Intro to Packaging Ch. 7

What type of board might be used for a set-up box?

A heavy, low-grade chipboard.

What are the disadvantages of the airplane-style tuck carton?

An airplane-style tuck carton has only minimum friction fit, and both cut edges face the front display panel of the carton.

Describe the general process by which a carton design is brought into production.

As with carton sign-offs, the product process will vary by project and the customer's and supplier's policies. The carton design process starts with an in-depth review of the customer's needs and objectives. The customer needs to share all technical and marketing expectations. The carton designer will develop one or several designs to meet the customer's stated objectives. The customer inspects the hand sample and gives the approval to proceed to the next step. The customer's approval, or sign-off of a hand sample, starts the carton production process. Digital-dimensionally correct records of the approved design are forwarded to graphic arts and die-making departments. At the same time as the dies are being made, the art department develops the graphic image the will appear on the carton. When proofs have been approved, printing plates are made and mounted in the press. The customer is usually called in to give final press approval.

What is the difference between a Beers tray and a Brightwood try?

Beer trays are knocked down for shipping. Brightwood trays nonfattening once erected.

A company has specifications for several folding cartons. One is listed as being 90mm x 20mm x 40mm, and another is listed as being 20mm x 40mm x 90mm. Explain these descriptions.

Carton dimensions are given in the order of length, width and depth, with length and width defined as the carton opening. Depth is perpendicular to the opening. The first carton is 90mm in length, 20mm in width, and 40mm in depth. The second carton is 20mm in length, 40mm in width, and 90mm in depth.

Why is it a good idea to erect and fill folding cartons soon after they have been produced?

Cartons are best run within 90 days of manufacture.

At what points is a customer typically asked to sign off an a carton project?

Depending upon the nature of the product and the customer's and supplier's policies, the following are normally the minimum of "sign offs" requested in a carton project: a.) structural design, hand samples, CAD sample b.) one up die sample, production die sample c.) digital proofs, artwork layout on carton die line d.) on press for final production approval

Discuss retailing or merchandising needs that will have a major impact on carton design.

Does the product need to be supported or held in the package? How will the product be delivered and displayed in the store?

What is double gluing, and where would you specify it?

Double gluing is the gluing of both the inner closure panels and the outer closure panels to provide a complete sift-proof seal. It is specified for a product that requires sift proofing.

What is the difference between a vertical end-loading carton, a horizontal end-loading carton and a top-loading carton> Where would you use each?

Horizontal end-loading tube-style cartons are essentially the same as vertical; end-loading tube style, except that the filling orientation has changed. Top-loading cartons are shipped as unglued blanks. Horizontal end-loading cartons are for products such as food trays for pizzas and cakes. Vertical-loading cartons are for products such as granular or powdered items.

Discuss the nature and critical importance of providing a sign-off.

It should be clearly understood that each sign-off constitutes a legally binding contract, and it is the customer's responsibility to ensure that every detail is correct at every stage of production.

Himes and 1-2-3 closures are usually put on what kind of cartons?

Manually assembled cartons for heavier products.

Which will be paper MD in a typical tube-style folding carton?

Most tube-style folding cartons have gran or "paper machine direction" (MD), running around the carton perimeter (i.e., crossing the carton body scores).

What paper would you specify for an ice cream box?

Paperboard coated with either polyethylene or wax.

What are the principal advantages and disadvantages of a set-up box?

The advantages of a set-up box are: upscale image, many types of decoration possibilities and appearances, they make a convent kong-term storage unit and serve as a low-cost shipper. Some disadvantages are: boxes cannot be knocked down flat and empty boxes in storage occupy as much space as when they are full. Also, set-up boxes are not designed for high-speed manufacturing.

Which panel on a folding carton is generally regarded as the principal display panel?

The front, or principal display panel, is the panel situated between the two side panels on the carton blank (i.e., the main panel not adjacent to the glue flap).

Name four machining or filling needs that will have a major impact on carton design.

Tuck or glue ends, vertical or horizontal loading, size of opening required and an irregular shape.

Name four product characteristics that will have a major impact on board selections.

Weight? Is product wet? Is the product greasy or oily? Will the product tear or burst the package?

In what direction is a scored paperboard folded: away from the valley or towards the valley?

Scored paperboard is folded away from the valley side of the score.

What is a slit lock?

Slit-lock closures incorporate small slits between the tuck flap and the top closure panel. When the carton is closed, slits engage shoulders cut into the dust flaps, securely locking the flap into place.

Discuss factors that would lead you to decide whether to design a tuck-end carton or a glued-end carton.

The type of product you are packaging and the packaging operation are the first two factors to consider. Additional factor come into play for a self-contained package: Will there be one entry or repeated entries into the package? Will the consumer wish to see the product before purchase? Also consider the nature of your packaging operation.

What is working score?

The working scores are normally the part not adjacent to the glue flap on the carton.

Irregular carton shapes have an inherent disadvantage. What is it?

Through irregular shapes may provide a distinctive shelf appearance, they are more difficult to pack and ship. Obtaining machinery that will handle eye-catching shapes also can be a problem. Approach irregular carton shapes with caution.
