Woven Polypropylene Bags

Woven Polypropylene Bags – Versatile and Inexpensive

The growing use of plastics and other synthetics has served to revolutionise the way that we do many things and has also made its mark on a number of widely differing industries. For instance, today’s carpets are more likely to be made from nylon or polyester than from wool. Similarly, in the packaging industry, hessian sacks and paper packets have become relatively rare and the centre stage spot has long been occupied by a variety of more modern, synthetic alternatives such as woven or knitted polypropylene pockets and bags.

In this case, the synthetic material that has so successively replaced its various natural predecessors is a tough thermoplastic polymer that is resistant to a wide range of acids and solvents. The material is also very versatile and is certainly not limited to use in the various types of packaging in which it is now commonly found. It has, for instance, proved to be a very effective means by which to reinforce concrete.  Today it has become important to the manufacture of a wide range of products including carpets, ropes, various medical items, furniture and even clothing such as the thermal underwear needed in less temperate climates. The demand for this material is huge and estimates suggest that a minimum of 50 million tonnes of it is now produced every year.

Perhaps the biggest and most noticeable change to be experienced by the consumer, however, has been to the manner in which food is now packaged, particularly in the case of the more perishable varieties. While much of the application of this and various other new materials has been devoted to improving the presentation of goods for marketing purposes, there have also been some significant practical improvements. A typical example would be the containers now used in the fast food industry that are microwaveable for reheating purposes. In addition, both the transportation and in, many cases, the presentation of fresh produce has now been made easier and safer with the use of woven polypropylene in the form of pockets and bags.

In South Africa, Landpak and Brits Bag Manufacturers (BBM), both members of The International Group of Companies, are major local producers of these items. The Group’s marketing arm operates under the name of International Bag Buyers (IBB) and supplies farmers, wholesalers and retailers with these and other products made from the same or related materials. In total, IBB handles around 6000 different products for commercial, industrial and, of course, agricultural packaging purposes.

Produced in a variety of sizes and colours, they are exceptionally strong yet sufficiently elastic to accommodate fruit or vegetables without the risk that undue pressure might lead to spoilage.  The choice of colours that includes white, red, green, yellow, orange, purple and blue act as an ideal means of immediately identifying their contents based on logical colour coding. For instance, while green could be used to identify avocados, purple would be more appropriate in the case of aubergines.

In its untreated state, the raw material is fairly susceptible to degradation by sunlight. For this reason, the better quality products, such as those offered through The International Group of Companies, are specially treated during the manufacturing process with additives to make them UV-resistant. Typically this will retard the degradation process for at least three months; more than enough time for perishables. Thereafter, these items will continue to degrade naturally.

While there remains a role for natural materials in the packaging and other industries, concerns over the depletion of natural resources is certain to drive the further development of synthetics. While many of these still pose a threat to the environment, the move to more biodegradable materials is helping to restore some balance.

When choosing from the extensive range of woven polypropylene pockets and bags manufactured and supplied by The International Group of Companies, the packaged products, the consumer and the environment will all benefit.
