Heavy-Duty Kraft Laminated Poly Sack Industrial Wrapping Paper
Protect heavy structural goods, wire coils, and metal profiles with heavy-duty kraft laminated poly sack industrial wrapping paper. Engineered as a superior alternative to traditional burlap wrapping and standard woven lamination, this hybrid composite combines puncture-resistant polypropylene/polyethylene (PP/PE) woven plastic sacks with high-absorbency kraft paper to deliver exceptional burst strength and moisture control.
Specifically designed for steel and heavy industrial products, this packaging material regulates moisture dissipation caused by environmental temperature swings. While the outer woven matrix withstands high tension and sharp edges, the inner kraft paper actively absorbs internal condensation, keeping packaged metal dry and protected during long-term storage and rough transit.
Engineered for High-Tensile Steel Packaging and Condensation Absorption
Heavy goods packaging demands high burst strength alongside active microclimate regulation. Conventional burlap often sheds fibers, lacks uniform tensile resistance, and fails to handle condensation properly. This PP/PE sack and kraft paper laminate solves those weaknesses by integrating tear-resistant synthetic weave with moisture-buffering natural fibers.
Whether wrapping heavy steel coils, sheet bundles, or machinery parts, buyers can customize paper weights and synthetic sack denier, selecting specific weave patterns to meet their exact load-bearing and water-resistance requirements.
Key Features & Material Benefits
- Dual-Action Composite: Integrates high-strength PP/PE woven plastic sack fabric with moisture-absorbing kraft paper.
- Internal Condensation Control: The laminated kraft layer absorbs ambient moisture inside large packaging spaces, minimizing temperature-driven sweat on steel.
- High Tensile & Burst Resistance: Provides the structural burst strength needed to bundle heavy steel plates, wire, pipe, and machinery parts.
- Water-Resistant Barrier: Exterior poly-weave layer provides dependable short-term water resistance against outdoor elements.
- Customizable Denier & Weave: Select from varied kraft paper grammages and synthetic fiber deniers or weave styles (carpenter/flat) to match duty requirements.
- Clean Alternative to Burlap: Overcomes fiber shedding, dust, and uneven strength associated with traditional burlap wrapping paper.

Frequently Asked Questions
Why is this material better than conventional burlap wrapping for steel?
Traditional burlap easily frays, produces fiber lint, and has inconsistent burst strength. This composite combines the structural integrity of synthetic PP/PE fiber weave with moisture-absorbing kraft paper, preventing moisture buildup on steel while maintaining extreme tear resistance.
How does the kraft paper handle packaging condensation?
Large metal packages naturally experience temperature shifts between day and night, producing internal condensation. The laminated kraft paper layer actively absorbs this trapped moisture before it pools or settles onto metal surfaces.
Can we choose different paper weights and woven fiber strengths?
Yes. Both the kraft paper basis weight and the synthetic fiber denier/weave density are fully customizable to provide the ideal balance of burst resistance, absorbency, and cost efficiency for your specific shipping requirements.
