Currently, the industry offers a wide range of biodegradable plastic items. PLA bioplastic is a biodegradable plastic that is utilized in a variety of applications. So, what sort of plastic is this? Let us discover out with Minh Sang Packaging in the article below.

What Is PLA Bioplastic?
PLA bioplastic is a thermoplastic bioplastic derived from plant-based sources such as potato starch, maize starch, sugarcane, cassava tubers, etc. As a result, these forms of packaging are biodegradable and are widely utilized in the production of daily objects such as food packaging, cup trays, bowls, medical tools, food film for vegetable wrapping, etc.
PLA Bioplastic Production Process
The lactic acid polymerization process is used to generate PLA bioplastic. To produce lactic acid, manufacturers ferment sugar using renewable ingredients such as tapioca starch, maize starch, potato starch, and sugar cane.
Next, lactic acid is placed in a reactor where it polymerizes into lactide under vacuum and high temperature conditions. Lactide decomposes into chains and links when exposed to catalysts and high temperatures to form PLA. In the PLA plastic production process, metal catalysts can be used to create waste in intermediary processes.
To improve economic efficiency in the existing production method, scientists utilize zeolite as a catalyst in the reactor to direct the conversion of lactic acid into lactide. At this moment, the metal that causes waste in intermediate phases will be removed.
Benefits and drawbacks of PLA Bioplastic
PLA bioplastic is becoming more and more well-liked because of its green qualities. In addition to being biodegradable, PLA has other exceptional benefits and is derived from renewable resources like sugarcane or maize starch. But in addition to its advantages, this kind of plastic has certain drawbacks that should be taken into account.
Advantages
PLA bioplastic has certain advantages as follows:
- Because PLA bioplastic is made from renewable resources like sugarcane, corn and cassava starches, it is healthy for human health and the environment.
- Decomposed plastic benefits crops and the soil environment. Consequently, waste treatment facilities are applied to crops as microbial fertilizers.
- PLA plastic may break down into carbon dioxide, humus, and water that plants can use without harming the environment if the right circumstances and microorganisms are present.
- Unlike conventional plastics, this kind of plastic does not pollute the environment when it burns because it does not release harmful volatile compounds.
- Only a few months or a few years are needed for PLA to decompose. It can take hundreds or even thousands of years for conventional plastic to decompose.
Drawbacks
In addition to the previously listed benefits, PLA bioplastics have several drawbacks, including:
- Since the factory should be situated close to raw material regions like corn fields, sugarcane, cassava, sugar beets, etc., the manufacturing of this bioplastic depends on a wide range of raw material locations.
- It has been demonstrated that PLA plastic can only biodegrade in industrial processing settings. The quality of recycled plastic will be impacted if improperly handled. Even when combined with recycled components, it will have an impact on the final product’s quality.
- The current PLA output is insufficient to fulfill demand since there aren’t enough PLA producers operating on an industrial scale.
- Plastic is more expensive and technologically complex to produce than polymers derived from fossil fuels.
PLA Plastic’s common uses today
In the packaging field
PLA plastic has numerous notable benefits and is used extensively in the following fields:
PLA bioplastic is utilized in the packaging industry to create trays, food boxes, shrink film for food packaging, bags, plastic cups, and other items. Specifically, PLA that has been treated with bentonite is utilized as packaging because it is resistant to visible light and UV radiation. This kind of plastic packaging is ideal for storing food since it has antibacterial qualities.
In the field of automobiles and transportation
Additionally, many transportation-related units employ PLA composite materials. For example, Toyota uses PLA composite and zinc wire to build replacement tires and conduct research to create floor mats, seats, and handles. The Ford Company makes automobile arches, carpet systems, and other things out of PLA composite.
In agriculture
Using PLA bioplastic to apply biological coatings that effectively speed up fruit ripening on crops is one use for PLA bioplastic. In addition, it keeps plants wet and fertilizer-rich while preventing fungal diseases and weed and pest development. Additionally, this kind of film is weather-resistant.
As a substance for medication delivery
PLA plastic is utilized in drug delivery materials because to its great mechanical strength, biocompatibility and biodegradability. They are also used to administer tetanus, assist diabetic patients in receiving oral insulin sprays, and provide several other medications, among other things.
Techniques for tissue transplantation
Using biological materials, the tissue transplantation technique joins live cells to the scaffold framework. This enables live cells to proliferate and evolve in a variety of ways, aiding in the regeneration of living tissues. In organ transplantation, biological materials that substitute live tissues have advantages. The best option for great efficiency is PLA plastic.
Conclusion
To put it briefly, PLA bioplastic is one of the most widely used polymers since it is safe for consumers and environmentally friendly. For the most committed guidance and assistance, please get in touch with Minh Sang for additional helpful information.
