Industry-specific vocabulary can often be a source of confusion, and the bulk bag industry is no exception. At Six Star Bulk Bag, we frequently receive questions about terminology. For instance, bulk bags are also known as FIBCs (Flexible Intermediate Bulk Containers), jumbo bags, big bags, and super sacks. This variety in terminology can cause confusion, especially when it comes to terms like stevedore straps. So, what exactly are stevedore straps?
Stevedore Straps Explained
Stevedore straps are additional straps that attach to the standard polypropylene straps sewn into an FIBC. These straps can be purchased separately or with the bulk bags. They loop through the existing lifting loops to provide additional lifting options, making them particularly useful for forklifts. These straps create easy access points for forklifts to move the bags within a facility, which is why they are commonly used in warehouses where FIBCs are handled frequently. Stevedore straps are also known as ‘loading belts’.
Types of Stevedore Straps
There are three main types of stevedore straps commonly used:
Standard (Supporting) Stevedore Straps: They involve four individual straps that attach to each of the straps sewn into the bag. They are useful when the standard straps are not long enough or when extra clearance from the top is needed.
Double Stevedore Straps (Double Loading Belt): This setup uses two longer straps, each looped through two of the straps sewn into the bag. It is ideal for use with forklifts or cranes, as it simplifies the process of inserting the forklift's arms or the crane's hook for lifting.
Single Stevedore Strap (Single Loading Belt): A single strap loops through all four of the bag's sewn-in straps, offering a simple and easy lifting option. This setup is common in facilities using forklifts, as it facilitates easy movement of the FIBC.
Benefits of Stevedore Straps
Using stevedore straps with FIBC bulk bags enhances efficiency and ensures safety. These straps provide a secure and reliable way to move, store, and transport large bulk bags. They help maintain the stability and security of the bags during transport and storage, reducing the risk of accidents, injuries, and damage. It is crucial to install the straps correctly to prevent them from becoming loose or failing during transport. Regular inspection is also necessary to ensure they are in good condition and not worn or damaged.
Should You Use Stevedore Straps with Your FIBCs?
The decision to use stevedore straps depends on your product, application, and facility operations. If your facility frequently uses forklifts, these straps can make handling bulk bags more efficient. However, it's important to note that FIBCs with stevedore straps generally cost more than those without. Despite the higher cost, the efficiency gains in facilities with high forklift use often make stevedore straps a worthwhile investment.
Bulk bags, or FIBCs (Flexible Intermediate Bulk Containers), are highly versatile containers used for storing and transporting various products. However, a common question is, "Are FIBCs watertight or waterproof?" Here, we address this query and offer potential solutions.
Are Bulk Bags Watertight or Waterproof?
FIBCs are not inherently watertight or waterproof. Made from woven polypropylene, the fabric is not designed to fully prevent water ingress or egress. Some bags have a polypropylene laminate coating on the inside, outside, or both, which acts as a moisture barrier. While this reduces fine material leakage, it does not make the bags completely waterproof.
Can You Make Bulk Bags Watertight?
Several types of closures can enhance a bulk bag's water resistance. The most common is the drawstring top, which uses a rope or string to tighten the bag, keeping liquids out but being somewhat difficult to manage. Other options include flap tops, which cover the opening with fabric secured by snaps or buttons, and valve tops, which use a rubber or plastic valve.
For bottom closures, the spout is standard, allowing for controlled discharge. Other options include gusseted bottoms, which help the bag stay upright, and tie closures using cloth or string.
Can You Make Bulk Bags Waterproof?
Though not completely waterproof, several methods can improve moisture protection for FIBCs. Using polyethylene liners, which are thin plastic inserts fitting inside the bulk bag, adds a layer of protection. These can be separate liners or custom pre-lined bulk bags. Form-fit liners, designed to fit snugly inside, are ideal for transporting liquids but still do not make the bag entirely waterproof.
Understanding these options allows you to better protect your products during storage and transportation.
At Six Star Bulk Bag, we frequently receive questions about the construction of Flexible Intermediate Bulk Containers (FIBCs), commonly known as bulk bags, and how to choose the right type. Our goal is to ensure our customers select the best bag for their specific product and application. The decision often hinges on whether the bag is coated or uncoated. Let’s explore the differences between these two types and their common uses.
What is an Uncoated FIBC?
