    Many industries, especially in the food and beverage industry, have experienced a rapid increase in their production costs. The most practical alternative chosen by several brands is to turn to specialty packaging equipment for their production line and extend product shelf life.

    For your business to generate higher profits using the canning method, you have to upgrade your packaging line to the latest technologies. But, investing in modern packaging equipment without any experience or prior knowledge is not financially feasible. It can result in a great loss to your business’ bottom line.

    So in today’s discussion, we will be giving you six of the common things you need to know if you are into can packaging. Through the following list, you can save time, reduce expenses, and limit the possibility of errors.

    #1 Understanding what double seam is.

    Some packagers think that the closures are compressed onto the body of the cans. This is one of the most common misconceptions regarding can packaging. Modern manufacturers of cans design lids and cans in a way that your products are packaged in containers using the least possible raw materials. But, they still make sure to maintain the functionality and strength of the lids and cans.

    A hermetic double seam is formed by rolling the flanges of the lid and can body with each other in the first roller operation. Then the second roller operation completes the double seam by tightening the loose seam created in the first operation. You can read more about the formation of a double seam and the terminology here.

    #2 Knowing the seam specifications.

    The majority of can manufacturers include seam specifications of their lids and cans. The specifications provide the actual measurements of the following:
    • Countersink
    • Overlap
    • Cover hook
    • Body hook
    • Seam thickness
    • Seam height
    Each measurement usually has a specific value (.064” for instance) within an acceptable +/- 0.002” range. If all of the above measurements satisfies this range, the manufacturer of the cans and lids guarantees the formation of a hermetic double seam.

    #3 Awareness of the three major can seamer adjustments required.

    A can seamer machine is designed for hermetically seaming your lids and cans within your manufacturer’s seam specifications. Similar to any other equipment with metal to metal contacts, a can seamer machine also requires proper adjustments and maintenance.

    Below are the three major can seamer adjustments required:
    1. Adjustment on the 1st seam roller operation
    2. Adjustment on the 2nd seam roller operation
    3. Adjustment on the pressure in the base plate
    No timeframe is available as to when you should be making these adjustments. However, you need to make sure that you lubricate and clean your can seamer properly. This ensures that you will achieve optimum performance before any adjustments are needed to be done.

    #4 Spotting deformities in a double seam.

    Before you start packaging your products every day, you should try to double seam using an empty container and lid. Once seamed, take the measurements of the seam to make sure that you are within your can manufacturer’s seam specifications.

    Perform this process according to the Quality Control procedures established by your company. Base it on the number of cans you are closing per shift or every time you change the can size. Also, you should inspect if the seam is uniform and smooth. Visible double seam defects may mean that you need to adjust your can seamer.

    #5 Not all cans are the same.

    Each manufacturer of cans produces a lot of same-sized cans. But different manufacturing facilities are used to produce the lids and cans in various double seam specifications. Different tooling is required for closing different types of lids and cans and this is a fact for all manufacturers of cans. So be very careful when you are sourcing lids and cans from resellers or distributors.

    Every time you purchase cans and lids, always ask for the can manufacturer’s specifications regarding the can seam. This is among the toughest challenges of a packager when sourcing cans for their application.

    #6 Understanding the can packaging process.

    Set aside time to learn the process of packaging because this will help you save a lot of money and time. Through this, you will be sure that your workers have adequate training to maintain and operate your equipment. Also, they will learn how to properly inspect can seam defects which will guarantee that you will produce reliable and leak-proof hermetic double seams.

    Conclusion

    Knowing the above-mentioned things will help you guarantee that your can packaging process is an efficient and reliable one. It is always better to be familiar with the basic things first before starting with the actual process. Aside from saving time and money, you will be able to generate higher revenues as your customers will surely be satisfied with your packaged products.

    By the way, if you haven’t yet found the right can seamer manufacturer for your application, try LPE’s can seaming machines for simplifying your canning process. They also offer consultation services to ensure the maximum performance of your equipment in your specific application.
