What is Pp Woven Laminated Bag and Why Do We Use Them?

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.

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

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.
