Introduction:
Poly bags, commonly known as polythene bags, have a variety of uses in many industries. But it has great use in garments industry. It is used to contain garments destined for export or to merchandise so that apparels remain intact and they could not obtain dust, dirt or moisture. Poly bag consumption is an important matter in apparel merchandising. Because it also keeps effect on total pricing of order. In previous article we have discussed on costing of poly bag for merchandisers.
 Poly bag in garment industry
Consumption of Poly Bag:
For consumption of poly bag, apparel merchandiser should know the following information.
1. Poly bag length in inch
2. Poly bag width in inch
3. Thickness of poly bag in gauge,
4. ½ flap of poly bag
5. Print on the poly bag
Using formula, we can easily calculate the poly bag consumption in garment industry.

Poly bag consumption (for 1000pcs in kg),

(Poly bag length + ½ Flap) x Poly bag width x Thickness of poly bag
= ……………………………….…………………………………………..……
3300

Note: 3300 is a constant number for 1000 pcs

For clearing this formula, I’m giving an example. I think it will be helpful to understand this formula.

Example:
Suppose, for a garments export order (100,000pcs), the buyer “GAP” suggests the below information about the poly bag.

Length of poly bag- 40”,
Poly bag width- 30”,
Thickness of poly bag- 170 gauge,
½ flap of poly bag- 3”,

Now you have to calculate the poly bag consumption for the above order.

Solution:

Poly bag consumption (for 1000pcs in kg),

(Poly bag length + ½ Flap) x Poly bag width x Thickness of poly bag
= ……………………………….……………………………………………………
3300

(40 + 3) x 30 x 170
= ……………………………
3300

43 x 30 x 170
= ………………….
3300

219300
= ……………
3300

= 66.45

66.45 kg per 1000pcs poly bag.

So, for 1000pcs poly bag, LDPE polymer needed 66.45kg.

For 100,000pcs poly bag, LDPE polymer needed = (66.45 × 100) = 6645kg.
