Commonly used packaging process

four-color printing

1, the so-called four colors: green (C), magenta (M), yellow (Y), black (K) four kinds of ink, all colors can be mixed by these four kinds of ink, the final realization of color graphics.

2, the most common and most common printing, different substrates printed on the effect of different.

spot color printing

1, spot color printing refers to the printing of a special ink to print the color, more bright than the four-color mixture. Commonly used is special gold, special silver.

2. There are many spot colors. Refer to Pantone Color Card. The spot color cannot realize gradual change printing. If necessary, add four-color printing.

Glue

1. After printing, the transparent plastic film is laminated to the surface of the printed matter by hot pressing to protect and increase the gloss. The surface is bright, as shown in the figure below.

2. The most basic process of carton surface treatment. Similar to the varnish, but the glue can enhance the hardness and tensile properties of the paper.

Over-dumb glue

1. After printing, the transparent plastic film is laminated to the surface of the printed matter by hot pressing to protect and increase the gloss. The surface is matte, as shown in the figure below.

2. The most basic process of carton surface treatment is similar to that of varnish, but the glue can enhance the hardness and tensile properties of the paper.

over UV

1. The printed matter needs to be locally brightened on the prominent parts to make the local pattern more three-dimensional effect.

2. Cooperate with the dumb glue process for printing, and there is no effect when the light glue is passed.

Hot stamping

1. hot stamping is the use of hot-pressing transfer principle, the anodized aluminum in the aluminum layer transferred to the substrate surface to form a special metallic luster effect.

Printing raw materials are gold, silver, red, green, blue and other colors, but hot stamping can only be monochrome, a wide variety of colors, but not what color market.

Bump

1. A group of concave templates and convex templates corresponding to yin and yang are used to place the substrate in between, and the embossed concave-convex graphic is pressed out by applying greater pressure.

2. All kinds of thickness paper can be, cardboard can't do bump.

Spray code

1. The process of printing the logo (production date, shelf life, batch number, enterprise logo, etc.) on the product with the inkjet printer.

2. Can print simple character patterns, more flexibility.

composite bag

1. The compound bag is suitable for vacuum packaging or general packaging of food, electronic products, chemical industry, medicine, tea and other products.

2. Can do the process and paper is basically the same, can screen, printing, hot stamping.

Blister

1. Blister is a transparent material, the main raw material is PVC, PE, or PET.

2. Can directly replace the paper to make the box, can also be combined with business card printing.

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

4. can screen printing, printing, also can be hot stamping.

It can be printed on the machine, but the printing cost is high, and a small amount of production is generally only used for silk screen printing.

OPP bag

1. OPP bag is a stretchable polypropylene, which is a kind of plastic, in fact, it is a plastic bag.

2. Before packing the outer box, the product should be set with an OPP bag to make it look clean and hygienic.

3. Different materials and PP plastic bags, PE plastic bags.

4. With high transparency, more brittle and other characteristics, but also according to customer needs to print a variety of patterns and punch.

EVA

1. The chemical name is ethylene-vinyl acetate copolymer. The finished product made of it has the characteristics of good softness, shockproof, non-slip and strong pressure resistance.

2. Used in packaging and inside, used to fix and protect the product.

3. There are a variety of colors to choose from, the surface can be done flocking, wrapped flannel process, enhance the visual effect.

Sponge

1. It is a porous material with good elasticity. The density of the holes is different, the elasticity is different.

2. Used in packaging and inside, used to fix and protect the product.

3. There are a variety of colors to choose from, generally used directly, no longer superimposed process.

Heat Shrink Bag

1. It is a transparent bag made of materials with strong shrinkage at a certain temperature to protect the packaging.

Only used to protect the packaging, no longer do other processes.

Commonly used packaging materials

Single powder

1. For commonly used carton materials, the thickness of the paper ranges from 80g to 400g, and the higher thickness requires two pairs.

2. One side of the paper is light and one side is dumb. Only the smooth surface can be printed.

3. Can achieve a variety of colors of printing, unlimited for color.

4. The commonly used surface treatment processes after printing are: over-gluing, over-uv, hot stamping, and bump.

Pit paper

1. Compared with ordinary paper more straight, bearing capacity is stronger.

2. Commonly used have single pit, double pit, three pit.

3. Can achieve a variety of colors of printing, but the effect is not as good as single powder.

4. The commonly used surface treatment processes after printing are: over-gluing, over-uv, hot stamping, and bump.

Cardboard

1. It is used to make gift box structure, with a layer of single powder paper or special paper mounted on the surface.

2. The commonly used colors are black, white, gray and yellow.

3. Cardboard thickness also has various grades, according to the load-bearing needs to choose.

4. If the single powder is mounted, the process is consistent with the single powder paper box. If it is special paper, most of it can only be hot stamped, and some can realize simple printing, but the printing effect is not good.

Specialty Paper

1. There are many kinds of special paper. Here we only talk about what we use in packaging materials: emboszed paper, pattern paper, pearlescent pattern paper, metal pattern paper, gold paper, etc.

2. These paper through special processing, you can enhance the quality of packaging texture. Embossing and embossing cannot be printed, only surface stamping, star color, gold, etc. can be printed in four colors.

gold and silver cardboard

1. Use UV transfer technology to coat a layer of UV oil on the surface of the paper through a blanket, and then transfer the light column film or a specific pattern to the printing paper through the roller, so that the surface of the paper produces the effect of laser paper.

2. Can only use UV machine printing, all kinds of pattern effect can be achieved, more texture than ordinary paper, and have different kinds of luster. But the cost is relatively dry.

Other materials common process

Baking paint

1. In the polished to a certain degree of roughness of the substrate, spray a number of layers of paint, and by high temperature baking shaping.

2. There are many kinds of colors, refer to Pantone color card. But only solid color, can not present gradient.
