Before starting the poly bag consumption calculation, a garments merchandiser should confirm the following information:

  1. Length of poly bag in inch,
  2. Poly bag width in inch,
  3. Thickness of poly bag in gauge,
  4. ½ flap of poly bag (Flap is single layer and width of poly bag is double layer),
  5. of print on the poly bag (Print can be any types of logo, text, warning etc.).

Now, by using the below formula, we can easily calculate the poly bag consumption in apparel industry.

Poly bag consumption (for 1000pcs in kg),

Now, one example is enough to remove all kinds of confusions from the above discussion.


Suppose, for a garments export order (10,000pcs), the buyer “H&M” suggests the below information about the poly bag.

Length of poly bag- 30”,
Poly bag width- 25”,
Thickness of poly bag- 160 gauge,
½ flap of poly bag- 3”,

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


Poly bag consumption (for 1000pcs in kg),

= 40 kg per 1000pcs poly bag.

So, for 1000pcs poly bag, LDPE polymer needed 40kg.


For 10,000pcs poly bag, LDPE polymer needed= (40 × 10) = 400kg.
