IMPROVEMENTS IN ADHESIVES AND THEIR APPLICATIONS

摘要

Adhesive compositions and their applications are disclosed. Further, apparatus suitable for applying glue is also disclosed and which can be used for sealing or welding non-gelatin films to achieve strong tamper proof and leak free welds. Products thus produced include capsules, pouches and other packaging constructions. Other products include tables, powders and compacted powders enrobed by films. The films, adhesives and film modifying compositions used can be safe for human consumption and may find use as a wall material of an ingestible delivery capsule, e.g. containing a dose of a pharmaceutical preparation.
