Once you've selected the proper size and capacity of can for your product, the next step is to ensure that your can will be properly sealed and ready for shipping. Heavy-duty can sealers can get this job done, whether you do it by hand or use an electric sealer. Ideal for use in industrial settings, hardware stores, or even for home canning, metal can sealers interlock the lid of the can with the sides, creating an air-tight seal in a process called double-seaming. Some sealers can be used with multiple can sizes, so make sure that you choose the correct size before you order can sealers wholesale. Once your can is safely and properly sealed, it is ready to be labeled, and then shipped out for sale.
Hand-operated can sealers are designed for continuous use, and operate by using a hand crank or flywheel to press the lid down on the can. These open top can sealers can be used on several sized cans, and are made for heavy-duty applications. A rotating base supports the can during sealing, while two sets of rollers lock the lid to the can, and then tighten and smooth the seam. Lid press sealers, used for sealing paint cans, are often used in hardware and paint stores. These sealers attach to a bench or desk, and can be used to seal a variety of paint can sizes.
A less manual option for sealing your cans is an electric can sealer. These sealers can also be used on open top cans, and work much like their manual counterparts. The advantage to an electric model is that they can often handle a greater volume consistently, as they are not dependent on an operator to keep turning a crank. These machines also handle different sizes of cans, and may be portable, making them a good choice for small production or home canning.
