Thermal packaging maintains the desired temperature for an extended period. It entails using materials that can be activated to heat up or cool down where ambient temperatures differ from the delivery conditions. Thermal packaging solutions are designed to maintain a constant temperature. This includes high or low temperatures, moisture, ambient air pressure changes, and energy fluctuations. These solutions protect products from outside influences caused by motion or vibrations. The common types of thermal packaging solutions are as follows.
Thermal Pouches
Thermal pouches are commonly used thermal packaging solutions. They include adhesive thermal pouches, cold seal thermal pouches, easy-open sealing strip thermal pouches, etc. They produce a thermal shield to help maintain food or beverage at a specific temperature. Thermal bags use the chemical adhesive epoxy to stick onto a carton. This thermal packaging solution effectively maintains temperature for up to six hours.
Thermal Bags
Some examples of thermal bags are t-guard bags, thermolock bags, etc. Thermal loads use a reflective metallic coating to reflect heat produced by the product. These bags have an opening at one end. The space allows heat from the product to escape. Heat is reflected onto the product by a metalized inner layer of the bag when ambient temperatures are lower than desired. Thermal bags are best used for cold chain shipments. They can maintain temperature for up to three days.
Thermal Rolls
Thermal roll products are used to maintain product temperature during transportation. Thermal rolls examples include a cold seal roll wrap, easy-open sealing strip roll wrap, etc. They use highly adhesive epoxy roll film to seal cartons. It can also be used in several other cold storage and display cabinets. The product ages or loses effectiveness once the protective coating is removed from the packaging material and exposed to air. Rolls of thermal packaging can maintain the desired temperature for up to three weeks.
Thermal Bags with Fill Ports
Such bags include the easy-open sealing strip wrap bags. Thermal bags can be filled with water. If needed, this can be done to maintain a precise temperature while shipping or storing perishable items. Some perishable items are such as seafood or vegetables at home. These bags can also be filled with dry ice. This helps maintain an indefinite temperature such as meat or seafood on display at a supermarket. Thermal bags with fill ports are heavier, more expensive, and should be explicitly used for cold chain shipments.
Thermal Trays
Thermal packaging solutions are often used for extended transportation periods. Thermal trays include T-Packs, Transformable, etc. They use epoxy adhesive and polyester webbing or plastic trays. These products are used to pack frozen food in a heat-sealed carton. This product is ideal for storing meat, fish, vegetables, and perishable items that require a higher temperature to be held successfully.
Sometimes, you may want to transport a product or package. In some instances, you need to do so quickly, safely, and from one point in the world to another. Thermal solutions can help with this. They not only ensure that your goods are delivered in good condition. They keep different products at specific temperatures for various lengths of time or materials up to large thermal containers capable of storing many items. The packaging also remains suitable for use throughout transport.
