The testing is usually product specific: the mechanisms of degradation are often different. Exposures to expected and elevated temperatures and humidities are commonly used for shelf life testing. The ability of packaging to control product degradation is frequently a subject of laboratory and field evaluations. The ability of a package to control the permeation and penetration of gasses is vital for many types of products.

Tests are often conducted on the packaging materials but also on the completed packages, sometimes after being subjected to flexing, handling, vibration, or temperature. Degradation of Packages[ edit ] Packages can degrade with exposure to temperature, humidity, time, sterlization steam, radiation, gas, etc. For some types of packaging, it is common to test for possible corrosion of metals, polymer degradation , and weather testing of polymers.

Several types of accelerated aging of packaging and materials can be accomplished in a laboratory. Exposure to elevated temperatures accelerates some degradation mechanisms.

An Arrhenius equation is often used to correlate certain chemical reactions at different temperatures, based on the proper choice of Q10 coefficients. As with any laboratory testing, validating field trials are important.

This can be to: Determine the ability of packages to withstand low pressures that might be encountered. Package integrity and product protection are important packaging functions.

Tests are conducted to measure the resistance of packages and products to controlled laboratory shock and impact. Testing also determines the effectiveness of package cushioning to isolate fragile products from shock. Instrumentation is used to measure the shock transmitted to a cushioned product.

The ability of insulated shipping containers to protect their contents from exposure to temperature fluctuations can be measured in a laboratory. The testing can be of empty containers or of full containers with appropriate jell or ice packs , contents, etc. Ovens, freezers, and environmental chambers are commonly used for this and other types of packaging.

Digital temperature data loggers are used to measure temperatures experienced in different distribution systems. This data is sometimes used to develop unique laboratory test methods for that distribution system. One method of testing involves rapid movement from cold to hot water baths, and back.

Packaging evaluations are an important part of marketing research. Legibility of text on packaging and labels is always subjective due to the inherent variations of people. Efforts have been made to help better quantify this by people in a laboratory: still using people for the evaluation but also employing a test apparatus to help reduce variability.

Some test procedures call for a judgment by test engineers whether or not pre-established acceptance criteria have been met. The measured performance of many packages is affected by the conditioning and testing atmospheres. For example, paper based products are strongly affected by their moisture content: Relative humidity needs to be controlled. Plastic products are often strongly affected by temperature.

Engineering tolerances for the conditions are also specified. Often the package is conditioned to the specified environment and tested under those conditions.

This can be in a conditioned room or in a chamber enclosing the test. With some testing, the package is conditioned to a specified environment, then is removed to ambient conditions and quickly tested. The test report needs to state the actual conditions used.

Engineers have found it important to know the effects of the full range of expected conditions on package performance. This can be through investigating published technical literature, obtaining supplier documentation, or by conducting controlled tests at diverse conditions.

This is particularly important for foods, pharmaceuticals, some chemicals, and a variety of products. The testing is usually product specific: the mechanisms of degradation are often different. Exposures to expected and elevated temperatures and humidities are commonly used for shelf life testing.

The ability of packaging to control product degradation is frequently a subject of laboratory and field evaluations.

The use of a log-normal distribution is often suggested but this requires the drop height increment to be a constant based on the logarithms of the drop height, thus the actual drop height increment would change with the drop height.
