How can I tell if I have old Instapak Quick®, or new Instapak Quick® RT bags?
Instapak Quick® bags are silver colored and must be heated prior to activation. This is done by placing them in the Quick® Warmer for at least one half hour prior to use. Quick® RT bags are blue colored and are activated at room temerature (RT), right out of the box. These answers apply to the original version of Instapak Quick® packaging, which requires a warmer.
