Printing Tips Of Primary Color Paperboard Food Packaging

      In the field of food packaging, for household products such as baking products or comfort food, the natural brown appearance of corrugated paper reflects a healthy appearance and has a retro meaning.Printing Tips Of Primary Color Paperboard Food Packaging

Printing Tips Of Primary Color Paperboard Food Packaging

        In the past, in the food manufacturing industry, “corrugated paper” had only one meaning: American cheese biscuits. Today, however, both bread makers and hamburgers agree that corrugated paper is a multi-purpose primary color cardboard used to make eye-catching packaging, which is enough to strengthen the brand image and increase sales.

      Food manufacturers have always believed that SBS paperboard with smooth and white appearance is the only material that can give the brand a noble image and maintain consistent performance in the high-speed molding and filling process. Only in a large number or old-fashioned and plain packaging, will the primary color paperboard be used.Printing Tips Of Primary Color Paperboard Food Packaging

      However, today, primary color cardboard is widely used in the packaging of retail food or food services such as cup and bottle packaging, fast food cartons, pancake boxes, bread boxes and so on. There are many different factors for the rise of primary color paperboard: Printing Tips Of Primary Color Paperboard Food Packaging

      due to its fiber composition, primary color paperboard provides the greatest strength: its smooth and consistent surface performs well in the environment of high-speed manufacturing; It has a striking natural brown appearance and good pattern reproduction effect. It also allows food manufacturers to respond to the new challenges and demands of the market with a unique and alternative image.Printing Tips Of Primary Color Paperboard Food Packaging

     For example, the complexity of quality in the food sector forces manufacturers to reassess the way new products are launched. Customers demand higher standards in taste, appearance and packaging. However, the clamshell shaped corrugated board or corrugated board represents a higher quality image. If the fast food restaurant only uses wax paper to pack hamburgers, it will not be accepted by guests.Printing Tips Of Primary Color Paperboard Food Packaging

     Compared with the past, food packaging also takes on more responsibilities to convey market information. It ranges from basic corporate trademarks to complex cross activity details. Today, it is not uncommon for film companies or amusement parks to attract fast food consumers with discounts or other market messages. Anyway, the space of advertising billboard is empty. Why not use it to repeatedly promote or guide consumer power to partner enterprises?

     Beverage manufacturers also use packaging as a publicity tool. Many manufacturers print promotional messages on the crash barrier in 12 or 24 bottle cartons.

     These and countless other examples show that the use of packaging has been very different from before. It is no longer just to prevent collision during transportation.

Selection of corrugated paper

     In order to meet the manufacturer’s new demand for packaging, corrugated board provides some characteristics quite different from bleached board. For household products such as baking products or comfort foods, the natural brown appearance of corrugated paper represents health and retro. Steak houses decorated with country style logs can maintain a consistent image through corrugated packaging. Apart from others, the unique appearance of corrugated paper is a striking contrast in a large number of white packaging, which makes the product more prominent.Printing Tips Of Primary Color Paperboard Food Packaging

     Because many food packages are designed to enhance their convenience or portability, the strength of corrugated paper is another advantage. The strength of the takeout package should be sufficient to support the customer’s meal. Similarly, the beverage cup must be able to maintain in a humid environment so that the coffee will not flow to the customer’s lap.Printing Tips Of Primary Color Paperboard Food Packaging

     Strength is also the main consideration of frozen food, because the packaging of frozen food cannot deform, tear, twist or absorb too much water in the freezing / thawing cycle. In these aspects, corrugated paper is more practical than SBS.Printing Tips Of Primary Color Paperboard Food Packaging

Effect optimization

     Corrugated board can be printed by flexo, gravure or lithography. Although large-scale integrated processing plants are very familiar with all kinds of paperboard, stores that are small or printed on corrugated paperboard for the first time may have some questions about how to achieve the best effect. Here are some suggestions for novices:

