Morning Adie,
Following up from our meeting yesterday.
After receiving sample pens from yourselves I had some of our staff put the pens through their paces, The Super XP Cryo pen was issued to one of our very cold Deli department. Mark certainly went that extra mile to test your pen, He did the following things over a six day period:
· Dropped the pen on several occasions
· Dropped the pen into oil (either Rapeseed or Olive)
· Dropped the pen in to water
· Allowed it to write on paper with powder residue on it such as flour and spices
All of this happened in an area which is constantly below 4°C, I taken the Cryo XP pen off Mark and passed it on to one of our vessel minders to trial it in a warm-hot working area (Cooking), Just to make it clear Mark was not at all happy about me taking the pen due to how good he found it.
I will update you next week to conclude our trials.

Subject: X-ray detectable plastic
I used butter 45mm deep. I cut up one of your pens and flattened out a side wall section, it measures 1mm in the path of the X-ray beam. I tested the plastic on top of the butter (additional) and then again embedded in the butter. The results were very good.
The butter itself has an average pixel value of 75 points. 1mm plastic additional gave a value of 43 points – so contrast is 32 points (very good) and 1mm plastic embedded gave a value of 52, a contrast of 23 points (still very good).
To give you an idea of what this means – 1.0mm of this plastic embedded is equivalent to 2.5mm Soda Lime Glass embedded.

Subject: X-ray & Metal detection tests
Hi Sean
Just a quick update I did some more testing this week on the x-rayable & metal detectable products. I managed to test the x-rayable bandaid in the glass line x-ray & found that it rejected it 100% of the time. The three metallic strips within the bandaid were very clear on the machine, although the remainder of the bandaid was invisible on the image. This is obviously because the plastic is so thin & light weight. The x-ray was playing
up, so I couldn't spend any more time on it (hopefully more testing next week).
I then took the various samples -pen, bandaid, bag tag, cable tie, hairnet & glove to one of our metal detectors & ran them all through the machine. (Safeline Profile metal detector).
The results were stunning. All samples were 100% detected & rejected- even the tiny little bandaid. The indicator on the screen of the detector went from green to full red bars (off the scale) showing me that it was very easily seen by the machine.
I'll keep in touch with further developments

Subject: X ray images
Hi Sean
Here are some of the images of plastic that I tested in our glass line x-ray. The results were very exciting, and quite clear images from the machine. We were able to reliably detect down to a 3mm piece. I have sent this & the presentation you sent through on to the head of quality.
These images were taken at 550 jars per minute on a Quad beam x-ray. I firstly tried the plastic in water, then on the smallest piece I actually had it in the product (Seafood sauce) to really test out the plastic's limits. Jars are 250 gram of 1.5mm wall thickness.

Hi Sean
I carried out some very brief tests of the new improved x-rayable plastic, via a chopped up pen and plastic scraper
The machine has been tied up with a technician so I haven't been able to get images but the results were fantastic for the blue plastic. The images were much stronger than the initial pen that I tested, and even the thin plastic of the scraper (2mm wide) was seen every time which was very encouraging.
A 26mm x 10mm x 2mm (scraper edge) 100% pass
B 8mm x 8mm x 10mm (end button) 100% pass
C 8mm x 8mm x 28mm (hollow tube – hence less dense) 100% pass
D 13mm x 6mm x 3mm (small clip) 100% pass
