Flexible Bag Solutions for Heavy Liquids

Professional BIB Packaging Solutions

Viscosity-Optimized Discharge Systems

These flexible bag solutions are specifically designed to manage the high density and high viscosity of heavy liquids (e.g., purees, thick oils, gels). Key features include wide-bore, zero-retention dispensing valves (typically 2 or 3 inch diameter) and internal bag geometry optimized for efficient pump suction or gravity flow. The film material is highly flexible yet tear-resistant, promoting maximum yield (> 99% product evacuation) by conforming to the shape of the outer container during emptying.

Efficient Handling of High-Value Viscous Media

LPS offers customized flexible packaging that overcomes the challenges of storing and dispensing thick or heavy liquid products. Our solutions minimize the product waste traditionally associated with rigid containers by ensuring near-total contents recovery, providing significant cost savings for high-value viscous materials.

Specification Details

Viscosity RatingUp to 50,000 cP (Centipoise) Handled
Discharge Aperture2 to 3 Inch Wide-Bore Valve
Evacuation Efficiency>99% (Aided by pump or gravity)
Container FormatCube-shaped or Rectangular IBC Liners, Drum Liners
Compatible Liquid TypesHeavy syrups, fruit pulps, thick sauces, chocolate compounds, high-viscosity oils, gels.
  • Q: Do these bags require special pumps for dispensing?
  • A: While they can use standard pumps, highly viscous liquids benefit from positive displacement pumps (e.g., piston or diaphragm pumps) connected directly to the wide-bore fitment for efficient and consistent flow.
  • Q: How do you prevent the bag from tearing when filled with heavy liquid?
  • A: We use a combination of high-density, multi-layer PE films and reinforce the corner seals to manage the high hydrostatic pressure exerted by dense, heavy liquids.

Structural Components

  • Liner: Heavy-duty PE film with custom geometry.
  • Wide-Bore Valve: Food-grade PP or HDPE valve with quick-seal cap.
  • Outer Casing: Corrugated bulk box or rigid plastic IBC tote.
  • Airlift Port: Optional dedicated port for air assist or venting during high-speed fill/discharge.

Material & Assembly Process

Materials: High-melt-strength LDPE or LLDPE to handle high temperatures during filling and sealing, often with Nylon for structural reinforcement. Process utilizes Automated Bulk Bag Forming and Filling with specialized equipment designed for gentle handling of high-viscosity materials.
