    Heat Pack Testing Trial Number 2.

    The heat pack is now wrapped in a good sheet of newspaper.



    As soon as the box cools, I will repack it this way, and try again.

    Re: Heat Pack Testing Trial Number 2.

    Hi,

    If the point is to simulate what happens during real snake shipping I would suggest unblocking the airholes as well.

    In fact I'd buy a smaller min max thermometer, put it inside completely in the snake bag and ship it to yourself overnight or to someone who can be prepared to open it in a relatively similar temp environment to the one in which you packed it.

    Do the different duration heatpads also have a different warm up and cool down time?

    So that a 24 or 48 hr will never get as hot as a 60?

    No, my understanding is that everything from 40 hour on up will get up to 110. They just peak at different times.

    Here's the starting temps.

    Now, at 9:30 PM, the temperatures look fine.




    But at 10:30, I see that the internal temp of the box has dropped some, along with the outside temp, which is worrisome.



    I'm going to give this one another hour. If it's still in the 80s, I'm putting it outside. If it's dropped further, I'm going to call it a failure, and try looser wrapping.

    I AM simulating what happens to a box during shipping. It has to hold a reasonable temperature at normal room temperatures, and it also has to hold a reasonable temperature when it's freezing cold.
    Holes in the box--some people do, some don't.

    Box needs ventilation to keep heat packs working 100%.

    I just had a snake shipped here in the mid 30s and arrived warm.

    Air holes are a MUST if you want heat to work properly

    Don't worry, if this test fails, air holes are the next step. I have not taped across all the sides of the box, just a strip down the center to close it. I'm trying to test the most common configurations people use when shipping with heat packs, and no air holes is one very commonly used.

    Worked perfectly inside, fell to 50 F outside after an hour at 33 F. So, failed.

    Will retry tomorrow with looser wrapping and air holes.

    Also dont wrap the heatpack. The paper is obstructing even air flow that the box does has, which will comprise the oxidization inside the heat pack.

    Re: Heat Pack Testing Trial Number 2.

    most heat packs are air activated. it needs air in order to produce heat.
    what i do with my packaging is i put more or larger holes when the weather is colder. i also place the heat pack on the side of the box centered on an air hole. usually this hole is the largest hole appx. a qtr inch diameter. i have no choice in shipping in cold weather as i ship from buffalo area.
    last week i sent some snakes out and it was quite cold. they arrived safe and sound.
    if you would like i could try and contact the buyer to find out if he remembers the heat pack still being warm or cold.
    i use the 18 hour hot hands from walmart.
