Is it safe to use Marker Pen on foil food wrapping?
We are producing a chilled meals to the market, like pizza or chicken fajita , but these type of meals should be reheated inside the oven , for that we wrap the meals by Aluminum Foil , and we write the name of the meal by using normal typ of marker , because the label can not be stable during reheating in the oven , but marker ok, the problem is we dont know if the marker is safe to use in the food establishments or there are some approved markers only can be used? please advise .

Here is a link to the type we use, but if you search on t'internet for metal detectable marker pens, there are several options:

We use metal detector marker pens, so I they were to get into the product the metal detector/x ray machines pick it up, they also work in ferrous metal detectors.

Dear beantester:
Thanks for the interested link , but I am not sure , can I write on the aliminium foil or not? Is it readable ?

From what you say the marker pen is used on the outside of the foil and the food is fully wrapped; in that case it is impossible for the ink or chemicals from the marker pen to migrate through the foil to the food as foil provides a 100% barrier. Have you tested it? At what temperature? Does it stay on / burn off? Rub off on hands?
We tested on the chilled -cooked food ,by writting on the foil pre reheating , its ok, but post reheating can not be estable while exposure to the high temperature , so some words removed and thename of the food becomes unclear and unreadable , what I think , is there a special lables or stickers can be heat resistance ? maybe can be better than writing direct on the foil .

What temperature is involved ? > 100degC ??
There are surely (commercial) products available for yr requirement. I have just microwaved a plastic food meal tray to (internal) liquid boiling point. Has a paper/plastic coated outer label / ink-jet looking production date.

Foil generally is not a good choice especially if you heat the food product in contact with the foil, due to a possible reaction between the food and the plain aluminum.
Moreover normally the foil thickness being in the range of 14-15 microns is not free of pores (see attached article for instance for holes allowed in Aluminum foils), and penetration of ink and solvents is certainly a possibility that you should be taken into account.
There are certainly better solutions, however possibly more expensive.

I think the aluminium foil is approved by the Authorities, and still no studies proved that the foil can react with the food or can be a toxin. it is using commercially in many companies , because no alternative wrapping items can be used and keep the food in a suitable conditions such as the aluminium foil .

??still no studies proved
thatif the foil can react with the food or can be a toxin.
Really ? Are you referring to yr local Al foil / authorities or in general ? If the latter, I doubt you are correct after all these years of usage but it's not my area.
Any more opinions ?

In general , see this link , about the aluminium in food .

Thks for the interesting link.
It says a lot and the corrosive aspects unquestionably exist but seems to end up by concluding nothing. Agree ?
Meanwhile the Tv dinner business in Al trays rolls on.
Let's pray it won't be like asbestos.

Good find.
There appears to be some confusion over the precise definition of “R1”.
Eg here - http://www.nsf.org/b...m=NonFoodComReg
it is - Coatings for use on direct food contact surfaces
(my underlines)
whereas in the cumulated product status book it is - Coatings for use on incidental food contact surfaces

The whole subject of categorizing the safety of packaging coatings is obviously a mine field –
