Specialized analysis of polypropylene, the raw material of mesh bags
In the field of agricultural packaging, the mesh bags produced by our factory have become the preferred choice for the transportation and packaging of many vegetables, fruits and other agricultural products due to their outstanding performance. As a plant manager with 20 years of experience in the industry, we’d like to share our knowledge of the key raw material behind mesh bags. The raw material we use to produce mesh bags is polypropylene. Polypropylene, or PP for short, is a thermoplastic synthetic resin with excellent properties. It plays an irreplaceable role in the manufacture of mesh bags.
In terms of origin, polypropylene is produced from propylene monomer through a polymerization reaction. This raw material offers a number of unique advantages that make it ideal for mesh bag production. First and foremost, polypropylene has excellent air permeability. This feature is extremely critical for packaging agricultural products, we loaded in mesh bags onions, potatoes, apples, coconuts and other fruits and vegetables in the transportation process need to breathe, good ventilation to ensure that the bag air circulation, can greatly slow down the deterioration of fruits and vegetables, so that consumers get their hands on the fresher produce.
Secondly, mesh bags made of polypropylene are flexible, strong and not easily deformed. In daily production, we have repeatedly tested, the same specifications, polypropylene mesh bags can withstand greater weight without rupture. For example, mesh bags filled with coconuts, even if a certain degree of extrusion and collision in the handling process, but also by virtue of its good elasticity and strength, to effectively protect the permeability of coconuts, and in the process of transportation does not break, while the mesh bag itself will not be easily deformed, and can be reused many times.
Furthermore, the polypropylene material is light, soft, smooth, made of flat silk body in the packaging of fruits and vegetables, can gently fit the surface of fruits and vegetables, in the transportation of bumps in the cushion provided for its fruits and vegetables to avoid fruits and vegetables and friction with the packaging caused by scratches, such as delicate pineapple, carrots, etc., can be in transit to get attentive care.
From drawing to weaving, cutting to sewing, polypropylene shows stable physical and chemical properties throughout the entire production process, always guaranteeing the high quality output of mesh bags for the safe transportation of your agricultural products.
