I have a cookie-like pastry that I would like to put in a commercial-grade packaging so that it can sold in stores.
How are products such as dates, nuts and cookies packaged so that they have a shelf-life of months or even years? How are small businesses able to package their products? Do they do it themselves or do they send their product to a "packaging company"? What equipment do I need?
My pastry is basically a no-bake almost-cookie-like pasty. It mostly consist of dry ingredients such as almonds, dried pineapples, and nuts but also has a wet ingredient which is either butter or vegan butter. The closest commercial product that I can think of is Larabar but the consistency and taste are different.