Uncoated FIBCs are made by weaving together strands of polypropylene. Due to this woven construction, fine materials may seep through the weave or sew lines. For instance, if you pack a powder in an uncoated bag and hit the side, you might see a cloud of product escape. While this is acceptable for some applications, it is not for others. Additionally, the weave allows air and moisture to pass more easily through the bag, which can impact the stored product.
Common uses for uncoated bags:
-
Transporting/storing specific types of food grade and non-food grade products.
-
Transporting/sorting granular products the size of rice grains or larger, such as beans, grain, popcorn, and seed.
-
Transporting products that need to breathe.
What is a Coated FIBC?
Coated FIBCs are similar to uncoated bags but with an added layer of polypropylene film that seals the small gaps in the weave. This film can be applied to either the inside or outside of the bag, with the inside being more common to prevent powders from getting stuck in the weave during discharge. To determine if a bag is coated, press the weave together; if it does not spread apart, the bag is likely coated.
Benefits of coated bags:
-
Provides additional protection from contaminants like dust, moisture, and dirt.
-
Acts as a moisture barrier, preventing fine powders from escaping when the bag is hit.
-
Useful for packing small granular or powdered products.
Common uses for coated bags:
-
When a moisture barrier is needed.
-
Transporting dry flowable products in powder, crystal, granule, or flake form, such as cement, detergents, flour, salt, fine minerals, sand, and sugar.
-
Sometimes used with a poly liner for extra protection.
When Coated Bulk Bags Are Not Enough
Coating acts as a moisture barrier but does not make the bag waterproof. For extremely fine granular products and powders, additional features like sift-proof seams may be required to prevent the product from escaping through sew holes. While this adds to the cost, it ensures better containment. In cases where even more protection is needed, bags with polyethylene liners are recommended, such as for powdered sugar.
Conclusion
Choosing between coated and uncoated FIBCs depends on the specific requirements of your product and application. Coated bags offer additional protection and are suitable for finer materials that need moisture barriers. Uncoated bags, on the other hand, are ideal for products that require breathability.

When researching Flexible Intermediate Bulk Containers (FIBCs) beyond Six Star Bulk Bag, you might come across varying information about UV stabilization. This feature often leads to confusion due to the abundance of misinformation. Here, we clarify what UV stabilization means, how it impacts bulk bags, and the safety of storing these bags outside.
FIBCs and UV Degradation
You may have heard claims that FIBCs are “UV safe” or “UV resistant.” While partially true, it doesn't imply complete immunity to UV degradation. Bulk bags can resist UV rays to some extent, but prolonged sun exposure will eventually lead to their degradation. All FIBCs have an hour rating that indicates their UV exposure limit. At Six Star Bulk Bag, we strongly advise against storing bags outside due to the risks associated with prolonged sun exposure.
UV degradation happens when bags are exposed to UV rays over extended periods. All synthetic polymers, including the polypropylene used in FIBCs, deteriorate under UV exposure. UV rays break down the chemical bonds in polypropylene, creating free radicals that weaken the material. This degradation can cause the bags to crack, become unstable, and ultimately fail, posing significant risks of injury or death.
Polymer Stabilizers
If outdoor storage isn't recommended, why are FIBCs sometimes labeled as “UV safe”? This confusion arises because FIBCs are manufactured with polymer stabilizers. These stabilizers are chemical additives mixed with polypropylene during production to prevent material degradation. They absorb UV rays and dissipate them as low-level heat, enhancing the bags' UV resistance. However, these stabilizers break down over time, so knowing your bag’s UV exposure rating, usually measured in hours, is crucial.
Why This Matters
Safety is paramount at Six Star Bulk Bag. We prioritize helping customers find the right bag for their needs, offering safe handling tips, and guiding them through complex requirements, such as food-grade standards. Without polymer stabilizers, UV exposure would significantly degrade the bags, making them unsafe. Even with these stabilizers, there are limits to how long a bag can safely be exposed to UV rays.
Our FIBCs comply with the ISO 21898 Standard, recommending that bag exposure to UV rays should not exceed 200 hours. This limit can vary based on location; for instance, the sun’s intensity in Arizona differs significantly from the often cloudy conditions in Washington state, affecting how quickly a bag degrades. Given these variables, we never recommend outdoor storage. If unavoidable, consult your supplier for specific guidance regarding your use case.
