US Patent Application US20150375915A1
Thermostatic packaging materials
Angele Sjong co-inventor
Details of the Patent
Technologies are generally provided for thermostatic packaging materials for packing temperature sensitive products such as foods, beverages, biological materials, pharmaceuticals, vaccines, and live organisms. The thermostatic packaging materials may be formed from a number of substrates in which thermo-responsive capsules may be suspended. The substrates may be composed from a gelatin film substrate in some examples. The thermo-responsive capsules may encapsulate a cooling agent for reducing a surrounding environmental temperature. The thermo-responsive capsules may be composed from a polymer such as poly N-isopropylacrylamide (PNIPAAm), which may be configured to release the encapsulated cooling agents when the surrounding environmental temperature reaches a threshold temperature. The substrates including the suspended thermo-responsive capsules encapsulating a cooling agent may be layered together to form a laminate having many cooling layers to provide a staged release mechanism to continuously provide a cooling effect for packaged materials.
