Sealing food packaging is a way to keep your food fresh and safe from external factors. It can also help to extend shelf life and protect the product from moisture, oxygen, and temperature damage. Sealing is usually done with a machine that creates an airtight seal on the package. This seal is usually made of plastic or foil, but other types of seals are also available such as hermetic seals, cross seals, and shrink wraps. Sealing food packaging can be done manually or with an automated machine depending on the size and type of product you’re sealing. With so many options available, it’s important to consider which type of seal is best for your product before deciding.
