Different types of Poly Bag Used in Garments Industry

Poly bag also known as polythene bags. It is a common and one of the most important materials in readymade garments sector. Poly bag is a plastic packet, which is used to contain garments in order to keeping that garments intact and dust, dirt or moisture free.

There are different types of material are used to produce poly bag such as PP, LD, HD, LLDP, LDPE, OPP and VINYL etc. where, PP, LD, VINYL, LDPE & VINYL mainly used for special purposes. It should be noted that, in the past, PP and LD poly bags used for garments packing but now buyer prefers LLDP, LDPE for environmental friendly issues.

Garments are poly packed by workers

The main reason for choosing LLDP, LDPE is that, both are recyclable items, where others cannot be recycled. One more thing should be noted that, LDPE is little expensive than LLDP. At present, some buyer suggests to use both items proportionally in producing poly bag. Because, mixture of both item helps to transparent poly bag.

There are different types of poly bag used in garments finishing, which are mentioned in the below:

1.       Poly bags with flap,

2.       Poly bag with button,

3.       Adhesive poly or self-sealing bags,

4.       Lip and gazette bags,

5.       Zip lock ploy,

6.       Slider zip lock poly,

7.       Poly tubing / Heat Sealed,

8.       Plain poly bags,

9.       Hanger bags.

Poly Bag Thickness:

Normally, we can count poly bag thickness by using three different ways. Those are-

1.       Mil,

2.       Microns,

3.       Gauge.

Mil:

Mil means the thickness is of 1/1000 of an inch. That means, 1mil= 1/1000 of an inch.

Microns:

Microns means the thickness is of 1/1000 of an mm. That means, 1microns= 1/1000 of an mm.

Gauge:

Microns means the thickness is of 1/100000 of an inch. That means, 1gauge= 1/100000 of an inch.

Relation between Mil, Microns and Gauge:

1 mil = 25 microns = 100 gauge

Among the above three, gauge is the most used system of counting poly bags thickness in the worldwide.

Sewing Thread Consumption of Garments

Approx. sewing thread consumption of different items

1	Basic t- shirt	125 Meter
2	Basic polo shirt	175 Meter
3	Tank top	50 Meter
4	Fleece/Sherpa jacket	250 Meter
5	Kids/girls dresses	300-450 Meter
6	basic long sleeve woven shirt	150 Meter

A Garments having 104 inches 4 Threads Over lock stitches, 52 inches 5 Thread Flat lock stitches, 20 inches 1 Needle Chain stitches, 15 inches Single Needle Plain Machine stitches, GSM is normal, find out its thread consumption in meters? 

Answer: {(104 x 16.75) + (52 x 22.25) + (20 x 5) + (15 x 2.5) + 10%} / 39.37 = 77.76 Meters. (39.37 inches = 1 Meter) 

*** Suppose, we want to buy thread cones with 2000 meters thread, now figure out how many cones do we need to stitch 30000 pcs of garments, per garment’s thread consumption 77.76 meters? 

Answer: 77.76 x 30000 / 2000 = 1167 cones. 

How to calculate Consumption in Garments?

Knit fabrics are usually measured in kilogram whereas it is related to GSM as well. Knit fashion is now popular in the world market. Knit merchandising is not so easy thing whatever consumption is one of the key factors for knit merchandising. T-shirts, pull over, polo-shirt (long sleeve or short sleeve) are treated as knit top garments as well as trouser and pant are treated as knit bottom garments.

Consumption formula for any TOP knit Garments

 (Measurement in CM)

{(B.L + S.L. + Allowance) X (1/2 Chest + Sewing Allowance) X 2 X GSM X 12 ÷ (10000 X 1000)} +Wastage%   kg/dz   

Here,

1.   Body length of the garments in cm. Say it is - 73 cm

2. Sleeve length of the garments in cm. Say it is - 19.5 cm

3. Approximate sewing allowance at body hem, shoulder joint, sleeve hem & armhole joint (in cm). Say it is - 10 cm 

4. Chest width (1/2) in cm. Say it is - 52 cm

5. Approximate sewing allowance at both side seams (in cm). Say it is - 4 cm

6. Fabric GSM (finish). Say it is - 160 gsm

7. Approximate fabric wastage in various stages. Say it is - 10%
8. 10000 means cm is converted into meter

        9. 1000  means gram is converted into kg

Rules: 

= {(B/length + S/length + Sewing Allowance) X (1/2 Chest + Sewing Allowance)}X 2 X GSM X 12 / 10000000 + Wastage
= {(73 + 19.5 + 10) X (52 + 4)} X 2 X 160 X 12 / 10000000 + 10%
= (102.5 X 56) X 2 X 160 X 12 / 10000000 + 10%
= 5740 X 2 X 160 X 12 /10000000 +10%
= 22041600 / 10000000 + 10%
= 2.20416 + 10 %
= 2.424576
= 2.43 kg per dozen. (Consumption)

(Measurement in INCH)

(B.L + S.L. + Allowance) X (1/2 Chest + Allowance) X 2 X GSM X 12 ÷ (1550X 1000) +Wastage%    kg/dz   

Here, 

B.L - Body Length

S.L - Sleeve Length

Allowance - Allowance would have considered for both B.L and S.L

1550 means inch is converted into meter (1 inch = 39.37" where inch square will be 39.37"X39.37")

1000 means gram is converted into kg
