Heat sealing is one of the key factors which determine whether medical instruments and equipment can be deemed safe or not. Heat sealing is also used to package products whose integrity needs to be maintained. For medical products, along with ensuring that they are infection free, heat sealing also ensures that the instruments and equipment incur no damage when they are moved or shipped out. Heat sealing is given utmost importance in medical procedures, because ultimately the packaged medical instruments and equipment are used to save human lives.

Several factors have to be taken into consideration to ensure that heat seal equipment passes all the required standards of safety. They include – but are not limited to – checking the pressure of the sealing, checking temperature of the sealing, and testing the strength of the seal.

Main Factors to Consider

·      Dwelling Duration

The dwelling duration commonly means the time during which the heating components come in direct contact of substrates. This is done during the packing process and it can go about in two ways: either one sided or both sided. The method that is used to measure the dwelling duration is of utmost significance because different instruments and equipment require different control parameters for this. The slightest variation in the temperature used to seal the material during the sealing process can impact the entire procedure in a major way.

·      Establishing the Proper Temperature

An effective heat sealing process is ensured with the help of two materials. The sealant layer is carried in one of the materials. The temperature of the elements is increased to a certain level. This either melts or activates the agents that are responsible for effective sealing and safe packaging of the instruments. Time, pressure, and most importantly temperature are the factors that have to work in tandem, otherwise the desired strength of the seal will be quite hard to achieve. This means that after the sudden rise of temperature to activate the sealing agents, the temperature has to be lowered gradually to increase the dwelling duration. In other words, the perfect temperature that you are looking for is the one that effectively activates the agents or melts them, without being harsh enough to damage the sealing equipment.

With these factors in hand, you can guarantee that no harm comes to the medical instruments and equipment when they are moved or shipped. In short, you will be ensuring that when the packages are opened, whatever they contain will not be a cause for harm.
