Did you know: Apple's earth-friendly packaging comes from the Swedish forests

For iPhone 8, this meant pursuing an alternative to a polypropylene wrap that protected the power adapter. Finding a fiber alternative proved challenging since fiber naturally expands and contracts with changes in humidity. The significant number of suppliers and locations through which the power adapter wrap would pass made controlling the humidity of the environment impossible. This required Apple to take a very hands-on approach, working directly with the supplier to alter aspects of the manufacturing process to create a fiber wrap that would meet technical needs. While the power adapter wrap is a small piece of the iPhone packaging, it represents a significant amount of material given the number of iPhone units sold.
