When purchasing custom plastic bags, many buyers ask:
"What information do you need before providing a quotation?"
The price of custom plastic packaging bags depends on many factors, including bag type, material, size, thickness, printing, order quantity, and shipping terms.
To provide an accurate quotation, manufacturers usually need detailed product requirements from buyers.
Q1: What information should I provide for a custom plastic bag quotation?
To calculate an accurate price, please provide the following information:
Bag type
Bag size
Material requirement
Thickness
Printing design
Order quantity
Packaging requirements
Application
Certification requirements
Shipping terms
The more detailed the information you provide, the more accurate the quotation will be.

Q2: What types of plastic bags can you manufacture?
Plastic bag manufacturers can produce different types of packaging bags according to customer requirements, including:
Ziplock Bags
Stand Up Pouches
Flat Bags
Side Seal Bags
3 Side Seal Bags
T-Shirt Bags
Mailing Bags
Die Cut Bags
Garbage Bags
Vacuum Bags
Different bag structures require different production processes, which will affect the final price.
Q3: Why do you need the bag size before quoting?
Bag size directly affects material consumption and production cost.
The manufacturer normally needs:
Length
Width
Gusset size (if required)
For example:
400mm × 500mm + 50mm gusset
means:
Width: 400mm
Length: 500mm
Side gusset: 50mm
A larger bag requires more raw material, resulting in a higher price.
Q4: Which materials are available for custom plastic bags?
Common plastic packaging materials include:
| Material | Features | Applications |
|---|---|---|
| LDPE | Soft, flexible, waterproof | Mailing bags, packaging bags |
| HDPE | Strong and economical | Shopping bags, garbage bags |
| PP | Transparent and heat resistant | Food packaging |
| BOPP | High transparency and excellent printing | Snack packaging |
| CPP | Good flexibility | Composite packaging |
| PLA | Compostable and eco-friendly | Sustainable packaging |
The material selection depends on product requirements and application.
Q5: Does plastic bag thickness affect the price?
One of the main reasons is thickness.
Plastic bag thickness is usually measured by:
Micron
Mil
For example:
30 micron
50 micron
80 micron
A thicker bag uses more material and provides higher strength, so the production cost increases.
Q6: How does printing affect the quotation?
Yes.
Printing requirements directly affect the cost.
The quotation depends on:
Number of printing colors
Printing side
Printing area
Special printing effects
For example:
1 color printing
4 color printing
8 color printing
Generally, more colors require higher printing costs because of additional plates and production processes.
Q7: Why does order quantity affect the plastic bag price?
Plastic bag production includes some fixed costs, such as:
Printing plate cost
Machine setup cost
Material preparation cost
Production adjustment cost
When the order quantity increases, these costs are spread over more products.
Example:
| Quantity | Estimated Price |
|---|---|
| 10,000 pcs | Higher unit price |
| 50,000 pcs | Lower unit price |
| 100,000 pcs | More competitive price |
| 500,000 pcs | Best bulk price |
For large-volume orders, factories can provide better pricing.
Q8: What is included in FOB plastic bag pricing?
FOB (Free On Board) means the supplier is responsible for delivering goods to the agreed export port.
A typical FOB quotation includes:
✅ Plastic bag production cost
✅ Packaging cost
✅ Transportation from factory to port
✅ Export customs clearance
FOB quotation does not include:
❌ International ocean freight
❌ Insurance
❌ Destination port charges
Q9: Why are there different FOB prices?
Different FOB prices may be caused by:
1. Different loading ports
Example:
FOB Shanghai
FOB Ningbo
FOB Shenzhen
Different ports have different:
Domestic transportation costs
Port handling fees
Export service fees
2. Different order quantities
A quotation for:
100,000 pcs
will usually be cheaper than:
