Bulk storage of items, like food grains, requires either bulk bins, structures, or bulk packaging bags. Packaging bags are preferred for bulk storage. Manufacturers produce these bags using different materials. For example, jute bags, paper bags, polythene bags, high-density polyethylene (HDPE) bags, and polypropylene (PP) bags. Polypropylene sack is the most sought after bulk packaging bag. PP is a kind of plastic that possesses all the desirable qualities for bulk storage.
Types of polypropylene-based bags
Bulk storage bags made using thin strips of polypropylene. Depending on the process of manufacture, the bags may be woven or non-woven. Woven sacks are made of PP woven fabric. It is a textile formed by weaving on a loom, made of many threads or strips woven on a warp and a weft. A layer of BOPP (Biaxially Biaxially oriented polypropylene) can laminate the fabric for providing more strength and durability. Polypropylene woven bags are the toughest packaging bags. Non-woven bags result from fusing strips of polypropylene together.
Uses of polypropylene-based bags
These bags being strong are widely used to pack materials for the grain, milling, and sugar industry. Woven bags manufacturers produce packaging bags for pulses, dry fruits, wheat, rice, and other food products in a hygienic facility using the best raw materials. International standards are followed while designing and printing bags by most of the manufacturing units.
Additionally, polypropylene-based bags also package the products from different industries, like:
· Tensile strength: This allows packaging bags, like polypropylene rice bags, to hold large amounts of load.
· Reusability and recyclability: This property safeguards the environment from damage.
· Cost-effectiveness: These plastic bags are cheaper than other kinds of plastic bags.
· Resistance to water and humidity: This quality ensures that the integrity of the bag is intact with a change in humidity. Resistance to water prevents the internal contents of the packaging bags from damage.
· Resistance high temperature: Packaging bags made from polypropylene can stay intact even at quite high temperatures. This property even allows the production of reheatable and resealable retail packaging bags.
· Chemical resistance: This property safeguards the internal contents of the bags from damage in case of chemical spillage.
· Microbial resistance: Bags for the packaging of food grains, fruits, and flour should be able to provide protection against microbial action. The nature of polypropylene to safeguard against rot, mildew, and bacteria is favorable.
· Resistance from rodents: Polypropylene is difficult for rodents to chew. This prevents the internal contents of a packaging bag from rodent attack.
· Impact resistance: A polypropylene sack is tear-resistant. Rough handling of such a sack does not damage the internal contents.
· Colorful and Attractive: Bags based of polypropylene are available in different colors. They can also be customized for attractive packaging. For instance, a transparent window helps the customer to view internal contents without opening the bag. In addition, metalize film or printing of brand images can further increase the appeal of the packaging bag.
· Lightweight: Low weight bags require less space and are easy to carry.
· All-time availability: Unlike their jute counterpart, polypropylene-based bags can be available for use throughout the year.
· Gusset: Polypropylene has anti-static property; therefore, bags made from it can stack comfortably.However, the addition of a gusset in these bags improves its ability to stand.
India is the number one exporter of top quality PP bags, such as leno bags, in the world. Developing countries have an edge over developed countries in the case of the packaging industry. This is because it is a labor-intensive industry and requires a lot of employment. Hence, PP woven bags suppliers and manufacturers along with customers and clients of pp bags contribute to the development of the nation.
