Adhering heat sensitive labels to containers with hot melt adhesives

摘要

In order to apply "hot melt" adhesives to thin plastic film labels for glass containers without distorting the labels, a "hot melt" adhesive which is thixotropic is melted at 350 DEG F. and is continuously worked to maintain its viscosity at a fairly low level while being cooled to about 110 DEG F., at which time it is applied to the label. The label is applied to the glass bottle and the resultant labeled bottle will have the property of being able to withstand pasteurization temperatures, as well as refrigeration temperatures, without having the label separate from the bottle.
