Frequently Asked Questions

Have a question? We’re here to help.

A container liner is a cost-effective and protective packaging solution that lines the interior of a shipping container. These bulk liners (often made from polyethylene, polypropylene, or PE film) form a barrier between the container walls and your cargo, preventing contamination, moisture infiltration, and potential damage. Because many container liners are food grade (and can even meet FDA requirements), they are safe for bulk products like grains, seeds, and pharmaceuticals.

Using container liners specifically designed for thermal regulation is often the most cost-effective way to insulate a shipping container. Thermal liners use reflective or insulating materials (such as LDPE or HDPE) to moderate extreme temperatures without requiring expensive permanent insulation. These liners can reduce shipping costs by protecting sensitive goods (e.g., food products) from temperature spikes in a budget-friendly manner.

“Sweating” occurs when moisture condenses on the interior walls. To prevent this:
  • Install container liners (like our Kit Bond or Temcore series) that act as a vapor barrier.
  • Ensure proper ventilation, especially if storing dry bulk goods.
  • Use desiccant packs or bulk container liners with advanced moisture barriers to reduce internal humidity.

Thermal container liners (such as the Temcore line) use reflective layers and insulated PE film or polyethylene to help stabilize internal temperatures. This easy installation approach effectively minimizes heat transfer from the sun-baked steel walls to your cargo, keeping the interior cooler—ideal for temperature-sensitive or flowable bulk products.

“Big Bag” or bulk bags (including FIBC options) can be paired with container liners to move large volumes of dry bulk items efficiently. They often have a spout for loading and unloading, making them a highly cost-effective choice for heavy or granular cargo. These liners can also be offered in barless designs (no steel bar support required), lowering materials usage and improving sustainability.

Thermal liners help regulate internal temperatures and are particularly beneficial for long hauls in extreme climates. Pricing depends on factors like:

  • Container size (20’ or 40’)
  • Liner material (e.g., HDPE, LDPE, or multi-layer PE film)
  • Special features (like barless or integrated bulkhead)

ISO shipping containers have standardized dimensions, making shipping container liners an ideal, snug fit. ISO liners:

  • Facilitate dry bulk transport with minimal waste
  • Support pneumatic or conveyor loading thanks to integrated spout systems
  • Maintain food grade standards and sustainability goals when crafted from quality, certified materials
    They can also be used across diverse industries (e.g., pharmaceuticals, minerals, food products) needing secure, hygienic, and protective transport.

The number of bulk liners per pallet depends on liner type, thickness, and any added features (like built-in bulkhead panels). Typically, dozens of folded liners can fit on a single pallet, optimizing storage and reducing shipping costs. We’ll provide specifics when you request a quote, as packaging can vary by design.

Thermal liners help regulate internal temperatures and are particularly beneficial for long hauls in extreme climates. Pricing depends on factors like:

  • Contamination Prevention: Keep products free from dust, rust, or other residues.
  • Reduced Packaging Waste: Replaces the need for multiple small bags or boxes.
  • Enhanced Hygiene: Ideal for food-grade, FDA-compliant, or sterile applications.
  • Time Savings: Quick loading and unloading through a spout or chute.
  • Barless Options: Eliminates the need for steel bar supports, boosting cost-effectiveness.
  • Sustainability: Many liners are reusable or recyclable, lowering environmental impact.

A shipping liner—also referred to as a container liner or sea bulk liner—is a flexible solution that transforms a standard shipping container into a custom transport module for bulk products. These liners are typically made from food-grade or FDA-approved materials (like woven polypropylene or polyethylene) to protect contents against contamination, moisture, and physical damage during transit.

Kratobag is a specialized brand of bulk container liners designed for dry bulk transport. Each Kratobag variant (e.g., 5000, 5100, 6000) offers specific features such as multiple spout openings, barless support, or built-in bulkhead panels. Kratobag liner bags handle everything from powders to granular minerals and can be customized for unique loading/unloading configurations.

