Impulse Sealer hm 450/630 AS

Brand: Hawo

The  hm 450 AS and hm 630 AS impulse sealing devices are used for sealing sealable pouches. The footswitch-operated and magnetic sealing system makes them ideal for constant use (for example in hospitals and the medical industry).

SKU: hm450AS | hm630AS Category:



  • Suitable for Sealable pouches and reels corresponding to EN 868-5 and EN ISO 11607-1 and Thermoplastic film (eg. PE, PP, PVC)
  • Automatic electronic sealing and cooling timer facility
  • Integrated film roll storage
  • Integrated film cutting device
  • Constant contact pressure
  • Reproducible process
  • Optional tray



Quickly graspable functions and thought through solutions make perfect operation possible. There is room for up to three roll formats side by side. At insertion, the film roll is automatically and exactly positioned. The cutting blade runs in a guiding profile and is securely parked away from the cutting area. In addition, the device can be fastened to the wall with a special mounting.


Safe Packaging

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.
