| Place of Origin | Guangdong,China |
| ब्रांड नाम | Bright Pack |
| प्रमाणन | patent for invention、BRC、GRS |
| मॉडल संख्या | बी010 |
| Attribute | Description | Source Reference |
|---|---|---|
| Material Structure | Outer Layer: Biaxially Oriented Polyethylene Terephthalate (BOPET, 12-125μm thickness) with high tensile strength and transparency (≥85% light transmittance). Middle Layer: Vacuum-metallized aluminum (VMPET) for enhanced oxygen and moisture barrier. Inner Layer: Food-grade PE or CPP heat-sealable layer for airtight closure. |
|
| Barrier Performance | - Oxygen Transmission Rate (OTR): ≤3 cm³/m²·24h (blocks oxidation) - Water Vapor Transmission Rate (WVTR): ≤1.5 g/m²·24h (prevents moisture ingress) - UV light and odor blocking via aluminum layer. |
|
| Mechanical Strength | - Tensile strength: ≥150 MPa (longitudinal) - Tear resistance and puncture-proof design for durability during transport. |
|
| Temperature Range | - Operating range: -70°C to 150°C (suitable for freezing and microwave reheating) - Heat-sealing temperature: 120–150°C. |
|
| Customization | - Resealable zipper locks, one-way degassing valves (3–7 holes), tear notches. - Full-color digital printing for branding, holographic anti-counterfeit labels, matte/glossy finishes. |
|
| Sustainability | - Recyclable design (REACH compliant). - Optional biodegradable PLA composite layer (custom order). |
