 1 Introduction 
Non-woven packaging bag: refers to a packaging bag made of non-woven fabrics, generally used for packaging items or other purposes. The weight of non-woven packaging bags is similar to that of ordinary paper bags and plastic bags, but it is loved by everyone because of its practicability, aesthetics and environmental protection.

 2 quality differentiation thickness uniformity
With a good fabric in a light environment, the difference in the thickness of the fabric will not be great; the poor fabric will appear very uneven, and the texture contrast of the fabric will be greater. This will greatly reduce the weight of the fabric. At the same time, fabrics with poor fabric feel hard and inflexible.
Elasticity

Non-woven fabric is a kind of non-woven fabric. It directly uses polymer chips, short fibers or filaments to wind the fibers through airflow or mechanical web, and then it is hydro-entangled, needle-punched, or hot-rolled, and finally finished. Non-woven cloth formed. Reducing the cost By adding some recycled materials (ie, recycled materials) and corresponding proportions of curing agents to the raw materials, the resulting fabrics have poor resistance to pull and are difficult to recover. Its feel feels thick and hard, but not soft. In this case, bearing weight is poor, and the decomposition will be much more difficult, not environmentally friendly.
Line spacing
The optimal force requirement for the cloth texture is a 5-inch needle, so the bag that is sewn out is beautiful and has strong bearing capacity. Non-woven fabric spacing is less than one inch and less than 5 needles, and the bearing capacity is poor.

Bag bearing
The carrying capacity of the bag is related to the material's resistance to pull, elasticity, and line spacing and line. Imported environmentally friendly materials, the use of 402 pure cotton thread, line spacing in strict accordance with the one-inch 5-pin distance, so as to ensure the carrying capacity of the bag.
Print definition
The basking sun is not firm, the pull is uneven, and the symmetry strength of the walking version master grasps the squeegee; the viscosity of the slurry transferred from the master sizing master; it will lead to the unclear effect of printing