Shipping container liners accommodate a wide range of flowable or dry bulk items:
  • Agricultural commodities (grains, seeds, powders)
  • Chemicals and minerals
  • Pharmaceuticals
  • Food products needing food grade packaging

Any product that can flow under gravity or pneumatic pressure is an ideal candidate for container liner bags.

  • Bulk Packaging: More efficient than numerous small sacks or boxes.
  • Leak Protection: Built-in bulkhead or barless designs keep cargo secure, even if the container is damaged.
  • Sustainability: High-quality materials (including certain recyclable or reusable films) reduce environmental impact.
  • High Capacity: Optimizes the full internal dimensions of the container.
  • Moisture Control: Some liners (e.g., thermal liners) also offer insulation or specialized coatings to minimize condensation.

A shipping liner is installed against the walls of an empty container, creating a secure “bag” that conforms to the container’s shape. Features include:

  • Bulkhead: A detachable or integrated panel that holds the product inside when doors are open.
  • Spouts: For loading/unloading dry bulk cargo via conveyor or pneumatic systems.
  • Easy Installation: Generally, two people can set up the liner in minutes, as no extensive modifications are needed.

Bulk container liners support various loading/unloading methods:

  • Gravity or conveyor belt (ideal for grains, seeds, pellets)
  • Pneumatic (especially with fine powders or dust)
  • Spout or hose feed (common for top loading and bottom discharge) Once the product arrives, the bottom spout or front opening is used to direct the cargo into a receiving system like a silo, pit, or ramp.

Most bulk liners are made from woven polypropylene or multi-layer PE film like LDPE or HDPE. These materials are strong, flexible, and resistant to tearing. Some liners (like the Kratobag barless model) do not require additional steel bar reinforcements. For additional moisture or thermal protection, specialized coatings or reflective layers can be added.

Common sizes align with ISO container dimensions (20’, 40’, or 40’ high cube). Liners span the full interior to cover walls, floor, and ceiling, or can be a partial fit if no floor coverage is needed. Custom dimensions exist for unique shipping needs, ensuring minimal wasted space for dry bulk cargo or food-grade loads.

Repeating this important point: Installing thermal container liners is typically the fastest, simplest, and most cost-effective method. Reflective or insulated bulk liners reduce radiant heat transfer and prevent condensation without the higher labor and material expenses of traditional insulation systems.

  • Use container liners (often with vapor barriers) to block external moisture.
  • Employ desiccants or ventilation to curb humidity.
  • Maintain a stable internal temperature, potentially with thermal or reflective liners. By sealing the walls with the right liner and controlling airflow, you can effectively curb sweating.

Thermal or reflective shipping container liners are designed to maintain lower temperatures. They often incorporate polyethylene or PE film layers to reflect radiant heat away from the container interior. Additional strategies like roof coatings, external shading, or ventilation further enhance cooling effects.

  • Install bulk liners with moisture barriers (e.g., laminated or coated materials).
  • Add desiccant packs or other dehumidifiers.
  • Consider Kit Kraft paper lining for an extra protective layer to absorb dampness.
  • Keep the container well-sealed and free from leaks, ensuring sustainability in your shipping processes by reducing cargo spoilage.

  • Use insulating container liners or “no-floor” designs to combat ground-based temperature fluctuations.
  • Ensure the interior is clean and free from moisture before loading.
  • For flowable or bulk products, choose liners with a moisture-resistant coating or sealed seams.

  • Use specialized container liners designed to block external cold or humidity.
  • Combine with desiccants if shipping in extremely humid or cold climates.
  • Maintain sustainability by selecting food-grade or FDA-approved liners if you’re transporting sensitive items like food products or pharmaceuticals.
  • Monitor interior conditions to adjust humidity controls as necessary.

  • Employ dry bulk or multi-layer bulk liners to create a tight seal.
  • Ensure minimal exposure to outside, damp air by closing doors promptly.
  • Consider additional moisture control products (like sorbents or ventilation).
  • Regularly check for damage to the liner or container shell to prevent breaches.
