-sealing and cutting bag-making lines. Its pneumatic actuator drives a copper tool to heat-seal around the handle hole and cut the hole profile at one processing position. It is intended for production scenarios that require fewer separate sealing and cutting operations.
70×20mm Pneumatic Type Handle Hole Heat Sealing Cutting Die for Plastic Film
Product Overview and Customer Challenges
Conventional multi-step processing requires separate heat-sealing and cutting stations, increasing equipment space, alignment work and changeover setup. If heat, pneumatic motion or the bag-making machine cycle is not properly matched, incomplete sealing, hole misalignment, sticking at the cut or film damage may occur. CRJ integrates the heating and hole-cutting structure in one bridge-type die base so that bag design, material and installation position can be evaluated together.
Suitable customers: Packaging bag manufacturers that need heat-sealed handle holes in flat bags, T-shirt bags, biodegradable bags and other plastic packaging bags on automatic bag-making equipment.
Key Advantages
Simultaneous Handle-Hole Heat Sealing and Cutting
Heat-seals around the handle hole and cuts the 70×20mm profile at the same station, reducing the space, alignment and setup required for two separate dies.
Bridge-Type Closed-Frame Structure
The bridge-type closed die base supports film feeding, the tool, heating components and the pneumatic actuator. It can be configured around the confirmed 450mm feed slot and the customer’s installation conditions.
Copper Tool
The cutting tool is made of copper for use with the integrated heat-sealing and cutting structure. Tool dimensions, handle-hole profile and heating configuration are confirmed according to the bag design, material and approved drawing.
AirTAC Pneumatic Actuation
An AirTAC cylinder uses compressed air to perform the cutting stroke. Cylinder specification, air-supply conditions and operating cycle must match the tool structure, material and bag-making machine conditions.
Designed for Continuous Bag Production
The confirmed maximum speed range is 180-200 cycles/min. Actual production speed depends on the film material and thickness, heating condition, air supply, hole profile and synchronization with the bag-making machine.
Customizable Dimensions and Installation
Handle-hole size and profile, feed slot, die-base dimensions, heating configuration and mounting-hole positions can be evaluated from the bag drawing, material sample and equipment installation conditions.

Trial Operation, Working Conditions and Maintenance
Trial Run and Production
After installation, check cylinder movement, tool alignment, heating response and film feeding at low speed.
Run a small trial batch with the actual material and inspect handle-hole position, seal integrity, profile cutting and film surface condition.
Increase speed gradually while monitoring temperature, air supply, synchronization and material feeding.
Begin continuous production only after the heat-sealing and cutting result and dimensions have been confirmed.
Routine Maintenance
Check fasteners, air hoses, fittings, heating components and tool position before startup
Keep the feed slot and cutting area clean to prevent film or scrap buildup
Monitor the copper tool for wear or deformation and check for changes in seal and cut quality
Stop the machine immediately if abnormal temperature, air leakage, unusual noise, hole misalignment or incomplete cutting occurs
Maintain the guide, pneumatic, heating and temperature-control components according to the confirmed instructions
Safety notice: Before adjustment, cleaning or component replacement, stop the machine, disconnect heating power, release air pressure and allow hot areas to cool fully. Never place hands in the tool or heating area while the equipment is running, energized, pressurized or hot.
Quality Control, Shipping and After-Sales Support
Pre-Shipment Inspection
Each unit is checked against the confirmed order for hole-profile dimensions, die-base and feed-slot dimensions, mounting-hole positions, tool alignment, cylinder movement, air tightness, heating response, continuous operation and sample heat-sealing and cutting results. If the customer supplies material samples, a trial can be conducted under agreed conditions, and a test video will be provided for customer approval before shipment.
Packaging and Shipping

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.
