Produktübersicht
High-quality recycled OCC waste paper sourced from post-consumer and post-industrial corrugated cardboard containers. This grade is ideal for international buyers seeking sustainable raw materials for pulp and paper production, offering excellent fiber strength for manufacturing new corrugated boxes, kraft paper, and other packaging products. As a key commodity in the global recycling market, our OCC meets stringent quality standards to ensure high yield and minimal processing issues in paper mills.
Technische Daten
Waste paper is classified into grades based on composition, source, and purity. Below is a summary of key ISRI-standard grades relevant to B2B recycling. Technical parameters include bale dimensions, weight, moisture content, and contaminant tolerances. All materials are baled to facilitate efficient transport and handling.
| Parameter | Spezifikation | Buyer Advantage |
|---|---|---|
| Grade Classification | ISRI Grade 11 (Old Corrugated Containers) – Corrugated containers with liners of test liner or kraft. Equivalent to EN 643 Grade 1.05 in European standards. | Ensures compatibility with global paper mill requirements, facilitating seamless integration into production lines. |
| Composition | Minimum 70-95% corrugated cardboard; balance may include minor acceptable papers (e.g., kraft bags under controlled limits). | High purity delivers consistent pulp quality, reducing rejects and improving end-product strength. |
| Feuchtigkeitsgehalt | ≤12% (average 8-10%; tested per AF&PA Moisture Guide). | Prevents mold growth during transit, ensuring material arrives in optimal condition for immediate use. |
| Contamination Levels | Prohibited materials (e.g., plastics, metals, glass, hazardous waste) ≤1%; Outthrows (e.g., boxboard, wax-coated paper) plus prohibitives ≤5%. Zero tolerance for medical, organic, food, radioactive, or toxic substances. | Low contamination minimizes cleaning costs and equipment damage, enhancing operational efficiency. |
| Fiber Quality | High-strength kraft/test liners; free of excessive dirt, ink, or adhesives. Fiber yield: 85-90%. | Provides superior tensile strength for recycled products, meeting demands for durable packaging in e-commerce and logistics sectors. |
| Bale Dimensions | Standard bale size: 110 cm x 110 cm x 180 cm (customizable); Weight per bale: 800-900 kg. | Compact and uniform bales optimize container loading, reducing shipping costs by maximizing payload (19-25 MT per 40′ container). |
| Color and Appearance | Natural brown kraft; clean and sorted, free of excessive printing or coatings. | Aesthetic consistency supports high-end recycled paper applications without additional bleaching. |
| Grade Number | Grade Name | Description | Prohibitive Materials Tolerance | Outthrows Tolerance | Typical Composition and Notes |
|---|---|---|---|---|---|
| (4) | Boxboard Cuttings | New cuttings of paperboard used in folding cartons, set-up boxes, and similar products. | ≤ 0.5% | ≤ 2% (plus prohibitives) | Clean manufacturing waste; free of wax, plastic, or inks. Ideal for high-quality paperboard recycling. |
| (10) | Magazines (OMG) | Coated magazines, catalogues, and similar printed materials; may include small uncoated news-type paper. | ≤ 1% | ≤ 3% (plus prohibitives) | Post-consumer printed matter; suitable for de-inking processes. |
| (11) | Old Corrugated Containers (OCC) | Corrugated containers with liners of test liner or kraft. | ≤ 1% | ≤ 5% (plus prohibitives) | Widely available from packaging waste; primary source for new corrugated medium. |
| (12) | Double-Sorted Old Corrugated (DS OCC) | Double-sorted corrugated from supermarkets/industrial facilities; free of boxboard, offshore corrugated, plastic, and wax. | ≤ 0.5% | ≤ 2% (plus prohibitives) | High-purity grade; minimizes contaminants for premium recycling applications. |
| (13) | New Double-Lined Kraft Corrugated Cuttings (DLK) | New corrugated cuttings with test liner or kraft; excludes treated mediums or insoluble adhesives. | None permitted | ≤ 2% (plus prohibitives) | Manufacturing cuttings; high kraft content for strength in recycled products. |
| (37) | Sorted Office Paper (SOP) | Primarily white and colored groundwood-free paper from offices; small groundwood content allowed. | ≤ 1% | ≤ 5% (plus prohibitives) | Office-generated; used for fine papers and tissue. |
| (40) | Sorted White Ledger (SWL) | Uncoated white groundwood-free ledger, bond, writing paper in sheets, shavings, or books. | ≤ 0.5% | ≤ 2% (plus prohibitives) | High-quality office waste; excellent for de-inked pulp. |
| (43) | Coated Book Stock (CBS) | Coated groundwood-free paper in sheets, shavings, or books; reasonable fine groundwood allowed. | None permitted | ≤ 2% (plus prohibitives) | Book production waste; for coated recycled papers. |
- Prohibitive Materials: Items that render the pack unusable or damaging (e.g., plastics, metals, wet-strength papers, hazardous waste). Zero tolerance for harmful substances like medical waste or toxics.
- Outthrows: Undesirable papers that detract from grade quality (e.g., groundwood in groundwood-free grades).
- Feuchtigkeitsgehalt: ≤ 12% (industry standard to prevent mold and ensure dry weight accuracy).
- Non-Paper Components: ≤ 1-2% (e.g., staples, adhesives; varies by grade).
- Bale Specifications:
- Dimensions: Typically 30″ x 42″ x 48″ to 30″ x 48″ x 60″ for efficient shipping.
- Weight: 400-1,000 kg per bale (minimum 35,000 lbs per shipment for truckload efficiency).
- Packaging: Wire-tied or strapped bales; stacked for container or truck loading.
- Density: 20-30 lbs/ft³ (compacted for cost-effective transport).
Custom grades or blends available upon request, with testing for purity via buyer-seller agreement.
Usage Guidelines
Waste paper grades are selected based on end-use requirements in recycling mills. Proper handling ensures optimal yield and minimal waste.
- Applications by Grade:
- OCC/DS OCC/DLK: Primarily recycled into new corrugated boxes, packaging mediums, and cardboard. High strength retention; yields 80-90% usable fiber.
- Magazines (OMG)/Coated Book Stock (CBS): De-inked for newsprint, tissue, or coated papers; suitable for graphic printing products.
- Sorted Office Paper (SOP)/Sorted White Ledger (SWL): High-quality pulp for writing papers, tissue, or hygiene products; low contaminant levels support fine paper production.
- Boxboard Cuttings: Used in recycled paperboard for boxes, cereal packaging, or folding cartons.
- Processing Recommendations:
- Storage: Keep bales dry and covered to maintain moisture below 12%; avoid exposure to contaminants.
- Integration: Feed into pulping systems; higher grades require less chemical treatment, reducing costs by 10-20%.
- Yield Optimization: Sort to minimize outthrows; typical mill recovery rate is 85-95% depending on grade purity.
- Safety: Ensure no hazardous materials; use PPE during handling to avoid dust.
For B2B procurement, we recommend volume contracts with quality sampling protocols to align with your mill’s specifications.
