Product Description
What Is Polylactide (PLA)?
Polylactide (PLA), also known as polylactic acid, is a bio-based thermoplastic polyester produced from lactic acid derived from renewable feedstocks such as corn, sugarcane and cassava. PLA combines processability, stiffness and transparency with the potential for industrial compostability under appropriate conditions, making it useful for sustainable packaging, film, textiles and additive manufacturing.
PLA is available in multiple grades that differ in MFR, L-isomer content, melting point and mechanical properties. This allows formulators to select the right grade for their specific process — whether injection molding, blown film, cast film, fiber spinning, melt blown nonwoven or 3D printing filament extrusion.

Product properties
Bio-Based Feedstock
PLA is produced from renewable feedstocks such as corn starch, sugarcane and cassava, reducing reliance on petroleum-based raw materials.
Compostability and End-of-Life
PLA can be compostable under appropriate industrial composting conditions, depending on the PLA grade, product formulation, article thickness, processing conditions and applicable certification requirements. Compostability should therefore be evaluated against the intended application and relevant standards (e.g., EN 13432, ASTM D6400) rather than treated as universal degradation in natural environments.
Thermoplastic Processability
PLA is a thermoplastic polyester that can be processed by injection molding, blow molding, thermoforming, film extrusion and fiber spinning using equipment commonly used for conventional plastics.
Physical Properties
PLA offers good stiffness, transparency and dimensional stability. Density is approximately 1.24 g/cm³, melting point 150–180°C depending on grade, and glass transition temperature 55–65°C.
Hygroscopicity
PLA is moderately hygroscopic and should be dried before processing. Recommended moisture content for extrusion is typically below 0.025%.
Specialty Application
Polylactide (PLA) Resin for Biodegradable & Compostable Bubble Film
Can PLA be used for bubble film? Yes. Our WIT 102 and WIT 103 grades (MFR 3 g/10min) are specifically developed for blown film and casting film applications, making them suitable for biodegradable and compostable bubble film, bubble wrap and protective packaging. Formulators can blend these grades with PBAT or other biodegradable polyesters to balance stiffness, flexibility, melt strength and film clarity.
For bubble film applications, the key parameters to confirm are MFR, melt strength, elongation, tensile strength, film clarity and compatibility with your existing extrusion equipment. If you are developing a compostable bubble wrap formulation, contact us with your target film thickness, bubble size and required compostability certification (e.g., EN 13432, ASTM D6400) — we will recommend the appropriate PLA grade and blending ratio.
Recommended grades for bubble film: WIT 102 (MFR 3, blown film / double drawn film), WIT 103 (MFR 3, blowing film / casting film). Both grades can be blended with PBAT, PPC or other compostable polyesters to adjust flexibility and toughness.
Main Applications
Applications of Polylactide (PLA)
1. Sustainable Packaging & Compostable Film
PLA is widely used for compostable packaging film, bubble film, bubble wrap, food containers, bags and flexible packaging. Its ability to break down in industrial composting environments makes it a preferred choice for brands seeking to reduce reliance on conventional petroleum-based plastics.

What Should Buyers Check When Sourcing PLA Resin?
Before ordering bulk PLA resin, B2B buyers should confirm the following with any supplier:
- What PLA grade is suitable for your processing method — blown film, cast film, injection molding, fiber spinning or 3D printing?
- What MFR range do you need? Confirm MFR is tested at 190°C / 2.16 kg and is consistent batch-to-batch.
- Can the PLA be blended with PBAT, PPC or other compostable polyesters for your target film or bubble wrap formulation?
- What is the L-isomer content? Higher L-isomer gives higher melting point and stiffness.
- Is TDS, SDS and batch-specific COA available for every shipment?
- What packaging sizes are available? 25 kg bags for trials, 1000 kg jumbo bags for production.
- Can you supply samples for formulation trials before bulk ordering?
- Can PLA specifications be customized (MFR, L-isomer, additives) for your specific application?
Frequently Asked Questions (FAQ)
Q1: What is Polylactide (PLA)?
A1: Polylactide (PLA), also known as polylactic acid, is a bio-based, biodegradable thermoplastic polyester produced from renewable feedstocks such as corn starch, sugarcane or cassava. It is used in sustainable packaging, compostable film, textiles, nonwoven fabric, 3D printing and injection-molded disposables.
Q2: Is Polylactide the same as Polylactic Acid?
A2: Yes. “Polylactide” and “polylactic acid” refer to the same polymer. “Polylactide” is the more technically accurate term for the polymerized form, while “polylactic acid” is the more common commercial term. Both refer to PLA.
Q3: What is the CAS number of PLA?
A3: The CAS number for Polylactide (PLA) is 26100-51-6. Different stereochemical forms (PLLA, PDLLA, PDLA) may have different CAS numbers. Please confirm the specific grade with our sales team before ordering if your application requires a specific regulatory reference.
Q4: Is PLA suitable for sustainable packaging?
A4: Yes. PLA is widely used for sustainable packaging including compostable film, bubble film, bubble wrap, food containers and flexible packaging. Compostability depends on grade, article thickness and the applicable certification (e.g., EN 13432, ASTM D6400).
Q5: Can PLA be used to make compostable bubble film?
A5: Yes. Our WIT 102 and WIT 103 grades (MFR 3 g/10min) are suitable for blown film and casting film applications including compostable bubble film and bubble wrap. PLA is often blended with PBAT or other biodegradable polyesters to balance stiffness, flexibility and melt strength.
Q6: What PLA grade is suitable for film extrusion?
A6: For blown film and cast film, WIT 102 and WIT 103 with MFR around 3 g/10min are recommended. Final grade selection should consider film thickness, bubble stability, target mechanical properties and blending requirements.
Q7: Can PLA be blended with PBAT for compostable film?
A7: Yes. PLA is commonly blended with PBAT to improve flexibility, toughness and tear resistance while maintaining compostability. Typical PLA/PBAT ratios depend on the target application, film thickness and required mechanical properties.
Q8: Is PLA industrially compostable?
A8: PLA can be compostable under appropriate industrial composting conditions, depending on grade, article thickness and certification. It does not degrade quickly in natural environments or home compost. Buyers should confirm the applicable standard (EN 13432, ASTM D6400) for their target market.
