The Supersealer MBS medical band sealer, is our flagship sealer for the medical industry. We have partnered with Code Tech and Keyence to fulfill FDA compliance dates for UDI requirements.

The Supersealer MBS is a rotary band sealer designed to meet ISO11607-2, ISO13485, ISO9001 and EN868 standard requirements for the medical industry. The sealer continuously seals a wide range of medical packaging materials including Plastic, Tyvek, Mylar, Pet, Coated Tyvek, paper and plastic, laminated foil and metalized foil bags.

The Supersealer MBS runs continuously, it is not an intermittent motion sealer. OK Sealer has developed a package that integrates a UDI Thermal Ink Jet coder with the sealer, along with a Keyence Reader. All of these components are run through one HMI. Our process is continuous therefore sealing and coding is done in one step.

The sealer is manufactured in stainless steel and all its interior parts are stainless steel or anodized aluminum. There are exterior calibration ports for air pressure and heat.

The Supersealer MBS has the most advanced monitoring package on the market. We now monitor the heaters and coolers with electronic pressure regulator with analog input. We have sensors for wrinkles and band breaks.  Latest feature to the sealer, we now added a sensor to monitor if the bag is straight or crooked with a reject station at the exit end of the sealer.

The HMI can hold up to 15 recipes. When you push a button all parameters change such as heat, speed, air pressure and height, so you are ready to run your pouch in a matter of minutes. These are some of the aspects of the Supersealer MBS that make it the most superior medical sealer on the market today.

Our process is to first speak with the customer to discuss their application with our engineering staff. We then move onto receiving samples of the pouches/bags and product for evaluation and testing. OKI thoroughly tests each application and produces sample seals using the end user's pouches/bags filled with their product. The sample seals are then returned to customer, so that they may do their own seal integrity testing and provide approval.

Throughout the years OK International has strived to be different and unique compared to our competitors. We have really listened to our customers and prospects who want their packaging needs to be taken care of in the best possible way, in an efficient, but still the most cost effective way. As OKI has always said; “Brands are built on what people are saying about you, not what you’re saying about yourself”. With this package, the Supersealer MBS and the Code Tech iJET with Keyence scanner customers will be able to package their products in the most reliable and cost effective way, meeting the compliance dates for UDI requirements.
