EVOH High-Barrier Agricultural Packaging Material - China Suppliers & Factory for Pesticides and Seed Preservation
Performance Features of SVW™ EW-4401S in Agricultural Applications
1. Exceptional Oxygen and Moisture Barrier
EVOH provides over 10,000 times higher oxygen barrier than conventional polyethylene (PE), preventing oxidation and degradation of sensitive pesticide ingredients. Its precise moisture control (<2 g/m²·day) ensures a stable microenvironment for seed storage, maintaining viability over long periods. This makes EVOH an ideal choice for high-value seeds and biological pesticides.
2. Chemical Safety and Regulatory Compliance
EVOH is plasticizer-free, minimizing the risk of chemical migration. It fully complies with FDA and ISO 22000 food-contact standards, making it safe for high-value biotech and genetically modified (GM) seeds, as well as sensitive agrochemical formulations.
3. High Mechanical Strength and Thin-Film Capability
EVOH’s durable polymer structure supports ultra-thin film designs as low as 15 μm, perfect for small-dose pesticide sachets and lightweight packaging. This allows precision agriculture applications to reduce packaging material usage while maintaining full protection of the contents.
4. Sustainable and Recyclable Innovation
Modern EVOH composite films, such as EVOH+PP, leverage molecular self-assembly technology to separate the barrier and heat-sealing layers efficiently, enabling full recyclability without compromising barrier performance. This innovation supports sustainable agricultural packaging solutions, aligning with ESG and global environmental initiatives.
