Poly bag costing:

Poly bag costing is another important task for apparel merchandisers. It also keeps effect on total pricing of order.

Poly bags, commonly known as polythene bags, have a variety of uses in many industries. This is a plastic packet (pouch) used to contain garments destined for export or to merchandise so that apparels remain intact and they could not obtain dust, dirt or moisture. In particular to garments, the material used may be of LDPE, PP or VINYL. In these LDPE can be recyclable, and others cannot be recycled.

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.

  • Mil (1 mil = 1/1000 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.

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 & length, width of a poly bag is double layer.

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 lb. Let’s find out cost of 1 pc poly bag.

So, weight of material = (28+3 X 14 X 140) / 3300

= 60760 / 3300
= 18.412 kg /1000 pics

To produce 1000 pics of poly bag, need 18.41kg polimer.

Cost of Material = 18.412kg x $.50 per lb

= 18.41 x $1.1/Kg (as we know 1 kg = 2.20 lb)
= $20.253 / 1000 pics.
= $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
