It is unclear who the absolute first person was to invent the plastic bag sealer. Although I cannot provide you with this information, I can tell you who first invented plastic bags. It was a man named Dr. Leo Hendrik Baekeland.
A plastic bag sealer seals plastic bags to an airtight condition and prevent food from going off too quickly. They are usually handheld machines and once sealed the food will stay fresh longer.
"Yes, a plastic bag sealer that uses vacuum packing to remove air and oxygen from plastic bags will extend the shelf life of foods. However, it will not prevent bacteria from eventually growing in liquids."
The first Plastic to be invented was CELLULOID in 1868.

You can reseal a plastic bag without a hermetic sealer by using a simple twist tie or a rubber band. Fold the opening of the bag tightly and secure it with either option to keep it airtight and prevent spillage.
To freeze salmon without a vacuum sealer, you can wrap the salmon tightly in plastic wrap or aluminum foil to remove as much air as possible. Then, place the wrapped salmon in a resealable plastic bag and press out any remaining air before sealing it. Finally, label the bag with the date and store it in the freezer for up to three months.
A food bag sealer works by removing air from the package and sealing it shut. This lack of air inhibits growth of bacteria and other organisms. The sealer first vaccums the air from the bag, and then applies heat to form a seal to preserve the vaccum.

There is typically only one plastic bag inside another plastic bag, unless they are packaged in multiples.
