Thermal and Cold Chain Packaging
Thermal and Cold Chain package testing is for products that require a temperature-controlled environment. Common examples of products that may require this type of packaging are pharmaceutical and food products. As is the purpose of most types of package testing, the goal is to prevent product damage throughout the distribution channel. Packages may experience various stresses throughout distribution. The three types of package testing that are typically done for products requiring thermal or cold chain packaging are environmental, altitude, and transit.
Environmental testing is used to observe the effects that temperature and humidity have on products and their packaging. When a temperature-controlled package is shipped through the distribution channels, it may encounter various environments. For example, the package may be in a shipping container that can be a hot, humid atmosphere for an extended period of time. This type of humidity could have warping effects on packaging materials like cardboard. Environmental testing is also used to see how well the cold chain packaging performs in varying temperatures. The package should be able to maintain its integrity and protect the product when subjected to this type of testing. Additionally, temperature and humidity testing are used for preconditioning and conditioning packages prior to conducting other types of package testing. Keystone is equipped with 15 environmental testing chambers ranging in size from small chambers to full walk in rooms. We can accommodate many different products while also delivering fast results.
Altitude testing measures the effects of high altitude and reduced air pressure on packaging. When packages are transported at high altitudes, such as feeder aircraft or ground transportation via high mountain passes, the cabin might not be pressurized. The lack of pressurization at high altitudes can result in package damage like bursting. The package should be able to withstand the pressure and altitude changes without causing damage to the product inside. This is especially important for products that need to remain at a certain temperature throughout transportation. Testing will ensure that a product is fit for transportation regardless of the means of shipping.
Transit testing refers to any type of testing that is relevant to the distribution channel. When products are shipped, they encounter various stresses throughout distribution. Some of the stresses can include drops, shakes, and vibrations. The package testing the we perform is designed to help ensure product safety. Package testing can be used as a preventative measure during design and development. Before having packaging made for an entire product supply, having testing done can help to prevent costly replacement expenses if the packaging does not hold up later on. Especially with cold chain packaging, it is important that the stresses of transportation will not compromise package integrity.
