Claims11
A solvent blend useable for tackifying a surface of a multilayer oriented shrink film, said solvent blend comprising:
- 20-80 vol. % of at least one terpene selected from the group consisting of α-Pinene and d-Limonene;
- 10-70 vol. % of n-heptane;
- 10-40 vol. % of at least one compound selected from the group consisting of 1,3-dioxolane, 1,4-dioxane, tetrahydrofuran, methyl ethyl ketone, cyclohexanone and ethyl acetate,
- wherein the solvent blend is free of any other terpene, alkane, ether, ketone or ester, and the solvent blend is free of:
- 30% α-Pinene/50% n-Heptane/20% 1,3-Dioxolane,
- 20% α-Pinene/60% n-Heptane/20% 1,3-Dioxolane,
- 30% α-Pinene/40% n-Heptane/30% 1,3-Dioxolane,
- 20% α-Pinene/50% n-Heptane/30% 1,3-Dioxolane,
- 30% d-Limonene/35% n-Heptane/35% 1,3-Dioxolane,
- 20% d-Limonene/40% n-Heptane/40% 1,3-Dioxolane, and
- 20% p-Cymene/40% n-Heptane/40% 1,3-Dioxolane.
