What Is It?
NEXXALENE™ Unfilled PP Co-Polymer Compound, the same grade used broadly across household containers and packaging.
How It's Manufactured
PP is compounded with stabilizer additives on a standard line; food-contact grades are formulated without additives that would migrate into stored contents.
Manufacturing Process for This Application
Containers, jars, and bottles are injection or blow molded from PP pellets, relying on the resin's excellent hinge properties for integrated snap-fit or living-hinge lids that need to flex thousands of times without cracking.
Why Polymer Choice Matters Here
A container lid opened and closed daily needs a polymer that tolerates repeated flexing at a thin hinge point without fatigue-cracking — PP's hinge properties are specifically why it, rather than a stiffer engineering resin, dominates this category.
Why This Compound Is Suited
"Trays, Bottles, Jars, Containers" are explicitly listed applications for this grade.
Nexxa Compounds is a leading manufacturer of PP compounds for kitchen storage container applications in India, supplying some of the largest manufacturers across India and internationally.
