Why should the frozen CoolPacs not be placed next to the product load?
The gel within a standard CoolPac changes phase from a solid to a fluid at approximately 0°C, during this change, the CoolPac is able to absorb large amounts of heat energy. If the CoolPac at 0°C or less is in direct contact with the product, then there is a risk that the product may fall below +2°C.
Why do we need to condition the CoolPacs at factory ambient temperature?
To ensure that the CoolPac is completely frozen, the temperature to which it is conditioned must be below its point of phase change. At the point of removal from the freezer, it can become necessary to allow the CoolPac to warm slightly at factory ambient, bringing it closer to its point of phase change, as this will lessen the impact of its introduction into the control temperature package. This conditioning period prevents the product falling below +2°C.
Is there anything special to the CoolPacs that you offer, in contrast to the competition?
Yes. It has to do with the actual composition of our gel. There is a specific formula, combined with our sophisticated production process that increases our CoolPack performance up to 50% higher than the competition. In other words, with less cooling gel we can bring the same results that a competition product may achieve with almost double quantities.
What are the differences in the styles of CoolPacs you offer?
There are two key differences in the styles of CoolPacs we offer. The first difference is the packaging material type. Thus, we have two different kinds of CoolPacks: 1) Those with flexible packaging material (Soft Ice Pack), where we have also two different categories: i) A single Soft Ice Pack, meaning a single ii) A refolded Ice Pack, where we have many single Ice Packs joined together by a special seam. Our innovation against the competition lies on the ability to have Ice Packs of different size and capacity to form a refolded Ice Pack combo. 2) Those with a rigid packaging material, in a form of a plastic flask (Hard Ice Pack). The second difference is about the various sizes, or the various Ice Pack combinations that we may offer.
Can someone ask you to produce on his/her account, a customized CoolPack size, or a special CoolPack combo that would serve
Yes, provided that the desired quantity allows it. You may contact us for further details.
Are your CoolPacks reusable?
Yes, provided that they are not torn, punctured, or opened. They may be used for as many times as you like.
My child has swallowed the contents of one of your CoolPacks. Is it dangerous?
Absolutely not. The contents of our CoolPacks are not considered dangerous for humans and the environment. Nevertheless, we propose to have your child drink a lot of water, or other liquid.
Why do I always seem to have moisture on the CoolPacs?
If using a frozen CoolPac within a control temperature package, it is often noted that at the end of the shipping process there may be some moisture on the CoolPacs. This moisture is simply condensation that has occurred due to the warmer air within the system, coming into contact with the colder surface of the CoolPac and so some of the water vapour contained within the warm air has been released as the air temperature falls.
Do I need to worry about the creation of moisture on the CoolPacs? Is there a chance for this moisture to cause damage to my
No. The isothermal solutions that we offer, they always include internal carton boxes for the products that are able to absorb whatever moisture may be created and prevent a potential damage to the primary product packaging, or any markings on the packaging surface.
How are the temperature profiles used in the qualification created?
Here, at Mediline Isothermal Solutions, we are happy to use customer-specified ambient profiles when qualifying your packaging. Alternatively, we can suggest profiles. We have over 3 years running trials with various companies, where the temperature of the TCP experienced during transit is logged. From this data, we are able to develop profiles to suit your requirements.
Why shouldn't I have my insulated shipping system placed in the fridge?
Our temperature controlled packaging is designed in such a way that can maintain the product temperature at a given range e.g. +2°C up to +8°C and for a given range of ambient or external temperature. If a pack designed to maintain product at +2°C to +8°C for European Summer shipments is placed in a +2°C to +8°C fridge and not the expected +25°C warehouse, the delta T will be considerably reduced. This reduction in the pack's ambient temperature can cause the product to go below the specified minimum temperature. Temperature controlled packaging can be designed to be placed into a fridge or coldstore if required, although this will affect other logistical parameters.
If I put dry ice into a shipper, will it burst as the dry ice sublimes?
