Discussion On The Factors Affecting The Stability Of Feed Woven Bags

What are the factors affecting the stability of feed woven bags? The staff of the woven bag manufacturer summarized the following points:

1. Use temperature: The use temperature or thermal environment of the feed woven bag has a significant impact on the use stability of the woven bag. For example, the use temperature of hot loaded cement bags and asphalt bags increases, and the use stability of the woven bag decreases significantly. The phenomenon that hot loaded cement bags are damaged or hot loaded asphalt bags are stuck together is an example of thermal oxidative aging of cement bags and asphalt bags.

2. Filler materials: The addition of filler materials such as calcium carbonate and carbon black has a negative impact on the stability of feed woven bags. Everything has its own life span, and the feed woven bag will certainly not make an exception. The feed woven bag will be broken after being used for a period of time, or it will become corrupt and not durable after being used for a long time. In fact, people who have only a slight knowledge of woven bags know how to deal with it. Woven bags are made of degradable materials, which can be accelerated by burying them in soil, or they can be seen as dross.

3. Multiple extrusion: polypropylene resin is extruded into woven bags. During the processing, the existence of high temperature, shear stress and trace oxygen causes the degradation of polypropylene resin. The degradation during processing not only has a negative effect on the physical properties, mechanical properties, appearance and color of woven bags directly, but also has a negative effect on the stability of woven bags during use.

Adding masterbatch to polypropylene resin to produce all kinds of polypropylene woven bags has been a widely used method in the plastic knitting processing industry. Therefore, the carrier polypropylene resin in the masterbatch accounts for a small proportion in the woven bag. The feed woven bag has the advantages of high temperature resistance, moisture-proof, mildew proof, convenient stacking, not easy to slide, slightly breathable, relatively flat surface, less damage, good finish, good feel, novel and beautiful, reduced freight, low price, good economic efficiency, reusable, good environmental protection, etc.

It is suitable for various packaging and transportation environments. Due to the function of composite membrane, it has good moisture-proof performance. Multi band folding is made to improve the suture strength of the upper and lower openings. Heat sealing is used to meet higher requirements for moisture resistance, or PE inner membrane high-pressure or low-pressure bags can be added.
