HDPE is more rigid than low-density polyethylene and provides a reliable seal in screw-cap applications. Note that HDPE is not recommended for autoclaving, and compatibility with concentrated oxidizing acids or aromatic and halogenated solvents should be verified before use.\u003c\/p\u003e\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, Caplugs® Evergreen Slide-Fix™ PAP jar screw caps are manufactured under ISO 9001 quality management from BPA-free, phthalate-free, latex-free resin.
