This is a long shot, but does anyone here work for or have experience with a packaging supplier?
I am in the middle of creating a frozen food product and I am trying to figure out a sleek packaging design that will allow the contents to be easily removed without the chance of the product sticking to the inside.
I can obviously go with a poly bag like a Popsicle is contained in, but that is not modern and sleek enough. It is essentially a cylindrical piece of ice measuring 6" long and 2" in diameter. I have been in contact with silicone and glass bottling manufacturers through Alibaba, but I feel the cost may be too great. Plus, if I go with a glass bottle I will definitely need some kind of coating so the product does not freeze to the glass.
I was thinking some kind of thick (maybe 3mil) shrink wrap/vacuum seal poly bag may work but I'm not sure how that process works yet. Can anyone chime in?
uhh, holding the package in ones hand for a minute should be sufficient to slightly melt a layer between any packaging and your frozen food. some people prefer to run under water from a tap rather than get a cold hand.
you dont need any special coating.
Right now I am using 250ml and 500ml graduated cylinders as molds and to remove the product I run them through a hot water bath. They don't come as easily as you think. I bought a piece of 304 steel pipe I'm going through the try and use as a mold to see if that works better.
On the consumer end I don't want the costumer to have to run it under hot water.
well I leave the ice cream out of the fridge for like two minutes before serving it so its not so rock hard. i dont think its super inconvenient.
I think your problem is that you're using a rigid packaging. because the packaging isnt flexible, it cant deform with the vacuum created by trying to extract the tasty treat. take a look at callipo ice "cream" its just paper coated in some kind of plastic to stop the water from leaking through.

although any kind of food safe plastic should be fine. hell you could use poly tube and just seal it at both ends with a plastic melting sealing thing.
Put a tiny packet of that exothermic stuff used in hotpacks at the very bottom of the tube. Consumer opens the top of the tube, smacks the bottom of the tube on the counter to mix the reactants, and boom - food heats up marginally, releases from the plastic, and rockets out of the tube due to gas pressure.
I'd like 10% of your profits, please.
