How to Measure a Box

To get the most accurate estimate when ordering a retail packaging  folding carton box, use this as a guideline to give the correct measurements.

ALWAYS MEASURE THIS WAY:
1. Length (L) x 2. Width (W) x 3. Depth (D)

Which way is length?

1. LENGTH
Sit the package on its Tucks. Face the front of the package in front of you. Length of the face panel (usually the main graphic panel) is measured right to left, score to score of that panel only.

2. WIDTH
Sit the package on its Tucks. Face the front of the package in front of you. Length of the face panel (usually the main graphic panel) is measured right to left, score to score of that panel only.

Note:  The length and width are always meausred on the box openning  direction.

3. DEPTH (HEIGHT)
Depth of package is last. The “load” dimension of the product.

measure the box length width and depth

ISTA 1A Test for the Corrugated Shipping Cartons

ISTA 1A test is widely used to assured the carton box quality during the transportation. In DePrintedBox, we have a series of test to make sure of the box quality. However, the clients can also apply a ISTA 1A test for the printed box to be 100% sure the package is perfect for their needs. The test will be implemented by the certified institutes and be charged a certain fee to the clients.Below is a short introduction to the ISTA test.

1. What does ISTA refer to?

International Safe Transit Association (ISTA) is an organization focused on the specific concerns of transport packaging and is dedicated to develop and deliver standards packaging systems.

2. What is ISTA 1A test for the corrugated package?

ISTA 1A test is designed to make sure that the corrugated package can withstand the transport hazard. With the test properly applied, the ISTA procedure can provide the tangible benifit of

• Shortened carton development time and confidence in product launch
• Protection of products and profits with reduced damage and product loss
• Economically balanced distribution costs
• Customer satisfaction and continued business.

3. There are three sections: Overview, Testing and Report

Overview provides the general knowledge required before going into the testing laboratory and
Testing presents the specific instructions to do the testing in the laboratory and
Report indicates what data shall be recorded to submit a test report to ISTA.

4. Two systems of weights and measures are presented in ISTA test procedures.

They are the English system (Inch-Pound) and the international system SI (Metric). Inch-Pound units are shown first with Metric units in brackets, except in some tables where they are shown separately.

• Either system may be used as the unit of measure (standard units), but
• The standard units chosen shall be used consistently throughout the procedure.
• Units are converted to two significant figures and
• Not exact equivalents.

Paper Grammage(GSM), PT and Thickness Comparison and Conversion Table

Paperboard Thickness and Grammage Conversion Table

单铜,双铜,白卡,灰底白板纸张克重gsm, 厚度和pt对照转换表格

In China, the thickness of the paperboard is measured in milimeters, while point is used in USA, which is abbreviated to pt. The fomulas below can be used for the conversion of the 2 units.

1 inch =25.4mm = 1000 pt. 

1 pt = 0.0254mm

For example, 60pt=60*0.0254mm=1.524mm. The 60pt chipboard in USA refers to the 1.5mm greyboard in China, which is very ideal for the small rigid paper boxes. When you need a strong rigid box, 80pt chipboard can be used, which is 2mm thick greyboard in China.

– 标准厚度(mm)         – 标准厚度(mm)  
10PT 0.254                    11PT 0.279  
12PT 0.305                    13PT 0.330

Note: 1. The duplex board with grey back is also referred to as the while lined chipboard with greyback, clay coated new back(CCNB).

2. The duplex board with white back is also referred to as the white lined chipboard with white back.

3. The wouldfree paper is also referred to as the offset paper

4. The SBS C1S, C2S is also referred to ivory board or art paper in China. C1S means that the paper is coated on only one side of the paperboard. C2S means that both sides of the paperboard are coated. Ivory paperboard in China usually refers to the SBS C1S. Such papers are used to make the luxury printed paper boxes and cosmetic boxes.

5. The art paper is also called coated paper.
