This article will summarize the 8 main stages of packaging manufacturing.

Step 1: The packaging company exchanges ideas with customers

In addition to the common types of packaging available on the market, most customers prefer unique, specialized designs for their products. For completely new packaging samples, the packaging company will work with customers to:

  • Understand customers’ ideas about the type of packaging to produce.
  • Understand the purpose that customers want when using this type of packaging: Luxury paper bags or shipping carton boxes, labels for export products or need POSM to introduce new products.
  • Decide the quantity and the deadline for the packaging manufacturing process.

The manufacturer will have the basis to consult the material, size, content, image shown, number of colors and the best production technique.

Step 2: The packaging company will design the structure and product images

In this step, the packaging company will visualize customers’ ideas and needs on appropriate design software. Includes shape, structure, information and photos of the packaging.

The structure design not only shows the shape but also calculates the capacity, bearing capacity when stacked, even measures the feasibility of hanging or displaying products on shelves.

Step 3: The packaging company prints and samples the products

After structure and image design, the packaging company will make a real design pattern to check the shape, information on the product, color, capacity, bearing of the product to adjust if necessary.

The purpose of this step is to check the viability of the package, customers approve the sample, approve the color before mass production.

Thanks to proof prints (printed samples), both parties can minimize errors before producing paper packaging such as:

  • Informative content, images, typo, unreasonable content
  • Fonts
  • Sizes
  • Colors or errors related to handwriting alignment
  • Margins, layout of bricks, letters

Compared to fast printing, proof printing is significantly superior because the color resolution mode of proof printing is similar to offset printing.

Step 4: The packaging company will make molds and process printing

One of the most important steps in the packaging process is molding. Molding is the process of arranging prints on the size of the paper to be printed, placing color scales, tram colors, and safety cradles so that the post-printing process is easy.

Set the CMYK color, the color scale at the 4 corners and 2 upper and lower edges of the print so that when printing, the printer recognizes C, M, Y, K colors and easily aligns the colors.

Next, arrange the printouts in the most optimal way, in this stage, the designer will calculate and measure to have a quality product but still ensure the economy, including:

  • Printouts are arranged to fit the size of the paper (to reduce the waste of paper)
  • Arrange suitable prints for the most convenient and quick process after printing.
  • Screen printing is the process of creating images to be printed on aluminum sheets as offset prints, exporting zinc for CTP.

Step 5: The packaging company prints the product

The packaging company will use the offset printer to print the images of the packaging on paper. Depends on the design, the machine will print in 4 or 5 colors.

Offset printing has many outstanding advantages, making it the most favored techniques. The outstanding advantages of offset printing include:

  • The image quality is higher, sharper and cleaner than printing directly from the print to the paper because the rubber pad is evenly applied to the surface.
  • Applicable on many surfaces, including non-flat surfaces (such as wood, cloth, rough leather)
  • Easier to print
  • Last longer

  • Cutting, groving: cut and groove printed sheets according to the designed shape.
  • Stamping, embossing: emphasize a detail on the packaging such as logos, slogan, texts on or under the surface
  • Glossy/blurred lamination: covering the surface of publications with a layer of polymer film.
