By the S.Q & Sons team, Karachi ·

To get an accurate poly bag quote, send: bag type, width × length (plus gusset), thickness in micron, material, color, print details and quantity. If you don't know the thickness or material, describe what goes in the bag and its weight, and the manufacturer can recommend them.

Bag length excludes any flap or lip. For a gusseted bag, send us the product size and we can advise on the gusset.

Custom poly bags are made to order, so the price depends on exactly what you ask for. A complete request can be priced in one reply; an incomplete one turns into several rounds of questions. This checklist covers everything a manufacturer needs.

1. Choose the bag type

Start with how the bag will be used: a plain or printed bag, a courier flyer, a garbage bag, a heavy-duty industrial bag, or film such as stretch roll or shrink wrap. Each has its own details to specify.

2. Measure the size

  • Width: across the opening, measured with the bag flat.
  • Length: from the opening to the bottom seal. For a bag with a flap, give the flap length separately.
  • Gusset: for bags with side or bottom gussets, give the gusset depth when opened out.
  • Allow for depth: a thick product takes up width and length. As a rule of thumb, add the product's depth to both its width and its length, plus a little extra so it slides in easily.

Sizes can be given in inches or centimeters; just say which.

3. Choose a thickness

Thickness is usually given in micron. If your current supplier uses gauge or mil, convert it with our thickness converter. The right thickness depends on the weight and edges of the product and how the bag is handled; if you're unsure, describe the product and let the manufacturer recommend one.

4. Choose the material

Most poly bags are LDPE, LLDPE, HDPE or a blend. LDPE is soft and clear, LLDPE adds strength and puncture resistance, and HDPE is stiff and strong at low thickness. See LDPE vs HDPE vs LLDPE for a full comparison.

5. Decide on color and print

  • Film color: clear, natural, white or a color. See colored and transparent bags.
  • Print: the number of print colors, and whether you need printing on one side or both.
  • Artwork: send your logo or design, ideally as a vector file (AI, EPS or PDF). See custom printed bags.

6. Give the quantity

State the number of bags, or the weight in kilograms if you already buy by weight. If you order regularly, mention how often; it helps with production planning.

7. Send your request

Put everything in one message: use our quote form (you can attach artwork there), or send the same details on WhatsApp or by email from our contact page.

Frequently asked questions

How do I measure the size of a poly bag?

Measure the bag flat. Width is the measurement across the opening, and length runs from the opening to the bottom seal. For a gusseted bag, also give the gusset depth when it is opened out. Leave allowance for the product's depth: a bag for a thick item needs to be wider and longer than the item's face.

What information do I need to get a poly bag quote?

Bag type, width and length (plus gusset), thickness, material if you know it, color, printing (number of colors and sides), and quantity. If you are not sure about thickness or material, tell us what you are packing and its weight.

What file format should my logo be for bag printing?

A vector file such as AI, EPS or PDF gives the sharpest print. A high-resolution image can be used as a starting point.
