METHOD OF ANALYSIS

Description: 

One-end open transparent LDPE bag.

Dimension: 

• Instrument Required: Measuring scale
• Width: Take the measuring scale and measure the width, it should be 815 mm ± 10 mm (805 mm - 825 mm)
• Height: Place the LDPE bag on the plane surface & measure height, it should be 1015 mm ± 10 mm (1005 mm - 1025 mm)

Weight:

Take at least 10 empty bags and check their weight individually on the calibrated balance. Finally, calculate the average weight of the bags as follows.

Calculation: if n1 is the weight of the first LDPE bags in kg, n2 is the weight of the second LDPE bag in kg and so on, then

It should be 0.12 k ± 0.01 kg [0.11 k - 0.13 kg]

GSM: 

Instrument Required: Cutter, Measuring scale, Analytical weighing balance

Cut the LDPE bag of size 0.1 m x 0.1 m [ 10c㎡ ] [ length x breadth ]

Take the weight of the cut piece on an analytical weighing balance.

Calculate the GSM value as follows:

Limit: 100 g/㎡ ± 10 g/㎡ (90 g/㎡- 110 g/㎡)
