Chemical Properties Of Polypropylene Material
And PP Woven Bags
While selecting appropriate packaging bags for your produce, this is certain that you will encounter polypropylene woven sacks/bags manufactures and they will ask you to go for the same. This is because, the PP bags are in vogue, and to a big extent capable of overcoming all packaging related hiccups.
Another reason for its easy availability is, India produces a large number of polypropylene bags and sacks of diverse shape, size and properties. We also export these products.
All these factors have made PP woven sacks/bags a popular option among buyers. If you are also considering pp woven bags as a packaging material. It is pertinent that you know all the characteristics of woven bags. In this article, we are sharing information about the same.
Characteristics of Polypropylene Material
To understand the property of polypropylene material, and PP bags, it is important to know the chemical composition of polypropylene material first.
What is polypropylene?
Polypropylene is a rigid and tough material. It is a thermoplastic produced from the monomer of propene. This is a liner hydrocarbon resin. It has application in various industries and is made according to the requirement. This is the cheapest plastic available in this market. The plastic has the lowest density. Based on the chemical composition, there are two major types of polypropylene present in the market.
· Homopolymer polypropylene
· Copolymer polypropylene
The copolymer polypropylene is taken in industrial use because of its high strength, impact resistance, and light weight.
Polypropylene is processed to make pp fabric strips, which is then woven to get pp woven fabric roll. This roll is just like any other fabric roll which is then printed or dyed to give its different appearance. Polypropylene has become one of the favourite packaging material for different uses because of its dyeability feature.
The chemical properties of polypropylene transfer many features of it in woven bags. However, makers of PP bags add additives in polypropylene material during processing to enhance its characteristics and make it more user-friendly. There is an array of additives that are added to the material for improving its strength, appearance, resistance and sundry of products made from the material.
Let’s Have A Look On Some Interesting Properties Of Polypropylene Woven Bags
Density Of PP Bags - There are many commodity plastics, and polypropylene is the lightest polymer of all. The low density of PP bags makes them light in weight, however, their weight is not proportional to their strength. The strength of woven bags is much higher.
Chemical Resistance Of PP Bags - The PP bags because of being from the plastic family have resistance against heat, chemicals, etc. But due to its composition and additives added in the same, its resistance increases to a larger extent.
It has excellent resistance to concentrated and diluted alcohols, acids and bases.
Have good resistance to moisture and chemicals.
Flammability - The melting point of polypropylene material is higher, however, if talk about flammability, than the polypropylene material is highly flammable. The polypropylene woven sacks are also highly flammable. However, the positive aspect of PP woven bags is that it has low thermal conductivity. It means, that the material does not allow heat to pass through it easily. This characteristic makes it a suitable packaging material.
It Retains Its Property - Unlike the other packaging material options available, the polypropylene material retains its property at a higher temperature, in humid condition, and even when submerged in water. Polypropylene is a water repellent plastic.
It Is Moldable - The polypropylene has high elasticity, which makes it a moldable material and gives pp bags manufacturers freedom to make bags based on the client’s requirement.
Because of its various properties, the polypropylene material has become one of the best choices for various industries. The PP woven bags have derived most of their characteristics from the material.
