PLA (polylactic acid) is a plant-based plastic often seen as an eco‑friendly alternative to traditional petroleum plastics. But is it truly biodegradable? The answer depends on how it’s disposed of.

The circular carbon economy treats carbon as a resource, not just a waste problem. Instead of the old linear model (extract → burn → emit), this approach keeps carbon in a closed loop using the 4R framework: Reduce, Reuse, Recycle, and Remove.

Have you ever looked at a plastic bottle cap, a car dashboard trim, or a medical syringe and wondered how it was made? Most likely, it was injection molded. Injection molding is the most common manufacturing process for producing high‑volume plastic parts — and for good reason. It’s fast, repeatable, and capable of creating complex geometries with tight tolerances.

Choosing the wrong plastic material can lead to premature failure, regulatory issues, or unnecessary cost. With hundreds of resin grades available, how do you make the right choice? At MEITU, we guide customers through material selection based on three key factors: mechanical requirements, environmental exposure, and regulatory compliance.
