Chapter 9
Opening Cans, Bottles and Other Containers on Shabbath and Yom Tov
4.a. Packets which are usually emptied of their contents and thrown away immediately upon being opened, such as miniature packets of sugar of the type commonly used in hotels, may be opened on Shabbath and Yom Tov.
4.b. One should be careful, in opening such packets, not to cut or tear through lettering or pictures, as mentioned in paragraph 12 below.
4.c. It is, however, allowed to cut them open along a line specially marked for that purpose, if indeed they are thrown away once opened.
