How do you calculate bursting strength of corrugated box?

Last Updated: 16th April, 2021

The diaphragm is expanded using hydraulics and as thediaphragm expands, the corrugated board bursts underpressure. We measure the bursting strength inKilograms per square centimetre. The Bursting factor isgiven as a thousand times the bursting strength, divided bythe grammage of the board.

Furthermore, how is bursting strength measured?

Bursting strength is measured by means ofa Mullen tester. The test specimen, held between annular clamps, issubjected to an increasing pressure by a rubber diaphragm, which isexpanded by hydraulic pressure at a controlled rate, until the testspecimen ruptures.

Likewise, how much weight can a corrugated box hold? Depending on the size and quality, a single wallcardboard box is likely to hold between 30-80 lbs. Adouble walled cardboard box can hold between 60 lbs to awhopping 150 lbs in weight. The corrugated cardboardadds miracles to its quality, with the center fluted sheet forminga support to two external sheets.

Also question is, what is bursting factor of corrugated box?

The bursting factor of the paper is burstingstrength divided by the basic weight of paper in grams persquare meter. The bursting strength tells you the amount ofpressure the paper can tolerate before it bursts orruptures. In case of corrugated boxes, the corrugatedor fluted paper improves the durability.

How much weight can a 32 ECT box hold?

An equivalent 44 ECT rated single wall cartonwill weigh on average 149 pounds per 1000 square feet ofmaterial used.

What does 200 lb test mean?

200 lb. test refers to bursting strength,while 32 ECT refers to stacking strength. Boxes that meet 200lb. test will also exceed 32 ECT stacking strength.Greater bursting strength means fewer crushed and damagedboxes during shipping.

What is the difference between bursting strength and bursting factor?

The bursting factor of a paper is calculated bydividing the bursting strength of paper by the weight of thepaper. The result of the bursting factor is expressed ingrams per sq. meter. On other hand, the bursting strength isthe amount of pressure that the paper can bear easily before itruptures.

How do you find the burst factor of paper?

Burst factor = Bursting strength (gf/cm2)/ Grammage (gf/m2)
To determine the bursting strength of thematerial, first, you need to have Bursting Strength Tester.This machine determines the strength of the material which isfurther used to determine the bursting factor andbursting index.
