What paper stocks can I choose for warning labels?

Warning labels have to stay legible for the life of the product, so the stock should match the environment they will live in. You can choose from a broad set of materials.

• Matte and gloss paper: Economical choices for indoor equipment and packaging.
• High-gloss: Extra shine and a bit more surface protection.
• BOPP (waterproof): Resists water, oils, and humidity for durable outdoor use.
• Vinyl: Tough and flexible for curved or high-wear surfaces.
• Kraft: A natural look where a rugged aesthetic fits.

For labels exposed to chemicals, moisture, or sunlight, a waterproof synthetic stock paired with the right adhesive is the most reliable choice.
