Kraft Bubble Paper Forming Machine with Laminating inline
The SD-PB1300 forms embossed bubble paper from kraft paper reels and laminates a flat backing layer inline to improve strength and air retention. The machine processes a top layer of kraft paper through heated concave-convex rollers to form bubbles, then applies a second paper layer to the back for structural support. This creates a cushioning material suitable for e-commerce packaging and protective wrapping, replacing plastic bubble wrap in markets where it is restricted.
- Produces laminated kraft bubble paper with improved strength and air retention compared to single-layer versions
- Inline lamination prevents bubble collapse and maintains cushioning performance during handling
- Adjustable embossing patterns allow custom cell designs for different protection needs
- Speed range of 0 to 50 m/min allows matching output to production line capacity
- Eliminates the need to buy finished kraft bubble paper, reducing material cost and lead time
Why Buyers Choose It
- Plastic bubble wrap is being rejected by retailers and end customers in key export markets
- Single-layer kraft bubble paper lacks sufficient strength and air retention for effective cushioning
- Buying finished laminated bubble paper from suppliers adds cost and delays replenishment
- Manual cushioning is inconsistent and too slow for high-volume packaging operations
- Inconsistent roll lengths and weak bubble structure lead to product damage in transit
Who Runs This Machine
- Packaging producers converting kraft paper reels into laminated bubble paper for sale
- E-commerce operators running automated bagging lines that require roll-fed cushioning
- Paper slitting houses adding a forming and laminating step to their existing operations
- Contract packers supplying protective packaging to consumer goods brands

How The Machine Runs
Materials
- Kraft paper reels from 120 gsm and above
- Flat paper backing layer for laminating the reverse side
- Optional custom embossing patterns based on customer drawings
- Adhesive for laminating process (supplied separately or integrated)
Quality Control
- Heated embossing rollers maintain consistent bubble formation across the width
- Lamination bond strength verified during test runs with customer paper
- Speed and pressure settings calibrated to prevent web misalignment or layer separation
- Machine tested with customer material before shipment to confirm output quality
- Roll length and tension monitored during rewinding to avoid wrinkles or slippage
Customisation
- Embossing patterns can be customized beyond standard options including semi-circular ball, wave, hexagon, and star
- Roller diameter and length adjusted to match specific paper width requirements
- Power supply built to the voltage and frequency of the destination country
- Rewinding shaft size and configuration tailored to customer core stock
- Automatic cutting and stacking system added inline upon request
Certifications
- ISO9001:2000 certificate obtained in 2005
- CE certificate obtained in 2006
How It Compares
| Buying finished laminated kraft bubble paper | Converting in house removes the supplier margin but requires investment in machine and kraft reel inventory |
|---|---|
| Single-layer kraft bubble paper machine | Inline lamination improves strength and air retention, making it more effective as a cushioning material |
| Plastic bubble wrap machines | Paper-based bubble is recyclable and accepted in markets restricting plastic, though it is heavier per square metre |
Running It On Your Floor
- Ensure the kraft paper reel is loaded securely on the unwinding stand with proper alignment
- Set the desired speed using the frequency converter before starting the run
- Adjust pressure on the embossing rollers to match paper thickness and desired bubble size
- Verify the lamination bond quality on the first few metres of output
- Keep embossing rollers clean to maintain consistent pattern formation and avoid paper tearing
