The Three Grades Of Polypropylene Bags And Its Characteristics

Polypropylene is one of the most used polymers at present. It is used both as plastic as well as fabric because of its versatility. When the polypropylene is thinned and cut into strips, it is woven to make pp woven fabric roll. The fabric roll is finally used for making pp woven bags. 

It is important to note that polypropylene fabric comes in different grades. The price of fabric or bag depends on the grade of fabric. Therefore, when you are in the market to pick polypropylene bags, do check the quality of fabric. Here are a few details that will give you insight into what quality of the woven bag you are buying and its application suitability. 

Polypropylene is divided into three grades, and each grade of PP fabric has its unique property. You can choose the fabric based on its application. 

Homopolymer Polypropylene - This is the primary grade PP resin. This grade is more rigid and has high-level resistance to temperature. Therefore, this grade of polypropylene woven bags is used for making bags suitable for the high-heat application. Additionally, it also has a high melting point, excellent chemical resistance and scratch resistance. This grade of polypropylene bags is not recommended for freezer application as its impact resistance get lowered at low temperature. 

Random Copolymer Polypropylene - This grade of polypropylene has additional ethylene. The presence of ethylene gives these grades of pp woven sacks/bags a lower level of rigidity in comparison to their counterparts. However, it has a better impact strength, softer feel, heat sealability, resistance to environmental stress, better clarity and lower melting point.

Impact Copolymer Polypropylene - This grade of polypropylene has a higher content of ethylene than random copolymer polypropylene, therefore, it is much tougher than the other two. It is suitable for all types of application from freezer to microwave. The presence of ethylene increases its impact resistance at low temperature as well. 

These are three grades of polypropylene fabric that has different applications. When you need woven polypropylene sacks/bags, check all three grades and buy one that best fits your application requirement.
