New polypropylene (pp) woven bags have become a popular and versatile packaging material for very many industries since they are strong, durable and cheap. This article encompasses all the necessary information a reader may require to understand the PP woven bags including the composition of the bags, the process of manufacturing the bags, and some benefits as well as the uses of the PP woven bags across different industries.
As the name may imply, PP woven bags are bags manufactured through the weaving of polypropylene plastic material which provides a strong fabric. Polypropylene could be described as a thermoplastic polymer which is synthesized by the polymerization of propylene gas by way of a catalyst system. It is recognized to be very versatile, cheap, and has immense durability and is also well protected when coming into contact with chemicals.
This fabric is very strong and flexible and is highly resistant to chemicals such as acids, alkalis and solvent. It consists of two PP plastic tapes woven in a figure of eight manner with the tapes passing over and under each other at regular intervals. These bags are rugged and sturdy for rough usage owing to the fact that the layers are welded together and have strong seals on the sides. PP woven bags can also come in different sizes and shapes, including rounds, squares, or blacks and can be made in different thickness and colored.
Advantages of PP Woven Bags
There are several beneficial properties of PP woven bags that make them a packaging material of choice across various industries:
- Durability: These bags are manufactured from high-denier polypropylene and are rather durable, especially in terms of mechanism abrasion. It provides a strong and dense needling that does not get torn or ruptured even when it is laden with weight.
- Water Resistance: The chemical constitution of pp woven bags makes them water proof, hence their name hydrophobic. The material used in the bags does not allow passage of liquids or moisture in it making them ideal for use in transporting moist produce or products.
- Chemical Tolerance: These bags have a high ability to cope with most acidic and alkaline solutions as well as solvents and oils, which enhances their capability to contain corrosive substances without undergoing any chemical reaction. It is important to widen the application of this property across the chemical and pharmacy sectors.
- Reusability: PP woven bags are reusable and can be used more than twenty times, so if well maintained they can be used for many times. The materials used in the fabrication of these bags enable multiple usage for storages and transportation before recycling.
- Cost-Effectiveness: PP bags offer a cheaper approach than jute or burlap bags. This also helps to reduce the costs of freighting them due to their light nature when in structure.
- Customizability: These bags can be produced to fit particular sizes and thicknesses, and can also incorporate specific types of closure and handles and may be printed with logos or text for marketing.
- Sustainability: The type of PP woven bags can be recycled once they have been used and are ready to be disposed of. WoPPen bags are environmentally friendly since using them will eliminate landfill dumping and minimize resources used in manufacturing new bags.
Uses of Woven Polypropylene Bags
Owing to their versatile properties, polypropylene woven bags have a far-reaching range of applications across sectors:
- Agriculture: PP woven bags offer very good bulk packaging and are used for carrying fruits and vegetables, grains and animal feed, fertilizers, and pesticides. Another advantage of their waterproof nature is that they help maintain the quality of agricultural produce in terms of freshness when they are stored in them or when they are being transported. These bags are normally recycled for their presumed functionality as sand bags particularly in agricultural practices.
- Textiles and Apparel: Woven polypropylene bags are widely applied by garment manufacturers as packaging materials in packing and transporting finished garments and fabric rolls. They are light structures that minimize the expenses that are incurred on freights. Some bags also come with a clear plastic film or a see through window for convenience when identifying what is inside the bag.
- Building and Construction: PP cement bags, concrete bags and FIBCs aid in easy packing and movement of sand, aggregates and other construction materials which are in a loose form. These bags are also collected and then used in construction sites for disposal of debris or even as barriers.
- Chemical Industry: Since they are made to withstand corrosive substances, they are used to hold and transport large quantities of acids, solvents, alkalis, fertilizers, and other related chemicals in a safe manner to avoid spillage and mixing with other contents. Their fabric is waterproof and, in case of a tear, they still do not allow water to pass through.
- Food Processing: Since PP bags are approved by FDA to come into direct contact with food, they are very useful in storing and transporting cereals and grains such as flour and sugar, dairy products, coffee beans and other perishable foodstuffs. Their water proofing characteristic does not allow moisture and thus retain the quality of the article.
- Healthcare: Woven polypropylene bags provide convenient packaging and conveying of medical devices, drugs, surgery apparatus, sanitary & hygienic products. They act as containers that help eliminate the risk of contamination and the presence of bacteria. It also has the feature of maintaining certain conditions and it can also be customized in bags.
- Retail: Most of the retailers utilize printed PP bags for packing of articles of small consumer goods like nails, threads, fabrics, jewellery articles, toys, pencils, garments etc. The transparent pp bags ensure easy visibility of the product thus making the product easily displayed. PP bags are cost effective and better to plastic carry bags in reducing the impacts on environment.
Due to the different characteristics of polypropylene woven bags, they are ideal in various uses where cost efficiency, reliability and safety are considered paramount. When manufactured and/or recycled properly, they help to reduce the amount of negative contribution to the environment by packaging waste. It also increases business profitability because they are affordable and can be made to fit the company’s specification. Demand for better packaging across the globe has also increased, especially for applications requiring durable and sustainable packaging solutions and PP woven bags have emerged as the preferred workhorse packaging material for the present and the future.
