About Spearlabel

Spearlabel is an independently operated reference publication about label materials, bottle decoration and labeling technology. It is written for packaging designers, converters and people defining the label and container requirements of a packaging line.

This publication is not operated by, affiliated with or endorsed by Spear, Constantia Flexibles, any successor business, or the companies and people that previously used spearlabel.com. It does not manufacture labels or equipment, sell products, provide quotes or act as a purchasing intermediary.

The editorial method is to compare public technical documentation, identify the conditions behind each claim, and turn that information into explanations and checklists. Published sources and access dates accompany substantive technical claims. Historical examples are dated and attributed; they are not our projects or customer experience.

We distinguish material properties from complete label constructions, illustrations from measured results, and selection questions from validated process settings. We do not invent tests, performance figures, professional credentials or compliance claims. Read the editorial policy for sourcing and corrections.
