Best Techniques to Test the Quality of Corrugated Boxes (Part 3)

Corrugated boxes come with multiple properties such as compression, crushing, scuffing, thickness and many more. These properties define the quality of the corrugated boxes appropriately.

After discussing the renowned test procedures such as bursting strength tester, edge crush tester, cobb sizing tester and grammage test in the previous blogs, let's talk about a few more testing techniques that can help you measure the quality of the boxes. These are puncture resistance test, scuff resistance test, box compression test and chemical analysis in corrugated box testing.

• Puncture Resistance Tester

About : The test is about testing the tear resistance to penetration by sharp & solid objects
Purpose : To test cardboard strength and sturdiness during transportation

Puncture resistance test helps to examine whether the box can handle the impact made with a triangular or pyramid shaped weight. The test can be performed by a renowned testing machine known as Puncture resistance tester. The testing machine works on national and international test standards such as ISO 3036 and FEFCO 5.

• Scuff Resistance Test

About : Test the abrasion resistance strength of the printed boxes
Purpose : To ensure sustainability of printed text on cardboard box against wearing and rubbing

Printing is the most important part of packaging. With the different printing methods that are used on different types of packaging, it is important for the manufacturers to check how efficiently labels and prints can resist scuffing or abrasion. For this purpose, scuff resistance testing machines are introduced.

Also known as Sutherland Rub Test, the testing instrument is efficient on testing the paperboards, laminated prinitings, paper packaging, films and other printed materials. The testng instrument offers correct test results as they are designed keeping in mind the national and international standard test methods.

Alternatively, people also perform resistance to abrasion tests on corrugated boxes. These include continuous abrasion and manual wiping. Scuff resistance testers are widely used in pharmaceutical or medical industries because label legibility on the medicine packs and boxes is of utmost importance in these industries.

Another test procedure that you can perform to test the strength of corrugated boxes is,

• Box Compression Tester

About : Measuring compressive strength of a corrugated or similar type of packaging boxes.
Purpose : To measure the stacking strength of corrugated boxes when piled one above the other.

Also known as the container compression test, the Box compression tester, is the best way that helps you know how much load a corrugated box can tolerate on the top of it before it starts compressing. The compression test also gives you a good idea on how many boxes can be stacked one above the other without damaging the contents of the box which is placed on the bottom most layer.

Box compression tester is used in almost all the packaging manufacturing industries to disclose the maximum compressive strength of the boxes and which application it can suit. To perform the compression test, the boxes are placed in different angles and orientations .

Conclusion
The series of blogs on measuring the quality of the corrugated boxes and sheets, gives you a complete understanding of the testing procedures that you can perform to measure the quality of the boxes.
