PE Coated Kraft Paper Bag 120 - 160gsm Rain Resistant Waterproof Honeycomb Packing Paper

HUANCHEER specializes in functional paper packaging that bridges the gap between sustainability and performance. Our PE-coated waterproof kraft paper bags are the result of advanced lamination technology — applying a precise layer of polyethylene resin onto high-quality kraft paper using extrusion coating processes. This creates a paper-based bag with superior moisture barrier properties while maintaining recyclability.

We source kraft paper from FSC-certified mills, and our PE coating is food-grade and FDA-compliant for dry food contact. Our production facility operates ISO 9001-certified lines capable of outputting over 500,000 waterproof bags per week. We offer fully customizable solutions — from paper weight (80-160gsm) to coating thickness (15-50µm), closure types to multi-color printing. Whether you need freezer-safe packaging for ice cream delivery, rain-resistant mailers for e-commerce, or grease-proof bags for bakery takeout, HUANCHEER delivers.

With export experience to over 30 countries, we meet international standards including REACH, RoHS, and EN13432 (for PLA-coated versions). Choose HUANCHEER for waterproof paper bags that protect your products and the planet.

• Superior Moisture Barrier: PE coating reduces water absorption from ≥30g/m² to ≤5g/m² — 6x more water-resistant than standard kraft paper
• Enhanced Physical Strength: Tear resistance increased by ~30%, burst strength improved by ~50% after PE lamination
• Wide Temperature Range: Performs reliably from -25°C (freezer) to 120°C (hot-fill) without brittleness or seal failure
• Heat Seal Compatible: Seals at 120-160°C for automated packing lines; creates airtight, tamper-evident closure
• Water Pressure Resistance: Withstands up to 5,000 Pa (ASTM D779) — proven protection against heavy rain and splashing
• Low MVTR: ≤5 g/m²/24h moisture vapor transmission rate preserves product freshness in humid environments
