Can sealers are used for home and industry canning purposes to seal lids on cans airtight. The sealer interlocks the lid with the top edges of the can during a process called double-seaming. Some can sealing equipment has an adjustable sealer, so you can use it with several sizes of cans. Open top can sealers are useful for home canning, hardware or retail stores that mix paint, and food processing plants. Find sealers and other canning and bottling accessories at Berlin Packaging.
Anatomy of Can Sealers
Electric and manual sealers both have rotating bases to support cans during sealing, seaming chucks to hold and support the lid, and two sets of rollers. The first set of rollers locks the lid to the can, then the second set tightens the seal and smooths the seam. Electric sealers are supplied in standard sizes, and in portable versions for easy carrying and storage. Manual can sealers are supplied in open-top can and lid press sealing varieties. Lid press sealers, also known as paint can sealers, are commonly used to close paint cans.
Open-Top Can Sealers For Airtight Seals
Using open-top can sealers provides an airtight sealing option that protects contents from air and foreign materials. Both manual and electric can sealers are made for frequent, heavy-duty use, and support several can types and sizes. Options like portable electric can sealers are also fast, efficient, and practical for heavy use jobs.
Practical And Efficient
Hermetically sealed cans prevent bacteria, debris, and other contaminants from getting into your product during filling, shipping, shelving, and storage. Open-top can sealers create a hermetic seal for foods, solvents, paint, and a variety of other products, potentially extending shelf life. To get the best seal, and to help products keep longer, leave at least a quarter of an inch of empty space at the top of the can you're sealing.
