Box Packaging for Cosmetic Products
Boxing refers to folding paper boxes or micro-corrugated paper boxes made from two materials: cardboard and micro-corrugated paperboard. Packaging box materials can be divided into two categories: one is plain paper and the other is corrugated paper. The papers commonly used for packaging boxes include gray board, single-ply board, white board, fancy card, silver card, gold card, platinum card, laser card, etc.
“White background white board” refers to: white copper and single copper. The common point between white copper and single copper is that both sides are white. The difference is: “white copper” is smooth on one side and not smooth on the other side. In layman's terms, the front side can be printed, but the back side cannot be printed; “single copper” has coated surfaces on both sides, and both sides can be printed. “Gray background gray board” refers to this type of paper, but it is not used for packaging boxes; “gray background white board” is what is called “gray copper paper,” meaning the front side is white and can be printed, while the back side is gray and cannot be printed. Generally, white card is also called “white background white board” paper, which is the abbreviation for general quotation (except for special white cards, such as platinum card and silver card).
White cardboard, black cardboard
White cardboard has a variety of applications and is commonly used in cosmetic, pharmaceutical, cigarette, wine, and food packaging. Its characteristics are that the paper material is overall sturdy and thick, has a high whiteness, a smooth surface without rough spots, is easy to print on, has good ink acceptability, and a high gloss. We usually choose this paper material first when printing cosmetic pouches. The reasons for choosing this paper material are: first, the paper does not easily lose ink during printing; second, this type of paper has good opacity, high fold resistance, and is not easily torn. Third, the paper has high density. In addition to these advantages, white and black cardboard can be suitable for various surface treatment processes. Common production processes include lamination, varnishing, hot gold/silver stamping, hot blue, hot red, hot green gold, embossing, UV coating, and so on. When making mask boxes, high-quality white cardboard can also be die-cut into various required box structures to achieve the packaging effect desired by the customer.
Gold cardboard, silver cardboard, laser gold card, and multicolored gold cardboard.
Gold and silver cardboard can be used more frequently in mask packaging, and there are many options for cosmetic inner packaging, outer packaging boxes, and daily bath product packaging. Such as packaging for toothpaste, health care products, medicine, and gift boxes. The biggest feature of gold and silver cardboard is that it looks more luxurious, beautiful, and classy visually. Gold and silver cardboard are specialty papers. They are made by laminating a gold and silver aluminum foil layer onto white cardboard. Printing on gold-printed cardboard is slightly more complicated due to the material. Quick-drying printing ink is required during printing, and because the surface of gold and silver cardboard is easily scratched, lamination protection is needed in the subsequent process. After lamination, surface embossing, hot stamping, UV, and other processes are applied. When using gold and silver cardboard, the production cost will be slightly higher than that of regular white cardboard. However, to enhance product sales and aesthetics, using gold and silver cardboard or choosing other gold cardboard colors might be the way to go!
Kraft paper and specialty paper
The advantages of kraft paper are its visibility, tear resistance, and good water resistance, but its surface is loose and somewhat rough. Most prints are single-color black. If the surface requires 4-color or spot color printing, the print effect may be slightly worse than on other papers because the paper itself is yellow. In post-processing, if hot stamping and UV are applied without lamination, the hot stamping section will be incomplete or unable to be hot stamped because the paper's surface itself is not smooth and fine. The surface treatment process after lamination is better.
Internationally renowned cosmetic boxes often use specialty paper. Special papers include embossed papers with various surface textures, pearlescent papers in different colors, tactile papers, colored corrugated papers, etc. Cosmetic boxes or packaging boxes made from special papers are very luxurious. They can be printed in color and then hot-stamped, embossed, and so on in post-processing.
General mask packaging boxes or cosmetic packaging box customizations are mostly made from white, gold, and silver cardboard, with paper weights chosen at 350 g or 400 g. The box structure is predominantly a tuck-top box. Depending on the total weight of the mask and the skincare product, the bottom can be reinforced. The bottom can be designed as a hook-bottom box (with glue on the bottom to increase load-bearing capacity) or an automatic bottom box. In terms of packaging technology, white cardboard can be hot-stamped, UV-printed, embossed, and debossed after coating. Art paper can be directly screen-printed and hot-stamped. Gold cardboard can be hot-stamped, UV-printed, embossed, and debossed after coating.
