Biopolymer – Masterbatch that is friendly to the environment

From the trend of limiting the use of non-biodegradable products, bio plastic was created to meet the needs of civilized users as well as to solve pollution problems. As consequences to the appearance of bio plastic, Biopolymer– one of the raw materials for making bio-plastics is also received a lot of attentions.


Biopolymer overview and the demands on bioplastic

Biopolymer is an indispensable material involving in the production of plastic products that do not harm the environment. In recent years, when the alert on environmental problems is constantly chattering, solutions to improve the environmental situation have been increasingly developed. To improve this situation, bioplastics are a great solution being used by many countries around the world.

The emergence of bio-plastic and filler masterbatch partly solves the problems of environmental pollution

Before learning about biopolymer products, we need to learn about bioplastics. In fact, bio-plastic was invented in the early 20th century by the French scientist Maurice Lemoigne. But at that time, when the industrial revolutions broke out, people preferred simple technologies that have high productivity in order to generate large amount of products and brought considerable profits. Bioplastic was not one of them hence it did not receive much attention. Until the 21st century, when plastic products were gradually restricted and crude oil prices fluctuated constantly, bioplastic was used more and more. Why? Because compared to synthetic resin made from crude oil, the plastic made from organic matter such as corn, starch, straw, etc. is very friendly to the environment because of it is easily decomposed and carbon emissions released in the process of manufacturing is also very low.

In the plastic and filler masterbatch industry, bioplastic is a very popular material because it contains polylactide (PLA) in its compositions. This compound is an organic substance that is easily found in vegetables. Therefore, bio plastic is easily degradable in a short time. PLA plastic is composed of polymer chains, so it is quite similar to PET plastic (with petroleum components). PLA resin and bioplastic plastic in general have good toughness, durability and flexible malleability like other virgin and synthetic plastics.

From this biodegradability of bioplastic, manufacturers have developed a new material called biopolymer. These are not similar to the conventional calcium carbonate filler in the way they have the advanced biological benefits for environmental protection purposes. Bio filler is used in disposable plastic products so that they can biodegrade in a short time after used.

Similar to other filler masterbatch products, Biopolymer is a type of filler for plastic in granular shape with a major component of CaCO3 and bio-plastic bio resin. The  Biopolymer is compatible with PLA, PBS, PBAT, and TBS resins at a rate of 10-20%. Thus, plastic products containing Bio filler are capable of decomposing for several months if treated by specialized waste treatment. Without those catalytic treatments, under natural conditions their destructing time is longer, lasting for several years.

Biopolymer can participate in the process of producing plastic objects by various methods such as injection molding, extrusion, blowing film, etc. to create bio-plastic products shaped like customers want.
