Premium multi-layer aluminized paper roll engineered for high-barrier automated packaging.
Multi-layer aluminized paper rolls are high-performance flexible packaging substrates consisting of a paper base laminated with a vacuum-metallized PET or aluminum layer. These rolls provide an optimal balance between superior barrier properties (moisture, oxygen, light) and the natural aesthetics of paper, making them ideal for premium tea bag outer wrappers, individually wrapped chocolate pieces, and dry food sachets.
Unlike solid aluminum foil, the metallization process deposits a microscopic layer of aluminum (typically 10-50 nanometers) onto the paper substrate, achieving up to 90% of the barrier performance at significantly lower material cost and weight.
| Parameter | Standard Spec | Custom Option |
|---|---|---|
| Base substrate | 40-120 GSM food-grade kraft/white kraft | FSC-certified paper available |
| Metallized layer | VMPET 12-25 micron | Adjustable thickness |
| Layer structure | 2-ply (Paper/VMPET) or 3-ply (Paper/VMPET/PE) | EVOH layer addable |
| Total thickness | 80-200 micron | Based on structure design |
| Width range | 50-1000mm | Customized per equipment |
| WVTR (Water Vapor Transmission Rate) | <5 g/m²/day | <1 with EVOH layer |
| OTR (Oxygen Transmission Rate) | <10 cm³/m²/day | Adjusted per metallization |
| Printing | Up to 10 colors (flexo/gravure) | Inside/outside printing |
| Certifications | FDA 21 CFR 176.170, EU 10/2011 | SGS test reports available |
| Minimum order quantity | 300 kg | Sample orders from 50 kg |
The primary value of aluminized paper rolls lies in their engineered barrier against three degradation factors:
1. Moisture Vapor Transmission (MVTR): In multi-layer constructions, the metallized PET layer acts as the primary moisture barrier. A standard 12-micron VMPET layer achieves MVTR of 2-5 g/m²·day, extending shelf life of moisture-sensitive products (e.g., tea, powdered supplements) from 6 months to 18-24 months. XLD considers a 20-micron VMPET layer to be the best match between cost and effectiveness.
2. Oxygen Transmission (OTR): The aluminum deposition creates a near-impermeable oxygen barrier. For oxygen-sensitive products like green tea, this prevents oxidation that causes color darkening and flavor loss. Multi-layer structures with EVOH interlayer can achieve OTR <1 cm³/m²·day.
3. Light Barrier: Complete opacity (>99% light blockage) protects light-sensitive compounds in tea polyphenols and vitamin powders. The metallized layer also provides a premium metallic sheen that elevates shelf presence compared to standard kraft paper.
Metallized vs. Solid Aluminum Foil: While solid foil provides absolute barrier (OTR ≈ 0), aluminized paper offers 80-95% of the performance at 30-50% lower material cost and weight. For products with shelf life requirements under 24 months, aluminized paper is the cost-optimized choice.
Follow this four-step methodology to determine the correct specification for your application:
| Product Type | Recommended Structure | Expected Shelf Life |
|---|---|---|
| Tea (Black/Pu-erh) | Paper/VMPET (2-ply) | 12-18 months |
| Tea (Green/White) | Paper/VMPET/EVOH/PE (4-ply) | 18-24 months |
| Chocolate/Candy | Paper/VMPET/PE (3-ply) | 12-15 months |
| Health Supplements | Paper/VMPET/AI/PE (4-ply) | 24+ months |
Our aluminized paper rolls are engineered for compatibility with major packaging equipment:
| Equipment Brand | Compatible Models | Width Tolerance |
|---|---|---|
| IMA | C24, C27, C40 series | ±0.5mm |
| TEEPACK | Prima, Perfecta | ±0.3mm |
| FUSO | FN, FP series | ±0.5mm |
| Pharmaceutical packaging machines | Custom available | Per equipment specs |
Important: Provide your machine model and die width when requesting a quote to ensure dimensional compatibility.
| Visual Effect | Recommended Process | Application Scenario |
|---|---|---|
| High-gloss metallic | Metallized + varnish | Mass consumer market |
| Matte luxury | Metallized + matte lamination | Premium tea/chocolate |
| Partial emboss | Metallized + embossing | Brand differentiation |
| Traceable QR code | Inner-layer printing | Anti-counterfeit/marketing |
While aluminized paper rolls cost 15-25% more than standard PE-laminated paper, the extended shelf life reduces product waste by an estimated 10-18%, resulting in lower total packaging cost per unit sold.

Aluminized paper uses vacuum-deposited aluminum (10-50nm thickness), achieving 80-95% of solid foil's barrier performance at 30-50% lower material cost. Choose aluminized paper for cost-sensitive applications with <24-month shelf life requirements; choose solid aluminum foil for long-term storage (>24 months) or extreme barrier needs (OTR ≈ 0). XLD provides both options—specify your barrier requirement when inquiring.
Standard aluminized paper (paper/VMPET/PE) is not widely recyclable because of its metal-polymer composite. However, XLD offers a mono-material recyclable variant (paper/PE, no aluminum) with WVTR <15 g/m²/day, suitable for brands with explicit sustainability commitments. Approximately 30% of our tea packaging clients have switched to the recyclable variant since 2024.
Yes. Our standard aluminized paper rolls are produced to ±0.3mm width tolerance and compatible with IMA C24/C27/C40, TEEPACK Prima, and FUSO FN series. For first-time trials, we provide a 50-meter test roll at sampling cost (refundable upon bulk order). Machine compatibility is typically confirmed within 3 production runs.
Standard MOQ is 100 kg per specification. For custom printing, MOQ is 500 kg per design. Sample orders (50-100 kg) are available at 20% premium. Lead time is 10-15 working days for standard orders, 15-21 days for custom printing. Payment terms: 30% deposit, 70% before shipment. Net-30 terms available for orders >1,000 kg upon credit approval.
