Improvements in or relating to heat-shrinkable tubular film material. |
摘要 |
<p>In the manufacture and use of tubular casing material, a starting material having heat-shrinkable properties is partially shrunk to a controlled reduced calibre and then is further shrunk during use. The shrinking may either take place during use, for example by partially shrinking tubular film material over a stuffing horn 2 in a shrinker 6 (Figure 1) or may be carried out during manufacture by partially shrinking a length of tubular film material to a controlled reduced calibre before sale (Figures 2 and 3).</p> |
