Many companies order custom boxes to house information and announcements about new products, to package software, CD/DVD’s and other electronic media, or to have an option over brochures, pocket folders and binders. This article will help you understand your vast options when requesting custom boxes.
Some typical types of boxes include:
– Turned edge,
– set up boxes
Most people are familiar with shipping cartons made out of thick brown (or kraft) C-flute corrugated board. Inspecting a side cut of C-flute corrugated, you notice it is very wide วิจารณ์มวย and thick; good for shipping things but not good for accepting the kind of graphics required to market a product.
E-flute corrugation is only 1/16th ” thick, much thinner than the C-flute mentioned above. On some requirements, F-flute or B-flute corrugated may be used. F-flute is very thin (even thinner than E-flute) and is used for very small boxes or boxes that require intricate die cutting. Surprisingly, B-flute is thinner than C-flute but thicker than E-flute. B-flute is about 1/8th” thick and is used for heavier weight projects.
Corrugated board is usually stocked by the mill and is defined by colors. Brown, Oyster White, White.
White is the most expensive board and most sought after for graphic usage.
Combinations are available, by special order. Oyster over Kraft or Bleached over Kraft are common. Normally the wavy part of the corrugated board is Kraft.
Decoration of Corrugated
Litho lam: Many customers prefer their corrugated boxes have the graphics printed on 80# litho paper, which can be film, laminated and mounted to the corrugated. (we call this labeling). Film lamination seals the printing and enables the box hinges to be bent without cracking. The label is attached to the corrugated board before die cutting. The film lamination can be either glossy or matte (also called de-lustered). A label can be applied to the outside or the inside of the box (also called the liner) or both. The label usually covers the entire box.
Flexo printing: Imagine a big rubber stamp and you now have a good idea of flexo printing. If complex 4 color process graphics is not required then flexo printing may be an alternative to consider. Because flexo printing is not sophisticated, you can only expect the quality of a 65 line screen. This differs dramatically from the 150 line screen quality common in litho printing (labeling). The most cost efficient type of flexo printing is a flood coat (overall coverage) of a color. Stock printing plates can be used to put the color on the board. However, if graphics or type is required to be reversed out of the solid field or you want to have positive type or graphics, a custom printing plate will have to be made. Flexo plates are priced per square inch. The more graphics or type, the more expensive.
Silk screen: For quantities too low to create expensive flexo plates, silk screening can be a cost effective alternative. Modern technology has made silk-screening almost as clear and sharp as offset printing. We start with your artwork either on a computer disk or good black and white copy. A film positive is made from the art and mounted on to a screen that has been coated with an emulsion. The screen and artwork (on a film positive) are exposed to light for a few minutes. The black of the artwork blocks the emulsion from hardening. The film positive is removed from the screen and the screen is washed with a high-speed water spray. The emulsion where the artwork was is washed away leaving a stencil of the artwork on the screen. The screen is mounted to a press and a squeegee pushes special paints through the screen onto the material for your box.
Silkscreen paints are hand mixed to come as close as possible to a specified color but it is not an exact science. We silk screen on many different color materials and a hand mixed Pantone color match will look different when put on colors other than white.
Turned edge boxes and set up boxes: Whereas corrugated boxes have “raw edges” where you can see the corrugation, turned edge differ because the board is covered by the wrap. Instead of using corrugated board, we use different weights of chip board. In small quantities, these boxes are made by hand. In larger quantities, box making machines are used. Turned edge boxes tend to cost more than corrugated boxes but they have a more finished look. Because chip board is used, these boxes tend to weigh more than the equivalent corrugated box. Set up boxes are in the category of turned edge boxes. These boxes are commonly referred to as gift boxes and jewelry boxes. Both turned edge and set up boxes can be wrapped in a variety of coverings, film laminated printed paper, linen cloths, fancy paper stocks.
