Poly bag costing for clothes is some other vital mission for garb merchandisers. It additionally continues an impact on the complete pricing of orders. Poly bags, oftentimes acknowledged as polythene bags, have a range of makes use of in many industries. This is a plastic packet (pouch) used to comprise clothes destined for export or to merchandise so that apparels stay intact and they may want to now not reap dust, dirt, or moisture. In specific to garments, the fabric used may additionally be of LDPE, PP, or VINYL. In these LDPE can be recyclable, and others can't be recycled.
Most used poly luggage in clothes industries are PP (polypropylene) poly bags, PE (polyethylene) & LDPE (low-density polyethylene), HDPE (high-density polyethylene), etc. Basically, there’re three one of a kind methods to measure poly luggage 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 = one hundred gauge.Note: Gauge is the most used machine of counting poly bags’ thickness worldwide.
Example-1:
A poly bag having size of 30 inches, flap three inches, width sixteen inches, poly thickness one hundred fifty gauge. Now locate out the weight of one thousand pcs poly bags?
Answer: {(30 + 1.5) x sixteen x one hundred fifty / 3300} = 22.91 KGs for one thousand pcs
Formula: KGs wanted for one thousand pcs poly luggage = {(length + half of flap) X width X gauge / 3300}
Now, if we desire to locate out the weight of 1 pcs poly bag, then we want to divide the effect via 1000.
Answer: 22.91 / a thousand = 0.023 KGs. (1 pcs poly bag weight)
Note: You see, I count number flap dimension in 1/2 (1.5 inches) throughout calculation due to the fact the flap is single layer & length, the width of a polybag is double layer.
Example-2:
An LDPE poly bag having 28” length, 3” flap, 14” width, one hundred forty gauge thickness with the self-adhesive facility, and if the fee of polymer is $.50 per lb. Let’s locate out the price of 1 laptop poly bag.
Solution:
So, weight of fabric = (28+3 X 14 X 140) / 3300
= 60760 / 3300
= 18.412 kg /1000 pics
To produce one thousand photographs of poly bag, want 18.41kg polymer.
Cost of Material = 18.412kg x $.50 per lb
= 18.41 x $1.1/Kg (as we comprehend 1 kg = 2.20 lb)
= $20.253 / one thousand pics.
= $0.020 (cost of 1pc poly bag)
Cost of Adhesive tape = 28” x $.002
= $.056
So, closing fee of 1 laptop poly bag will be = ($0.020 + $.056)
= $0.076
