UV technology makes gift box packaging fuller

UV process is one of the common processes in the packaging industry. Deep processing of packaging gift boxes, such as hot stamping, lamination, and embossing, has become very common.

What is UV process

The UV process is to apply a layer of varnish (glossy, matte, inlaid crystal, glitter, etc.) on the pattern you want. It mainly increases the brightness and artistic effect of the product, protects the surface of the product, and has high hardness. , corrosion-resistant and friction-resistant, not prone to scratches.

UV process is a packaging process that uses ultraviolet light to dry and solidify ink. It requires ink containing photosensitizers and UV curing lamps to complete the transfer of ink. UV ink has been used in offset printing, screen printing, inkjet, Pad printing and other fields.

Advantages of UV process

1. Improve product performance

The UV process has good packaging suitability for most packaging. UV printed gift box, the ink color is bright and bright. At the same time, since the UV curing process is a photochemical reaction process, both the ink layer and the varnish layer have the advantages of strong adhesion, durability, water resistance, chemical corrosion resistance, wear resistance, and anti-aging.

2. Improve production efficiency and economic efficiency

Drying through light curing does not require a heat source, does not contain solvents, and the curing time is very short. The general UV process can achieve a line speed of 400 meters/minute, which can greatly improve production efficiency.

After being connected to the machine for glazing, packaging processing processes such as die-cutting, creasing, gluing and hot stamping can be completed immediately. This can also reduce storage costs and financial pressure for raw materials and finished products. At the same time, due to the low energy consumption of UV curing, the daily operating costs are also greatly reduced.

3. More environmentally friendly

The entire curing system of the UV process is a solvent-free system, that is, a 100% solvent-free formula without VOC, which exactly meets today's environmental protection requirements.

This is another important feature of UV curable ink. Because the solid content of UV ink is close to 100% after curing, it contains almost no VOC (volatile organic compounds), that is, no or very few volatile organic compounds are emitted during the curing process. It will not cause harmful environmental pollution, waste less, save energy, and do not have to worry about handling harmful flammable and explosive materials. It is an environmentally friendly ink.

4. Strong adhesion

The chemical substances in UV ink form a high molecular three-dimensional network polymer through a cross-linking reaction. Therefore, using UV ink can make the packaging ink layer strong, quick-drying and cross-linked. Such an ink layer has high friction resistance and Chemical resistance.

Even if the packaging gift bag is folded, the UV printed part will not be affected and can withstand the strong radiation during laser printing again, so UV ink can be used for outer packaging printing that requires wear resistance.

5. Fast curing

UV ink will only dry under the irradiation of ultraviolet light. Even if the ink is stored in the ink fountain for a long time, its performance will remain stable and no skin will form on the ink roller. Once irradiated by ultraviolet rays, the ink dries instantly. Generally, it only takes 1/10s to completely dry and fix on the surface of the substrate. Traditional heat-setting inks and sheet-fed offset printing inks may take minutes or even days to dry completely. Therefore, printing jobs with UV curing inks has a short delivery time and is comparable to flexo printing and gravure printing. Improved printing production efficiency.
