Induction Cap Sealing Liquid & Powder Products

Did you know that the type of product you are sealing is as important as other factors such as line speed and cap size? Dry solid products like popcorn kernels, tablets and capsules are the simplest to seal. However, liquids and powders require additional application considerations.

Sealing Liquid Products

When sealing liquids, the temperature of the product and the environment should be taken into consideration. A cold filled product usually requires more sealing energy than an ambient or hot fill product. This is because it takes more energy to heat the foil liner to the temperature required to melt the polymer and bond with your container.

Another consideration with sealing liquid products is if the product will come in contact with the liner and has any caustic properties such as with chemicals, or even tomato based products. In these cases a liner with a barrier layer will help protect the integrity of the seal.

Ideally the land area of the container should be free of any product residue prior to capping. If the product is flood filled or if there is a concern that there will be a liquid residue on the land area prior to capping, you should consult with Enercon’s application experts.

In many cases the residual product will be pressed off by the application torque of the cap, or it will evaporate during the sealing process. However products that may leave an oil type residue may undermine the sealing process and should be carefully reviewed.
