Is there an industry-standard tolerance that would be applied to the assembled dimensions Length, Width, Depth of a 2pc carton? I would question whether multiple processes should lead to alternate tolerances when compared to a single process 1-piece carton. The particular carton I am trying to apply tolerance to is a 2pc Partial Overlap Top, HSC bottom where the width panels are die cut and the other scoring off of a press and then offset stitched within the length panel for reference.

No allowance is given for carton size, caliper, substrate or complexity of design in this specification. One other note to toss in here.

Half slotted containers are similar to regular slotted containers except that they have only one set of flaps. The opposite side of the box is open, which allows it to slide over an item. Ideal for: large and heavy objects such as refrigerators and washing machines. These are custom corrugated boxes developed to exact specifications depending on customer requirements. Boxmaster can manufacture custom boxes with FULL color, available in all styles and custom sizes.

Ideal for: unique products with special requirements such as cosmetic product boxes, toy product boxes, gift product boxes. The outer flaps overlap the full width of the box making it especially resistant to rough handling. All flaps are the same depth, and their depth equals the width of the box.

Ideal for: heavy objects that require extra support such as refrigerators and washing machines. These are simple unglued boxes that need to be folded when assembled. These are great for shipping narrow items. Ideal for: vitamin packaging, retail packaging, coffee packaging, tea packaging. Board strength are all the factors that define how strong the box should be. There are a number of questions you must ask yourself before you can accurately asses how strong a particular box should be manufactured to be such as:.

Boxmaster provides you with two different levels of customization options when selecting box strength. The first is the flute type and the second is using the edge crush test. This is called the boards corrugation. Flutes are essentially the reinforcement that make up the board. As well as providing stacking strength, flutes also provide insulation that protects products from sudden temperature changes. They provide the second highest arch size. B flutes provide good stacking strength and crushing resistance.

Ideally used for canned goods and displays. They are the medium between A flute and B flute and are very common. C flutes provide good cushioning, stacking and printing properties. Ideally used for glass, furniture and dairy. The board profile is super-thin which in turn reduces box size and saves store space.

E flutes provide the greatest crush resistance and a super printing surface which make it an excellent choice for die-cut custom boxes.

Packaging 101: The Corrugated Box

History of Corrugated Boxes The more people learn about corrugated boxes, the more they realize that there is nothing "basic" about them. With every box made up of three sheets of paper, the combinations are limitless.

The Ultimate Guide to Corrugated Box Designs

Corrugated Trays Corrugated Trays are basically trays to hold other objects.By PrintWeek India 09 May The journey of corrugated boxes began in India since That was when there was "de-servation" on the size and capacity of box plants. Today, the corrugated box industry in India converts about 4. After the de-reservation the capacity output for a corrugation box plant, more than automatic corrugation lines have been set up in India.

And there are more than semi automatic lines litho lam type. In most cases, Patel said, the boxes have case sealing using hot-melt gluing systems which tend to increase the overall rigidity of three ply single wall boxes and contributes to better in-transit performance. It protects the content against damage and against pilferage. It promotes the brand and allows productive packing.

Today, the definition of a good box is changing. A good box must enable productive packaging. This means, it should permit the following: case dispensing, case forming, auto case filling, case closure, batch identification inkjet or dot matrix printing. The other thing a good box must do, is reduce the typical box defects that disrupt smooth operations on an automatic packing line.

Effect on automatic line: This causes, case extraction failure; forming failure; filling failure; closing failure — hotmelt joints. Effect on automatic line: formation failure and jamming closure failure spring back. Effect on automatic line: extraction failure, formation failure and closure-hotmelt joint failure. The corrugated box has to not only protect its content but also has to ensure non-stop, snag-free running of the packing line.

In India, each and every corrugated box is a potential failure point and the tolerance for defects is very low. During the production of corrugated board and in-process handling the associated defects are: board warp flap and panel warps, wash-boarding and flap crease defects and ghost creases. The Cause: improper design and adjustment of stacker, manual handling of boards. The Cause: inappropriate ratio of glue application to paper gsm, lack of tension on liner papers. The Cause: improper creasing pressure at printer-slotter, improper setting and alignment of folder beams at flexo folder gluer FFG.

The Cause: improper creasing pressure at printer slotter, improper setting of squaring device at FFG. The corrugated box vendor has to upgrade his board and box making capabilities to meet the emerging requirements. Simultaneously, the packing line machinery manufacturers need to design and manufacture machines that are cost effective plus highly reliable given the likely increase in demand for automated packing lines.

There are many ways you could measure a corrugated box. Here are helpful guidelines to accurately communicate your requirements for determining the right dimensions of your boxes.

