A portable device utilizes electromagnetic fields to create hermetic seals on containers, typically those made of plastic or glass, with foil liners. This process involves a handheld device passed over the container’s opening, inducing a current in the foil liner. This current generates heat, melting the liner’s sealant layer and bonding it to the container, creating a tamper-evident and leak-proof closure commonly used for products like pharmaceuticals, food, and beverages.
Portable sealing offers a flexible, cost-effective alternative to large, automated systems, especially for smaller production runs or applications requiring mobility. It contributes significantly to product safety and preservation by preventing contamination, leakage, and counterfeiting. This technology has evolved from larger, stationary industrial equipment to become a versatile tool applicable across various industries, benefiting from advancements in battery technology and miniaturization.
