PLGA Film/Membrane Preparation
PLGA films or membranes are thin-film materials prepared from poly(lactic-co-glycolic acid) (PLGA). PLGA is a biodegradable and biocompatible polymer whose degradation products are lactic acid and glycolic acid, which can naturally break down into carbon dioxide and water through metabolic pathways. This property makes PLGA widely used in biomedical applications, tissue engineering, and drug delivery. PLGA films/membranes offer excellent mechanical strength, flexibility, and controllable degradation properties and can be fabricated with varying thicknesses and pore structures. These films can serve as drug carriers, tissue scaffolds, protective barriers, or biomedical materials, meeting diverse research and clinical needs. BOC Sciences provides professional PLGA film/membrane preparation and development services, dedicated to delivering high-performance biomimetic material solutions for research institutions and industrial clients. We can customize PLGA copolymer ratios, film thickness, porosity, and functional design, enabling a wide range of applications from drug-controlled release films to tissue engineering scaffolds. By precisely controlling film structure, surface properties, and degradation rate, our services support research innovation and industrial applications, ensuring every batch of PLGA film materials is consistent, reliable, and performance-controlled, providing solid support for biomimetic material development.

FAQs
Frequently Asked Questions
What is a PLGA film/membrane?
PLGA films/membranes are thin-film materials made from PLGA copolymers, composed of lactic acid and glycolic acid in varying ratios. They offer tunable degradation rates and excellent mechanical properties and are used for drug delivery, tissue engineering scaffolds, biomimetic material development, and medical device coatings. Films are generally uniform and continuous, suitable for drug release or coverage, while membranes emphasize porosity and mechanical support for tissue engineering.
What is the typical degradation time for PLGA membranes?
Degradation is highly tunable depending on the LA/GA ratio and molecular weight, ranging from several days to months. Higher LA content slows degradation for long-term support, while higher GA content accelerates degradation for short-term applications.
What types of drugs can PLGA membranes carry?
PLGA membranes can load small molecules, peptides, proteins, and nucleic acids for localized or targeted delivery. Optimizing structure, porosity, and composites allows controlled release and protects drug activity.
How is membrane porosity controlled?
Porosity can be regulated via fabrication method, solvent type, fiber diameter, or gas foaming techniques to achieve dense, porous, or nanofibrous structures. High porosity facilitates drug diffusion and cell adhesion, while low porosity enhances mechanical strength and controlled release.
Can PLGA membranes be combined with other materials?
Yes, they can be combined with natural polymers (gelatin, chitosan, PEG) or inorganic materials (hydroxyapatite, growth factors). Composite membranes enable drug release, antibacterial properties, or enhanced cell adhesion, improving bioactivity and performance.
Does BOC Sciences provide functionalized customization?
Yes, we offer customized functional PLGA membranes including antibacterial, smart responsive, porous tissue engineering, and drug-loaded films. We tailor structure, porosity, degradation rate, and functional design according to client needs, providing full technical support and performance validation for research and industrial applications.
