Product details
1. Composition:
- Base Material: Made from high-quality virgin or recycled kraft paper.
- Coating/Lamination: The outer layer is coated with polyethylene (PE) or polypropylene (PP), which provides waterproofing, grease resistance, and enhanced durability.
2. Grammage (Basis Weight):
- Standard Weight: Typically ranges from 70 GSM to 300 GSM, depending on the application and required strength.
- Heavier Grades: Higher grammage for more demanding applications may exceed 300 GSM.
3. Thickness (Caliper):
- Thickness Range: Generally varies from 100 microns to 500 microns, with typical thickness for laminated kraft paper around 150 to 300 microns.
4. Coating Properties:
- Plastic Coating Thickness: The thickness of the plastic coating usually ranges from 10 to 50 microns, depending on the required moisture and grease barrier properties.
- Gloss and Finish: Available in various finishes, including matte, gloss, or satin, depending on the application and aesthetic requirements.
5. Barrier Properties:
- Moisture Resistance: The plastic coating provides excellent moisture barrier properties, preventing water ingress and maintaining the integrity of the paper.
- Grease Resistance: Ideal for packaging greasy or oily foods due to its effective grease resistance, which prevents oil penetration.
6. Tensile Strength:
- Tensile Strength Values: Generally ranges from 20 to 50 N/mm², providing adequate strength for packaging applications and ensuring durability during handling and transport.
7. Printability:
- Surface Treatment: The laminated surface allows for high-quality printing using flexographic or digital printing techniques, making it suitable for custom branding.
- Ink Compatibility: Compatible with water-based and solvent-based inks, providing vibrant and durable print quality.
8. Heat Resistance:
- Temperature Range: Typically withstands temperatures up to 90°C (194°F), making it suitable for various cooking and food service applications.
9. Eco-Friendly Options:
- Recyclability: Depending on the plastic coating used, some variants are recyclable; however, laminated paper may require specialized recycling processes.
- Sustainably Sourced: Many products are available in FSC or PEFC certified materials, supporting sustainable forestry practices.
10. Customization Options:
- Custom Sizes: Available in various widths and lengths to meet specific customer requirements.
- Branding and Design: Custom printing options are available for branding, including logos and product information.
11. Applications:
- Food Packaging: Commonly used for wrapping greasy foods, bakery items, and take-out containers.
- Industrial Packaging: Suitable for packaging components that require protection from moisture and contamination.
- Craft and Stationery: Used in arts and crafts projects, as well as for creating durable stationery items.
12. Key Performance Indicators:
- Water Vapor Transmission Rate (WVTR): Typically less than 5 g/m²/24hr, ensuring minimal moisture absorption.
- Oxygen Transmission Rate (OTR): Effective barrier against oxygen transmission, depending on the coating type.
