Construction
An insulated shipping container might be constructed of:
- a vacuum flask, similar to a "thermos" bottle
- fabricated thermal blankets or liners
- molded expanded polystyrene foam (EPS, styrofoam, etc.), similar to a cooler
- other molded foams such as polyurethane, polyethylene, etc.
- sheets of foamed plastics
- reflective materials: (metallised film, etc.)
- bubble wrap or other gas filled panels
- other packaging materials and structures
Some are designed for single use while others are returnable for reuse. Some empty containers are sent to the shipper disassembled or “knocked down”, assembled and used, then knocked down again for easier return shipment.

Famous quotes containing the word construction:
“There is, I think, no point in the philosophy of progressive education which is sounder than its emphasis upon the importance of the participation of the learner in the formation of the purposes which direct his activities in the learning process, just as there is no defect in traditional education greater than its failure to secure the active cooperation of the pupil in construction of the purposes involved in his studying.”
—John Dewey (1859–1952)
“There’s no art
To find the mind’s construction in the face.”
—William Shakespeare (1564–1616)
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
