Can you use aluminum can for retortable products?

The simple answer is yes - Aluminium is in regular use for retort packs. You can find retorted packs of petfood (the small square foil-lidded trays) which are all aluminum and you'll also fins some aluminum cans of pate, fish etc all of which are retorted.. The tendency to use steel cans has been, I think, more to do with cost than suitability so cans would be equally good. Plastic materials are also used in retort applications, paticularly in pouches. Once again, you'll find petfood, soups and sauces in this style but they're also the pack of choice for military rations as they're flexible, compact and easy to reheat.


Why do tin cans get crushed if cooled after heated and closing is mouth?

Would soda cans explode when brought on to mountains?

Soda cans can explode at high altitudes due to the change in air pressure. As altitude increases, the air pressure decreases, causing the pressure inside the can to be greater than the pressure outside. This pressure difference can lead to the can bursting or exploding.


Is propane gas liquid or gas?

Propane is a gas a room temperature if it is not compressed. However, if it put in a canister under high enough pressure, it will be a liquid even at room temperature. Propane is a liquid below -44 degrees F or if its compressed. Grill bottles are only fillid 80% full with liquid. so you can use the propane gas on the top of the bottle.
