Woven labels are polyester fibers.
Polyester and Recycled polyester are synthetics.
If you think synthetic fiber weaved fabric labels or garments you need to know it is not planet friendly material with many ways.
Polyester is made from petroleum, a non-renewable resource, which in itself makes it an incredibly unsustainable material.
The processing of petrochemicals results in large amount of hazardous waste, and the emissions can be irreversibly damaging to soil, air and water.
Recycled Polyester use more water and chemicals than Virgin Polyester. Recycled Polyester dyers struggling to get a white. Most of dyers using chlorine-based bleaches to whiten the base, irregularity of dye uptake makes it hard to get good batch to batch color consistency and this can lead to high levels of re-dyeing, which requires more water, more energy and more chemical use.
Polyester fibers and Recycled Polyester processing need a lot of KW energy (spinning, weaving, knitting, dye, etc.) and water.
Here are some numbers you can compare the organic and synthetic fibers, FIBER energy use in MJ per KG of fiber:
Hemp, organic 2
Flax (Linen) 10
Hemp, conventional 12
Cotton, organic, India 12
Cotton, organic, USA 14
Ultrasuede 20
Cotton, conventional, USA 55
Recycled Faux Leather 55
Wool 63
Recycle polyester 70
Viscose 100
Polyester 125
Nylon 250

Another critical information about Polyester and Recycled Polyester Fibers.
Do you know microplastic?
When the processing dyes the polyester fibers and when you wash your polyester clothes (virgin or recycled), they shed microplastics (tiny polyester fibers) that are so small that the filtering in our washing machines and wastewater treatment plants can’t catch them.
Those tiny polyester fibers goes in our sewer systems and our oceans, where all sea creatures will eventually eat them.
And so, if you eat sea foods, you’re probably eating plastic too.
Each year 9 billion tons plastic mixing to Oceans!

30 years later total plastic weight amount will be more than total fish weight amount.

​And plastic rains: Each year more than 1,000 tons of micro plastic rain onto Western US. Most of the plastics deposited in both wet and dry samples were microfibers from clothing that microplastics are small enough to be carried in the atmosphere across continents. (Via Utah State University)
Plastic Rain Is the New Acid Rain.

However, if you need to use Polyester Fibers like Woven Labels or synthetic textile materials, use only North American and European manufacturing products.
Because all Asia, 3rd word countries using Natural Gas, Coal kind fossil sources for their electric power. It means our atmosphere has overvalue sulfur, CO2, and a lot of other dirty molecules.
But North America and Europe use mostly Nuclear and renewable energy sources for electric power.

It means, the best way is let us use Organic Fibers fabric labels for your project. Print color technology has changed a lot since 2015.
Today many successful spot, opaque colors printing is possible over organic fibers, including metallic, neon colors.
You can use organic fiber sustainable clothing labels as like Cotton Labels, Bamboo Labels, Linen Labels, Hemp Labels, Soy blended Cotton Labels.​
