Among the primary capabilities of FIBCs is protecting against the ill effects of moisture. Hence, it is important that you also know the roles of waterproofing and water resistance for these containers. Are you curious about their differences? Discover these insights in this comparative guide that will tackle the following:
– First level: Coated/laminated fabric for water resistance
– Second level: Using a PE liner for waterproofing
– Third level: Sift-proofing seams to stop moisture creep
Let’s get to the discussion!
Understanding the ideal moisture barrier of FIBCs is understanding the three magnificent levels involved:
Generally speaking, coated and laminated textiles or fabrics typically consist of a textile substrate, or a woven textile, otherwise knitted or non-woven.
This fabric is capable of providing the slightest moisture barrier by adding in a thin polipropileno film to the woven material. With this layer, water vapor is significantly reduced and moisture kept at bay, such as light rain or humidity.
Their waterproof quality isn’t the best, though, since this level of protection is ideal for less sensitive goods during transport and storage.
PE liners, or polyethylenes, are materials made of plastic, used thoroughly with FIBCs. In the most general sense, these liners are used to protect the content of the container from contamination or moisture, also to protect the container itself from whatever it holds.
This second level of moisture protection uses the liner inside the FIBC to create the most reliable waterproof barrier for the most sensitive products. They are usually 60 to 120 microns thick, thicker than the first-level material, preventing moisture, vapor, or fine powder from getting in or escaping, making them ideal for hygroscopic, food, or chemical materials that require complete moisture isolation.
The creep of moisture, despite the presence of the first and second moisture protection levels, is a big problem. The solution here: sift-proof the seams.
Sift-proofing seams in your FIBCs prevents moisture from creeping into fine powders and particles. Since the moment moisture creeps in, the quality of the materials is affected.
To achieve the perfect sift-proofing, holes are stitched by incorporating filler cords across the sewing process. Such seams effectively block the creeping, therefore the loss of products, too, such as fine, flowable material like sand, chemicals, minerals, and powders that may flow out due to moisture.
Also, there are various options here, such as single- to triple sift-proofing, or adding felt for maximum protection, ensuring the integrity of products and reducing contamination and wastage during storage and transport.
Actually, there isn’t also a one-size-fits-all for this, talking about which level of protection is perfect. These moisture protection ranges are categorized into three different levels, and are according to the usage. Here’s a closer look.
So, it really depends on your intended use.
