Reel Packaging & Marine Protection Engineering
Engineered with radial edge guards, moisture barrier wrapping, and core protection for heavy container rolls.
- • 3 to 5 Layers Extensible Kraft with inner PE moisture barrier film.
- • Protects paper roll edges against sea moisture condensation and humidity.
- • Sealed outer wrap preventing dust, scuffing, and transit abrasion.
- • Corrugated Circular End Discs clamped at both reel faces.
- • Heavy-duty flanged plastic/fibre radial chine protectors along outer rims.
- • Prevents roll edge denting during crane and clamp-truck operations.
- • Heavy Pressed Composite / Steel Plugs inserted into 3" or 6" core ends.
- • Prevents core collapse or out-of-round deformation under stacking pressure.
- • Grooved timber floor chocks and heavy polyester strapping for zero rolling.
Full Container Load (FCL) Stowage: 20GP vs 40HQ
Optimized for maximum ocean freight payload, gross weight compliance, and port terminal handling.
| Container Loading Parameter | 20GP Container (Standard Heavy Load) | 40HQ Container (High Cube Max Payload) |
|---|---|---|
| Reel Stowage Configuration | Eye-to-Sky (Vertical on Pallets) or Eye-to-Wall (Horizontal) | Multi-Row Staggered Horizontal or Vertical Palletized |
| Net Cargo Tonnage | ~ 15.0 - 18.0 Metric Tons | ~ 25.0 - 28.0 Metric Tons (Max Weight) |
| Total Paper Reels Loaded | 14 - 24 Reels (depending on diameter & width) | 28 - 44 Reels (depending on diameter & width) |
| Dunnage & Securing System | Grooved Timber Wedges + Heavy Polyester Ratchet Straps | Heavy Dunnage Airbags + Timber Floor Bracing + Web Straps |
| Freight Economic Advantage | Lower trial capital commitment / flexible port routes | Lowest sea freight cost per metric ton |

Frequently Asked Questions for Kraft Paper – Wholesale Packaging and Industrial Paper Buyers
What burst factor and grammage grades of Kraft paper do you supply?
We produce unbleached natural brown kraft, bleached white kraft, and heavy linerboard ranging from 60 GSM up to 250 GSM. Our sack kraft delivers a burst index of ≥ 3.6 kPa·m²/g and high tensile energy absorption (TEA) suitable for cement sacks, flour bags, and corrugated packaging.
Can Kraft paper reels be slit to custom widths for our bag or corrugating machines?
Yes. We provide precision rotary reel slitting from 500 mm up to 2,400 mm width with a tolerance of ± 1.0 mm. Standard inner core diameter is 76 mm (3 inches) or 152 mm (6 inches) with reinforced composite or steel end caps.
How are the paper reels protected against rain and sea moisture during ocean transit?
Every reel is wrapped in 3 to 5 layers of heavy extensible kraft linerboard with an internal PE moisture barrier film. Reel ends are fitted with corrugated circular discs and radial chine edge protectors, while container floors are lined with impermeable PE sheeting and Calcium Chloride desiccant bags.
What is the minimum order quantity (MOQ) and container tonnage?
Minimum order is 1 x 20ft container (~15 - 18 Metric Tons). For maximum sea freight economy, a 40HQ container accommodates ~25 - 28 Metric Tons. Mill Test Certificates (MTC) and weight slips are issued with each container dispatch.