Conclusion
Understanding UV stabilization is crucial for the safe use of FIBCs. While polymer stabilizers provide some protection against UV rays, they are not foolproof, and prolonged exposure can still lead to degradation. Always consider your environment and consult with suppliers to ensure your FIBCs are used safely and effectively. At Six Star Bulk Bag, we are committed to providing reliable, safe bulk bag solutions tailored to your needs.

For various products and applications, specialty bags like coated FIBCs and FIBCs with pre-installed liners are necessary for safe use. However, determining when to use a lined bag versus a coated bag can be challenging. At Six Star Bulk Bag, we frequently address this question and aim to clarify it in this section.
FIBC Liners
Poly liners are plastic inserts placed inside FIBCs to prevent leaks. They are particularly useful for storing and transporting fine powders or when an extra moisture barrier is required. These liners are especially beneficial in the food and pharmaceutical industries. When combined with a multi-use bag (6:1 safety ratio), the liners can be easily removed, discarded, and replaced, allowing the bulk bag to be reused. This reusability is one of the main advantages of poly liners over bulk bags with pre-installed liners.
Lined Bulk Bags
While companies can purchase and insert poly liners into any FIBC, they can also buy bags with pre-installed liners. These lined bulk bags offer a variety of options, making them suitable for a wide range of products and applications. However, the main disadvantage is that these liners are usually sewn into the seams or tabbed to the bag’s material, making them non-removable. This limits the flexibility for reuse compared to removable poly liners.
Coated Bulk Bags
Coated FIBCs are constructed similarly to standard FIBCs but with an added polypropylene film to the fabric before the bag is sewn together. This film seals the small gaps in the poly weaves and can be applied inside or outside the bag. Inside coating is more common as it prevents powders from sticking in the weave during discharge. Identifying a coated bag can be tricky if you're not familiar with FIBCs. The easiest method is to press the weave together; if it doesn’t spread apart, the bag is likely coated.
The primary benefit of a coated bag is the added protection it offers against contaminants such as dust, moisture, and dirt. This makes coated bags ideal for environments where these factors are a concern.
Common uses for coated bags include:
-
Transporting dry flowable products in powder, crystal, granule, or flake form, such as cement, detergents, flour, salt, fine minerals like carbon black, sand, and sugar.
-
Using a poly liner along with a coated bag for additional protection.
When to Use Liner, Coated, or Lined Bulk Bags
Choosing between a poly liner, lined bag, and coated bag depends on your product and application. Coated bags offer less protection against contamination than lined bags and poly liners but are more economical. For enhanced protection, especially with fine powders, poly liners, and pre-lined bags are the best options due to the potential for fine powders to seep through woven polypropylene.
When deciding between removable poly liners and pre-installed liners, consider whether you will be reusing the bags and if you need a specialty liner (such as aluminum foil, lay-flat, baffle, or form fit). Removable liners typically come in standard polypropylene, so if you need a specialty liner, a pre-lined bag is the best choice. For reusability, removable poly liners are ideal as they can be replaced, allowing the FIBC to be used for different products or applications. Simply remove the used liner, discard it, and insert a new one to prepare the bag for its next use.

Polyethylene liners, often referred to as poly liners, are flexible plastic liners designed to fit inside flexible intermediate bulk containers (FIBCs or bulk bags). These liners provide an extra protective layer for both the product and the bulk bag, making them highly useful in a variety of industries and applications.
Using Poly Liners with Chemicals
FIBCs are generally resistant to many types of chemicals. However, in some cases, additional protection is necessary. Using poly liners with bulk bags prevents chemicals from seeping through the fabric weave and seams of the FIBC. It also protects the woven polypropylene from chemical contact, which can increase wear and tear on the bag.
Using Polyethylene Liners with Fine Powders
Flexible intermediate bulk containers are made of woven polypropylene, creating a strong, flexible, and lightweight material. However, this weave can pose problems when handling fine materials. Fine powders can leak through the bag during transport, maneuvering, and filling. Poly liners are essential in these cases to prevent fine powders from escaping through the body and seams of the bag. They should be tied at the top after filling to ensure the material is contained.
Using with Sensitive Materials
Polyethylene liners not only protect the FIBC but also provide additional protection for the contents. In industries where contamination is unacceptable, such as food and pharmaceuticals, poly liners prevent moisture, dust, and other contaminants from reaching the materials inside the FIBC.
Common Industry Applications
Polyethylene liners can be used across various industries, depending on the material being stored or transported. Some key industries include:
