Packaging textiles

Packaging textiles include all textile packing materials for industrial, agricultural, and other goods. Textile packaging is used to contain, carry, store, and protect goods. One of the most important uses of textiles is the manufacturing of bags and sacks, traditionally from cotton, flax, and jute. It consists of synthetic bags used for industrial packaging and jute sacks used for packing food grains. Packaging is a long-established application for textiles. The demand for packing material is directly proportional to economic growth, industrial production, and trade as goods are produced and then distributed both locally and globally. The textile packaging market is growing at a rapid pace, owing to the increasing demand for textile packaging over plastic packaging. The textile packaging is not only resistant to tear but also offers eco-friendly, bio-degradable, and durable solutions. Nowadays, the high consumption of textile packaging can be seen in the medical, retail, food & beverage, and clothing industry. Additionally, stringent regulations passed by the governments to stop the use of plastic and switch to eco-friendly solutions will also help the adoption of textile packaging.

There are some essential uses of technical textiles as packaging and containment such as the manufacturing of sacks and bags, mainly from cotton, flax, and jute. In the modern packaging market especially in the food industry, lighter weight non-wovens and knitted structures for a variety of wrapping and protection applications. On the other hand, tea and coffee bags use wet-laid non-wovens. Besides these, vegetables, meats, and fruits are now more frequently packed with a non-woven insert to absorb liquids, whereas fruits and vegetable products are supplied in knitted net packaging. A number of market trends for the textile packaging sector have been identified, including:

Textile materials can be modified by altering the polymer, fiber, and textile structures. Over the years many techniques have been developed in the polymer and textile industries, with many related technologies developed in chemical engineering, bio-engineering, material processing, and medical sciences. Many unique properties can be obtained by applying chemical, physical, and biological treatments to polymers, fibers, textile materials and composites. This makes it possible to further enhance the performance of textile materials. The raw material from which textiles made is called filaments or fibers. The textile raw materials can be organized into the following groups:

Sustainable packaging is packaging that, over time, reduces its environmental footprint. This can happen in a number of ways: Ingredients: Using raw 100% recycled or raw materials Production process: By minimizing the production process, supply chain, and carbon footprint re-usability: Creating a circular economy around the packaging, extending its life cycle and usability. It is simple to say that eco-packaging is entirely about the environment. It also should take into consideration economic and social factors.

Polypropylene tape yarn carries most woven sacks and FIBCs because it is cheap, strong per gram and easy to recycle as a single polymer. Polyester and polyamide appear where higher temperature or better creep behaviour is needed, and recycled PET is gaining ground in strapping. More in Fibers and Yarns.

Circular or flat woven polypropylene, tubular weaving, leno and warp knitted nets each suit a different load and handling pattern. Weave density, seam construction and lifting loop design together carry the safe working load, and the safety factor is what separates a single trip bag from a reusable one.

A coating or liner keeps moisture, dust and oxygen out and product in. Laminated polypropylene, PE liners and barrier films protect powders and food, and the same layer can carry printing and antistatic or conductive properties for hazardous goods. More in Coated Textiles.

Mono-material construction is the key: keep the fabric, the liner and the sewing thread in the same polymer family so the whole bag can go into one recycling stream. Design for disassembly and clear labelling do the rest. More in Technology and Processes.
