<p>Multiple laminate made up from two single films, of which the inner film in contact with the viscous contents containing organic solvents, is composed of polyethylene, backed by an outer layer of polyamide. This in turn can be backed by Al foil, and this protected on the outside by an e.g. glass or foil, cover layer. The pack is easily handled, dispensed, prevents vapour escape, keeps content, consistency and re-closes without difficulty.</p> |
