Vacuum Impulse Sealer

Flexibility and Performance

hawo impulse vacuum sealers have a number of features ensuring that evacuation, gas purge and sealing are user-friendly, safe and easy. The 8 mm (0.3 inch) wide seal seam and the customisable settings options for the process parameters therefore offer maximum flexibility when it comes to choosing packaging materials.
All impulse vacuum sealers are equipped as standard with two nozzles (AP2-V models) for even and rapid vacuum or gas purge. The hv 800/1100/1300 AP4-V versions have four nozzles, making them one of the most powerful impulse vacuum sealers on the market .

The optionally available ‘bag support device’ allows machines also to be set up at an angle or vertically. The machines are designed for high volumes in multi-shift operation. The vacuum impulse sealers can be customized with a vacuum level sensor. The impulse vacuum sealers are available in bar widths of 450, 630, 770, 970 and 1,270 mm (18, 25, 30, 38 and 50 inches).

The hv 460 AP2-V impulse vacuum sealer in particular has been certified in accordance with the Fraunhofer IPA qualification mark for clean rooms of air purity class 6, compliant with ISO 14644-1.

The correct reprocessing process of medical devices consists of the steps of washing & disinfection, packaging and sterilisation. The instruments can only be called sterilised when they are packaged before the sterilisation. The single-use (!) packaging, made from laminated poly film and a porous material (Tyvek® or medical grade paper) is permeable for the sterilisation medium (e.g. steam, plasma, Formaldehyde FO or Ethylenoxide ETO), but not for bacteria or microorganisms. Only by following this reprocessing sequence and by using professional heat sealers to seal the instruments as well as professional packaging material can the sterility up to the point of use as well as the aseptic presentation of the instrument be guaranteed.

Medical devices delivered in a sterile state should be packed to ensure that they remain sterile until the point of use. The validation of packaging processes is crucial to ensure that sterile barrier system integrity is attained and will remain so until opened by the users.

The international packaging standard ISO 11607-2 as well as the Technical Specification draft ISO/DTS 16775 explain how packaging processes should be validated. The international packaging validation guideline gives guidance how to validate packaging processes. During the validation of the heat sealing process the optimum sealing temperature of the packaging materials used has to be evaluated and established. At this temperature, the process then has to deliver optimum seal seams that are strong enough and peelable.

Professional heat sealing equipment for closing sealable pouches and reels (preformed sterile barrier systems) are essential for this. Hawo therefore offers sealing devices whose processes can be validated according to ISO 11607-2, the Technical Specification draft ISO/DTS 167751 and in harmony with the international packaging validation guideline. The models marked with ‘V’ feature an integrated function for regulating and monitoring process parameters – the ‘V’ is the key! Sealing devices from Hawo therefore guarantee efficient and reproducible packing, even for large volumes of instruments.
