A heat sealer can be a good choice for any production facility as it can work to close a variety of packaging materials, and most sealers offer a number of choices for how a bag or other package is sealed. They may also have other features you may need before shipping out your product or putting it away for storage. If you're considering a heat sealer for your facility, note a few important factors to consider. This will ensure you choose the right sealer with the best features available.
1. Speed of sealing
For high-volume facilities, you need a fast sealer than can continuously move product through a line. This often means a continuous band sealer, which is typically connected to a conveyor or other part of your production line. The continuous band sealer may offer a continual line of heat sealing with just short interruptions between each piece, so you can constantly feed packages through the line without stopping to lower an arm or otherwise feed the bags and materials into the sealer.
Some heat sealers work with a round or flat sealer and some work with a wire element. The wire element is usually used when you need to cut the bag or other material after it's sealed. If you have product that will need trimming after sealing then choose the wire element; this often eliminates the need to feed your bags or materials through a second line to have excess plastic or other materials trimmed once the package is sealed.
Some sealers come with a vacuum attachment, and this can be needed for food products and to help prevent rust, corrosion, or other damage to materials that should not be exposed to air during shipment. Having the vacuum feature attached to a heat sealer means that the packaging will get sealed immediately after air is vacuumed out, which in turn offers the most protection for your items.
4. Foot sealers
A foot sealer sits on a type of stand or pedestal and a bag or other package is fed into the sealer by an operator. Usually an arm is then lowered on the bag or packaging and the heat is applied. This can be the best choice for very bulky items that may easily spill along a conveyor line or for delicate items that may require a human interface to ensure nothing is damaged while the package is being sealed.
