PBAT: A Sustainable Solution for Biodegradable Plastics


As the world shifts towards sustainable materials, PBAT (Polybutylene Adipate Terephthalate) has emerged as a key player in the biodegradable plastics market. This eco-friendly polymer offers the flexibility and durability of traditional plastics while being compostable. In this article, we explore the features, types, and applications of PBAT, along with practical tips for sourcing it from China.


How to Find Reliable PBAT from China in 2025


China is a leading producer of PBAT, offering competitive prices and advanced manufacturing capabilities. To find reliable suppliers, consider platforms like Alibaba, which vet manufacturers for quality and compliance. Look for suppliers with certifications such as ISO 9001 and EN 13432 (for compostability). Request samples to test the material’s performance before placing bulk orders.


What Buyers Should Know Before Buying PBAT from China


When purchasing PBAT, verify the supplier’s production capacity and lead times. Ensure they provide technical data sheets (TDS) and material safety data sheets (MSDS). Negotiate pricing based on volume, and clarify shipping terms (e.g., FOB or CIF). Additionally, confirm the supplier’s experience in exporting to your region to avoid customs issues.


Types of PBAT


PBAT is available in several forms, including:

  • Film-grade PBAT: Used for biodegradable bags and packaging.
  • Injection-grade PBAT: Suitable for rigid products like cutlery.
  • Blended PBAT: Combined with PLA or starch for enhanced properties.

Functions and Features of PBAT


PBAT combines the best of synthetic and biodegradable materials. Key features include:

  • High flexibility and tear resistance.
  • Compostable under industrial conditions (meets ASTM D6400).
  • Compatible with other biopolymers like PLA.

Scenarios of PBAT


PBAT is widely used in:

  • Food packaging (e.g., compostable bags).
  • Agricultural films (biodegradable mulch).
  • Disposable cutlery and tableware.

How to Choose PBAT


Select PBAT based on:

  • Application: Film-grade for packaging, injection-grade for rigid items.
  • Certifications: Ensure compliance with local biodegradability standards.
  • Supplier reputation: Check reviews and request references.
