Nonbreakables

Nonbreakables is a term used to describe objects that are designed or marketed as resistant to breaking or shattering under ordinary use. The label is commonly applied to consumer products such as drinkware, storage containers, and protective gear, as well as to certain packaging and laboratory equipment. In many cases, nonbreakable denotes high impact resistance rather than an absolute guarantee of invulnerability.

Materials often associated with nonbreakables include polycarbonate, acrylic (PMMA), high‑impact polystyrene, and various engineering plastics such as ABS and PETG. These materials are selected for properties such as toughness, light weight, and, in some cases, optical clarity. They may offer good resistance to drops and impacts, but they can still fail under extreme temperatures, UV exposure, prolonged loading, or manufacturing defects.

Common applications include reusable beverage containers, lunch boxes, safety gear, and industrial or consumer packaging designed to withstand rough handling. In marketing, nonbreakable claims are typically used to convey durability and practicality, though manufacturers often distinguish between "shatter-resistant" or "impact‑resistant" products and items that are truly unbreakable in a literal sense.

Limitations and consumer expectations are important considerations. No material is truly unbreakable; all can fail under sufficient force or over time. Claims of nonbreakability should be substantiated, and in some jurisdictions such claims are regulated to prevent misleading advertising. Proper use, maintenance, and appropriate handling extend the life of nonbreakable products.
