热收缩膜仅是辐照交联技术众多的应用之一。各类塑料经交联反应后大大提高其耐环境应力开裂、耐热、耐油、耐燃、耐化学药品腐蚀、抗蠕变性和电性能等综合性能，并显著提高了耐热温度，拓宽了应用领域。经辐照交联处理的电线、电缆、各类管材、板材广泛应用于汽车、飞机、电子、建筑、大型工程等。而经辐照交联处理的聚乙烯泡沫塑料等则在绝缘、建筑、救生、隔热等方面具有特殊的优势。
Heat shrinkable film is only one of the applications of irradiation crosslinking technology. After cross-linking reaction, all kinds of plastics greatly improve their comprehensive properties such as environmental stress cracking resistance, heat resistance, oil resistance, fire resistance, chemical corrosion resistance, creep resistance and electrical properties, and significantly improve the heat-resistant temperature and broaden the application field. Wires, cables, pipes and plates treated by irradiation and crosslinking are widely used in automobiles, airplanes, electronics, buildings, large-scale projects, etc. However, the irradiation crosslinked polyethylene foam has special advantages in insulation, construction, life-saving and heat insulation.
注：热收缩膜包装与一般的真空包装是不同类别的技术：真空包装袋的塑料膜较厚，需经抽真空系统将包装袋内抽成低真空后封口，以便于运输和贮存。热收缩膜很薄，加热后会紧贴在包装物上防潮保鲜，被包装物品更直观、紧凑便于运输。
Note: heat shrinkable film packaging and general vacuum packaging are different types of Technology: the plastic film of vacuum packaging bag is thick, which needs to be sealed after the vacuum system is used to pump the bag into low vacuum, so as to facilitate transportation and storage. The heat shrinkable film is very thin. After heating, it will cling to the package to prevent moisture and keep fresh. The package is more intuitive, compact and convenient for transportation.
