Poly Bags Consumption & Costing in the Apparel Industry

Poly bags play a vital role in the apparel industry for packaging and storing garments. These bags are widely used in the industry due to their durability, flexibility, and low cost. In this blog, we will discuss the consumption and costing of poly bags in the apparel industry.

Most used poly bags in garments industries are PP (polypropylene) poly bags, PE (polyethylene) & LDPE (low density polyethylene), HDPE (high density polyethylene) etc. Basically there’re three different ways to measure poly bags thickness. These are:

(1) Mil (1 mil = 1/1000 of an inch)

(2) Microns (1 microns = 1/1000 of a mm)

(3) Gauge (1 gauge = 1/100000 of an inch)

Conversion, 1 mil = 25 microns = 100 gauge.

Note: Gauge is the most used system of counting poly bags’ thickness worldwide.

A poly bags having length 30 inches, flap 3 inches, width 16 inches, poly thickness 150 gauge. Now find out weight of 1000 pcs poly bags? Answer: {(30 + 1.5) x 16 x 150 / 3300} = 22.91 KGs for 1000 pcs

Formula: KGs needed for 1000 pcs poly bags = {(length + half flap) X width X gauge / 3300}

Now, if we want to find out weight of 1 pcs poly bag, then we need divide the outcome with 1000.

Answer: 22.91 / 1000 = 0.023 KGs. (1 pcs poly bag weight)

Note: You see, I count flap measurement in half (1.5 inches) during calculation because flap is single layer. And length, width of a poly bag is double layer.

Now the question is 1 lbs. polymer price is 0.40 USD, find out cost of 22.91 KGs polymer?Answer: 22.91 x 2.2 x 0.40 = 20.16 USD. (1 KG = 2.2 lbs.)

A poly bags having length 30 inches, flap 3 inches, width 16 inches, poly thickness 150 gauge. 1 lbs. polymer price is BDT 40. Now find out cost of 1 pcs poly bag? Answer: {(30 + 1.5) x 16 x 150 / 3300 / 1000 x 2.2 x 40} = 2.01 BDT. (Bangladeshi Taka).

In conclusion, the consumption and costing of poly bags in the apparel industry depend on various factors such as the type of poly bag, its thickness, size, and the price of the polymer used to make them. By using the formulas mentioned above, we can calculate the weight and cost of poly bags accurately, which can help apparel manufacturers to make informed decisions and optimize their production costs.
