    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.

    Abstract translation: 通过将片材加热至高于聚合物的结晶熔点的温度,将热可回收的聚合物片材涂覆在固体片材的热可密封的密封剂上,优选通过辊子将密封片材料施加到加热的聚合物 同时聚合物片材处于能够活化密封剂以便将其粘附到聚合物片材上的温度。 聚合物片材可以在加热之后并在施加密封剂片之前进行火焰刷涂。 该技术对于用作用作外壳的环绕套筒的片材特别有用,因此具有邻近其相对的纵向边缘的封闭轨道。
