Can seaming has been around for years ever since the need for a more robust food packaging solution was due. It has undergone some massive transformations over the years to become the most widely used option by manufacturers and packaging suppliers in the world. But how safe are they? Are there any guarantees that consumers get as far as the safety of the canned products is concerned?
We are going to look at can seaming inspection, all the counter checks that packagers have to conduct to ensure that what they relate to the consumers is sealed and safe for use. If you have been curious to know how quality assurance is done in this level of packaging, then stick around to the end.
There are a number of can seaming defects that can come up from the process and if something is not done, they could lead to some serious issues for the safety of the contents inside. The following are some of the can seam defects.
A can seam has to be inspected to ensure that it works as it should. Having looked at some of the defects, it is easy to see why this is necessary. There are certain parameters that are used in the inspection process, and they include the following.
Seam Thickness: There are specific ranges that a can seam must have for it to be cleared for use. The thicker the can, the more the pressure it can withstand. The thickness is usually measured using a micrometer.
Seam Height: The seam height is another great indicator of the overall pressure that the container is able to withstand during the seaming operation. The height of the seam can also be measured using the micrometer.
Seam Impression: The seam impression refers to the lining inside the can. It is what makes it easy for the seam rollers to push the lid over the body of the can and hook every part together, giving them the strength to push against the seaming chuck. Care has to be increased during this process since too much pressure can damage the container.
Lid Wrinkles: Lid or cover wrinkles are common in seaming, especially when different amounts of pressure are applied on the same can. The differences in radius also play a huge role in the creation of wrinkles. During an inspection, it is important that wrinkles are ironed out as they could threaten the integrity of the can and everything stored inside them.
When it comes to getting a proper can sealing machine, there are a number of factors that you have to keep in mind in order to get the best deal out of it. With so many brands out there, the following are the factors you can focus on to narrow down your search.
Capacity: How big is your production volume? If you plan to run a small packaging venture from your garage, then you don’t need complicated can sealing machines, but if you have a huge demand, then you will need to find bigger can sealing machines that are able to handle thousands of canning in a day.
Budget: The prices of can sealing machines vary from one brand to another and from one size to another. Bigger seaming machines will cost you more compared to smaller ones. A well-known brand will charge you higher as you are buying quality. Be mindful of your budget as you search in order to find what fits your needs perfectly without breaking your bank for it.
After-Sales Services: How involved is the can sealing machine supplier? Do they do a follow-up? Do they have warranties? These are some of the questions that should direct you to the right supplier. Can sealing machines are sophisticated and you will need help to get them running. You need to get machines from someone who will be there to help you get settled and figure out how to work the machines.
Quality: The quality of the end product matters the most, and that should be your biggest concern when getting a can sealing machine. It has to deliver as promised with as few defects as possible.
