Kraft Paper Bubble Making Machine
The SD-PB600 converts a reel of kraft paper into embossed bubble cushioning paper in a single pass. The machine uses vertical upper and lower concave-convex rollers to press semi-circular, wave, three-dimensional hexagon, or four-pointed star patterns into the paper. This creates a paper-based cushioning material that can replace plastic bubble wrap in e-commerce and industrial packaging, with the option to laminate a soft white backing layer. The process is continuous, so a packaging producer can make its own protective paper instead of buying finished rolls.
- Replaces plastic bubble wrap with a paper cushion that is recyclable and accepted by retailers restricting plastics
- Unwinding, embossing, and rewinding happen in one process so one operator can run the line
- Working speed is adjustable from 0 to 50 m/min so output can be matched to downstream demand
- Automatic meter counting stops the machine at the set length and keeps roll lengths consistent
- Converting your own kraft reels removes the margin paid to a paper bubble supplier
Why Buyers Choose It
- Plastic cushioning is being refused by retailers and end customers in export markets
- Bought-in paper bubble carries a converter margin and long replenishment lead times
- Manual wrapping of fragile goods is slow and inconsistent between operators
- Roll length variation causes short rolls and customer complaints
Who Runs This Machine
- Packaging converters that already buy kraft paper in reels and want to add a cushioning product
- Paper mills and trading companies adding a value-added converting step
- Fulfilment operators packing several thousand fragile orders a day
Where This Machine Is Used
- Protective packaging producers making paper bubble rolls for e-commerce fulfilment centres
- Packers protecting electronics, glassware, and ceramics that scratch easily in transit
- Converters supplying paper bubble cushioning to furniture and appliance manufacturers
- Export packers replacing imported plastic bubble film with a locally converted paper cushion

How It Compares
| Buying finished paper bubble rolls | Converting in house removes the supplier margin but you carry the kraft reel inventory and the machine investment |
|---|---|
| Plastic bubble wrap machines | Paper bubble is recyclable and accepted where plastics are restricted, though it is heavier per square metre than air-filled film |
| Paper Bubble Cutting Machine | This machine forms the embossed bubble web; the cutting machine converts finished bubble paper into sheets or pads |
Running It On Your Floor
- Load a kraft reel up to 1200 mm diameter and 1 ton onto the inflatable air shaft
- Set the target roll length on the meter counter before starting the run
- Start slow and raise speed with the inverter until the web tracks steadily
- Check embossing depth and pattern clarity on the first metres before committing the reel
- Keep the embossing rollers clean of paper dust to protect the cutting edge
