HEAT SHRINKABLE TUBE OF POLYVINYL CHLORIDE FOR PROTECTING STEM OF CUT FLOWERS

摘要

A heat shrinkable tube of polyvinyl chloride for covering the stem of cut flowers, said heat shrinkable tube having the following properties: (a) a shrinkage at 60 DEG C. of 8% or less in the lengthwise direction, and from 10% to 20% in the circumferential direction; (b) a shrinkage at 80 DEG C. of 20% or less in the lengthwise direction, and from 35% to 45% in the circumferential direction; (c) a shrinkage-initiating temperature in the circumferential direction of from 40 DEG C. to 55 DEG C; (d) a softening temperature of from 40 DEG C. to 55 DEG C; and (e) a thickness of from 50 mu m to 100 mu m.
