FAQ

How do the Gracin paper substrate properties contribute to its performance as a printed release paper for die cutting?

The Gracin paper substrate properties are meticulously engineered to create a synergistic effect that benefits both printing and die-cutting. The high density and smoothness of the base paper provide an ideal surface for high-resolution printing, ensuring ink lays flat and does not feather or penetrate. Simultaneously, these same properties—especially the high internal bond strength and dimensional stability—prevent the paper from delaminating or fracturing under the sharp impact of a die-cutting blade. This results in clean, sharp label perimeters and allows for the efficient stripping of the waste matrix, which is critical for high precision die cutting release liner applications. Essentially, the substrate acts as a stable, robust canvas that can withstand the rigors of conversion while presenting a perfect surface for graphics.

Yes, the Gracin release liner release force range is highly customizable through adjustments in the silicone coating formulation and application process. Standard grades cover a wide spectrum, but manufacturers like Anhui Hengbo New Material Co., Ltd. often work closely with clients to develop tailored solutions. For instance, if a customer uses a very aggressive, high-tack acrylic adhesive, a custom grade with a tighter, more controlled release force can be engineered to prevent ooze and ensure safe unwind. Conversely, for sensitive medical hydrogels, an ultra-clean, low-release version can be produced. This customization is key to solving specific application challenges and is a core service offered by advanced material suppliers.

What are the storage recommendations for Gracin Release Printed Paper to maintain its specifications?

To preserve the critical Gracin release paper technical specifications such as release force and flatness, proper storage is essential. Rolls of Gracin Release Printed Paper should be stored in their original packaging in a cool, dry, and dark environment. The ideal temperature range is between 15°C and 25°C (59°F and 77°F) with a relative humidity of 50% ±10%. It is crucial to store rolls upright on their cores, not lying flat, to prevent deformation. Exposure to direct sunlight, extreme temperatures, or significant humidity fluctuations can alter the release chemistry and cause the paper to curl or warp, compromising its performance as a high precision die cutting release liner. Always practice first-in-first-out (FIFO) inventory management.

Is Gracin Release Printed Paper suitable for use with food-contact adhesives and labels?

Gracin Release Printed Paper can be manufactured to be compliant with food-contact regulations, but this is not a universal property of all grades. Compliance depends on the specific formulations of both the base paper and the silicone release coating. For applications involving direct or indirect food contact, it is imperative to specify this requirement to your supplier. They can then provide a grade that meets relevant international standards, such as FDA CFR 21175.105 or EU 10/2011, ensuring that all components are non-migratory and safe for the intended use. Always request and retain the manufacturer's compliance statement or certificate of analysis for your records.
