DryKeep is a desiccant entrained polymer that can be molded into any plastic part. Because of the unique moisture absorbing action the humidity level in any package can be designed to match the need of the product.

 

 DryKeep In Action

 

DryKeep offers many advantages:

  • Maintain ideal internal atmosphere for the entire life of the product
  • Processes in filling like with a standard bottle; no need to heat, loose desiccant insertion or inspection
  • Eliminate potential liability issues from improper use of a loose desiccant
  • Eliminate dusting and leaking issues from canisters and sachets
  • Internal relative humidity can be designed to match the products need
  • Will not release moisture
  • Improve product efficacy

Hi Its good article as it provides alternative to conventional silica gel sachet.BUt i want to know more information about this :-1. Like how much it is more effecient than Cannisters, Sachet.2. Will it provide any gas barrer also? How much misture it can keep out from the package.3. Application part -like what are the areas where we can use .4. supplier is same Multisorb or it is Brand from New comapny ? Thanks and regardsbadal


Badal, to answer your questions 1.  I am not certain what you mean by more efficient. DryKeep allows for a more efficient filling process in the fact that steps are removed, heating, insertion, inspection of the loose desiccant, etc. If you are referring to absorption efficiency it absorbs 3 times more moisture on a weight basis that traditional desiccant systems. In the most cost effective setups it does not provide as dry an environment as silica but it can. Because of this more moderate environment and high absorption capacity it will last for much longer. 2. No gas barrier properties, the amount of moisture it will absorb can be designed into the product the same as traditional desiccants. 3. Right now DryKeep is being used to protect, food, pharmaceutical, chemical and electronic products. In products made via IM, IBM, EBM, and blown and extruded films. 4. TricorBraun is the supplier and though they are new to desiccants that are one of the largest packaging companies in the world today.


Dear JadGood information given. One more question how much it is costlier than the conventional desiccant system.


Badal, the cost of DryKeep is comparable in the North American market to a standard packer and a desiccant canister. As the sizes get larger (greater than 300cc) this correlation breaks down a little, however the cost never gets too far away from this hard cost parody between the two technologies. Even with the small up charge on these larger containers there should be a number of soft cost savings in the filling process. For very large containers there are some other options to protect the contents from moisture, such as scoops for powders that contain DryKeep or DryKeep impregnated film or bag liners. Truly, any packaging option you would want to explore is available. 


Dear JadeThanks for the information. will get back to you shortly. You can contact me on my Email : badalkumar2008@rediffmail.com. Regardsbadal


I understand that this is achieved by mixing the desiccant with colorant and then moulding is done normal ways. So in that case, desiccant would continue to absorb the moisture both from inside the container and from outside. While in traditional ways, the drop in desiccant would absorb the moisture inside the container. Am I correct in my understanding? If yes then I have more questions to ask?


Sandeep your understanding is correct. Let me start by stating that we compensate for the extra absorption from the outside environment by add extra desiccant. Because of the efficiencies of the manufacturing process this is cheaper than managing a multilayer format. We can also run anything that you would like in a multilayer format that offers protection from the outside environment but this leads to a higher cost because of the change in process and added complexity. This is usually the first couple of questions people have, I am certain you will have others so please feel free to ask away.


Thank you Jade, now I understand the concept. Now I have another point, if the outer side would also be absorbing moisture then in principal, the outer surface would be more moist and then it might lead to problems with labels adhesion? Most of the labels in pharma companies have water based adhesives, in that case, will it have any concerns?


This is a common question but the answer is no we have not seen any issues with label adhesion whatsoever. DryKeep does not seek an absolute zero %RH and because of the higher relative humidity we are not drying out glues. If this was a concern packages shipped into environments like Arizona here in the United States (humidities regularly as low as 10%) would cause labels to fall off packages and we do not see that happening. I hope this answers your question.


This seems to be an interesting development. May be very useful for pharma industry for stabilising their moisture senstive products without the use of extermal desiccants. But, we need to focus on two points ; i) Efficacy of desiccant embedded bottle Vs. normal bottle with external desiccants added in bottle. 2) Cost factor ; as in case of most of new developments, the cost of the product comes out be quite high, due to which any new products life cycle may end up to R&D stage only & not feasible for commercialization.


Disha, good places to focus and good questions. i) What data would help you better understand the efficiency; there are numerous ways to measure this. DryKeep works for the life of the product maintaining the same humidity throughout 6 month accelerated testing. DryKeep also repeatedly returns internal humidity as high as 100% back to baseline for over 90 openings of the bottle. 2) This is a very good question and has a very simple answer. In a monolayer HDPE configuration is around cost neutral to a traditional packer and loose desiccant. There are multiple soft cost savings by reducing the complexity of the filling and supply chain operations. It is under detailed review by many large, very cost sensitive operations across a wide variety of markets today.
