Heat Sealer - Constant Heat Sealer
Constant heat sealers are used for the sealing of foil, mylar or polycellophane bags. A constant heat seal differs from an impulse heat sealer in that the heating element is always on (constant heat). This constant heat provides the ability to seal a heavier bag. Polycellophane bags are commonly seen in supermarkets where spices are packaged and displayed or on gift baskets. Foil bags are commonly used to seal coffee. A constant heat sealer is a specialty item not for common bag sealing operations.
