Advantages and toxicity testing of non-woven planting bags

Non woven planting bags have excellent breathability. Compared to plastic bags, they are more suitable for planting and also beneficial for plant growth. So, how long can non-woven planting bags be used? Does it contain any toxins? How to detect the toxicity of non-woven planting bags? Next, we will delve into these issues in depth.

The advantages and service life of non-woven planting bags

Non woven fabrics have many advantages, such as moisture resistance, breathability, flexibility, lightness, flame retardancy, etc. At the same time, they are inexpensive and recyclable. The service life of non-woven bags can reach about 5 years without being affected by ultraviolet radiation. Non woven planting bags not only have good breathability, but are also more conducive to planting and plant growth. Moreover, their materials are mainly PC and non-woven, which can retain sufficient roots and keep plants stable during transplantation. In addition, non-woven tree bags are made of strong polypropylene material, which has high strength and can effectively prevent plant roots from growing outward and surrounding, ensuring healthy root growth. More importantly, non-woven planting bags have superior environmental performance. After the end of their service life, the bags will naturally rot and will not cause harm to the environment.

 Are non-woven planting bags toxic?

Usually, new non-woven fabrics are non-toxic, and their raw material is 100% polypropylene particles, which are non-toxic and odorless plastics. However, ordinary non-woven fabrics may contain a small amount of formaldehyde, which makes them somewhat toxic.

Several methods for detecting the toxicity of non-woven planting bags

Firstly, there is the sensory testing method: non-toxic non-woven bags are usually milky white, semi transparent, or colorless transparent, with a smooth hand feel; Toxic non-woven bags have a cloudy or pale yellow color and a sticky feel. Next is the water detection method: place the non-woven bag in water and press it down to the bottom. Non toxic bags have a lower specific gravity and can float to the surface; Toxic bags have a high density and will sink. In addition, there are methods such as shaking detection and fire detection to further confirm the toxicity of non-woven planting bags. Through these methods, we can effectively determine whether non-woven planting bags are toxic, ensuring the safety and reliability of our planting process.

Toxic polyvinyl chloride non-woven bags have non flammable properties and will extinguish once they leave a source of fire. Its flame is yellow, the bottom is green, and it can be brushed when softened. Meanwhile, this non-woven bag emits a pungent odor of hydrochloric acid.

Dongguan Liansheng Non woven Technology Co., Ltd. was established in May 2020. It is a large-scale non-woven fabric production enterprise integrating research and development, production, and sales. It can produce various colors of PP spunbond non-woven fabrics with a width of less than 3.2 meters from 9 grams to 300 grams.
