All National Plastics clamshells are designed with friction fit channels around the exterior of the package.
Should your packaging require more positive seal, we also offer a handheld clamshell sealer or can refer you to a
manufacturer of clamshell sealing equipment.
Hand Held Clamshell Sealer
This electric powered hand held clamshell sealer creates a 1/2" x 1/4" sealer and works on the majority of our stock
clamshells. Priced at just over $100, these sealers are ideal for those with relatively low volume applications.
