Physical indicators of non-woven fabric surface: Investigate whether the fabric surface is shiny. Is there any fiber floating on the surface, if it is dull or there are too many floating silk, it is probably produced by recycled materials. Tear a piece of cloth, burn the whole with fire, and investigate the incineration residue, good product, the residue is small and flat, produced from inferior material, and the residue has many tiny particles of dust. If time permits, you can take one square meter and expose it to the sun. Poor quality non-woven fabrics cannot withstand sunlight and ultraviolet rays. After 7 days, there will be obvious changes. If you tear it by hand, it will be easy to tear.
Appearance indicators of non-woven fabrics: randomly select a sample of 2 meters for testing, open it in a place with light, and visually inspect the surface of the cloth for unqualified defects such as broken wires and hard blocks.
At the same time, pay attention to whether the light transmission function of the cloth surface is common (this is an important and simple way to judge the uniformity of the cloth surface). Then lay it on a flat ground, the product with good uniformity, and the cloth surface should not be bumpy. Prices vary by texture, size and thickness.

In terms of functionality, non-woven bags are not only suitable for single-item restaurants, but also for restaurants with complex food categories. Because the surface is relatively rigid, packaging boxes of different standards can be combined and placed inside. The other square shape also makes the sense of planning quite superior, the performance space is large, and the special planning can be seen at a glance even from a distance. Other non-woven bags are strong in texture and are often recycled by customers, which not only helps environmental protection, but also can do secondary publicity for enterprises. But because of the high price, there may be more choices of non-woven bags with high customer unit price.
