Tyvek

It should be ehat sealable. Ask these guys.

DuPont™ Tyvek® Home Page

ehat? must be a process i'm unfamiliar with.

EHAT™ is a new proprietary sealing system being developed by LynDoor™ Industries for sealing Tyvek^® and Gargonite^® fabrics. It uses a revolutionary cold fusion process that does not disturb the fabric's unique fiber orientation.

It is also unique because it can easily join these two dissimilar materials together for the first time since they were developed, Tyvek^® by DuPont™, and Cargonite^® by the Exotic Materials Division of LynDoor™Industries.

Since they are made of mutually incompatible materials they have never been used together before. So now the optical clarity of Cargonite^® can be used to allow see-through packaging, while utilizing the less expensive Tyvek for the rest of the package.

Disregard my partner's humorous reference to some of our "technical discussions" during development in post #3.

Oh, no!!!!!!

I responded to an anonymous poster.

No... no... it was me... I'm actually not sure why it posted anon.

Just had to get some smarta$$ comments off my chest before heading home to the misses... I find that if I get it all out of my system it makes for a much more pleasant evening.

Huh?

an whats with this EHAT shirt?

You feedin me a line, tryna pulla stroke, givin me some Grief here Bud?

You better watch your back Im tellin ya. Shame if anythin happen to nice guys like you an your little Buddy.

That one however... was not me.

We may be accepting a limited number of discriminating investors for this venture.

Someone of your obvious technical sophistication might be considered as a limited partner.

Have one of your people call one of my people.

Wrong market--you need undiscriminating investors. That's the real bright side--there are so many. Success may be in your future....

_{Shhhhhhhh I'm working the mark here.}

Darn it, Lyn, quit doing that LynDoor thing! It sounded so good (and I'm so gullible) I had a check halfway made out to send in before I caught on.

I think Lny is dyslexic and you should use heat not ehat

BTW I am working on a cold fusion process. It provides heat but I would not recommend using it to seal your products.

The typical 3 points of disbelief are and addressed as follows.

1. Over coming the coulomb barrier
1. LENR is a weak interaction and only involves the accumulation of low energy neutrons.
2. No fast neutrons.
1. This reaction is due to the accumulation of cold neutrons and Beta decay. Similar to the S process in solar nuclear synthesis which is responsible for the valley of stability in the Chart of Nuclides.
3. No Gamma rays.
1. The 4H system is formed well below 1eV and does not change parity or spill with the Beta decay event. With no spin parity change, electric dipole radiation of gamma rays is forbidden and the energy is transferred to the lattice as phonons. (Julian Schwinger)

Based on the Brillouin Energy Corp.(BEC) hypothesis and supporting experiments at Brillouin Energy, LENR is driven by a weak interaction. Any material with a unit cell or molecule able to include hydrogen nuclei and obtain or exceed a Molecular Hamiltonian of 782KeV due to the superposition of phonons (dT < fSec) has the potential to run a Controlled Electron Capture Reaction (CECR) process, providing the system has conduction or valence band electrons available for capture. Peter Hagelstein showed that this is possible starting on page 24 of his article in RLE Progress Report 145. The electron capture event provides a natural reduction in energy of the system instantly removing 782KeV of energy from the unit cell nanoparticle or molecule. That energy represents the removal of a proton from the bounding Coulombic box, an electron, and conversion of energy to mass.

A detailed paper / Hypothesis is available at the links below. It stays within the current (2011) standard model of physics. This reaction involves several steps that require some knowledge in several different disciplines. The first link provides the background necessary. I strongly recommend LISTENing to the power point at
http://www.brilloui nenergy.com/ BE25Tec.PPS at least once before reading the full hypothesis at
http://www.brillouinenergy.com/BrillouinEnergyHypo thesis.pdf

BEC is not the first mover in this field but our technology will grab the market as our technology comes on line. people should google Rossi Swedish skeptic society for information on the first mover in this field

In Rossi's reactor the neutrons accumulate in the Ni lattice / nanoparticles, The xms spectra I saw did show some accumulation of some Zn in the system as well. Because Cu is less reactive than the Ni due to the electron shell structure Cu tends to be the main end result of Ni transmutation through the accumulation of neutrons (Google S process). I strongly suspect and the hypothesis predicts that if someone were to use a good Helium detector they would also find 4He coming out of a Rossi system.

Wow,

And I thought I took us off topic. I believe this belongs in the commercial section.

Anyway, I guess if it pays the bills why not tinker around with it.

I'm still hung up on some of the conversion rational and the lack of consistency, but maybe it can be made to function as you hope, if that's your cup of tea.

After all, Al Gore didn't invent the internet overnight.

Gosh, I so missed you guys and gals!! Nothing like this over in the 'Sand Box'!! I must have been gone longer than I thought (time dilation, methinks), but, when I left Tyvek was a Vapor Barrier used in construction and actually does 'breathe'.

More things change on me??

Please advise and warmest regrds,

Very common packaging method. You don't give your location, but you will need to contact suppliers who will cut and print your Tyvek covers. You need heat sealers of appropriate type and size as well. Often used with ETO sterilization.

Are you, or do you have, a packaging engineer?

Medical Packaging is a non-trivial adventure. Start with www.devicelink.com.

Are you sure that PVC is a permitted material for long term contact with implants? There is also the issue of residual epichlorhydrin in EO sterilization of PVC. Tyvek can be heat sealed to such packaging.

PC or PET thermoforms may be better alternatives.

Yes, you need a heat sealer of sorts.

But then you need to go through the mission of testing and validating your machine and seal (Also - all of this must be done in a clean room).

Thus if you're a small start-up try and see if you can't outsource the whole cleaning and packaging process - it will reduce your liability and make life easier for yourself.

If you're bigger consult your QA or notified body on what the regulations require with regards to packaging.

Also not sure about the whole PVC business...

Cheers!

I am with Lyn #4, as a prime example of superb vercomplicator. The process is exemplary, and I would like to invest the content of the kitty in the upcoming startup for a very silent partnership.

On the other hand, my Simple Hungarian Engineer's mind wonders about the original question. PVC for packaging such a critically clean component? I would not think so. PVC is an inherently brittle material, rendered useful by the addition of plasticisers. They outgass. See the dashboard of an 10 years old car for results. Outgassing into a cleanroom rated device? It cannot be permissible.

But, as it appears, that sterilization does not involve excessive heat, what is amiss using standard packaging, like polyethylene, for example?
