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.
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 weve outlined the difference between woven and non-woven pp bags for you in this blog.
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.

Lets break this question into three sections.
Woven, or weaving is a method by many threads or tapes woven in two directions (warp and weft), to form a fabric for plastic industry needs.
In the plastic woven industry, with a plastic film is drawn into filaments, woven into fabric/sheet/cloth. It can be into a tarpaulin, woven bags, container bags, tons of bags, geotextile fabric, color of the cloth and so on.
Woven or weaving by industry:
Plastic film into a fiber, it should belong to the plastic industry;
Filament weaving process from the plastic into view, it should belong to the textile industry.
Thus, it is both plastic and textile industries marriage of the body.
Woven fabric cloth usually frays at the edges, unless techniques are used to counter it, such as the use of pinking shears or hemming.
Polypropylene, which is also known as PP for short name, is one kind of thermoplastic resin material that produced by the polymerization of propylene.
Woven polypropylene is polypropylene strips/threads that have been woven in two directions (warp and weft) to creat a light, but strong and heavy duty material.
Build with circular woven polypropylene fabric, one side sewn as the bottom, leave the other side open, the simplest woven polypropylene bags is done.
High Melt Index with low Density
Bags or sacks is appropriate to describe something in a wide range of packaging types.
A bag is, a flexible container with a single opening.
A sack is, a bag made of paper or plastic for holding.
Sack is just one type of Bag, especially applying to the packaging industry. In fact, most countries use BAG more frequently than sack. There will be differences but little, so as far as we know, woven polypropylene bags = woven polypropylene sacks.
The fact is different names used in different countries and regions. More bag details needed if we came to a conslusion that its the woven polypropylene bag.
The properties of woven polypropylene bags come from two aspects:
1. Properties of polypropylene
2. Properties of woven method
Polypropylene has qualities of rot/flame/chemical resistance, and woven method means strong yet breath. Combining together with other factors, we got 9 facts of woven polypropylene bags.
· Woven Polypropylene Bags are reusable.
· Woven Polypropylene Bags dont degrade when wet.
· Woven Polypropylene Bags are naturally resistant to tearing.
· Woven Polypropylene Bags can be printed on one side or both sides.
· Woven Polypropylene Bags allow the contents to breath until air dried.
· Woven Polypropylene Bags have better burst strength than plastic bags.
· Woven Polypropylene Bags can be laminated as the vapor and moisture barrier.
· Woven Polypropylene Bags can be partially transparent for outstanding presentation.
· Woven Polypropylene Bags can be side gusseted to accommodate bulky items easily.
PP woven bags are largely used in storing and transporting agricultural products such as aquatic products, feeds, fruits, vegetables, etc. PP woven bags used in the agricultural industry typically include feed PP woven bags, chemical PP woven bags, fertilizer PP woven bags, vegetable woven bags and fruit mesh bags.
PP woven bags are increasingly used to pack food. Common food woven bags include rice PP woven bags, flour PP woven bags, maize woven bags, etc.
Big Packing supply professional and honest service.
PP woven fabrics are extensively used in the construction of irrigation works, roads, railways, ports, mines, buildings, and more. Having the functions of filtering, draining, isolation and anti-seepage, PP woven fabrics are one of the most popular geosynthetics.
Temporary tents, sunshades, and various travel bags can be made by PP woven fabrics. In addition, plastic woven fabrics can also be used as fences and screens during construction.
PP woven bags are almost used by everyone, whether workers, farmers, or cargo agents etc. You can find plastic woven products (such as shopping bags, logistics bags etc.) in stores, warehouses and houses, nearly everywhere.
Woven bags play an important role in reducing or preventing the detrimental effects of flood waters. They are widely used in the construction of dams, river banks, roads and railways. Woven polypropylene sandbags are widely used all over the world.
Special woven bags are used to serve some special purposes. For example, UV resistant woven bags have UV protection and anti-aging function, allowing them a longer lifespan in the sunlight. Woven polypropylene tube with UV protection can be used for earthbag buildings.
Yes, its an eco-friendly fabric. It can be melted down, recycled and made into other products. Besides, they last long enough and can be used many times to reduce your demand from single-use products.
Woven polypropylene bag can last between four and five years if proper use.

Bopp laminated woven polypropylene bags is best suited to graphic and digitally created art work. Perfect for 100% print coverage with no limit to creativity!
Polypropylene A type of polymer used in producing monofilament and multifilament yarns and threads. It is recyclable and is used as our standard fabric.
Yarn / Tape Extruded PP sheet, slit and stretched in annealing ovens to form part of the woven fabric for the bag.
Warp Yarn or tape in a fabric, oriented perpendicular to the Weft yarn during weaving. This would go from top to bottom in the body fabric.
Weft Yarn or tape in a fabric, orientated perpendicular to the Warp yarn during weaving. This would go from left to right in the body fabric.
Woven Combined with many polypropylene yarns or tapes in two directions (warp and weft) to form fabric.
Denier The weight of yarn in grams per 9,000 meters.
Fabric Mesh The measure of the density of the fabric weave, measured as the number of yarns per inch in both the Warp and Weft directions. Like 10×10 mesh.
Fabric Weight The measure of the fabric weight in ounces per square yard or grams per 100 square centimeters.
Stitches per Inch A sewing specification requiring X number of stitches per inch. Like 4 stitches per inch.
Seam A sew line made by the attachment / assembly of two or more components.
Top Hemmed / Hemming A fold and sew operation which prevents fraying of cut fabric. This also provides a clean finish to the woven polypropylene bag. It may be either towards the inside or outside of the bag.
Body Fabric The tubular portion of a seamless or circular woven bag.
Breathable Fabric / Bags Uncoated or non-laminated fabric / bags.
Circular Woven Bag Also called a tubular bag, it is made from fabric woven on a circular loom, which is then cut to the proper length for a specified bag height, thereby eliminating the seams on each of the bags sides.
Coated Fabric / Bags Fabric or bag which is coated / laminated with Polypropylene (PP) to prevent moisture intrusion or sifting of the contents. Also called Non-breathable or Laminated fabric / bags.
