Efficient Single Screw Plastic Extruder for Bubble Wrap Production

This machine uses two independent single-screw extruders, one for each layer. This design offers excellent stability, simplicity, and cost-effectiveness for processing common polyolefins like LDPE, whereas twin-screw extruders are typically used for more complex compounding tasks.

Yes. The high-compression 34:1 L/D screw is specifically designed to handle the variable flow characteristics of 100% recycled materials effectively, supporting sustainable production goals.

The system uses a PLC-controlled metering unit to measure the film length. Once the preset length is reached, a cutting mechanism (e.g., a rotary cutter or guillotine) automatically activates, ensuring each roll or sheet is precisely cut before winding.

The perforator adds a line of micro-perforations to the film, making it easier to tear by hand, allowing for controlled air cushion separation, and improving flexibility for wrapping irregular shapes.

This optional die incorporates integrated internal heating, which targets heat directly to the material flow. This can reduce overall heating energy consumption by up to 30% compared to traditional externally heated T-dies.