Use this info to work with case packing your boxes, and for handling your boxes with case formers, case tapers, and palletizers. Corrugated case dimensions are stated in the order of length, width, and depth or height L x W x Hreferring to the opening of an assembled box. Usually, the length is the longer of the two sides, and the width is the shortest.

The height or depth if the box is on its side is the distance between the opening and the opposite panel. When ordering or constructing a corrugated box, inside dimensions ID are used for measuring because the corrugated board thickness vary. A box constructed of C flute will have different outer dimensions than a box made from E flute material.

When measuring the inside of an existing box, measure from the center of the score fold line. When determining the right equipment to erect, form, tape, or glue your corrugated case, outer dimensions OD are considered.

Outer dimensions are also used for shipping in general and pallet configuration purposes. Indicate that the measurements are outer dimensions, for example: Please contact Pro Pac or call for your corrugated shipping cases.

Please fill in the required fields. Ready to Expand?In the beginning, there were kraft and white boxes with flexographic printing.

Then, in the s, the growing influence of big-box retailers forever changed corrugated converting. Instead of hiring sales people, big-box retailers demanded that the corrugated box stand out with a sleek, high-quality graphic that attracted attention and provided sales information to customers. As a result, litho-laminated packaging emerged as a major player in the corrugated industry.

For sheet plants, transitioning to litholamination presents opportunities to get into new markets, but it also comes with a few sticky challenges. The process of laminating gluing a printed litho-label to double-face corrugated board and then diecutting it can result in cracking on scores during the converting process. And if not applied properly, litholabels can bubble and not lay flat on the board.

By taking some relatively easy steps, these problems can be avoided, keeping customers, sales forces and production departments happy; and projects on schedule and most importantly, on budget. There are many potential causes for cracking on scores after a litho-labeled corrugated box is die cut.

But one of the primary reasons is also the one most overlooked: glue. The most common mistake is using dextrin glue which crystallizes when dried putting additional pressure on the back of the litholabel which leads to score cracking. One solution is to use resin glue. Unlike dextrin, resin glue dries as a pliable film and this reduces the pressure on paper when the score is folded.

However, compared to dextrin, resin glue is twice the cost per pound, and it attacks rubber which increases maintenance on laminators. Like resin, hybrid glue dries as a soft, pliable film; and like dextrin, hybrids are gentle on rubber. There are glue suppliers that have formulated hybrids specifically for litholamination. The cost issue becomes immaterial when you do the math. Do you know how many pounds of glue you use per thousand square feet MSF?

Few companies weigh the glue tote before and after running a job, and then calculate the MSF through the laminator to determine their usage.

In fact, many companies allow laminator operators to use whatever amount of glue they feel is appropriate. Monitoring and controlling the spread rate of glue is vital and should be a part of your production methods. After months of trial and error, they consulted with a glue vendor. While score cracking can be caused by other issues, such as increased recycle content and low-moisture content of the litho-label, glue is the one component that is easy to control both from the type you purchase to the amount you apply.

The cause relates to the affect of liquid on paper fibers.

How to Measure a Corrugated Box

After liquid dries, the fiber size decreases, but remains larger than its original size. Think of spilled coffee on paper. If heavy ink areas are surrounded by areas with lighter ink coverage, such as a white border around the edge of the sheet, the fiber growth is manifested by a hump or bubble causing the paper to lift off the surface of the corrugated board after the application of glue.

Similar to flexographic inks, lithographic inks are transparent. In areas with large areas of dark colors the total ink coverage can be percent just shy of three hits.Just like corrugated box styles, printed custom corrugated boxes can be manufactured using different strengths of corrugated paper. Some questions to ask yourself which strength of corrugated paper is best for your application would include but are not limited to the following: How much will the contents weigh in my custom printed corrugated box?

What type of shipping environment will my custom printed corrugated box be traveling in? Will any other corrugated boxes be placed on top of my custom printed corrugated box? How fragile are my contents when placing them inside my custom printed corrugated box?

Basically, there are two types of corrugated paper — ECT and Mullen. The strength of ECT corrugated paper is directly related to the compression strength of both the liners and medium. In other words, how much weight can the corrugated box withstand before collapsing? ECT is typically measured in pounds per square inch for stacking strength.

ECT corrugated paper is usually less expensive than Mullen corrugated paper. Mullen paper has a higher concentration of virgin material than ECT. Virgin material typically comes from new wood IE: Logs, wood chips, etc. Mullen will still have some recycled content; however, the amount of recycled content in Mullen paper will be much less than ECT paper. Mullen corrugated paper is generally more expensive than ECT corrugated paper.

When comparing 32 ECT corrugated paper to lb. Mullen corrugated paper, there are two very interesting details. We also found that approximately 40lbs of product could go into a custom printed corrugated box made from lb.
