LDPE

A flexible commodity plastic for molded parts that need to bend and flex without cracking.

Example: molded LDPE

What is it?

A soft, highly flexible commodity plastic, the opposite end of the polyethylene family from rigid HDPE.

Key behavior

Extremely flexible with strong impact resilience — bends rather than cracks.

Why choose it

Parts that need genuine flexibility — squeeze bottles, flexible lids, tubing.

Applications

Squeezable containers, snap-on lids, flexible tubing, living hinges.

Processing notes

High shrinkage rate — tooling must be designed around its flexible, low-density nature.
