摘要

"Seal inviolable attests to the appropriate temperature of chilled and frozen products.Understood by a seal formed by two plastic films, one primary and one secondary school, both cut into geometric shape and arranged in counter.In such a way to form an enclosure that accommodates in its interior, in parallel.Toxic liquid with coloured yellow and blue to solidify at temperatures below the 198 C at the time of freezing or cooling, thus,When the temperature of the products is high, the casing is thawing, promoting mixing of the liquid colorants that are replaced with the green color.In other arrangements, the seal may be formed of the same housing, however,With a central portion solidified in a geometric shape that when thawing occupies the entire space of the casing.The seal may be formed of a sachet of TNT which accommodates in its interior liquid solidified, as well, with the temperature rise.This returns to liquid state and flows through the tissue.
