Abstract

A double bag vacuum insulation panel for use in a temperature assured shipper made in a steam chest molding machine is provided. The double bag VIP comprises a porous core, a heat sealable inner envelope and an outer bag. The inner envelope is made from a substantially gas impermeable first material having a first thickness and defines an interior having a pressure of less than or equal to about 30 millibar. The outer bag is made from a substantially gas impermeable second material having a second thickness. The outer bag encapsulates the inner envelope. The double bag vacuum insulation panel has an R value of at least about 28 hr-ft-° F./BTU-in and the R value drops less than about 10% after being exposed to a temperature of up to 95 degrees C. for up to 7 seconds.
