2 Ways to Test the Strength of your Packaging

When it comes to the packaging design, the aesthetics are important in making a good first impression of your product to your customers. However, this is not just about whether you have a beautiful design or not. The quality of your packaging – including structural integrity, robustness, and endurance – all important factors in practical practitioners. After all, when you send your product to the customer, your package is likely to go through a variety of shipping conditions (and hard) before reaching your customers.

With that, there are various tests that you can do in your packaging box to measure the quality of your packaging. In this post, we will discuss 6 types of packaging tests that you can or suppliers you can do, along with the best practice for each.

1 – Packaging drop test

International standards originated from Isa (International Safe Transit Association), with the procedure for the decline in Ista 1A into an international standard received for the drop test.

When you come to do a drop test, the height where your shipping cardboard must be dropped from depending on the weight of the cardboard itself. This is the right height where your cardboard must be dropped from:

Height of cardboard weight loss

1-9kg (1-20LB) 76cm (30 “)

10-18kg (21-40lb) 61cm (24 “)

19-27kg (41-60lb) 46cm (18 “)

28-45kg (60-100lb) 30cm (12 “)

46-68kg (101-150LB) 20cm (8 “)

As you can see, lighter cardboard dropped from a height that is higher than a heavier cardboard. At any height above 76cm or 30 “, it becomes unrealistic to run a drop test to see whether your packaging will protect your product.

There are several standards that you can follow depending on the organization or operator for your delivery:

Ista: Procedure 3A: Delivery of Parcel Delivery System 150 LBS (70kg) or Less (UPS follows this standard)

ASTM: D7386-16 Standard Practice for Package Performance Testing for Single Parcel Delivery System 150 LBS or Less

Fedex: Ista-6-Fedex-A: Test for packaged products weighing up to 150 lbs.


Drop your shipping carton at an appropriate height 10 times from a different side. The following are examples of FedEx:

Effectively, you want to drop your shipping cardboard:

In the most fragile angle (e.g.

On the edges that come from a fragile angle (e.g. 3 drops)

On the 6 remaining sides

Your cardboard fails in the drop test if one of the following happens:

There was a significant damage to the shipping carton (completely destroyed, torn, or open)

There is significant damage to the inner packaging box (completely destroyed, really torn or damaged)

The product in the packaging box in defects, scratched, dented, or damaged and cannot be used

If you see some dent in the corner or edge of your shipping carton after the drop test, it’s normal. The purpose of the shipping carton is to protect what is in it, so every deformation in the shipping carton itself is good as long as the product in it is fully protected and not injured from the drop test.

Test the crush on the edge, or etc., measure how much the corner and edges of the corrugated material that can be taken until it is crushed. This custom bottle boxes is important because the angles and edges are mostly responsible for keeping the carton of sending upright and must be strong enough to hold all weight (eg piles of cartons) on it.

A piece of your corrugated material is entered upright between the engine and compressed at different pressures. ECT is measured in pound per inch and reported as an ECT ranking. Ranking 32 ECT is most commonly used as a base line for a single wall wavy box, and is suitable for most light to moderate products.
