They feature a strong adhesive and a semi-gloss finish for a professional appearance that remains attached during transit. This option is ideal for products like cosmetics, spices, or tiny bottles where space is limited. Best for startups and small businesses seeking economical bulk labeling on compact containers.

Best for product displays and storefronts, this durable aluminum sign is designed to resist weather and corrosion. The 4-0 aluminum construction, rounded corners, and lamination make it suitable for outdoor use and high-traffic areas. Choose this if you need a long-lasting, high-visibility warning sign for shelves, entryways, or packaging stations. Limitation: larger size requires more space and may not fit every packaging scenario.

Best for standard packaging use, these 2×1 inch labels come on a perforated roll for quick peeling and application. They offer strong adhesive to stay affixed on diverse surfaces like cups, jars, and bags, and align with 2026 Prop 65 requirements. They are well-suited for general product packaging lines that require consistent labeling. Caution: ensure the roll is stored away from high heat to preserve adhesive effectiveness over time.

Best for visibility in public-facing areas, these bilingual English/Spanish Prop 65 stickers are large and easy to read. The 4″ x 4″ size suits storefront windows, vehicle signage, and interior doors. Made from durable vinyl with weather resistance, they perform well indoors and outdoors. Limitation: larger size may consume more label space on small packages; plan surface area accordingly.
Prop 65 California Warning Labels 500 Count Roll, 1 by 2 Inch
Best for shipping and larger packaging, this 1×2 inch label format balances readability with compact packaging needs. The roll includes perforations between labels for easy separation, and the 2026 edition text ensures regulatory alignment. Consider this option for medium-sized cartons, cardboard boxes, and poly mailers. Limitation: slightly larger than ultra-compact labels, may require slight layout adjustment on tight packaging.
Buying Guide: Key Considerations for Prop 65 Warning Labels
What size is right for my packaging?
Choose labels that fit your product surface without covering essential information. Smaller labels work well for jars, bottles, and sachets, while larger formats are better for boxes, bags, and displays.
What surface will the label adhere to?
Consider label material and adhesive quality. Vinyl and laminated options resist moisture and handling; ensure the adhesive is compatible with plastics, glass, cardboard, or metal depending on your packaging.
Do I need bilingual messaging?
In California, bilingual labels (English and Spanish) can improve comprehension. If your customer base includes Spanish speakers, bilingual stickers help ensure the warning is readily understood.
Is the label compliant with the 2026 edition?
Verify that the label text includes Prop 65 warning language and directs readers to the official P65Warnings.ca.gov website, aligning with the most recent edition requirements.
What about durability and placement?
For outdoor or high-traffic areas, opt for laminated or aluminum signs that resist weather and abrasion. For product packaging, choose self-adhesive labels with durable finishes to endure shipping and handling.
