About

The problem this site exists to fix

Search for almost any packaging specification and every result on the first page belongs to a company selling boxes, selling testing, or brokering freight. Those pages are not usually wrong. They are, however, written by a party with an interest in the answer, and they tend to stop exactly where the commercially useful part ends.

Look up the difference between an edge crush rating and a burst rating, for instance, and you will find a dozen explanations and a chart lining the two up column by column. What you will rarely find is the fact that the chart is a compliance mapping drawn from freight classification tables rather than a strength conversion, or that an accredited laboratory will tell you the two properties cannot be derived from one another at all.

That gap is the whole reason for this site.

What is covered

Four areas, and nothing else:

• Board and box specifications. Board grades and what they certify, flute profiles, single through triple wall construction, structural styles, dimensioning conventions, and the box maker’s certificate.
• Package testing and certification. Test protocols and what each one simulates, laboratory accreditation, retailer certification programs, and what a test report actually contains.
• Cushioning and protective materials. Cushion curves and fragility, foam grades, void fill, barrier packaging, and static protection.
• Palletization and freight. Pallet standards, unit load stability, dimensional weight, and freight classification.

What is deliberately not covered

A reference site is only useful if its edges are firm. These subjects are out of scope, permanently:

• Retail and primary packaging design, branding, and print production.
• Food contact safety, pharmaceutical packaging validation, and anything else where a packaging decision is a regulated health decision.
• Packaging machinery and warehouse operations.
• Vendor comparisons, supplier rankings, and buyer guides.

Several of those are subjects where the right answer depends on a regulator or a qualified engineer rather than on a published table. The rest would turn a narrow reference into a general logistics blog.

How the material is built

Articles are assembled from published test methods, carrier classification rules and primary industry documentation. Where a test method is discussed, it is named by its designation. Where a carrier requirement is described, the governing rule is identified. The reasoning is in the open so a reader can follow any claim back to its source and check it.

Some governing documents in this field sit behind paywalls or membership. Where a figure could not be confirmed against a primary source, the text says so rather than presenting an estimate as settled fact. The editorial policy sets out the full method.

Who this is for

Packaging buyers comparing quotes. Ecommerce sellers trying to understand why a carrier rejected a carton. Quality and operations staff investigating damage. Anyone holding a box with a stamp on the bottom panel and no clear sense of what it promises.

Independence

This site does not manufacture packaging, run a testing laboratory, broker freight, or take commission on packaging purchases. No company can pay to appear in an article or to have criticism removed. How the site is funded, and what that funding does not buy, is set out in the affiliate disclosure.

Errors

They get fixed, and the fix is recorded rather than quietly absorbed. See the corrections policy, or write to [email protected].
