222gsm Kraft Paper for HPL – Customizable Grammages 198g-400g
Using high-basis-weight kraft paper shows significant advantages. In HPL production, compared with lower-basis-weight grades, 222gsm kraft paper reduces the number of sheets required per HPL, which improves resin impregnation efficiency and lowers both production and labor costs.
Our factory holds strong advantages in producing high-basis-weight kraft paper. Equipped with advanced new machines featuring the latest technology, we ensure stable production. At the same time, strong controllability in the pulping process guarantees pulp stability, which is the key to consistent product quality.
In addition, we offer customized services with multiple basis weights such as 222gsm, 280gsm, 290gsm, 300gsm, and 400gsm to meet different HPL production requirements.

Industrial Substrate Field | Enhances composite board rigidity, resists deformation during long-term use | 280gsm–400gsm | Compact extra-thick boards, soundproof board reinforcement layers
HPL 222gsm kraft paper Production Efficiency
HPL Sheet Quantity (15mm Thick HPL) | 15 sheets (approx. 0.1mm thickness per sheet after lamination) | 5 sheets (approx. 0.3mm thickness per sheet after lamination) | Sheet count reduced by 67%, lowering operational complexity
Resin Impregnation Efficiency | Multiple impregnation steps, total time approx. 30 minutes | One-time impregnation, total time approx. 10 minutes | Efficiency improved by 200%, shortening production cycle
Labor Cost | Requires 2 workers to lay paper, time approx. 15 minutes | One worker can lay paper independently, time approx. 5 minutes | Labor cost reduced by 60%, minimizing manpower input
Material Waste | Multiple sheets stacked easily misaligned, waste rate approx. 5% | Fewer sheets stacked neatly, waste rate ≤1% | Waste rate reduced by 80%, saving raw material cost
Production Guarantee: Precise Grammage via Advanced Equipment
Advanced Equipment: Ensuring Production Precision
We use a German Fourdrinier paper machine installed in 2023, supported by a closed-loop production system. Key advantages include:
Real-time monitoring: Basis weight deviation ≤±2g/㎡, much tighter than the industry average ±5g/㎡.
High-pressure pressing: Uniform density with deviation ≤±0.03g/cm³.
Gradient drying: Temperature control within ±1℃, ensuring thickness tolerance ≤±0.02mm.
Precise Pulping: Guaranteeing Consistency
Stable strength and accurate basis weight come from controlled pulping:
Golden ratio pulp: 80% softwood + 20% hardwood, fiber length deviation ≤5%.
Beating degree: Fixed at 32–35°SR, deviation ≤1°SR.
Pulp concentration: Maintained at 3.5%–4.0% with real-time detection.
With this system, every batch of 222gsm Kraft Paper for HPL keeps consistent weight and strength, cutting HPL rework rate to below 1%.
Stability: Solving Customer Pain Points
Batch differences reduced: Tight ±2g/㎡ control avoids HPL thickness deviation, lowering rework rate to <1%.
Reliable supply: Equipment failure ≤0.5% monthly, pulping pass rate ≥99.8%, standard orders delivered within 7 days.
High-grammage kraft paper requires precision and stability, and we ensure both to secure product quality.

Heavy Duty Kraft: Grammage Boosts HPL Strengt
Heavy duty kraft paper has large thickness, high density and strong mechanical strength and durability. It is usually used in occasions with high packaging strength requirements, such as industrial packaging, building materials packaging and so on. Heavy kraft paper is not easy to tear, damage, provides very good protection.
Strength of Heavy Duty: 222gsm-400g for HPL
Heavy duty kraft paper lives up to its name, offering enhanced thickness and density for demanding applications needing extra toughness. Through careful production controls, heavy duty kraft achieves exceptional traits beyond regular kraft.
Manufacturing starts with using the strongest long fiber wood pulps, then refining them to maximize fiber bonding strength. Wet pressing removes excess water to increase density. Drying tension augments stiffness and tear resistance. The result is thick, dense sheets with high bulk, tear resistance, and burst strength.
Heavy duty kraft excels in heavy-duty packaging and wrapping where regular kraft easily fails. The dense paper prevents tearing from container edges and resists punctures from shifting loads. It provides rigid wrapping support and containment for heavy items during transport or storage.
Additional industrial uses include sediment filters in food production, scrubbing pads, industrial wipes, and backing for abrasive discs. The sturdy paper withstands rubbing, scouring, and exposure to oils or grease. It replaces light papers unfit for heavy wear and cleaning uses.
With careful sourcing and production controls, pulp can be transformed into a remarkably robust kraft paper. Heavy duty kraft judiciously levers papermaking techniques to achieve strength and durability similar to light cardboard, at a fraction of the cost. It brings the advantages of kraft to demanding applications.
