exelent for shipping live insects,reptiles,fish,flowers,etc
provides an average warmer surface temperature of 100 degrees fahrenheit.
40 HOUR HEAT PACKS Will ACTIVATE IN APPROX. 40-50 MINUTES.
THE SURFACE TEMPERATURE IS APPROX. 110 DEGREES AT ITS PEAK.
THE 40 HOUR HEAT PACKS WILL RELEASE A STEADY TEMPERATURE AND PEAK OUT BETWEEN 17 TO 19 HOURS.
THE 60 AND 72 HOUR HEAT PACKS ARE SIMILAR TO THE 40 HOUR EXCEPT THEY LAST MUCH LONGER AND REACH THEIR PEAK TEMPERATURE AT APPROX. 25 TO 28 HOURS.
THESE HEAT PACKS ARE EXCELLENT FOR EXPORT SHIPMENTS OR SHIPPING VIA USPS PRIORITY MAIL.
The idea of using the heat pack during the shipment of live insects is not to achieve the optimal temperature inside the box but to keep the temperature from falling too low that it may cause the insects to be very stress or die.
There are 2 sides to the heat pack. The side with the red strips, which have many tiny perforations, must always be exposed to air. Do not lay the red strips side flat on any flat surface or tape it down in such a fashion that it may obstruct the air flow into the perforated holes.
If you use a cubic foot insulated box for example, the first heat pack will raise approx. 12-16 degrees and each additional heat pack will raise approx.10 degrees more. the temperature range of 60 to 75 degrees is very save for most insects during shipment.
If the temperature in the shipping box falls below 32 degrees (freezing point), the heat pack may cease to work because water, which is one of the main ingredients of the heat pack, may become frozen.
If the tempature is 40 degrees F. or colder you will need to add heat packs to your live order. You need to do this for the benifit of your insects. We can not offer a live quarantee if you choose not to add a heat pack to your live order..
In extreme cold, it is safer to have the box held at the local hub or post office then call the consignee for pick up.
