Abstract
A heat-activated sealing tape for manufacturing or sealing a carton or other article. The tape is composed of a paper layer, a layer formed of oriented plastic film which is adhesively laminated to the paper layer, and a heat-activatable adhesive exposed for use in adhering the paper-plastic film laminate to an object. The heat activatable adhesive is inactive at ambient temperatures. When exposed to low temperature heat sealing conditions, the adhesive is activated and enables the tape to be adhered to the article to be sealed. The sealing tape is designed for ease of handling and reduction in waste, and is adaptable for use in existing automatic and semi-automatic equipment for manufacturing or sealing cartons.
