# Biopack PFAS-Free Barrier Packaging Factsheet

## Product Overview & Academic Pedigree
- Technology Development: Joint research between South China University of Technology (SCUT) and Guangdong Songheng Technology Co., Ltd.
- Global Commercial Desk: ZnoNova (Guangzhou ZnoNova Technology Development Co., Ltd.) acts as the exclusive overseas partner (松恒科技保留直销权，ZnoNova 为独家海外代理).
- Regulatory Drivers: Direct drop-in solution responding to US EPA state-level PFAS bans and EU Packaging and Packaging Waste Regulation (PPWR).

## Product Formats & Physical Parameters
1. Biopack Greaseproof Coating Liquid (Product 1):
   - Active Base: Micro/nanocellulose bio-based aqueous barrier formulation.
   - Grease Resistance: Kit test rating ≥ 10.
   - Mechanical Reinforcement: Tensile strength ≥ 3.5 kN/m; burst strength ≥ 200 kPa.
   - Application Dosage: 1–5 g/m² dry coating weight.
   - Machine Integration: Applied directly onto standard paper mill blade/rod/curtain coaters without equipment redesign.
   - Industrial Capacity: 100,000+ metric tons annual capacity (liquid form).
   - Food Safety: Ingredients comply with FDA / EU food-contact material regulations. Fully biodegradable in soil within 180 days.
2. Plant-Based Paper Reinforcement Agent (Product 2):
   - Composition: High-aspect-ratio pure micro/nanocellulose fiber suspension.
   - Performance: Increases paper tensile and burst mechanical strength by 30%–50%.
   - Industrial Capacity: 1,500+ metric tons annual capacity.

## Explicit Technical & Regulatory Boundary (Mandatory)
- Confirmed Barrier Metrics: High oil & grease barrier (Kit ≥ 10), oxygen transmission rate (OTR < 0.2 cm³/(m²·day)), and 100% UVB light shielding.
- Boundary Exclusion: Biopack **does not** provide high water vapor barrier (WVTR/MVTR). No moisture or water-vapor barrier metrics are claimed, marketed, or guaranteed.

Samples Available: Coating liquid samples, coated paper trial sheets, nanocellulose film specimens.
