| How much tackifier should be used when formulating packaging adhesives with polyethylene polymers? |
| |
| Generally, 15 — 30% of the formulation should be tackifier. Excess tackifier can result in a brittle adhesive with reduced cold-temperature resistance and insufficient amounts of tackifier can result in very short open times and reduced hot tack or green strength properties. For more information, see Eastman publications WA-26 and WA-49.
