Pail closing machines are usually the last in line during the main packaging process, not counting the labelers. Some are automatic and are part of a long line of assembly machines, from the fillers to the lidders and cappers on through to the labeling machines, while others are manual in nature and can be used on a simple tabletop workspace.

If pail closing machines are poorly designed and fail to properly seal lids and caps onto the pails, a lot of problems would arise. During transportation, vibrations from the truck or boat could cause a lid to pop off, spilling food all over the other containers or causing toxic leaks of flammable chemicals. Or, even worse, this could happen while a customer was carrying the pail herself.

Because pails come in all shapes and sizes, it is essential to purchase a closing machine capable of crimping or snapping on a variety of different lids and caps. The more versatile the closing machine, the more economic it will be to adjust to changing consumer, market and packaging demands. Thus, if a specific size of pail is selling out faster than other sizes, a factory manager will know to set his machine to that size for a period of time to make up for sold-out products.

Types of Pail Closing Machines

For friction top plastic and metal pails, the best types of closing machines are electrically-operated and explosion-proof pressure machines that either utilize a rolling or top-loading mechanism to snap pail lids onto place. Crimpers utilize a side and center-ways motion to forcefully close the sides of a lid onto the opening of the pail, and are great for pails with minimal liquid pressure. Some pail closing machines are automatic and require no operator while others are completely manual or pneumatically powered and are great for small business operation.
