My 2 cents:
vac sealing- In my state you have to have a special license to vac seal foods. The threat of bacteria is very serious in any package that has had the oxygen taken out. You might be able to get around it if you freeze the food right away, but its not worth the fine you could get or making someone sick.
I buy several differnt types of food trays from
www.hubert.com some are oven/ heat table proof. I don't know how thier price compares to the other ones mentioned in the earlier posts.
I like to serve most of my food on paper boats with plastic sauce cups for beans, slaw ,etc.
When I do a catering job I still use paper plates but I have a hard time finding ones that are strong enough, anyone have any ideas on stronger plates?
I have been looking at dissposable aluminum pans/ trays for carry-out. you can get them with a foil covered cardboard lid that you can easily slap a sticker on.
