Machine Wise Sewing Thread Consumption PER Inch

From this post you will get information regarding the sewing thread consumption depending on type of Machine :

Machine Name   Classification    Require thread/inch
Plain Machine, 
       1 Needle,                   2.5"  
Plain Machine         2 Needle                     5"
Over lock               3 Thread                  13.25"
Over lock               4 Thread                  16.75"
Over lock               5 Thread                  18.75"
Flat lock                 3 Thread                  16.75"
Flat lock                 5 Thread                  22.25"
     
Bar tack stitching                          7" Generally P/Operation

Button hole stitching                     7" Generally Per Hole

Button Attaching (2 hole)                 3" Per button
Feed of the ARM                           7" For one needle
Kanchai Stitching                          7" For one needle
Back Tape Stitching                      7" For one needle

After this you must include another 25% sewing thread before place the work order.
COST OF MAKING (CM) 


= {(Monthly total expenditure of the following factory / 26) / (Qty of running Machine of your factory of the following month) X (Number of machine to complete the layout)} / [{(Production capacity per hr from the existing layout,excluding alter & reject) X 8}] X 12 / (Dollar conversion rate)

= [{(50,00,000 / 26) / ( 100 ) X (25)} / {(200) X 8}] X 12 / 74


= [{192307.7 / (100) X (25) } / 1600] X 12 / 74 


= (48,076.9 / 1600) X 12 / 74


= 30.048 X 12 / 74


= 360.58 / 74


= $4.873 / dozen (this is the making cost (12 pcs) of the following items) 


However, normally at present (after starting the new salary scale)in Bangladesh we calculate the CM of any item consider the overhead sewing machine cost 1200 tk to 1400 tk/day that means $16.216 to $18.92/per day. 

The above is for a non-compliance factory. For the a compliance factory the per day machine cost will be 1800 tk to 2100 tk ( $24.32 to $28.37)



SO, if the an item produces 1600 PCs per day using 25 machines, then the CM will be 

= Overhead machine cost X require machine 
/ produce quantity X 12 / $74

= 1400 X 25 / 1600 X 12 / 74


= $3.547/DOZ 
Clarification of poly bag.

Details Clarification of poly bag.

Normally we used various kind of bag for pack the goods. Poly bag is the most common and important  item of them.  Normally we bought various kind / type of poly bag from the market. Most of the product are   packed with poly bag.

Mainly in apparel sector poly bag is a very common item. We packed the garments with the poly bag before insert in a carton for shipment. Sometimes we use one poly for one garment, we called it single poly. Sometimes we insert several single poly in a big poly we called it “blister poly.

Considering the material there is several classification in these Poly. Please find below the main classifications poly with all the details.


PE  (Polyethylene) 
A lightweight thermoplastic used especially in packaging. It is tough, flexible and chemical resistant characteristics. 


PP (Polypropylene)
Polypropylene has excellent chemical resistance is strong and has the lowest density of the plastics used in packaging. It is stiffer and clearer than polyethylene and has excellent
resistance to water, salt and acid solutions and, when manufactured with virgin resin, polypropylene (PP) meets FDA requirements for food applications. Polypropylene (PP) is exceptionally suited to maximize visual appeal of food and display products. Any product that needs an outstanding professional appearance can benefit from polypropylene (PP) packaging.
 


LDPE = Low Density Polyethylene
Low Density Polyethylene is the most commonly used material for flexible packaging because it is tough, transparent and electrically stable.  Low Density Polyethylene (LDPE) also has a low melting point, which is required for heat sealing applications. When low density polyethylene bags (LDPE) are made with virgin (no additives) polyethylene resin, they meet FDA standards for use with food products. 


LLDPE = Linear Low Density Polyethylene
A given thickness of Linear Low Density Polyethylene (LLDPE) is significantly stronger than the same thickness of Low Density Polyethylene (LDPE). Therefore, Linear Low Density Polyethylene (LLDPE) can be thinner and lighter and perform the same job as LDPE.  These bags are bottom sealed for added strength.  Linear Low Density Polyethylene (LLDPE) also has a low melting point, which is required for heat sealing applications.


HDPE = High Density Polyethylene:
High Density Polyethylene is used because of its excellent strength and significantly light weight.  It has excellent protection capability and it is used in grocery and other retail segments extensively, while also suitable for a myriad of other uses. 


Nylon Laminated Polyethylene 
Nylon Laminated Polyethylene Vacuum packaging is the process of removing the air from within an impermeable plastic package and sealing food items inside to maintain flavor, freshness and color.  Some forms of harmful bacteria thrive in the presence of oxygen.  A Nylon film is incorporated into vacuum bags to prevent oxygen from returning to the bag after the extraction process, and prevents bacteria from spoiling the   contents.  Nylon vacuum bags can be used to preserve many different types of food, including beef, lamb, chicken, fish and cheese.
Calculate the price of Polybag

To calculate the price of a poly bag you need the
following 07 (Seven) information at first, as listed
below:

i. Poly bag length in Inch.

ii. 1/2 length of the flap of Polybag (Here we take 1/2 length because the flap is single).

iii. Poly bag width in Iinch.

iv. Thickness of the poly bag in mm.

v. Number of print on the poly bag (Here print means the logo, size, warning etc.)

vi. Adhesive length in cm. Normally poly width and adhesive length will be same. 

vii. Polymer rate per pound (lbs) in bd tk of the following poly bag.It may PE or PP or Ldpe etc. 

At present market polymer (dana) rate is 80 tk (It is PP quality).  
What is Merchandising ?


The Merchandising is known to the persons specially involved in garments trade.   
The term merchandising has been derived from the Merchandise. Merchandise means goods
that are bought & sold.



Merchandising is the methods, practices, and operations used to promote and sustain certain
categories of commercial activity. In the broadest sense, merchandising is any practice which
contributes to the sale of products to a retail consumer. At a retail in-store level, merchandising
refers to the variety of products available for sale and the display of those products in such a way
 that it stimulates interest and entices customers to make a purchase.
