The packaging market offers an array of packaging solutions tailored to the pharmaceutical industry, each designed to address distinct temperature requirements and environmental conditions. The most common types of cold temperature controlled packaging include:
1) Insulated Shipping Containers
Insulated shipping containers are a packaging solution that uses materials like Styrofoam or polyurethane to create a barrier between the product and the environment. These materials possess low thermal conductivity, meaning they neither conduct heat nor cold readily. This feature helps in maintaining a stable temperature within the container.
Insulated containers are available in various shapes and sizes to accommodate different quantities of products. They are designed to maintain a specific temperature range for a limited duration, typically lasting from several hours to a few days. They are commonly used for short-term storage or transportation of temperature-sensitive products, including vaccines, medicines, and medication samples, and are often paired with refrigerants to further enhance temperature control.
2) Refrigerants
Refrigerants are cooling materials that are used in temperature-controlled packaging to keep the product at the required temperature during transport. These materials absorb heat and help to maintain the desired temperature during shipping.
Refrigerants come in different forms, including gel packs and dry ice, and are chosen based on the product's temperature requirements and the expected shipping time. Gel packs are plastic pouches filled with a gel-like substance that can be cooled to a specific temperature and then used to maintain the temperature of the product during shipping. They are often used for short-duration shipments and are available in different sizes and shapes to accommodate different product quantities.
On the other hand, dry ice is made from a unique substance and is suitable for preserving products at extremely low temperatures. They are better suited for long-duration shipments and, like gel packs, come in various shapes and sizes.
3) Refrigerated Containers
Refrigerated containers are a type of packaging solution that is larger than insulated boxes and are specifically designed to maintain a specific temperature range for an extended period of time, usually spanning from several days up to a few weeks. These containers are primarily used for long-term storage or transportation of temperature-sensitive products, such as blood products or clinical trial samples. They are also referred to as active packaging solutions because they often come equipped with a refrigeration unit that is powered by electricity or another energy source to maintain the necessary temperature range.
4) Passive Thermal Packaging
Passive thermal packaging is a type of packaging solution that does not require external power or refrigeration to maintain the temperature of the product. These solutions are often used for short-term storage or transport of products that need to be kept at specific temperatures. Examples of passive thermal packaging include thermal blankets or pouches that are activated by adding water or other liquids to maintain the desired temperature range.
5) Vacuum Insulated Panels
Vacuum insulated panels (VIPs) have emerged as a highly popular packaging solution for cold temperature control. These panels consist of a core material, such as fiberglass, which is encased in a vacuum-sealed panel. The vacuum-sealed construction of VIPs helps to reduce heat transfer, resulting in superior insulation performance when compared to conventional foam or other insulating materials.
VIPs are commonly used in combination with other cold temperature-controlled packaging solutions, such as refrigerated containers or insulated boxes, to ensure maximum temperature stability during storage or transportation.
6) Cryogenic Containers
Cryogenic containers are specialized containers that are designed to maintain very low temperatures, typically below -150°C. They are a type of packaging solution that is often used for the long-term storage or transportation of biological samples or other temperature-sensitive products that require ultra-cold storage.
