This is the machine that makes Gel Paks. Alongside is an automatic impulse sealer that seals the packs with a 5cm seal.
A Gel Pak is a frozen plastic bag containing water and a polymer that forms a gel. When frozen it is a dry ice as opposed to wet ice that turns to water when it thaws. Once the polymer has absorbed the water, it cannot release it except by evaporation of the water content. This makes it safe to use in applications that require chilling or low temperature control where melting water from ice could become a hazard or spoil goods. The polymer is USFDA & EU approved. Gel packs maintain their temperature two to three times longer than wet ice. A common example for use is in air freight consignments that are required to be kept chilled i.e. seafood, live lobster, crab etc. Airlines require its’ use to avoid possible leaks of melt water into aeroplane interiors causing corrosion and or damage. (It has happened in the past at $1 million cost). It is used by drug companies to maintain temperature in drug consignments, ditto for pathology specimens, in fact, anywhere that a dry chill is required. A further advantage is that the user can usefully and profitably employ staff who are currently under utilised. Your savings are inward freight on water content (99.9%), packaging, overhead and profit the manufacturing supplier needs to make. This is a simple, fool proof manufacturing unit at lowest cost per unit. This entire unit is made of stainless steel and plastic. Corrosion free for life. |