◆ color reproduction

     To achieve the correct color reproduction on corrugated board, you need to be more alert than SBS, because the darkness of the board itself will make the ink look different from bleached board on corrugated board, and the more eye-catching color effect is the best. Soft colors are most difficult to achieve the required ink strength, opacity or wear resistance

     If necessary, add a little white first, it will be easier to make soft or light colors close to the needs. Printing technology is becoming more and more sophisticated. Some people even use ultraviolet ink to make the color effect better.Printing Tips Of Primary Color Paperboard Food Packaging

     Almost all ink manufacturers have developed inks that can be used on primary color paperboard. Therefore, before starting any work, they should consult them and decide the best formula. Many of them have sample books. Some even have samples of ink on different paperboards.Printing Tips Of Primary Color Paperboard Food Packaging

◆ ink demand and coating

     Because corrugated board is not coated and looser than SBS, special consideration should be given to inking and coating. For example, the primary color paperboard needs more ink. The upper layer of cheap varnish can make the ink more eye-catching, while high solid and water-based coatings are more effective than real solvent varnish. Printing Tips Of Primary Color Paperboard Food Packaging

     Coating a layer of clay based high solidifying agent and acrylic acid can also inhibit the separation of ink pigment from resin and prevent free pigment from remaining on the surface of paperboard.Printing Tips Of Primary Color Paperboard Food Packaging

     In addition, surface coating will increase the wear resistance of ink, especially for objects completely covered by ink. In flexographic printing, the ink roller with large ink hole can upload ink and coating better on the sketch board. In addition, in order to strengthen the surface contact when printing on corrugated paper, soft flexible plate and backing paper are considered.Printing Tips Of Primary Color Paperboard Food Packaging

◆ processing performance

     Because some uncoated corrugated board materials are quite loose and bulky, dust may be generated during processing. There are several steps to reduce dust. Before working, make sure that the vacuum suction cup is in good condition, and make necessary adjustments to achieve the best state of operation. Bellows vacuum suction cups are most effective for corrugated paper.

     Improve smoothness. The smoothness of corrugated board cannot be compared with SBS board because of the manufacturing method of corrugated board. However, many food manufacturers like the rough appearance and touch of corrugated board and the image it represents.Printing Tips Of Primary Color Paperboard Food Packaging

     The smoothness of primary color paperboard depends on the manufacturer. The printer needs to evaluate the surface characteristics of the paperboard to determine the suitable paperboard. If a smoother surface is required, paper mounting, glue or foil paper is also helpful. In addition, paper mills are also gradually strengthening the smoothness of corrugated paper.Printing Tips Of Primary Color Paperboard Food Packaging

◆ die cutting performance

      Corrugated board has excellent embossing, die cutting and die engraving performance because of its strength and predictable fiber characteristics. However, for high strength and “high memory” primary color fibers, the notch must be deep enough to avoid rebound. The knife must be sharp. Because of the high fiber strength of corrugated paper, the notches required on the punching line are less and smaller.Printing Tips Of Primary Color Paperboard Food Packaging

◆ adhesion

      The resin adhesive with high solidity and high viscosity is suitable for low-temperature bonding because it will not “Penetrate” a large amount of paperboard. Traditional hot melt adhesives also play a rapid role in corrugated paper and multi-layer coated corrugated paper. Corrugated board has better paper walking performance under the high-speed box pasting and folding machine because of their light weight.Printing Tips Of Primary Color Paperboard Food Packaging

◆ supplier relationship

     Customers must choose a corrugated paper factory that can supply continuously and has an appropriate work schedule. In order to educate the first contact with corrugated paper, the supplier will also provide technical service experts to solve questions on site.Printing Tips Of Primary Color Paperboard Food Packaging

     By helping food manufacturers respond to the new challenges of the market, primary color corrugated board has become widely popular in many retail food and food service industries. With these tips in mind, printers and processors will be able to respond to customer needs and achieve ideal performance and maximum efficiency. ◎Printing Tips Of Primary Color Paperboard Food Packaging
