More about our Polypropylene Bags

Best Priced Polypropylene Bags on Sale in Gauteng

What are Polypropylene Bags?

These Bags, because of the strong material that it is manufactured (woven) with, is a very strong way of transporting and storing various products inside of the strong aesthetic clean bags. The Thickness of the manufacturing "woven" material is measured in GSM (grams per square meter). The heavier the product inside the bags or the more robust structure of the product that is inserted in the bags determines the thickness (gsm) of the material that it is manufactured of land needs to be manufactured of.

The testing of the Polypropylene (Polyprop) material is performed in an up to standard testing facility weighing each time the exact same size of Polyprop material. The different weights of the exact same size material samples indicates the thickness, in other words, the GSM of the Polyprop material. Polypropylene material can also be UV treated which will enable the bags to last longer in direct sunlight where the bag material is exposed to UV damage.

In the case where a very fine product is being inserted inside of the woven (Polyprop) bag and the product itself may be filtering through the "woven"  material the solution to stop the product from filtering through will be to laminate (treat) the Polyprop Bag material. Lamination of the Polyprop Bag material is where the "woven" Polyprop material is covered with a plastic layer and the layer is attached to the "woven" material with a heat process which prevents any product to filter through the bag itself.

Polypropylene (Polyprop) Bags are suited for the printing of customer logos of any kind of design or print which the customer would prefer. There are two methods of labeling a bag with a logo or print and they are either normal printing or BOPP printing. Normal printing is where normal ink is applied to a raw Polypropylene Bag without any additional plastic layer and so on. Bags can in both types of printing be printed on the front and on the back / reverse side of the bag.

BOPP printing is where the logo/print is printed on a plastic layer and again with a heat sealing process attached permanently to the Polyprop Bag. the advantage with the BOPP printing is that the quality of the logo/print is very high standard and almost the same quality of a real live photo finish. An example of BOPP method printing is the dog food bags with the dog in front looking like a real dog itself in photo quality. The disadvantage of the BOPP method of printing is that this method is much more expensive than the plain or conventional method.

The plain/conventional printing of Polypropylene "woven" Bags is the most cost efficient method of printing with the quality of the print not of that high quality as BOPP method of printing. We normally suggest to customers just starting a new business to start using the plain/conventional method which is not that much expensive and on a later stage as their finances grow to consider the BOPP printing method which will also help the marketing of their product through the better quality logo on their packaging.

The Polypropylene Bags on sale is manufactured in different sizes to contain different weights of products inside of the bags which is determined by the customer's needs. The different weights for which the bags are being manufactured varies from 5kg and goes up to 2000kg weight capacity per bag.

Our smaller size (5kg-80kg) Polyprop Bags are cut into various sizes with on opening left open and the other stitched closed. Our Polypropylene Bulkbags which varies from a 400kg capacity to 2000kg capacity is manufactured accordingly to the client's specific needs.

Our Bulkbags have different manufacturing options for the top of the bag and again for the bottom/end of the bag.

What is UN Certified Packaging for Dangerous Goods?

Safe transport of hazardous materials or dangerous items requires packaging that has been evaluated and approved for use by the United Nations (UN). The United Nations Recommendations for the Transport of Dangerous Goods serve as a universal framework for these regulations.

Bulk bags are commonly used for transporting hazardous products including fertilisers, insecticides, and other chemicals that require UN-approved packaging.

For a product to be certified as meeting UN standards, it must be constructed and tested to guarantee that it is strong, durable, leak-proof, and impact-resistant.

What is the UN Standard for FIBC/Bulk Bags?

For a FIBC to earn United Nations approval, it must first pass a battery of stringent performance tests. The goal of these analyses is to verify that the bag is suitable for storing and carrying hazardous materials. In addition, there are strict regulations on how labels and markings can look on UN-rated packaging.

UN bulk bags are made with thicker fabric all around than non-UN bulk bags. Top panel cloth must be sufficiently heavy to withstand the rigorous Topple Test and Righting Test.

Standard FIBCs have a Safety Factor (SF) of 5:1. Bulk bags approved by the UN must have an SF ratio of 6:1. It takes 70 press-and-release top lift cycles at 4x the bag's Safe Working Load (SWL) and one final cycle at 6x SWL for a bag to pass the 6:1 safety factor test.

Once a bag reaches UN certification status, the certification paperwork will provide a "Periodic Design Recertification Date" for the bag, usually one year after the certification date.

The UN Recommendations on the Transport of Dangerous Goods, sometimes known as the "Orange Book," contains detailed requirements pertaining to UN approved packaging. To get the latest version, visit https://unece.org/rev-21-2019. These rules are in place to ensure that hazardous materials don't endanger people or the environment in any way.

Test Protocols for Bulk Bags and FIBCs Adopted by the United Nations

UN bags are subjected to extensive and invasive testing procedures to ensure proper safety when handling dangerous goods because of the often volatile and dangerous nature of their contents.

When loaded to 95%, UN bags need to pass the following tests:• Testing for Vibrations: 60-Minute Procedure • Maintain a 6:1 load for a five-minute period while lifting from the top and/or side. • Twenty-four-hour stacking test with no data loss • Content is unaffected by a fall from any of three distinct heights • Any component of the top can topple without the contents falling out. • FIBC turned on its side is righted by being hoisted into the upright position without causing any tears in the bag. • A knife cut cannot lengthen by more than 25% from its original length.

The UN Recommendations on the transit of Dangerous Goods - Model Regulations should be used for assessing the following characteristics of the fill material in any packaging used for the storage and transit of hazardous materials:• Chemical name and UN number • Class or Group • A United Nations Packing Group

Some bulk bags have higher UN ratings than others. UN rated bulk bags can be found in the same variety of sizes and designs as regular bulk bags. The type of UN bulk bag required depends on the specifications of the product or the needs of the customer. The UN marking on a bag will tell you the basic dimensions of the bag.

Type-specific FIBC identification code:• 13H1: FIBC, No Coating / No Lining • 13H2: Coated, No Liner • 13H3: FIBC, Lined and Uncoated • 13H4: Coated FIBC with liner

How are Woven Polypropylene Bags Made?

The production of woven polypropylene bags is a labor-intensive process that includes extrusion, weaving, printing (if necessary), cutting, and sewing. Their durability makes them perfect for storing grains, cement, and fertilizers.

Material Extrusion:

The process begins with polypropylene resin pellets that are heated and then extruded into thin, flat tapes.

These tapes are the raw material for woven PP bags.


The flat tapes are woven together using specialised circular looms that create the characteristic woven fabric.

The weaving process involves interlacing the tapes both horizontally (weft) and vertically (warp).

The result is a sturdy, flexible fabric with a distinctive crisscross pattern.

Printing (Optional):

If required, the woven fabric can undergo a printing process. This adds logos, branding, or product information to the bags.

Printing can be done before or after the bag is made.

Cutting and Sewing:

The woven fabric is cut into the desired bag size and shape.

The edges are stitched together using specialised sewing machines.

Handles or straps may also be added during this step.
