Bulk Container Liners

Sea bulk container liners form a protective layer between your shipping container and goods you’re shipping. Bulk container liners reduce the risk of contamination and leaks, helping protect your reputation and your bottom line. Loading and unloading spouts help you save time and streamline the dry bulk shipping process.

Bulk Cargo Liners/Containment

Our Kratobag series sea bulk liners are ideal for dry bulk shipping. We offer four types of liners with a handful of optional features to help you find the right solution for your shipping needs.

Model: 5000 Full Liner

The Kratobag Series 5000 covers all six sides of your shipping container and features a wide opening for conveyor loading on the front bulkhead. The bottom spout makes unloading easy.They are commonly used for various meal exports.

The Kratobag Series 5000 is also available in a barless model. Because we’re able to eliminate the steel support bars, these sea bulk liners are more cost-effective.

The Kratobag Series 5100 is an open-top liner that covers five sides of your shipping container and features a wide opening for conveyor loading on the front bulkhead. The bottom spout makes unloading easy.

Like the Series 5000, we offer a barless version of the Kratobag Series 5100 to help you maximize cost efficiency.

6000 Wet-Hide Liner

The Kratobag Series Model: 6000 PE Liner is a polyethylene coated liner, the protective layer prevents and reduces leakages from the hides, caustic items or anything that may discharge a liquid. This liner can be combined with our Hypad for optimum protection and to meet regulations.

Temperature Stabilization

Our Temcore lineup is specially designed to create a reflective barrier to maintain stable temperatures inside your shipping container. If you’re shipping temperature-sensitive goods, Temcore liners offer the protection you need.

Temcore 40’ Full Liner

The Temcore 40’ Full Liner provides complete protection for 40’ shipping containers. These liners cover all six sides of your shipping container, keeping temperatures stable even when your cargo is exposed to extreme climates

Temcore 20’ Full Liner

The Temcore 20’ Full Liner is perfect for 20’ containers. Like our 40’ liner, the Temcore 20’ Full Liner covers all six sides to provide maximum protection against extreme heat and cold.

Temcore 40’ No Floor Liner

The Temcore 40’ HC No Floor Liner is very effective for rogue loading environments. You get coverage on five sides, everything but the floor. Your goods are protected from the most at-risk parts of a container that transfer heat.

Moisture Control

Moisture is a leading cause of cargo damage, but it’s also preventable. Our Kit Bond liners are engineered to minimize moisture inside your shipping container to prevent moisture damage and mold growth

Kit Bond Liners

Kit Bond liners are waterproof liners that protect your goods from damp floors and walls of shipping containers. Kit Bond liners are easy to install, and their high tensile strength means they don’t rip or tear and won’t cling to damp surfaces. These waterproof liners absorb moisture to help prevent mold and fungus growth inside shipping containers.

Kit Kraft Paper Lining

Kit Kraft paper lining is a simple way to keep your goods from contacting the container side walls while taking a fully sustainable approach. The Kit Kraft paper lining can be combined with Hybags, Hypads, and Hyblanket product lines to help reduce the risk of moisture to your goods.

Frequently Asked Questions

A shipping liner—also called a container liner or sea bulk liner—is a protective packaging solution that facilitates the transportation of bulk products. Made from high-quality food-grade materials, these container liner bags help agricultural, mineral, and chemical manufacturing industries move bulk goods with confidence.

When shipping dry bulk goods, it’s important to ensure cargo is isolated and protected from damaging external environmental factors. Container liner bags can transform a shipping container into a safe, reliable transport solution for bulk goods by creating an extra interior wall that protects the product.

Kratobag is a shipping liner solution that comes in several varieties, detailed below:
  • Kratobag Series 6000: This shipping liner features a large opening at its front and is fastened with a secure belt.
  • Kratobag Series 5100: This sea bulk liner is loaded through a top loading spout, then expelled through two spouts at the bottom after reaching its destination.
  • Kratobag Series 5000: This shipping liner features an entry top spout and is expelled through a spout at the bottom of the liner.
  • Kratobag Series 4000: This dry bulk container liner is loaded by a conveyor belt at the top of the front bulkhead, then emptied through a convenient bottom spout.
  • Kratobag Custom Series: We have created various liners for non-traditional goods as well. We will work to help you find the right solution for your application and based on your infrastructure for loading and unloading.

Sea bulk liners like Kratobag are effective shipping solutions for a variety of cargo types and products, including chemicals, petrochemicals, minerals, foods, seeds,and agricultural products.

In other words, container liners are ideal for any bulk product that “flows,” including powders, granules, and waste. Spouts at the bottom of most Kratobag liners make emptying containers as straightforward and efficient as filling them.

Shipping container liners are an ideal bulk shipping solution for several reasons.

High-quality container liner bags reduce the need for individual boxes and bags, decreasing overall shipping costs as well as the amount of single-use products needed to transport bulk goods. This change results in a smaller environmental footprint for logistics operations. Additionally, because the liner expands to match the exact dimensions of the container, there’s less wasted space in each container.

Kratobag shipping container liner bags also facilitate the safe and hygienic transportation of precious goods, protecting cargo from contamination by keeping out dust, dirt, moisture, and salt. Because shipping liners form an extra layer between the container and the products inside, they can even contribute to temperature control.

From an efficiency standpoint, container liner bags allow for better inbound and outbound logistics. One container liner bag is easier to install and transport than hundreds of bags or boxes, so less time is required to load and unload the container. Fixing a bulk container liner to the inside of a container takes mere minutes.

Finally, bulk liner bags can keep the contents of a sea bulk container from leaking, even if the container itself sustains damage during the voyage. When even one leaky container can cost thousands in lost products, fines, and clean-up fees, bulk bag liners offer peace of mind and financial security.

Shipping container liner bags are made of robust materials that provide a protective barrier between the wall of the shipping container and the goods inside. Using a dry bulk container liner is as simple as affixing the bag to the inside of an empty container. Two people can efficiently install a liner in minutes.

In most cases, there’s no need to add cardboard or other materials to prepare the container for the liner. As long as the container is free of debris that could puncture the bag, the container liner can go directly against the walls.

The container lining fits the exact dimensions of a shipping container so that organizations can take full advantage of the container space. Bulk bag liners can fit various shapes and sizes of shipping containers.

A bulkhead is included with shipping container liners. Bulkheads act as a fourth wall that keeps goods in place at the container’s opening, whether the door is open or closed. Most of the time, bulkheads are made from corrugated cardboard or another material and exist separately from the ocean container liner. However, with some Kratobag varieties, the bulkhead is built into the liner for added convenience and ease of install of bars.

Depending on the material, liners can be loaded or unloaded in various ways. Fine, lightweight products such as powders and sands can be packed into containers using gravity or pneumatic loading techniques. Larger or heavier bulk goods—including beans, grains, or pellets—can instead travel down a conveyor belt into the container liner. In all cases, the goods generally enter the liner through an opening near the top of the material.

Unloading is similarly dependent on the product inside the liner. Potential options for discharge include funneling the goods to a silo via a hose or relying on gravity to empty the contents into a pit or down a ramp.

Different loading methods may require different liner solutions, so choosing the right bulk container liner for the job is crucial.
