TOSS Machine Components, Inc., a manufacturer and distributor of impulse heat sealing components and supplies, has announced the launch of its new advanced seal and cut heat seal bands. Designed to address the specific needs of the medical and life sciences industry, TOSS claims its seal and cut bands provide ‘unparalleled’ precision, efficiency, and customization.

Offering a validatable heat-sealing process, they are ideal for applications such as implantable medical devices and sterile package sealing according to the company.

Three key offerings—Beaded Bands, T-Profile Bands, and Custom Seal-Cut (CSC) Bands—stand out for their ability to deliver consistent, reliable seals while cutting polymeric films in a single process. Each band incorporates unique design features and cutting-edge technology tailored to various applications.

The Beaded Band design includes tapered edges, eliminating sharp and high-temperature outer edges for safer handling and consistent performance. The bead itself retains more heat than adjacent edges, enabling precise cutting without overheating the sealed areas. Additionally, the space behind the bead is designed to avoid contact with the underlayment backing material, preventing heat loss and ensuring efficient operation. This band is ideal for high-cycle processes where reduced material waste is paramount and dependable seals ensure product integrity and sterility.

The T-Profile Band provides a greater mass per unit length and therefore is able to retain more heat, making it effective for cutting through thicker film stacks or multi-layered films. Featuring a sharp cutting edge and a relieved back design, this band minimises contact with underlayment backing, ensuring efficient heat distribution. The T-Profile Band’s ability to cut and seal simultaneously makes it particularly suited for applications where durable seals and high cycle rates are essential. Furthermore, depending on shape and application, the T-Profile band can be curved to make contour shapes.

Finally, Custom Seal-Cut (CSC) Band offers unmatched customisation for the most demanding applications. This band combines a tapered band with a cutting wire, allowing manufacturers to tailor the width and cutting wire thickness to their specific needs. Cutting wires can be positioned along the centreline or at the edge of the band, enabling precise cutting action at multiple locations.

This level of customisation is ideal for packaging operations in the medical and pharmaceutical industries. From implantable medical devices to sterile package sealing for pharmaceuticals, the CSC Band provides the flexibility and precision required to meet the stringent demands of the packaging industry.

All TOSS seal and cut bands are designed to create consistent, repeatable seals every time, making them compatible with a variety of automated and customized impulse heat sealing systems. To guarantee the reliability of the seal, these bands, when paired with a PIREG heat seal controller, can include a heating and cooling cycle, ensuring the films seal completely before pressure is released.

TOSS heat seal bands are an essential tool for medical device applications, which require precision, safety, and efficiency in their packaging processes. By minimising material waste, enhancing seal quality, and providing unparalleled customisation, TOSS continues to set the standard for advanced packaging solutions.
