Removable labels feature low peel force and can be removed cleanly from the surface after a period of time without contamination. These require a low-tack adhesive that can be removed without residue after rigorous aging.

Currently, a widely adopted low-cost removable adhesive design involves adding a small amount of crosslinking agent to a general-purpose low-tack pressure-sensitive adhesive to increase its molecular weight and reduce its tack. However, this design does not alter the polarity or microstructure of the pressure-sensitive adhesive, resulting in only a short period of removability.

After exposure to high temperature and humidity or after a certain period of storage, pressure-sensitive adhesives may still fully wet the substrate, exhibiting permanent adhesive properties and making them difficult to completely remove.

Sinograce Chemical's removable label adhesive offers three key performance advantages: peel force, removability, and substrate adhesion.

Removability

Removable pressure-sensitive adhesives exhibit a wide range of removable properties on various surfaces.

Surface adhesion

Surface adhesion is a key property of removable pressure-sensitive adhesives. They exhibit excellent adhesion to paper substrates. For film-based surface materials, a suitable surface treatment (such as double-layer coating) is required to achieve good adhesion.

Applications

Various single copper, mirror copper, mirror wet-strength paper, thermal paper, mirror aluminum paper, aluminum foil labels, and advertising materials.
