Hanoi University of Technology successfully researched self-destructing plastic bags made from cassava flour

Polymo Materials Research Center of Hanoi Polytechnic University has successfully researched self-destruct, durable and tougher plastic bags than normal plastic bags, made from cassava flour but the price is only 1.5 times higher.

Using plastic bags is now a problem that makes environmental experts headache to find solutions. The use of replacement bags with paper or biodegradable materials is currently ineffective because of their cost and convenience level cannot be compared with traditional plastic bags enough for people to change themselves. Daily use habits.

Recently, scientists from the Polymer Research Center of Hanoi University of Technology have successfully fabricated a type of plastic bag made from cassava flour combined with bio-plastics , supposedly the product can replace the persistent plastic bags on the market today.

This new bag has greater durability, tougher than normal plastic bag.(Illustration).

According to the test results, this new bag has greater durability, tougher than normal plastic bag. The main material for making bags is from cassava flour, combined with bio-plastics, so the price is not too high, only 1.5 to 2 times bigger than traditional plastic bags. And because it is made of eco-friendly biological materials, after use, this bag can be buried and decomposed like normal biological waste.

The amount of cassava flour used when producing this bag will account for 35-40%, the rest is biodegradable plastic. And with durable characteristics, environmentally friendly but the production cost is not so expensive, researchers of Hanoi University of Technology are expected to produce and sell this type of product to the market. domestic as well as serving the need to export abroad.

In fact, in the world and in Vietnam, there have been many successful researches on using starch to produce environmentally friendly plastic bags. For example, in 2017, Nguyen Cam Kieu Thanh and Nguyen Cam Binh Minh used cassava starch together with nano silver to create a bag that is antibacterial, durable and tough but still biodegradable when taken away. bury.

Or as in some other countries around the world, potatoes have been used as a source of starch to produce organic plastic bags, biodegradable in nature. However, most of these inventions have not yet solved the cost and price problem to an acceptable level as researched by Hanoi University of Technology.
