Abstract
A heat-recoverable polymeric sheet is coated with a solid sheet of heat-activatable sealant by heating the sheet preferably to a temperature above the crystalline melt point of the polymer, applying, preferably by means of a roller, the sealant sheet to the heated polymer sheet while the polymer sheet is at a temperature capable of activating the sealant so as to adhere it to the polymer sheet. The polymer sheet may be flame-brushed after heating and before application of the sheet of sealant. The technique is particularly useful for sheets intended as wrap-around sleeves for use as enclosures, and which thus have closure rails adjacent opposing longitudinal edges thereof.
