If some monomers or resins do not react completely, unreacted "acrylic acid" components will remain, forming a pungent, sour odor. This is especially common with domestically produced raw materials.

Pigment dispersion also needs to be optimized. Highly dispersed pigments can reduce particle agglomeration and improve the density of resin coating, thereby reducing the risk of adhesion loss.

The rise of graveure water-based ink, with its dual advantages of "uncompromising on environmental protection and uncompromising on color," is injecting new possibilities into high-end floral paper packaging.

As a printing material that comes into direct contact with food packaging or the tableware itself, flexo water-based ink is facing higher requirements for safety and functionality.

Flexo water-based ink for tableware, with its environmentally friendly characteristics and increasingly mature high-precision printing capabilities, is gradually becoming the mainstream choice in the tableware decoration printing field.

Flexo UV ink for paper, with its core competitiveness of "super adhesion," completely changes the traditional impression of paper printing as prone to fading and lacking durability through advanced light curing technology and materials science.
