Paper Bubble Making Machines

Recycle Paper Cushion Making Machine

The SD-PB350 converts 125gsm or 180gsm waste kraft paper into embossed paper cushioning with a bubble structure in a single pass. The machine forms the cushioning paper from 100% recycled material, so a packaging producer can replace plastic bubble wrap with a paper alternative that is recyclable and accepted by retailers restricting plastics. The process includes unwinding, embossing, and rewinding in one continuous line.

  • Replaces plastic bubble wrap with a 100% recyclable paper cushion that meets retailer restrictions on plastic packaging
  • Uses 100% waste paper as raw material, reducing input costs and supporting sustainability goals
  • Single-pass operation with unwinding, embossing, and rewinding means one operator can manage the line
  • Working speed is fixed at 50 m/min, which is suitable for consistent production of roll-fed cushioning
  • Converting in house avoids the margin paid to a paper cushion supplier and reduces dependency on external supply
Problems It Solves

Why Buyers Choose It

  • Plastic bubble wrap is being rejected by end customers or banned in export markets due to environmental policies
  • Bought-in paper cushioning carries a supplier margin and long replenishment cycles
  • Manual placement of cushioning is slow and inconsistent compared to automated roll-fed systems
  • Using virgin paper increases material cost and reduces sustainability compliance
  • Lack of local production capacity for paper cushioning leads to reliance on imported rolls
Who It Is For

Who Runs This Machine

  • Packaging converters that process waste kraft paper and want to add a cushioning product
  • E-commerce fulfilment operators running roll-fed bagging lines that need paper cushioning
  • Paper mills and slitting houses looking to expand into value-added converting
  • Packers of fragile goods that must avoid plastic in final packaging due to customer requirements
Application

Where This Machine Is Used

  • Protective packaging producers switching from plastic bubble wrap to paper cushioning for e-commerce orders
  • Fulfilment centres and 3PLs using roll-fed paper cushioning on autobag lines for consistent packaging
  • Paper converters adding a value-added step to waste kraft paper by turning it into cushioning rolls
  • Packers of electronics, ceramics, and glassware needing a non-scratch, moisture-resistant cushioning layer
  • Export packers replacing imported plastic bubble wrap with locally converted paper cushioning

Process

How The Machine Runs

Step 1Load a waste kraft paper reel up to 600 mm diameter onto the 3 inch inflatable air shaft
Step 2Guide the web through the embossing rollers to form the bubble structure
Step 3Rewind the finished cushioning paper onto a 3 inch inflatable air shaft
Step 4Run at a fixed speed of 50 m/min for consistent output
Step 5Inspect the first few metres to confirm bubble formation and web tracking

Materials

  • 125gsm or 180gsm waste kraft paper
  • 100% recyclable material input
  • Optional laminated backing layer for enhanced moisture resistance (not specified in facts)

Quality Control

  • Inflatable air shafts ensure even tension and prevent paper damage during unwinding and rewinding
  • Fixed speed operation maintains consistent bubble formation across the roll
  • Machines are tested with customer-provided waste paper before shipment to verify performance
  • Web tracking is monitored during initial runs to prevent misalignment

Customisation

  • Power supply can be built to match the voltage and frequency of the destination country
  • Roll core size can be adjusted if different from 3 inch, though 3 inch is standard
  • Laminating unit can be added inline for moisture-resistant cushioning (not included in base model)
  • Embossing pattern can be modified for different cushioning cell sizes (not specified in facts)

Certifications

  • ISO9001:2000 certificate obtained in 2005
  • CE certificate obtained in 2006
Comparison

How It Compares

Buying finished paper cushioning rollsConverting in house removes the supplier margin but requires investment in the machine and storage of waste paper reels
Plastic bubble wrap machinesPaper cushioning is recyclable and accepted where plastics are restricted, though it is heavier per square metre than plastic film
Paper bubble cutting machinesThis machine forms the bubble structure; a cutting machine is needed to convert finished rolls into pads or sheets
Use Guide

Running It On Your Floor

  1. Ensure the waste kraft paper reel is within 600 mm diameter and 125gsm or 180gsm thickness
  2. Mount the reel on the 3 inch inflatable air shaft and inflate to secure the roll
  3. Start the machine at low tension and gradually increase to 50 m/min after web tracking stabilizes
  4. Check the first 1–2 metres of output for even bubble formation and no web misalignment
  5. Keep the embossing rollers clean to maintain consistent cushioning pattern and avoid paper tearing
