**Introduction:**

Poly bag costing is an important matter in **garments merchandising**. All the **garment merchandisers** should know about it. Poly bag costing is not a tough task that we have normally seemed. As its importance in **readymade garments sector**, today I will present here the costing calculation method of poly bag.

**Poly Bag Costing Calculation Method in Garments Industry:**

At the starting of poly bag costing, a **garments merchandiser** should identify the below information:

- Poly bag length in inch,
- Poly bag width in inch,
- Poly bag thickness in gauge,
- ½ flap of poly bag (Flap is single layer and width of poly bag is double layer),
- Numbers of print on the poly bag (Print can be any types of logo, text, warning etc.),
- Rate of polymer per pounds (It can be PP, PE and LDPE etc.).

**Important Tips****

- The next duty is to calculate
**poly bag consumption**or calculate the amount of polymer needed to produce poly bag. - Then, by multiplying, poly bag consumption (total amount of polymer needed to produce poly bag) with polymer rate, a garment merchandiser can easily calculate poly bag costing in the apparel industry.

**Now, I will present an example here for poly bag costing. Hope all the confusions will be cleared.**

**Example:**

Suppose, the buyer “ZARA” suggests the below information about the poly bag of a garment export order.

Poly bag length – 28”,

Poly bag width- 24”,

Poly bag thickness – 160gauge,

½ flap of poly bag- 5”,

Rate of LDPE polymer- $0.40 per pound.

**Now, calculate the poly bag costing for the above order.**

**Solution:**

At first, we have to calculate poly consumption according to given data.

**Poly bag consumption (for 1000pcs in kg),**

= 38.4 kg per 1000pcs ply bag.

**So, for 1000pcs poly bag, LDPE polymer needed 38.4kg.**

And,

**For 1pc poly bag, LDPE polymer needed,**= (38.4/1000) kg= 0.04kg= (0.04 × 2.20) lbs= 0.08lbs

**So, cost of LDPE polymer for 1pc poly bag ($),**= LDPE polymer needed for 1pc poly bag × LDPE polymer cost per pound (lb)

= 0.08 × 0.40

= 0.03

So, cost of LDPE polymer or cost for 1pc poly bag is $0.03

And,

**Cost of 1000pcs poly bag,**= $(1000 × 0.03) = $30
