THE Sprinter ES-S, available from Packovation , seals paperboard lids to trays with various heat sealable coatings.
The sealing principle in this case is based on heat generated within the paperboard by means of microwave energy.
The sealable coating thus approaches melt point from this energy and forms a seal between tray and lid after compression and cooling.
Trays filled with product are conveyed into the machine. A lid is automatically placed onto each tray. Opposite sides of tray/lid pass through electronic activator and are sealed. The tray is then rotated 90° and remaining two sides are likewise sealed.
This method of electronic heat sealing gives excellent seals at higher speeds and with less power consumption than other conventional sealing methods.
Like all Sprinter machines, the ES-S bears the CE mark to show that it complies with the stringent EU safety standards.
Key features include:
* Heat generated by microwave energy.
* Gives excellent seals.
* High speed.
* Less power consumption.
