Clam Shell Sealers

Clam shells are made of a hinged sheet of thermoformed plastic that surrounds the product and can be secured with a heat or ultrasonic sealer. Sealing the clam shell keeps all of the contents together in new condition, and it also allows the purchaser to view the product prior to purchase.

Ultrasonic clam shell sealers remain cool to the touch. Rather than relying on heat, they perform their function with the use of high frequency vibrations. These machines can seal much faster than the constant heat sealers, making them the better choice for high production.

We recommend having your clam shells tested. Some clam shells will not properly seal with heat or ultrasonics due to recycled content or poor quality material. Our recommendations for those shells is to use staples or clear stickers. If you have further questions, you can reach us through the contact page.
