Product Spotlight - Plastisol Lined Caps


Plastisol lined metal caps are essential for canning, preserving, pickling and other food storage methods. SKS offers plastisol lined metal caps to provide an attractive look to your products, while creating an effective seal for an extended shelf life.

Plastisol Liners

The plastisol liners that we carry feature plasticized PVC resin sprayed around the perimeter. Plasticizing during the manufacturing process causes the PVC to become more flexible and malleable. The plastisol liner begins as a solid liner within the caps. As it is heated, the liner becomes softened and pliable. As the liner cools, it solidifies and begins to create a hermetic seal, which is airtight, tamper evident, durable and can extend the shelf life of your products, when applied correctly.
Plastisol Liners

Plastisol liners can be activated through many different canning processes, including pressure, water bath and open-kettle. The best method can be determined by the batch size, equipment available and your products and preferences. SKS highly suggests testing your canning method with the plastisol lined metal caps to ensure compatibility, especially before large production runs. For more information regarding canning, be sure to visit the NCHFP website for publications, resources and an informative FAQ section.

Plastisol Lined Metal Caps

SKS has exceptional metal plastisol lined cap options for glass containers with continuous threaded necks. Our 70G metal plastisol lined caps are available in an array of colors including black, white, gold, silver and red. These 70G metal caps include buttons in their centers that pop up if the vacuum seal is broken. The buttons depress when a seal is initially created and will pop up when the jar is opened. This feature gives your container another level of tamper evidence, ensuring your customers that the product contained is fresh. These metal caps are also available in gold with black print stating "Button Pops Up When Original Seal Is Broken" with arrows directing the eye to the button. For glass containers you would like to use with a plastisol liner that does not have the 70G neck finish, SKS has a variety of sizes in white and black plastisol lined caps.
Plastisol Lined Metal Caps

The black and white metal plastisol lined caps in smaller sizes do not have buttons, but you may be able to apply a shrink band to certain compatible glass bottles for additional tamper evidence. These metal caps are also available in white. Consider purchasing our glass jars in bulk quantities, allowing you to choose different colors of compatible metal plastisol lined caps. This technique helps to provide cohesion in the size and shape of your packaging, making it easy to distinguish between flavors, product types or levels of spice.

Two Piece Plastisol Lined Metal Caps

Two piece plastisol lined metal caps are regaining popularity as a packaging option in the food preservation industry. These metal caps are available in silver and gold and can be purchased in three kits featuring different glass jars. The plastisol lined lids are designed for one-time use and offer the same hermetic seal as the one piece plastisol lined caps, but do not include a button. The band is reusable and screws onto the glass jar once the plastisol lined lid has been secured. The bands and lids can be purchased separately, or together as a kit. The two piece design can be used in different canning processes and could potentially aid in removing more air, reducing the chance of mold after sealing.
