100% PET (polyester) spunbonded nonwoven fabric as the substrate material of coating or lamination because its special reason below:
1. Good tensile strength, excellent uniformity, anti-pull and tear, anti UV-and aging, anti-gamma, corrosion-resistant, soundproof, moth-proof and etc.
2. High temperature resistant:
The melting point of PET spunbond fabric is around 260℃ which is
dimensional stability in the high temperature conditions. It is widely
and largely to be used for various nonwoven bags printing.
We also call it heat transfer printing. It is beautiful, fashionable
as you want. This increase the image of the products by people's
As this feature, it is also used as
the substrate of composite materials for high temperature lamination.
Ultrasonic composite is also perfect.
3. Hydrophobic: It is the feature of nonwoven which means the spunbond nonwoven fabric itself does not absorb any liquid. We also call it water-repellent or water resistant (waterproof).
4. Lightweight and durable: Compare to spunbond PP nonwoven fabric it is lightweight and durable. For example, Same weight 50gsm, pet spunbond nonwovens has better strength than PP nonwoven. Technical data of 50gsm pp spunbond nonwovens equals to around 35gsm polyester spunbonded nonwoven fabrics. In some way, you choose polyester spunbond it is also saved the transportation costs because lightweight. (In one container, you can load more products)
5. Air permeability:
Means air can go through the nonwovens. So, desiccant packaging
nonwoven can absorb the moisture air to dry the environment conditions.