Method and process for producing cosmetic packaging boxes
Cosmetic packaging can be divided into mid-range and luxury packaging. The production methods and processes for cosmetic packaging boxes are inseparable from several common procedures. To achieve a higher grade, luxury cosmetic packaging often incorporates additional post-production processes or different box structures to enhance visual appeal and the overall quality of the packaging, thereby helping to boost sales. However, no matter how things change, they are fundamentally the same. Any cosmetic packaging box, other product packaging, or gift packaging must go through the following processes before it can be made. So what are their procedures, methods, and production processes?
The first and most important step in cosmetic packaging is printing. Printing manufacturers use offset printing (commonly known as color printing). Color printing is used to print the desired color effects by mixing the four primary colors—magenta, yellow, cyan, and black ink. Specialty gold, special silver, special red, and so on are classified under special color printing methods. In addition to standard process printing, the printing method must be adjusted for different printing materials. For example, various gold-colored card stocks use UV printing. The more spot colors in the design file provided by the customer, the higher the printing cost. When printing cosmetic color boxes, printing gold and silver also provides a high-end effect to enhance the premium grade. Before printing, the following processes need to be prepared. First, select or design the structure of the paper box. Customers who have a sample can have it made according to their sample. Why design the box structure first? Because there is a die-cutting process in the paper box finishing, which makes the box structure standardized. Before designing, you can create the artwork according to the designed die line. After designing and confirming the file, you need to make the plates first. Four-color printing uses four screens, and each spot color requires a spot color plate. The more spot colors, the more plates.
Process
After printing, a surface treatment process is required. Among them, the direct effects of laminating and varnishing processes are to protect the printed surface from scratches. They are common production and processing methods. For example, when making color boxes, when gray board paper is printed in darker colors, if it is not varnished, the entire surface will appear duller and more worn, whereas the printed surface after varnishing will enhance overall glossiness, giving people a visually fresh impression. However, cosmetic packaging rarely uses the varnishing process. More other processes such as laminating, hot stamping, hot silver, UV, convex and concave, embossing, etc., are used to enhance the luxury and prestige of the packaging product.
To cut off the head
Die-cutting is a necessary process before gluing the box. The box structure selected before designing the artwork is turned into a cutting die. When die-cutting, the cutting die is mounted on a die-cutting machine. After a professional die-cutting master aligns the position and angle, it is cut into a flat shape according to the die's form. The die-cutting size deviation is approximately 1 mm, which is within the normal range.
Pasting the box
Useless edges and corners have been removed from the printed surface after die-cutting. The next step is to glue the box into shape. When gluing the box, it is necessary to carefully align the line positions. If there are high and low lines (the top and bottom lines are misaligned) and skew (the gluing line exceeds the gluing position line), the product is considered defective. The manufacturer will conduct random inspections of the product during box gluing. Qualified products can be packaged and shipped to customers for use.
Based on the above understanding, when we need to customize cosmetic packaging boxes, we first select commonly used paper materials, such as high-white cardboard, various gold cards, silver cards or laser-cut cardboard, and specialty papers with different embossed textures, like cowhide cardboard. The weight used is usually 350 gsm. Next, choose the post-production process. The common method is to coat white cardboard with a matte film and then hot-stamp gold, silver, or laser onto the surface, combined with embossing technology to raise the logo or other patterns. Gold cardboard must be coated before surface UV treatment. General art paper can be directly UV coated or coated and then hot-stamped or undergo other processes according to different requirements. Specific processing procedures can be customized to meet customer needs. The most common box type is the tuck-top box. Bottom-lock and bottom-gusset boxes are also common. Die-cut boxes can be used for gift packaging or an entire cosmetic packaging set. They are recommended for lightweight cosmetics.
