Metallized Tri-Seal Bags For Floss - Aluminum Coating & High-Barrier
| Category | Specifications & Details |
|---|---|
| Material Structure | Multi-layer laminate: Typically PET (outer for printability) / Metallized Film (barrier) / PE (inner sealant). The metallized layer is often aluminum coating (e.g., VMPET) for high barrier properties. |
| Sealing & Construction | 3-side heat seal (≥5mm width) for leak-proof integrity. Tri-seal design ensures strong seams. |
| Barrier Performance |
Moisture Barrier: WVTR (Water Vapor Transmission Rate) is typically low, e.g., <0.5 g/m²/day (ASTM E96) Oxygen Barrier: OTR (Oxygen Transmission Rate) is also low, e.g., <0.5 cm³/m²/day*atm (ASTM D3985) UV Protection: Blocks >99% UV light (280-400nm) |
| Metallized Coating | Aluminum coating (e.g., vacuum metallized PET or VMPET) provides excellent light and gas barrier. It is more flexible and cost-effective than full aluminum foil. |
| Printing & Customization | Supports high-definition rotogravure printing. Customizable elements: logos, QR codes, batch dates, product information. |
| Physical Durability |
Puncture & Tear Resistant Seal strength: Typically ≥25 N/15mm (ASTM F88) |
| Dimensions & Capacity |
Bag Width: Customizable (common range: 50-200 mm for floss packages) Load Capacity: Suitable for various quantities of dental floss (e.g., 10-100 units) |
| Compliance & Safety |
Food Safety: Complies with FDA 21 CFR and EU 10/2011 for food contact Heavy Metals: Typically <0.1ppm (RoHS compliant) |
| Production & Logistics |
MOQ: 5,000-10,000 pieces (custom designs) Packaging Format: Rolls of 50-100 bags/pallet Lead Time: 15-25 days (FOB Shenzhen/Qingdao) |
