Common Process Of Packaging Products

CMYK Printing

1. The so-called four colors are: cyan (C), magenta (M), yellow (Y) and black (K), and all colors can be mixed by these four inks, finally displaying color pictures and texts.
2. Four-color printing is the most common and common printing, and different effects will be printed on different substrates.

Spot Color Printing

1. Spot color printing refers to printing the color with a special ink, which is brighter than the color mixed with four colors. Common spot colors are special gold and silver.
2. There are many spot colors. With reference to Pantone color card, spot colors cannot realize gradient printing. If necessary, four-color printing will be added.

Gloss Lamination

1. After printing, a transparent plastic film is attached to the surface of printed matter by hot pressing, which plays a role in protecting and increasing luster, and the surface is bright, as shown in the following image.
2. Gloss lamination is the most basic process of packaging box surface treatment, which can enhance the hardness and tensile properties of paper.

UV Varnishing

The prominent parts of the printed matter need to be locally polished and brightened, so that the local patterns have a more stereoscopic effect.

Hot Stamping

Hot stamping uses the principle of hot press transfer to transfer the aluminum layer in anodized aluminum to the substrate surface to form a special metallic luster effect.

Printing materials are gold, silver, red, green and blue, but hot stamping can only be spot color.

Emblossing

Adopt a set of concave and convex templates corresponding to pictures and texts, place the printing stock between them, and press out embossed concave and convex pictures and texts by applying greater pressure.

Paper of various thicknesses can be emblossed, but cardboard can’t.

Code-Spraying

The process of spray printing marks (production date, shelf life, batch number, enterprise logo, etc.) on products with a code spraying machine.

Simple character patterns can be sprayed and printed with greater flexibility.

Blister

Blister is a transparent material, and the main raw materials are PVC, PE or PET.

?It can directly replace paper to make boxes, and can also be matched with cards to make packing boxes.

?It can be used to fix the product inside the package, which is called blister inn.

Screen printing, printing and hot stamping are available.

It can be printed on production line on machine, but the printing cost is high, and screen printing is generally used for small-scale production.

OPP bags

OPP bag is tensile polypropylene, which belongs to a kind of plastic, which is actually a plastic bag.

Before loading the outer box, the product should be put in an OPP bag, which can make the product clean and hygienic.

Different materials include PP plastic bags and PE plastic bags.

It has the characteristics of high transparency and brittleness, and can also print various patterns and punch holes according to customers’ needs.
