Woven vs. Non-Woven polypropylene bags: what is the difference?

Reusable bags are more popular now than ever before, with an amazing selection of bags available made from eco fabrics including paper, natural fibres such as cotton, and even polypropylene.

You can find more information on our web, so please take a look.

Polypropylene (also known as PP) is a hugely versatile type of plastic, used for making a variety of items from lunch boxes to bags! Here at Cotton Bag Co, we have two options available for polypropylene bags (PP), non-woven PP and woven PP, and whilst these bags are fairly similar we&#;ve outlined the difference between woven and non-woven pp bags for you in this blog.

 

So, what is the difference between woven PP and non-woven PP bags?

Non-woven and woven polypropylene are made from the same type of plastic resin, but they do differ in the way that they are formed.

Woven polypropylene consists of polypropylene plastic threads that are woven together, creating a durable material with a great deal of flexibility and strength. In contrast, non-woven polypropylene bags are bonded together instead of woven by fusing the fibres using heat and pressure.

While both woven and non-woven PP bags offer excellent durability, woven PP bags create a heavier duty material that can withstand more pressure and weight which is why these bags are often used for parcel collections or for bags that need to be able to hold a lot of weight without risk of giving in.

Both types of PP bags are 100% recyclable, being just one step away from the bio-based plastics at the best end of the Greenpeace pyramid of plastics. Plus, there is the added benefit of this material being waterproof when finished with a laminated film, helping to protect contents from moisture.

Our printed non-woven PP and woven PP bags are available in a range of vibrant colours and can be dyed to suit your design and your brand. Your design can be printed over the whole of the polypropylene bag surface as we reverse print on to a matt or gloss lamination.

Woven vs. Non-Woven PP

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.
