1. Basic Properties of Hi-Selon
| Type | Film thickness (μm) |
Complete dissolution temperature (°C) |
Tensile strength (MPa) | Elongation (%) |
|---|---|---|---|---|
| C-type | 17–60 | 2–5 | 26–30 | 170–380 |
| S-type | 20–80 | 2–5 | 32–51 | 170–380 |
| M-type | 20–22 | 25–32 | 26–32 | 170–380 |
| H-type | 25–32 | 51–60 | 36–59 | 170–380 |
*Measurement conditions: 20°C, 65% RH
*The above values are values measured by Nippon Gohsei, and are not standard values.
2. Relationship among water temperature, film thickness and dissolution speed
- Hi-Selon is available in various types, from those that are soluble in cold water to those that are soluble in hot water.
- Dissolution speed varies according to water temperature, film thickness, and dissolution method.
3. Changes in solubility when packaging alkali substances
- Hi-Selon S-400 is recommended for packaging alkali substances, as it has a low insolubilization tendency.
4. Heat-sealing temperature and strength (C-200)
*Sealing temperature varies according to film type, moisture content, and type of heat sealer.
- Hi-Selon can be easily heat-sealed.
*Hi-Selon usage precautions
- Hi-Selon is hydrophilic. Do not use or store the film in high temperature and humidity. Use Hi-Selon packaging machines in a humidity controlled room.
- When not in use, tightly wrap Hi-Selon film rolls in polyethylene film. Do not leave them exposed. Hi-Selon film rolls should be left inside a temperature and humidity controlled room for 24 hours before they are mounted on a packaging machine.
- Preliminary tests should be conducted before using Hi-Selon, because insolubilization may occur depending on the content of the Hi-Selon package.
