IBC lined bag

Structural Components

• IBC Liquid Bag Types: Available as single-layer or multi-layer inner liner bags.
• Multi-layer Inner Liner Bags: Typically made of multiple layers of different plastic films. For example, the outer layer may use polyethylene (PE) with sufficient strength and wear resistance for protection, while the inner layer is selected based on the liquid’s properties—either food-grade materials meeting hygiene standards or chemically resistant materials—to ensure the quality of the contained liquid remains unaffected.
• Additional Components: Generally equipped with inlet/outlet valves and vents to facilitate filling, discharging, and balancing internal/external pressure during transportation.

Specifications and Capacity

Common Specifications

The IBC liquid bag comes in various sizes, with the most common ones designed to fit standard IBC frames. Its overall dimensions are compatible with typical IBC metal frames, allowing it to be placed within the frame for protection and support during handling and transport. It can also be placed in custom cardboard boxes or foldable plastic crates, using these as support structures for long-distance transportation of large volumes of liquid cargo.

Capacity Range

The capacity of IBC liquid bags typically ranges from a few hundred liters to over a thousand liters, with common capacities falling between 500 and 1,000 liters. Different capacity options cater to varying customer needs, from small-batch specialty product transport to large-scale distribution of regular liquid goods.

Advantages

Cost-Effectiveness

Compared to traditional rigid containers (e.g., metal barrels, plastic drums) or large fixed tanks, IBC liquid bags have a lower procurement cost. Their foldable design and compact storage reduce space requirements, saving significant transportation and warehousing costs during return trips or storage of empty bags. Overall, they effectively lower the packaging and logistics expenses for liquid goods.

Flexibility and Convenience

With excellent flexibility, IBC liquid bags adapt to various outer packaging containers, such as IBC metal frames. The filling and discharging processes are straightforward, completed quickly using supporting pipes and pumps, reducing manual labor complexity and time costs while improving logistics turnover efficiency.

Environmental Performance

Most IBC liquid bags are made from recyclable plastic materials. When processed through proper recycling channels after use, they have a relatively low environmental impact, aligning with trends in eco-friendly logistics and green packaging, and supporting businesses in achieving sustainability goals.

Usage Limitation

We recommend single-use for IBC liquid bags, which eliminates the cleaning costs associated with steel barrels and traditional IBC containers.

Applicable Scenarios

IBC liquid bags are widely used in industries requiring storage and transportation of liquid products:

• Chemical Industry: Packaging and transporting various liquid chemical raw materials.
• Food Industry: Commonly used for liquids like edible oils, beverages, and dairy products, ensuring hygiene and quality during transport.
• Pharmaceutical Industry: Utilized for some liquid pharmaceuticals or raw materials.

Food and Beverage Industry

Used to transport fruit juices, wines, edible oils, and other liquid foods, ensuring food safety and hygiene while enabling efficient distribution from production sites to markets. The bag’s material can be selected to meet food-grade standards, avoiding any adverse impact on food quality.

Chemical Industry

For non-hazardous chemical liquid raw materials and additives, IBC liquid bags are a common packaging and transport solution. They meet corrosion resistance requirements while facilitating convenient raw material allocation and transportation between chemical companies.

Pharmaceutical Industry (Partially Applicable)

In transporting non-injectable pharmaceutical liquids with less stringent packaging demands, IBC liquid bags can be used if their materials comply with relevant medical packaging hygiene standards. They offer a cost-effective and convenient option for bulk transport of items like topical disinfectants.

Structure

• Shape: Typically cubic or rectangular-cubic to match the internal shape of an IBC drum, ensuring a snug fit and efficient use of container space.
• Interfaces:
  • Upper Valve: Used for filling liquids, typically featuring a sealed snap-on connection to the IBC drum’s top opening, with single or double-layer sealing structures.
  • Lower Valve: Used for discharging liquids, also featuring a sealed snap-on connection to the IBC drum’s bottom outlet, with robust sealing to prevent leakage.

Advantages

• Pollution Prevention: Acts as a barrier between bulk materials and the IBC interior, preventing dust, moisture, and other contaminants from entering, ensuring the purity and quality of stored and transported liquids.
• Improved Cleanliness: Helps maintain IBC cleanliness, reducing the need for frequent cleaning and the risk of cross-contamination between different materials, saving time and cleaning costs.
• Reduced Waste: Using IBC liner bags minimizes the need for thorough IBC cleaning after each use, reducing water and detergent consumption and waste generation, aligning with environmental principles.
• Easy Dispensing: Designed with user-friendly nozzles or outlets, simplifying the liquid dispensing process and minimizing product waste.
• Versatility: Suitable for packaging various liquid materials across industries like chemicals, food, pharmaceuticals, coatings, and oils.

Technological Innovations

New Structural Design

IBC liner bags are made from multi-layer plastic films joined via heat sealing. The rigid upper valve component is mounted at the center of the bag’s top, addressing issues with traditional liner bags during installation and use. The design is sturdy, practical, and fits well with the container, facilitating automated production processes.

Cleaning-Free Interface Components

To address the challenge of cleaning IBC drums and valves, the IBC drum valve uses a cleaning-free lower interface component for the liner bag. During discharge, the hose extends into the valve pipeline, fitting tightly against it. This ensures efficient filling while keeping the valve clean, reducing costs and environmental pollution from valve cleaning.
