Biodegradable plastic bag material - PLA

With the introduction of the plastic ban, various new biodegradable plastic bags have emerged, the most representative of which is PLA biodegradable plastic bags. Today, Shunxingyuan, a professional flexible packaging manufacturer, will talk about some small knowledge about the biodegradable plastic bag material PLA.

First of all, biodegradable plastic bags refer to those that, in natural environments such as soil and /or sand, and/or under specific conditions such as composting, anaerobic digestion, or in aqueous culture, are degraded by naturally occurring microorganisms such as bacteria, fungi, and algae, and ultimately completely degraded into carbon dioxide (CO2) or/and methane (CH4), water (H2O), mineral salts of the contained elements, and new biomass plastics bags.

Polylactic acid (PLA) is a new type of biological degradable plastic bag material made from starch raw materials derived from renewable plant resources (such as corn). It has good biodegradability and can be completely degraded by microorganisms in nature after use, ultimately producing carbon dioxide and water without polluting the environment. This is very beneficial for environmental protection and is a recognized environmentally friendly material. It is understood that PLA accounts for 45.1% of biodegradable plastics, making it the undisputed leader!

In biodegradable plastic bags raw materials, polylactic acid ( PLA ) is considered one of the most promising varieties, with biocompatibility, biodegradability, and resource renewability. PLA In natural environments, its waste can be degraded through hydrolysis and a series of biological metabolic processes ( 6-12 months) into CO2 and H2O, which can then be used by plants in photosynthesis to produce starch, and the starch can then be used to produce polylactic acid. Therefore, polylactic acid is not only an inexhaustible material, but it can also reduce white pollution, save petroleum resources, and is a material that can maintain the "carbon cycle balance" in nature, so biodegradable plastic bags its application and promotion also saves energy and reduces emissions and pollution.

With the continuous progress of polylactic acid synthesis technology and the continuous reduction of production costs, it has gradually entered the civil engineering materials field of aircraft and automobile interiors from the biomedical and daily necessities fields, and currently has the largest market share. The latest research report on biodegradable plastics chemistry states that polylactic acid currently accounts for approximately 47% of global biodegradable plastic demand, and is very likely to become one of the substitutes for petroleum-based plastics, biodegradable plastic bags making it the best alternative to ordinary plastic bags.

However, some defects of polylactic acid hinder its further application, such as PLA its weak heat resistance, relatively easier hydrolysis, and certain weaknesses in impact resistance and post-processing, limiting its range of applications. However, with the improvement of preparation levels, these problems are gradually being solved. As a new-age plastic material, PLA applications are becoming increasingly mature. By mixing with other molecules, PLA resins with special properties can be obtained. Currently, personal computer casings and 3D printing are promising PLA application markets.
