How to Put Expiry Dates on Products
Accurate and clear product dating is crucial for ensuring consumer safety and maintaining product quality. It involves determining the appropriate date format, choosing between “best before” and “expiry” dates, and implementing effective batch coding systems.
Understanding Expiry Dates and Best Before Dates
Before delving into the specifics of applying expiry dates, it’s essential to differentiate between “expiry date” and “best before” date.
• Expiry date: Indicates the final date a product should be consumed. After this date, the product may pose a health risk.
• Best before date: Suggests the product is at its optimal quality before this date. While it might still be safe to consume after, its flavor, texture, or nutritional value may decline.
The choice between the two depends on the product type and its potential health implications. Perishable items like fresh meat or dairy products typically require an expiry date, while packaged goods often use a best before date.
Determining Product Shelf Life
Accurately establishing a product’s shelf life is fundamental. It involves a combination of scientific testing, industry standards, and consumer feedback. Factors influencing shelf life include:
• Product composition: Ingredients, additives, and preservatives affect product stability.
• Packaging: The type of packaging material and its interaction with the product impact shelf life.
• Storage conditions: Temperature, humidity, and light exposure can accelerate product degradation.
• Microbiological factors: The presence of microorganisms can influence product safety and quality.
Implementing Batch Coding
Batch coding is essential for tracking product history and facilitating recalls if necessary. It involves assigning a unique code to each production run. The code typically includes information about the manufacturing date, time, and location.
Effective batch coding systems:
• Improve product traceability
• Aid in inventory management
• Facilitate quality control
• Enable efficient recall processes
Applying Expiry Dates and Batch Codes
The method of applying expiry dates and batch codes depends on the product and packaging. Common techniques include:
• Direct printing: Printing directly onto the product or packaging using ink or laser technology.

• Labeling: Applying pre-printed labels with expiry dates and batch codes.
• Embossing or debossing: Creating raised or indented characters on the packaging.
• Stamping: Using ink or heat to imprint information onto the product or packaging.
Legal and Regulatory Considerations
Expiry date and batch coding regulations vary by country and product category. It’s crucial to comply with all relevant laws and standards to avoid legal issues and protect consumers.
Key considerations include:
• Clear and legible date formats
• Accurate and truthful information
• Proper placement of expiry dates and batch codes
• Recordkeeping requirements
By carefully considering these factors, businesses can effectively implement expiry date and batch coding systems, ensuring product safety, quality, and consumer confidence.
