Polylactic acid (PLA) - Resin

PLA

Polylactic acid (PLA) is a biodegradable and bio-based polymer obtained biotechnologically from renewable resources. It belongs to the polyester family and is produced by the polymerization of lactic acid monomers.

ADVANTAGES AND PROPERTIES OF PLA:

Biodegradable and compostable:

PLA is environmentally friendly as it is derived from renewable resources such as corn starch, sugar cane or other plant materials. It is biodegradable under suitable conditions and breaks down into natural compounds such as carbon dioxide and water. PLA is also compostable, which means it can be broken down in industrial composting plants.

Renewable resource:

PLA is fermentatively produced from renewable raw materials, which reduces dependence on fossil raw materials. This makes PLA an attractive alternative to conventional petroleum-based plastics.

Transparency and gloss:

PLA has a similar transparency and gloss to conventional plastics such as polyethylene (PE) or polyethylene terephthalate (PET). This property makes PLA suitable for applications that require transparency, such as food and beverage packaging.

Versatility in processing:

PLA can be processed using conventional plastic processing methods such as injection molding, extrusion, blow molding and thermoforming. It can be produced in various forms, including films, fibers, foams and thermoformed products.

APPLICATIONS:

Packaging:

PLA is widely used in packaging applications, including containers, trays, films and disposable tableware. Due to its transparency, gloss and barrier properties against moisture and oxygen, it is suitable for food packaging.

Textiles and nonwovens:

PLA fibers can be used in textiles, including clothing, upholstery and bedding. Nonwovens made from PLA are used in wet wipes, diapers and medical products.

Biomedical applications:

PLA is used in various biomedical applications such as surgical sutures, drug delivery systems and templates in tissue engineering. Due to its biocompatibility and biodegradability, it is suitable for temporary implants.

3D printing:

PLA is a popular material for 3D printing because it is easy to process, biodegradable and available in a variety of colors.

Agricultural films:

PLA films are used in agriculture for mulching, greenhouse covers and soil stabilization. These films degrade naturally, reducing the environmental impact compared to conventional plastic films.

PLA is one of the most important bioplastics on the market and offers a renewable and biodegradable alternative to conventional plastics. Ongoing research and development is expanding its applications and improving its properties for various industries.
