Do vacuum seal bags actually reduce weight?
No, vacuum seal bags do not reduce the actual weight of the contents inside. Instead, they compress the contents to reduce their volume, making it easier to store or transport items. The weight of the items remains unchanged regardless of how they are packed. This means that while you may feel like you are handling lighter baggage due to the improved packing efficiency, the overall weight is the same as it was prior to sealing.
However, what vacuum sealing can do is help manage how weight is distributed. By packing items tightly and efficiently, you can create more space and possibly carry more items without exceeding weight limits. This organizational approach is especially beneficial for travelers who want to maximize suitcase capacity without adding excess weight.
How do vacuum seal bags work?
Vacuum seal bags work by removing air from the bag and creating a tight seal around the contents inside. The process typically involves placing items inside a specially designed bag, using a vacuum sealer to extract the air, and then sealing the bag to prevent any air from entering again. This method significantly reduces the amount of space the items take up, minimizing the risk of damage during transit and helping to protect against moisture and pests.
The technology behind vacuum sealing relies on the principles of atmospheric pressure. With the air removed, there is less friction and fewer obstructions that can lead to spoilage or degradation of the items inside the bag.
