Key Features
Long-Fiber Kraft Pulp — Higher Tensile and Tear Strength
The sulfate pulping process preserves long cellulose fiber chains that mechanical pulping breaks down. The result is tensile strength 2–3 times greater than standard packaging paper and tear resistance approximately 30–40% higher — providing reliable protection against tearing during wrapping, interleaving, and transit handling.
Natural Brown and Bleached White Grades
Natural brown (unbleached) kraft retains the unmodified fiber structure for maximum mechanical strength — the preferred specification for industrial wrapping and interleaving where strength is the priority. Bleached white undergoes additional processing that slightly reduces tensile strength but produces a clean surface suitable for printing, premium packaging, and food-grade applications where appearance matters.
60–120 GSM Basis Weight Range
Light-to-medium grades (60–80 GSM) are suitable for interleaving between stacked components, wrapping lightweight assemblies, and lining carton interiors. Heavier grades (90–120 GSM) provide better puncture resistance and tear strength for wrapping sharp-edged or heavy industrial parts, and for multi-layer sack construction.
Rolls and Sheets — Custom Dimensions
Available in custom roll widths and lengths for packing-line dispensers, and in cut sheet formats for manual wrapping and interleaving operations. No minimum on custom dimension runs — roll widths, roll lengths, sheet sizes, and basis weight are all specified per order.
Recyclable and Biodegradable
Industrial kraft paper is fully recyclable through standard paper waste streams — recycling rates for industrial paper exceed 80%. It is also biodegradable under industrial composting conditions, making it a straightforward choice for manufacturers reducing plastic-based wrapping materials or meeting export market sustainability documentation requirements.
Small Batch Orders Welcome
Custom roll and sheet specifications are available without large minimum order requirements. Suitable for manufacturers in prototyping, production scale-up, or seasonal demand situations where flexibility in order volume matters.
Applications
Interleaving Between Stacked Metal and Machined Components
Precision-machined metal parts, stamped components, and sheet metal blanks are prone to surface-to-surface contact scratching during palletizing and transit. Kraft paper interleaf sheets placed between each layer absorb contact load and prevent metal-on-metal friction — a standard practice in machining and metal fabrication operations across Southeast Asia. Heavier grades (90–120 GSM) are specified for burr-edged or sharp-profiled components.
PCB and Electronic Assembly Interleaving
Printed circuit boards, display panels, and flat electronic assemblies are typically stacked in shipping cartons with interleaving layers to prevent board-to-board contact damage. Kraft paper at 60–80 GSM provides adequate separation stiffness for this application while remaining thin enough not to significantly increase carton height for stacked boards.
Surface Protection During Manufacturing and Transit
Painted components, coated panels, optical surfaces, and precision-machined faces require surface protection between manufacturing steps and during transit. Kraft paper sheeting is applied directly to the surface (taped or wrapped in place) to prevent contact scratches from handling, stacking, and transport vibration.
Void Fill and Cushioning in Industrial Shipping Cartons
Kraft paper rolls are widely used as void fill and cushioning filler inside export shipping cartons. Paper crumpled or folded into carton voids restricts product movement under transit vibration and drop conditions — a lower-cost, recyclable alternative to foam peanuts and plastic air cushions for less-fragile industrial goods.
Frequently Asked Questions
What is the difference between natural brown and bleached white kraft paper?
Natural brown (unbleached) kraft retains the unmodified cellulose fiber structure for maximum tensile and tear strength — the standard specification for industrial wrapping and interleaving applications where strength is the priority. Bleached white undergoes an additional chemical processing step that slightly reduces mechanical strength but produces a clean white surface suited for printing, consumer-facing packaging, and applications where appearance is important. If strength is the only requirement, natural brown is the better choice.
What basis weight should I select for my application?
For light interleaving between smooth-surfaced components (PCBs, display panels, flat assemblies), 60–80 GSM provides adequate separation stiffness. For wrapping sharp-edged or heavy industrial parts where puncture resistance and tear strength matter — machined metal components, castings, or tools — 90–120 GSM is more appropriate. If you are unsure, contact us with your component weight and profile description and we can recommend a specification.
Are custom roll widths and sheet sizes available?
Yes — all roll widths, roll lengths, and sheet formats are custom manufactured to your specification. There is no standard width constraint. Contact us with your required dimensions, basis weight, and grade, and we will confirm availability and lead time.
Is kraft paper suitable as a plastic-free void fill for export shipments?
Yes. Crumpled or folded kraft paper is a widely accepted recyclable void fill material for export cartons. It satisfies plastic-free packaging requirements common in EU, Japanese, and sustainability-committed buyer programs — and is recyclable through standard paper waste streams at destination, unlike foam peanuts or plastic air cushions. For fragile goods requiring more structured cushioning, see our kraft bubble paper roll for a plastic-free cushioning alternative.
