In 1954, Professor Natta created a thermoplastic, polypropylene (PP), in Spain. It was a versatile polymer with usage as both a plastic and fiber. Good resistance to water, chemicals, fatigue, and heat; endurance, and optimal rigidity made PP an all-time favorite in the food packaging industry. Moreover, the US Food and Drug Administration marked PP-based containers and bags safe for food packaging. Frequently, retail markets and warehouses store polypropylene woven sacks of food grains like rice, wheat; flour-like besan, maida; animal feed, and fruits.
What Properties Of Polypropylene Are Helpful For Food Packaging?
- As a flexible film, PP takes shape of the food material, thereby prevents wastage of space. The semi-rigid nature of the polymer helps manufacture varied containers for the packaging of food. Stitching PP woven fabric roll into pouches, sprouts, jumbo bags, and retail bags are possible.
- Packaging food in PP prevents wastage of food. For example, bags made with leno weaving maintain adequate breathability. This prevents spoilage of fresh agricultural produce like onions.
- PP is a polyolefin that does not react with food, thus, it is safe to pack food items in polypropylene woven bags.
- PP has high impact resistance. Even if packaging bags undergo rough handling during storage and transport, they will not tear. This safeguards the internal contents of the bags from spoilage.
- PP is a lightweight polymer having good resistance to rodent attacks, microbial and chemical action, and high moisture. These properties make it a cost-effective packaging material.
- Maintenance of the integrity of PP woven bags in high temperature allows the food packaging to be heat sealable.
- It is possible to reuse and recycle the packaging bags made from PP.
- As a sturdy polymer with the possibility of lamination and printing, PP offers appealing packaging solutions. This can help a business develop a unique brand identity.
- The packaging of food items in PP woven sacks increases their shelf life.
Now, PP has become as important as the yellow metal for the food packaging industry. This material, developed by Natta, will stay in use for many generations to come.
