Package

A package is a container or wrap used to hold goods for storage, transport, sale, or distribution. The term also refers to a bundle of items packaged together for convenience. Packaging serves several purposes: protecting contents from damage, enabling handling and stacking, conveying information (labels, instructions, branding), and facilitating commerce. Packaging materials include paper, cardboard, plastic, glass, metal, and composites, selected for durability, weight, cost, and environmental impact.

In retail and logistics, packaging is commonly divided into primary packaging (the item that directly contains the product), secondary packaging (grouping several items), and tertiary packaging (shipping units such as pallets and crates). Packaging design affects shelf appeal, temperature and moisture protection, shelf life, tamper resistance, and recyclability. Regulations in many jurisdictions govern labeling, hazardous material disclosures, and end-of-life disposal.

In software and computing, a package is a bundle of code, data, and metadata that can be distributed, installed, and managed by a package manager. Packages enable reuse, versioning, and dependency handling. Examples include Python packages (installed with pip), Java packages, Debian or RPM OS packages, and JavaScript packages via npm or yarn. Package managers automate installation, updates, and conflict resolution.

Beyond commerce and computing, "package" may denote a set or bundle of measures, features, or proposals designed to be enacted together, such as a policy package or legislative package. The term emphasizes grouping related elements into a cohesive unit.
