Used across many different industries, woven polypropylene bags are common. Whether you’re manufacturing woven polypropylene sandbags or need sturdy shopping bags, you’ve seen woven polypropylene bags in your day to day life. What makes polypropylene the top to bottom choice over other synthetic materials? This, and more reveals itself through our comprehensive guide on woven polypropylene bags.
Polypropylene, a synthetic polymer, found its beginnings back in the 1950’s. It is a type of plastic who’s uses extend into anything. Some products made with polypropylene include:
And much more. Polypropylene is in such high demand because it is the most versatile polymer in the world. It is also lightweight and has very little density.
Polypropylene is distilled with other chemicals and combined with catalytic chemicals to transform into a polymer. Once in a polymer state, fabrics create many products.
You probably know woven polypropylene bags best as reusable bags you find at a grocery store. They’re made with the thermoplastic resin known as polypropylene. This heavy duty resin forms into filament for weaving. The weaving pattern for polypropylene bags is typically a plain weave.
The weaving process assists in the bag’s strength. The plain weave, which is the most common weave to use, places a number of threads together. Warp and then weft weaves create this fabric. The threads or yarn that are longitudinal are the warp. These threads or yarn are held, while the weft yarns or thread weave over and under the warp. This weave pattern produces an even distribution over a fabric.
The polypropylene filament goes through a lamination process to mend the filaments together. They won’t shred once established. When the polypropylene bags go through their weaving stage, they’re lamination process acts as a sealant. Store goods like coffee beans, rice, and other dry goods with polypro bags.
Both woven and non woven polypropylene bags are made from polypropylene filament. This polypropylene filament is traditionally made from recycled plastic when it’s converted to the polypropylene. Both styles of bags also offer uv protection. If you’re taking your non woven or woven polypropylene bag out with you, you don’t have to worry about uv rays affecting its overall structure.
The biggest difference between woven and non woven polypropylene bags are within their manufacturing. Woven polypropylene bags use a plain weave, while non woven polypropylene bags come bonded together. Meaning, if your polypropylene is non woven, it went through a special adhering process to keep all of the filament together.
Each version of polypropylene is durable and strong for extended use. After all, what matters is the material, and polypropylene is great for holding many different things.
Both woven and non woven polypropylene bags are great for dyeing. They come in a variety of colors to suit your style. They’re also great for placing artwork upon its surface. If you’re looking to add a graphic to your polypropylene bag, both non woven and woven polypropylene bags are up to the challenge. If your design is more intricate, the non woven polypropylene would work better.
Woven and non woven polypropylene have excellent benefits for use. Some great uses for both woven and non woven polypropylene are:
