Description
PE Coated Kraft Paper Bag 120-160gsm Rain Resistant Waterproof Honeycomb Packing Paper
PE-Coated Waterproof Kraft Paper Bag 120-160gsm - Rain-Resistant & Freezer-Safe for E-Commerce, Cold Chain & Outdoor Shipping - Fully Recyclable

Engineered for harsh shipping conditions, our PE-coated waterproof kraft paper bag combines the natural eco-friendliness of kraft paper with a high-performance polyethylene (PE) lamination layer on the inner surface. The 120-160gsm total weight (80g kraft base + 40-80g PE coating) delivers exceptional moisture resistance — with static water absorption reduced to ≤5 g/m² (compared to ≥30 g/m² for standard kraft) — while maintaining the lightweight, flexible properties of paper.

Available with multiple closure options — self-adhesive peel-and-seal for tamper-evident shipping, heat-sealable for automated packing lines, or zipper closure for re-sealable retail packaging — this bag adapts to your workflow. The heat-seal compatibility (120-160°C) ensures airtight closure, preventing moisture ingress during transit. Fully recyclable and FSC-certified, it offers a sustainable alternative to plastic mailers and polyethylene bags. Custom sizes, colors, and up to 6-color printing available to align with your brand identity.

Company Introduction

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.

Key Features
  • 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
  • Multiple Closure Options: Self-adhesive peel-and-seal / heat-sealable / tuck-flap / zipper (re-sealable)
  • Fully Recyclable: PE-coated kraft paper can be recycled in standard paper streams (PE content ≤20%)
  • Customizable: Sizes from 8×12cm to 50×70cm; up to 6-color printing; Pantone color matching; logo embossing
  • Food Contact Safe: FDA 21 CFR 176.170 compliant for direct dry food contact
  • Certifications: FSC-certified, RoHS, REACH (PE-coated version); PLA-coated version available for 100% biodegradability

Frequently Asked Questions
Q1: Is the PE coating on this bag fully waterproof?
A: The PE coating provides IPX4 to IPX6-level water resistance, meaning it can withstand splashing water and up to 4 hours of heavy rain exposure without moisture penetrating to the contents. However, it is not designed for submersion. For complete waterproofing (submersion-proof), we offer double-layer bags with internal PE liner.
Q2: Can this bag be used for frozen food or cold chain shipping?
A: Yes, the PE-coated kraft paper remains flexible and non-brittle down to -25°C, making it suitable for freezer storage and refrigerated transport. The moisture barrier prevents freezer burn and ice crystal formation on the bag surface. Many customers use these bags for ice cream, frozen meals, and cold-pack medications.
Q3: Is the bag recyclable? Can PE-coated paper be recycled?
A: Yes, PE-coated kraft paper is widely recyclable in standard paper recycling streams when the PE content is ≤20% (our standard coating is 15-20%). The coating separates from the paper fibers during the pulping process. For customers requiring 100% biodegradable packaging, we offer PLA-coated versions that are fully compostable within 180 days under industrial conditions.
Q4: What is the difference between single-side and double-side PE coating?
A: Single-side coating (PE on the inner surface) provides moisture protection for the contents while keeping the outer kraft paper surface for printing and a natural paper feel. Double-side coating (PE on both sides) offers maximum water resistance for extremely wet environments but may affect printing adhesion and recyclability slightly.
Q5: Can this bag be heat-sealed? What equipment is required?
A: Yes, the PE coating is heat-sealable at 120-160°C. It is compatible with continuous band sealers, impulse heat sealers, and automatic form-fill-seal (FFS) packing lines. Heat sealing creates a stronger, more tamper-evident closure than self-adhesive strips, ideal for automated high-volume packing operations.
Q6: What is the recommended weight capacity for this bag?
A: For 120gsm PE-coated bags, we recommend up to 3-5kg. For 160gsm, up to 5-8kg. For heavier loads (up to 20kg), we recommend our double-layer construction with reinforced bottom gusset. The PE coating also increases tear strength by approximately 30%, providing better durability for heavier contents.
Q7: Can I get a custom size larger than 50×70cm?
A: Yes, we can produce custom sizes up to 70×100cm for single-layer PE-coated bags with MOQ 10,000 pieces. For double-layer construction, maximum size is 55×70cm due to material handling constraints.
Q8: Is this bag food-safe for direct contact with food?
A: Yes, our PE-coated kraft paper is FDA 21 CFR 176.170 compliant for direct contact with dry food products (e.g., bread, pastries, nuts, candy, coffee beans, pet treats). The PE layer acts as a barrier preventing oil and moisture migration. For wet or high-fat foods, we recommend our double-PE-coated version.
Q9: Does the PE coating affect printing quality?
A: Printing is applied to the uncoated kraft paper surface (outer side) before or after lamination, depending on the printing method. Flexo printing achieves excellent color vibrancy and detail up to 6 colors. The natural kraft texture may absorb more ink than coated paper, resulting in a matte, organic finish that many brands prefer for eco-conscious positioning.
Q10: What certifications do you offer for export to Europe?
A: Our standard PE-coated bags are REACH and RoHS compliant. For customers requiring EN13432 compostability certification, we offer PLA-coated (polylactic acid) biodegradable versions that are 100% compostable. FSC certification for the kraft paper base is also available. We can provide test reports upon request.
