**What is the Costing of Poly Bag Calculator?**

The Costing of Poly Bag Calculator is a tool used in the packaging industry to determine the total cost of manufacturing poly bags. It takes into account factors such as length, width, half flap, and gauge to calculate the cost per bag.

**The formula for the Costing of Poly Bag Calculator is:**

**Costing of poly bag={(length + half flap) X width X gauge }/3300**

**How to Use the Costing of Poly Bag Calculator?**

- Enter the length of the poly bag in inches.
- Input the width of the poly bag in inches.
- Provide the half flap measurement in inches.
- Enter the gauge of the poly bag.
- Click on the “Calculate” button to get the total cost of the poly bag.

The 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 are three different ways to measure poly bag thickness.

-Mil (1 mil = 1/100 DPE of an inch)

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

-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.

**Example-1:** 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?

**Solution: **

- Formula: KGs needed for 1000 pcs poly bags

= {(length + half flap) X width X gauge }/3300

={(30+ 1.5) x 16 x 150} / 3300

= 22.91 KGs for 1000 pcs

=0.023 KGs/Pcs poly

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

**Example-2:** A LDPE poly bag having 28″ length, 3″ flap, 14″ width, 140 gauge thickness with self adhesive facility and if cost of polymer is $.50 per lbs and Cost of Adhesive tape is $.002. Let’s find out cost of 1 pc poly bag.

**Solution:** So, weight of material = {(28+1.5) X 14 X 140/3300

= 60760/3300

= 18.412 kg/1000 pcs

To produce 1000 pcs of poly bag, need 18.41kg polymer.

**Cost of Material =**18.412kg x $.50 per lbs

= 18.412 x 2.20lbs x $0.50 (as we know 1 kg = 2.20 lbs)

= $20.253 / 1000 pcs.

= $0.020 (cost of 1pc poly bag)

**Cost of Adhesive tape** = 28″ x $.002

= $.056

**So, final cost of 1 pc poly bag will be** = ($0.020 + $.056)

= $0.076

**Example**

- A poly bags having length 30 inches, flap 3 inches, width 16 inches, Poly thickness 150 gauge. 1 lbs. polymer price is 40 taka. Now find out cost of 1 pcs poly bag?

- Answer: 2.01 taka

**Application of Costing of Poly Bag Calculator**

The Costing of Poly Bag Calculator is essential for manufacturers, suppliers, and distributors in the packaging industry. It helps in accurately estimating the production cost of poly bags, facilitating pricing decisions, cost optimization, and overall financial planning.
