Honeycomb Paper Core Sleeve Making Machine
The SD-PC900 produces paper core sleeves for honeycomb cushioning from kraft paper reels. It forms a continuous paper tube with a core structure that supports the honeycomb layer during transport and storage. The machine handles 50 to 70 gsm paper and builds sleeves in lengths from 200 to 900 mm. It is designed for packaging producers who need to make their own paper cores instead of buying them from third parties.
- Makes paper core sleeves in-house to reduce dependency on external suppliers
- Uses water based glue for a safer, environmentally compliant process
- Servo motor and PLC control allow precise, repeatable operation with touch screen interface
- Adjustable feeding capacity allows 30 to 50 cores per group, with multiple cores fed at once for shorter lengths
- Core length and width can be set to match downstream honeycomb forming requirements
Why Buyers Choose It
- Buying paper core sleeves from third parties adds cost and lead time to the production process
- Plastic cores are not recyclable and are being rejected by retailers and logistics providers
- Manual core assembly is slow and inconsistent compared to automated sleeve forming
- Lack of core support during honeycomb formation can cause collapse or misalignment in the final product
Who Runs This Machine
- Packaging producers converting kraft paper into honeycomb cushioning with internal core support
- Paper slitting and converting facilities adding core sleeve production to their service offerings
- Fulfilment centres or packers using honeycomb wrap with paper cores for high-volume fragile item packaging
- Companies replacing plastic cores with paper cores due to end-customer restrictions or environmental policies
Where This Machine Is Used
- Protective packaging producers building honeycomb cushioning rolls that require internal paper cores
- Paper converters adding core sleeve production to their existing kraft paper processing line
- E-commerce packers using honeycomb wrap with paper cores to protect fragile items like glassware and ceramics
- Manufacturers replacing plastic cores with paper cores to meet sustainability or customer packaging requirements

How The Machine Runs
Materials
- Kraft paper reels from 50 to 70 gsm
- Water based glue for core bonding
- Optional core backing material if required for structural reinforcement
Quality Control
- Servo motor ensures consistent speed and tension during core formation
- Touch screen interface allows monitoring of core length, width, and feeding cycle
- PLC control maintains process stability and reduces variation between runs
- Glue application is calibrated to prevent dry spots or excess glue on the core
- Machine is tested with customer paper before shipment to verify core formation
Customisation
- Core length and width can be adjusted to match downstream honeycomb forming requirements
- Feeding group size can be modified for different core batch sizes
- Power supply can be built to match voltage and frequency of the destination country
- Core cutting length can be set via the touch screen interface for different product lines
Certifications
- ISO9001:2000 certificate obtained in 2005
- CE certificate obtained in 2006
How It Compares
| Buying pre-made paper core sleeves | In-house production removes supplier dependency and cost, but requires space and operator time for setup and maintenance |
|---|---|
| Plastic core sleeves | Paper cores are recyclable and accepted where plastics are restricted, though they may have lower structural rigidity |
| Manual core assembly | Automated forming is faster and more consistent, but requires initial investment and training |
Running It On Your Floor
- Ensure the kraft paper reel is within 50 to 70 gsm and properly loaded on the unwinding stand
- Set the desired core length and width on the touch screen interface before starting
- Verify glue application is even and the paper wraps smoothly around the mandrel
- Check the first few cores for correct dimensions and glue bond strength
- Adjust the feeding group size based on the core length to maximize throughput
