In order to make this thermoplastic polymer resin, propylene (a colourless gas) is extracted from crude oil using a chemical reaction and then polymerized to form a synthetic substance with very large molecules known as a polymer. These molecules are then heated, extruded in a flat sheet and cooled so it can be split into thin strips that resemble threads.
Before being woven together to create the finished fabric, the threads are heated, stretched and cooled multiple times to achieve the required strength.
This woven PP can then be used to make a wide range of products such as commercial packaging sacks and reusable shopping bags.

Just like any other plastic, it should be kept away from heat which means no ironing.
The weight per unit area of woven fabric is expressed by gram weight per square meter (gsm), which is an important technical index of woven fabric. Gram weight per square meter mainly depends on the density of warp and weft and the thickness of flat yarn so the higher the gsm the denser the fabric.
All weights include lamination which typically adds approximately 20gsm to woven PP fabric.
Typically tends to be muslin fabric which is very light weight and hence has also got very little strength.
Light weight cotton which is typically used as lining or for cheaper price focussed products.
The most popular weight of cotton used as it provides the flexibility as well as as the strength needed to make many products. This weight of cotton is widely produced making it the most cost-effective option.
This is heavier cotton where the product needs to look more premium than a regular one.
Woven PP can be dyed to hundreds of colours although Pantone matching is not available.
The final step in the production of woven PP fabric is applying any finishes that will enhance the material by adding special characteristics or changing the look or feel of the material.
There are various finishes that we often add to woven PP depending on the product that it is being used to make. Here are a couple of the most common:
Available in gloss or matt and can be applied to canvas to make it even stronger, sturdier and more durable. This is a great finish when creating a bag or product that is required to hold its shape. The three types of lamination we use are PP, which uses less plastic, LDPE, which is more recyclable, and HDPE.
When another material is stuck to the canvas using a glue such as an inner lining for a bag or jacket.
The fibres are treated with starch to help stiffen the fabric allowing it to hold its shape.
A wax coating is applied to the surface of the fabric to make products that are more suited for outdoors such as bags and jackets.
Woven PP can easily be branded with your artwork using a variety of techniques. Learn more about each one here
• Screen Printing
• Transfer Printing
Twill is most notably characterized and regarded by its diagonal weave. This pattern is created by weaving the weft thread over one and under two (or even more) warp threads to give an appearance of diagonal lines. It creates a very lightweight fabric and makes for a great printing surface.
Needle Point Canvas
An open-weave fabric with small holes in between the yarns. It is mainly used in needlepoint embroidery.
We can provide canvas with various certifications such as:
