The integrity and efficiency of the can seaming process is an essential component in the business model of dry food product companies. Whether you are producing nuts, potato chips and crisps, cereals, gravy powder, stocks and seasoning, flour, rice or pasta, you want to be able to rely on your can sealers to ensure that your canned dry food does not deteriorate. Our wealth of experience in the canned foods sector enables us to provide you with the equipment and support that you need to guarantee a quality canned product.
Ensuring a long shelf life is essential when packing dry food products, and cans offer optimum protection against both oxygen and moisture. Tinplate, aluminium, PET and composite cans can all be used for packing, but paperboard or rigid paper containers are a very popular choice for dry snack foods such as mixed nuts as well as rolled oats, muesli, porridge, chocolate and drinking powders and other low moisture and low fat products.
The multiple components used in the rigid paper can differentiate it from the alternatives. Barrier materials of paper, foil and film provide protection against oxygen, moisture and light and extend shelf life up to eighteen months, while the rigidity of the container protects the contents during transportation. It can also be resealed with a plastic plug lid or over-cap.
Hermetically double seaming a composite can calls for specialized seamer-tooling geometry and seam specifications, and at Innovus Engineering we have decades of experience with these applications thanks to our close collaboration with paperboard can manufacturers and their customers. We know how important each aspect of the can sealing process is to the integrity of your product and the reputation of your brand, from using the correct can ends to setting the can closer with the appropriate base pressure, pin height and roll settings.
Whatever your choice of can type, sealing your dry food product in a low residual oxygen atmosphere is vital for maintaining product freshness and taste. Our Innovus VG model can seamers produce residual in-can O2 levels of 1%, depending on the product and container specification. They work by vacuumising the filled can and then back flushing it with nitrogen directly into the seaming chamber before double seaming. This vacuum and gassing process brings considerable gas usage savings over traditional open can gassing methods.
