High-Quality Polypropylene Bags for Sale – Trunel Bags South Africa

Trunel Bags is South Africa’s trusted supplier of polypropylene (Polyprop) bags, offering durable, affordable, and eco-friendly packaging solutions since 2008. Whether you're looking for bulk packaging for agriculture, mining, food processing, or general storage, we supply woven and plastic bags in a range of sizes—from 5kg to 2,000kg. Based in Gauteng, we offer fast nationwide delivery and expert advice tailored to your packaging needs.

What Are Polypropylene Bags?

Polypropylene bags are made from woven thermoplastic polymer threads, measured in GSM (grams per square meter). The higher the GSM, the thicker and stronger the bag. These bags are known for their exceptional durability, moisture resistance, and ability to withstand heavy loads, making them ideal for transporting and storing a wide range of products.

All Trunel polypropylene bags undergo stringent testing in state-of-the-art labs to ensure top performance. They can also be UV-treated for longer outdoor durability and laminated to prevent leakage of fine products through the weave.

Printing Options for Polypropylene Bags

We offer two printing methods to customise your Polyprop bags:

• Standard Ink Printing: An economical option where your logo is printed directly onto the raw woven material.
• BOPP Printing: Delivers high-resolution, photo-quality prints by attaching a printed plastic layer to the bag using heat sealing. This method is ideal for premium branding but comes at a higher cost.

If you’re just starting a business, we recommend the cost-effective standard print. As your brand grows, you can switch to BOPP printing to elevate your packaging's visual appeal and boost shelf impact.

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.

Weaving:

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.
