# Quick Answer: What Is GSM And BF?

## How do you convert GSM to Grams?

Divide the gsm by 33.906 – really that is all.

To determine gsm from oz/yd2 you do the reverse – multiple by 33.906.

If it helps, this is what the formulas are based upon: 1 oz = 28.3495231 grams (oz to grams converter).

## How do I check my bursting strength?

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

## What is GSM paper?

The term “GSM” stands for “grams per square meter.” For this standard, the weight of various types of paper is measured from a sample sheet cut to one square meter in size. … For example, paper with a weight of 55 gsm will be much, much lighter and thinner than paper weighing 400 gsm.

## How do I increase my boyfriend in Kraft paper?

Nowadays, maize starch is diluted and sprayed on the paper to increase its stiffness and Bursting Factor (B.F). The spraying of Maize starch on the Kraft paper results in a temporary increase of Bursting Factor (B.F.) and stiffness which decreases gradually with the absorption of atmospheric moisture.

## What is GSM in packing material?

GSM is an acronym for grams per square metre. It is a measurement used in the packaging industry to quantify the mass or density of a material, typically paper. It is essentially a measurement for the thickness of paper, and other associated material such as NWPP.

## How do I know GSM of paper?

Substance in gsm = (Weight of reel in kgs * 100000)/(Length of paper on meter * reel width in cms)Expressed in grams per square meter (g/m²), paper density is also known as grammage. … Expressed in terms of the mass (expressed as weight) per number of sheets, it is known as basis weight.

## What is burst factor?

Bursting Factor is that property which can be calculated after measuring the bursting strength of the boxes. The bursting factor can be calculated by dividing the bursting strength of a board by the basic weight of the paper. This property is expressed in grams per sq.

## How do you convert GSM to KG?

Convert weight into Kg dividing it by 1000….In the example:Fabric length is 1700 meters.Fabric width = 72 inch convert it into meters = (72 * 2.54) /100 =1.83 meters.Fabric GSM = 230 grams.

## What is the full from of GSM?

The Global System for Mobile Communications (GSM) is a standard developed by the European Telecommunications Standards Institute (ETSI) to describe the protocols for second-generation (2G) digital cellular networks used by mobile devices such as mobile phones and tablets.

## What is the meaning of BF in paper?

Bursting FactorBursting Strength (BS) & Bursting Factor (BF) of Paper as per ASTM Standards. … The pressure at which a film or sheet of paper will burst, is known as Burst Strength. Paper’s bursting strength is a vital strength property that is affected by many other properties of the sample, principally tensile strength and stretch.

## How do you calculate Paper boyfriend?

To Calculate the BF and BI, you first need to measure the burst strength of the packaging material. Once you get the burst value, using the below-mentioned calculation, BF and BI can be derived. To evaluate the effect of burst forces on a material, Bursting Strength Tester is used.

## How is BF of corrugated box calculated?

The diaphragm is expanded using hydraulics and as the diaphragm expands, the corrugated board bursts under pressure. We measure the bursting strength in Kilograms per square centimetre. The Bursting factor is given as a thousand times the bursting strength, divided by the grammage of the board.
