It&#;s easy to tell if a laminated bag you have is made from woven or non-woven PP.  Just look inside. If it has the checker-board look of weaving, like threads going at ninety degree angles, it is woven.  If it has a steady textured look, it is non-woven.

Plastics are not all created equal. Plastics are as different from one another as wool and cotton.  Sure wool and cotton are both natural fibers, but one comes from animals and other from a plant, and we all know how they feel when we use them.

Used to make everything from lunch boxes, and pens to bottle caps and car parts, polypropylene is among the most versatile of plastics.  It can It turns out, there are two ways to take polypropylene plastic and make it into a fabric.

Woven PP is made by pressing long strings of polypropylene molecules (called polymers) together to make a threat-like strip, then weaving these fabrics as you would any other fabric.  Woven PP has been used to make sacks for a number of industrial uses like sand bags as well as for packaging bulk coffee, rice and other dry foods.  It is clean, strong and easy to sew, a natural for bags.  Woven PP is usually laminated to the strands together as they are slippery and can separate easily.  Because the PP can dry out at a different rate than the lamination, laminated PP tends to pucker a bit after a few months.

Non-woven PP is made by taking polypropylene polymers and spinning them using heat and air into long fluffy threads, like cotton candy, then pressing the threads together between hot rollers to get a flexible but solid fabric with a weave-like texture similar to canvas.  The texture leaves the fabric breathable, with a look and feel that is generally pleasant.  The color and texture of NWPP can last for years.  Screen printing in a few colors is an easy process for graphics.

Woven PP is usually white and achieves graphics with the lamination, though some woven PP fabrics use colored threads to make a plaid sort of pattern and clear lamination.  Our NWPP wholesale shopping bags can be made in a solid color imaginable.

4 Uses For Polypropylene Fabric Bags

The numerous advances in synthetic polymers have given us a variety of innovative materials, including polypropylene. When Giulio Natta invented polypropylene fabric in , he had no idea of the extent to which his creation would change the packaging industry.

You may have heard the term woven polypropylene regarding the commonly used FIBC bulk bags but what does it mean? 

Polypropylene (PP) is a type of thermoplastic resin that is now widely used across different industries. The synthetic resin material is completely resistant to acids, bases, and chemicals, which makes it the best material for many industrial applications. 

Woven PP is created by taking threads of the material and then interlacing them together to create a lightweight yet surprisingly sturdy fabric. This is how the FIBC bags or bulk bags are made. Woven PP bags are also called rice bags, salt bags, sandbags, coal bags, seed bags, feed bags, firewood bags, fertilizer bags, cement bags, and chemical bags depending on the region and industry.

Various Uses of Polypropylene Fabric Bags in Packaging 

In addition to being lightweight and waterproof, woven PP is also non-toxic and low cost. This makes it an adaptable and effective option for different applications:

Agricultural and Food Products 

FIBC bulk bags are largely used in holding and moving agricultural items like feeds, grains, vegetables, fruits, aquatic products, fertilizers, and more. As mentioned earlier, these bags are non-toxic so there is no risk of contaminating the food items. Also, they are anti-seepage, so items like salt, sugar, and flour can&#;t pass through the bags during transportation.

Daily Life Goods

The polypropylene fabric is often used to make travel bags, sunshades, and temporary tents. From farmers and construction workers to cargo agents, today almost everyone uses PP woven bags in one form or another. If you own a pet, the pet food you buy also usually comes in a PP bag or FIBC bag.

Geotechnical engineering 

PP woven bags are also used in the construction of roads, mines, ports, irrigation networks, buildings, railways, and pretty much everything else. These bags can perform the necessary functions required during the construction projects like filtering, isolating, draining, and more; this is why PP fabric is the preferred geosynthetic in many civil engineering projects.

Flood control 

Woven PP bags &#; in the form of Sandbags &#; play a critical role in preventing or reducing the detrimental effects of flood waters too. Since the polypropylene fabric is resistant to water, dust, and tearing, and don&#;t get affected by rodents or soil bacteria, they make excellent sandbags.

Sandbags were primarily designed for military applications and temporary flood defense but now they are used in construction industries across the world.