Although during sublimation dry ice expands by approximately 800 times from its pelletised format into a gas, our containers do not provide an air-tight seal to their contents and so the gas is free to escape without the issue of explosion. Dry ice should never be loaded into a 6.2 dangerous goods secondary pack. It should be noted however, that adhesive tape should only be used to seal the external box and not to cover any other openings of the complete package. In addition to the above, please note that dry ice should never be used into a secondary packaging that carries dangerous goods.
Why do my temperature recorders always alarm at the start of shipping?
Best practice is to treat your temperature recorder as you treat your product. The excursions that you see will most likely occur whilst being transferred from desk drawer into control temperature package, where they would have stabilised at a comfortable office temperature, rather than a product one. Storing the temperature recorder within a +5°C environment prior to use and adding a 30 minute start-up delay would remove the high temperature excursions.
Why do my temperature recorders always alarm at the end of shipping?
An alarm at the end of shipping could simply be that the temperature monitor was removed from the system, but was not immediately stopped and so began measuring external temperature prior to download.
Do you take your used packaging back?
Yes. Mediline Isothermal Solutions has the facilities to offer a disposal program. If you would like more information regarding this, please contact us.
How do I safely dispose of any packaging you have supplied after use?
Our products are designed in such a way that the separation of its various parts is a very quick, easy and simple process. For further management, please consult your relevant local legislation and practices.
Must I only order a validated Isothermal kit among your existing product range, or do I have the option to order an Isothermal
No it is not necessary. Our fully validated isothermal kits that we propose, they have derived from extensive validation test procedures that were performed on behalf of certain clients. There is a chance that one of those kits might suit your requirements, which in this case will save you the time consuming validation process. Otherwise, we must perform a thorough research, aiming for a new isothermal kit, customized to your specific requirements. Should you require just a new design, without any validation done for it, we can of course provide you with only that.
How long does a validation process last?
A validation process depends on many factors. The duration depends on the complexity and variety of factors that we may be asked to include. From our experience, a validation process may not last less than 2-3 weeks.
Do I need to use an outer carton for my temperature controlled packaging?
Yes. The outer and inner boxes support the assembled insulation part of our packaging and also protect it from potential damage and mistreatment. The benefits that you may have due to reusability, as well as the reduced storage and transportation cost while being disassembled, is significantly superior than the small extra cost that is added due to the presence of those boxes.
Where is the best location for a temperature monitor in my shipment?
Absolutely inside the very product itself. A temperature controlled packaging even if it is designed to maintain internal temperature within a certain range, these values, if measured by temperature monitors, may be sometimes outside this range. This occurs due this being the air temperature and not the product one.
Why are some of your validation tests successful, while temperature was at some points below the accept limit?
The temperature monitoring devices used at Mediline Isothermal Solutions monitor the air around the product. As it is known, the air surrounding the product is more susceptible to temperature change, due to its lower thermal mass, its changes look more dramatic when compared to actual product reading. This does not happen to the actual product, which is not affected by those fluctuations, unless is exposed to such incident for a great amount of time.
Do you suggest any label text to alert the receiving site that the shipment is of temperature sensitive product?
This is a long-standing point of debate and in our experience, no one particular phrasing is any better than the other. In our packaging we propose the following: “ATTENTION! This isothermal packaging contains products to be preserved between +2°C to +8°C. DO NOT FREEZE” We also propose an additional marking to the outer box: “Upon receipt remove product and place in a +2°C to +8°C store.”
Why should I use temperature controlled packaging for shipping 'Temperate' product?
What is Temperate? Our research into this leads us to believe that it is most commonly +15°C to +25°C or +2°C to +25°C. Much debate occurs over this issue and one thing that is certain is that your product will need to be kept out of some temperature environments. What will happen if a simple packaging meets extreme temperature conditions (polar frost, burning heat, or extensive sun exposure during mild conditions)? If any simple package meets such conditions, then the use of a temperature controlled packaging becomes a necessity.
Is your temperature controlled packaging reusable?
Yes. Provided that each client has developed a method to recollect the used packaging and the latter is intact. However, even if some parts of the packaging are damaged, we are able to provide our client with spare parts and not a complete new package.
