Shelf Life of Packaged Products

Shelf life is the period during which a packaged product remains safe, stable and acceptable under specified storage conditions. PCRI helps food and pharmaceutical companies determine it, and the packaging that protects it.

Pharmaceutical blister packs

The Key Principle

Shelf life is never a property of the product alone. It depends on the product, the packaging around it and the conditions it is stored in.

Major Factors

These are the factors that decide how long a packaged product lasts.

  • Product characteristics
  • Packaging barrier properties
  • Temperature and humidity
  • Oxygen, moisture and light
  • Microbial and chemical stability

The Role of Packaging

Packaging protects the product from the five things that shorten its life.

  • Moisture
  • Oxygen
  • Light
  • Contamination
  • Physical damage

How Shelf Life Is Determined

Three approaches, used alone or together depending on the product and how quickly an answer is needed.

Method 1

Real-time testing

The packaged product is stored under its normal conditions and checked over its full intended life.

Method 2

Accelerated shelf-life testing

Raised temperature and humidity are used to estimate shelf life in a shorter time.

Method 3

Packaging performance tests

WVTR, OTR, seal strength and leakage tests measure how well the packaging itself protects the product.

Plan a Shelf-Life Study

Share the product, the packaging and where it will be sold. We will suggest the right combination of tests.
