Polylactic Acid (PLA) Services
Polylactic acid (PLA) is a biobased thermoplastic polyester derived from renewable resources such as corn starch, sugarcane, and cassava. It is formed through the polycondensation or ring-opening polymerization of lactic acid monomers, resulting in long-chain polymers with excellent biocompatibility, biodegradability, and thermoplastic processability. In biomimetic materials research, PLA has become a key foundational material in tissue engineering scaffolds, biomimetic membranes, drug delivery carriers, and bone and soft tissue repair due to its safety, controllable degradation, and versatile processing methods. BOC Sciences has extensive experience in the custom synthesis and development of PLA, offering control over molecular weight, crystallinity, and stereochemistry, while supporting copolymer modification, functionalization, and composite formation with natural polymers or nanoparticles. Combined with processing technologies such as 3D printing and electrospinning, as well as characterization techniques including GPC, DSC, and SEM, we ensure PLA materials have stable and controllable properties suitable for scaffolds, films, particles, coatings, and other biomimetic material formats, enabling efficient translation from R&D to industrial application.

FAQs
Frequently Asked Questions
Is PLA actually plastic?
Polylactic acid (PLA) is a biodegradable thermoplastic. Although derived from natural sources such as corn or sugarcane, it possesses the physical characteristics of plastics. PLA can be processed by injection molding, extrusion, or 3D printing and is widely used in packaging, films, scaffolds, and biomimetic material development, offering both environmental friendliness and processing versatility.
Is PLA 100% biodegradable?
PLA is biodegradable, but complete degradation in natural environments requires specific conditions, such as industrial composting (high temperature and humidity). Under these conditions, PLA can be broken down by microorganisms into water and carbon dioxide. Its degradation performance can be adjusted via molecular weight, crystallinity, and copolymer modification, making it suitable for biomimetic scaffolds, medical films, and degradable packaging materials.
Is PLA natural or synthetic?
PLA is a semi-synthetic polymer produced by chemically polymerizing or ring-opening polymerizing lactic acid derived from natural sources. Although the raw materials come from plants such as corn or sugarcane, synthesis allows control over molecular weight and crystallinity, giving PLA excellent mechanical properties, degradation rates, and processing adaptability for biomimetic and medical applications.
Which natural materials is PLA made from?
PLA is primarily derived from starch-containing plants such as corn, sugarcane, and cassava. Lactic acid is produced through fermentation and then chemically polymerized or ring-opening polymerized to form PLA. These natural sources ensure renewability and biodegradability, making PLA suitable for eco-friendly plastics, degradable packaging, and biomimetic scaffolds and tissue engineering materials.
What is polylactic acid used for?
PLA has broad applications in degradable packaging, disposable tableware, 3D printing filaments, and biomimetic material research. It can be fabricated into scaffolds, films, nano/microparticles, hydrogels, and coatings for use in tissue engineering, drug delivery, and wound repair. PLA combines environmental benefits with excellent processing properties, making it ideal for research and industrial development.
What are the biomedical applications of polylactic acid?
PLA is widely used in the biomedical field for tissue engineering scaffolds, biodegradable surgical sutures, drug-controlled release carriers, and wound repair membranes. Molecular weight, crystallinity, and functional modifications can be tuned to match mechanical properties with degradation rates, supporting bone, soft tissue, and vascular engineering, and enhancing biocompatibility and controlled degradability for biomimetic materials and medical device applications.
How is lactic acid manufactured?
Lactic acid is typically produced by fermenting starch-rich plants such as corn, sugarcane, or cassava, followed by chemical or enzymatic purification. During fermentation, microorganisms convert sugars into lactic acid, which can then be purified, concentrated, and lactonized to produce PLA feedstock. This process ensures renewable lactic acid sources while providing reliable raw materials for PLA custom synthesis, molecular weight control, and functional development.
