| Material Structure | Multi-layer laminate: Typically PET (outer for printability) / Aluminum Foil (barrier) / PE (inner
sealant)
. The clear window is often made from high-clarity BOPP or PET film
. |
| Sealing & Construction | 3-side heat seal (≥5mm width) for leak-proof integrity
. Pre-punched hanging hole (round or sombrero-shaped) for retail display is optional. Resealable zipper closure (e.g., press-to-close) for repeated use
. |
| Barrier Performance | Moisture Barrier: WVTR (Water Vapor Transmission Rate) is typically low, e.g., ≤0.5
g/m²/day (with AL foil), protecting contents from humidity
. Oxygen Barrier: OTR (Oxygen Transmission Rate) is also low, e.g., ≤0.05
cm³/m²/day·atm (with AL foil), to maintain product freshness
. UV Protection: Blocks >99% UV light
. |
| Clear Window | High-clarity BOPP or PET film (>90% light transmittance)
. Allows consumers to visually inspect the washing pods without
opening the package. |
| Physical Durability | Puncture & Tear Resistant
. Seal strength: Typically ≥25 N/15mm (ASTM F88). Withstands normal handling
during transportation and display. |
| Printing & Customization | Supports high-definition rotogravure printing. Customizable elements: logos, QR codes, batch dates, product
information
. |
| Dimensions & Capacity | Bag Width: Customizable (common range: 100–300 mm). Gusset Depth: 20–40 mm (expandable for bulkier products)
. Load Capacity: Suitable for various quantities of washing pods (e.g., 50g –
500g). |
| Compliance & Safety | Food Safety: Complies with FDA 21 CFR and EU 10/2011 for food contact if applicable
. 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) |
