Heavy Duty PE Liner Bag – Custom Food Grade & Anti-Static Inner Liner for FIBCs

This Heavy-duty Thickened PE Liner Bag is manufactured using LLDPE, LDPE, or HDPE as its core material. It is specifically engineered to meet the stringent requirements of industrial applications involving heavy-duty, corrosive materials, providing essential protection against moisture, leakage, corrosion, and static electricity. It is primarily designed to serve as a compatible inner liner for FIBCs, intermediate bulk containers (IBCs), and drum liners.

Engineered for heavy-duty industrial storage and transportation, this product features robust durability and reusability. It is the ideal protective packaging solution for demanding sectors like chemicals, metallurgy, and building materials. As a high-performance industrial container liner, it ensures consistent material quality while significantly reducing packaging waste.

 

  Core Manufacturing Process & Technical Specs

Material Selection & Blending: We select 100% virgin PE pellets as the base material and precisely incorporate functional additives (such as anti-static agents and weather-resistant masterbatches) based on specific usage requirements. These components are thoroughly melted and blended at high temperatures to ensure uniform dispersion, guaranteeing the protective performance of the liner bag from the very source.

Process Step Critical Control Parameters (Strictly Monitored) Quality Outcome
Precision Blown Film Molding
  • Extrusion Temp: Strictly controlled at 160–220°C.
  • Blow-up Ratio (BUR): Maintained at 1.5–3.0.
  • Speed Matching: Take-off speed and extrusion rate are synchronously matched.
 Produces a base film with uniform thickness and minimal gauge variation, ensuring consistent bag strength.
High-Strength Heat Sealing
  • Temperature: 120–200°C.
  • Pressure: 0.2–0.5 MPa.
  • Dwell Time: 0.5–2 seconds.
 Achieves seal strength of ≥5 N/15mm, completely eliminating any risk of material leakage.
Custom Cutting & Rigorous Inspection
  • Custom Fit: Cut to exact dimensions of FIBCs/IBCs.
  • Thickness Tolerance: Controlled within ±5% to ±10%.
 Each batch is tested for sealing performance and tensile strength. Products are only released after meeting all metrics.

 

Industry Applications

Versatile packaging solutions for various sectors

Chemical Industry Packaging: Designed for corrosive or leak-prone materials such as acid/alkali solutions, resin powders, paints, and inks. Its exceptional corrosion resistance and leak-proof performance effectively protect transport containers, enabling reuse and significantly reducing secondary contamination costs.

 

Construction & Plastics Industries: Acting as a premium inner liner for FIBCs (Big Bags), it is suitable for materials such as plastic pellets, calcium carbonate powder, and cement additives. Featuring superior moisture/oxygen barrier properties and puncture resistance, it prevents materials from caking or degrading, ensuring raw material stability.
