If your business handles thermal paper, whether it be receipts, kitchen tickets, or labels, Proposition 65 is not just a California issue anymore. Although Prop 65 is a California law, its reach is already stretching nationwide. Many companies are reformulating products or adjusting labeling strategies across the board to meet the standards. Not understanding the rules is not only risky health-wise, but it could also mean fines, lawsuits, or damage to your brand’s reputation.
Let’s break down what Prop 65 is, why it matters for thermal paper, and how retailers and restaurants everywhere can stay compliant.
What Is Prop 65?
Proposition 65, officially called the Safe Drinking Water and Toxic Enforcement Act of 1986, is California’s way of keeping consumers informed about potential exposure to harmful chemicals. The law requires businesses to provide “clear and reasonable” warnings if their products expose consumers to substances known to cause cancer, birth defects, or other reproductive harm.
While it’s a California law, its influence extends far beyond the state. Many national brands and businesses choose to comply everywhere because consistency is simpler than running two different playbooks.
Why Prop 65 Matters for Receipts and Thermal Paper
Here’s where it connects to your day-to-day: thermal paper.
Traditional thermal paper has often used chemicals like BPA and BPS to develop printed text. These substances are on California’s Prop 65 list. That means something as ordinary as handing a customer a receipt or printing a kitchen ticket could technically count as “exposure.”
For retailers and restaurants, that’s a big deal. Customers touch receipts. Employees handle rolls all day. It’s more than compliance, it’s about health and safety.
And it doesn’t stop with receipts. Paper-based touchpoints like order confirmation labels, allergen label information, grab-and-go labels, and nutritional information labels may also be impacted if the wrong media is used.
Prop 65 Compliance Requirements for Businesses
If your receipts, labels, or kitchen tickets contain Prop 65–listed substances, you may need to provide visible warnings. The requirements include:
- Clear communication that a listed chemical is present
- Placement of warnings where customers and employees will see them
- Consistency across all impacted locations
Non-compliance can result in penalties that add up fast. In addition to fines, businesses risk lawsuits and reputational harm, which are two things every operator wants to avoid.
What Prop 65 Means for Retail and Restaurants
Prop 65 compliance is not just a back-office concern. It shows up in everyday touchpoints where customers and staff interact with paper.
> For Retailers
Receipts are the obvious starting point, but compliance extends far beyond the checkout counter. Retailers also rely on:
- Barcode labels for pricing and scanning
- Inventory labels for stock management and traceability
- Product rotation labels to manage freshness and reduce shrink
- Loyalty coupons and promotional tickets handed directly to customers
Each of these is a potential source of exposure if the wrong thermal paper is used.
> For Restaurants and QSRs
Foodservice operations depend heavily on thermal paper for smooth workflows and accurate orders. Prop 65 compliance comes into play with:
- Kitchen tickets that keep back-of-house organized
- Catering labels for large orders and off-premise service
- Weight and serving size labels that provide critical portioning information
- Food identification labels to separate allergen-sensitive items or specialty orders
- Special product offerings labels and nutritional information labels that help guests make informed choices
From grab-and-go stations to off-premise dining, labels are everywhere in modern foodservice. Each printed piece is a small but important part of both compliance and customer trust.
How to Choose Prop 65-Compliant Paper
The solution is simple: choose the right media. Look for thermal paper that is:
- BPA-free and BPS-free (phenol-free)
- Tested for Prop 65 compliance
- Verified by a trusted supplier
The right paper doesn’t just protect your business legally. It also reassures your customers and employees that you take their safety seriously, which makes them feel good about doing business with your brand.
