Before You Buy an Automatic Packaging Machine: What Information Should You Provide to the Supplier?

Buying an automatic packaging machine is not simply about telling a supplier, “I need a machine for 500 g of coffee,” and asking for a quotation.

To recommend a suitable machine, a packaging equipment supplier usually needs to understand your product, packaging format, production target, factory conditions, and future plans.

The more complete your initial information is, the easier it is to compare different suppliers, avoid unsuitable machine configurations, and receive a quotation that actually matches your production needs.

Here is a practical checklist of the information you should prepare before contacting a packaging machine supplier.

1. What Product Are You Packing?

Start with the product itself.

Tell the supplier:

• Product name

• Powder, granule, liquid, paste, or solid

• Particle size, if applicable

• Bulk density

• Viscosity

• Flowability

• Stickiness

• Whether the product is fragile, oily, or dusty

• Product temperature during filling

For example, “coffee powder,” “rice,” and “tomato sauce” are very different products from a packaging machine's perspective.

Packaging equipment is selected based on product behavior, not only the product name.

If possible, provide a product photo or a short video showing how the product flows or is transferred. This can help the supplier understand the product characteristics more accurately.

2. What Pack Sizes Do You Need?

Next, define the target filling weight or volume.

For example:

• 50 g

• 100 g

• 250 g

• 500 g

• 1 kg

If you have several sizes, list the minimum, standard, and maximum pack sizes.

For example:

100 g / 250 g / 500 g / 1 kg

This is important because the required machine configuration may be different when one machine needs to handle a wide range of pack sizes.

Also consider your future products. If you currently produce 250 g packs but may add 1 kg packs later, tell the supplier from the beginning.

3. What Production Capacity Do You Need?

Don't just say “high speed.”

Give the supplier a specific target whenever possible:

• Bags per minute

• Bags per hour

• Tons per day

• Bottles per hour

For example:

Target output: 60 bags/minute

It is also useful to explain whether this is your current production requirement or future target.

A machine designed for today's production may not be the most practical choice if you expect demand to double in the next few years.

And remember:

Machine speed is not always the same as actual production line output.

The feeding, weighing, packaging, inspection, and downstream processes can all affect the final capacity.

4. What Type of Bag or Package Do You Need?

The supplier needs to know your packaging format.

For flexible packaging, this may include:

• Pillow bag

• Gusseted bag

• Three-side seal pouch

• Four-side seal pouch

• Premade pouch

• Stick pack

• Sachet

Also provide the bag dimensions if available:

• Bag width

• Bag length

• Film width

If you already have a finished package, send a photo, drawing, or sample dimensions.

A picture of the actual package can often prevent several rounds of misunderstanding.

5. What Packaging Material Will You Use?

If you already have packaging film, tell the supplier its material and structure.

For example:

• PE

• PP

• PET/PE

• Other laminated films

If you don't know the exact material, you can provide the film specification or material datasheet instead.

This matters because different films can behave differently during:

• Film feeding

• Forming

• Tracking

• Heat sealing

• High-speed operation

The packaging material is therefore not only a marketing or appearance decision—it can also affect machine performance.

6. What Filling or Weighing Accuracy Do You Need?

If you have a specific accuracy requirement, provide it.

For example:

Target weight: 500 g
Required accuracy: ±1%

If you don't know which dosing system is appropriate, simply tell the supplier your product, pack size, target speed, and accuracy requirement.

Depending on the product, the supplier may recommend:

• Auger filler

• Multihead weigher

• Volumetric cup filler

• Liquid pump

• Piston filler

The important thing is to give the supplier enough information to select the dosing principle rather than choosing a machine based only on its name.

7. What Are Your Factory Conditions?

A machine also needs to fit your factory.

Provide basic information such as:

Electrical supply

• Voltage

• Phase

• Frequency

Compressed air

If pneumatic equipment is required, tell the supplier whether compressed air is available.

Available space

If possible, provide the approximate:

• Installation area

• Ceiling height

• Material flow direction

• Existing equipment location

A machine may be technically suitable for your product but still be unsuitable if it cannot be properly integrated into your production area.

8. What Equipment Comes Before and After the Packaging Machine?

This is particularly important for automatic production lines.

Tell the supplier what equipment you already have or plan to install.

Before packaging

• Hopper

• Z-type elevator

• Screw conveyor

• Vacuum feeder

• Product preparation equipment

• Other feeding systems

After packaging

• Checkweigher

• Metal detector

• X-ray inspection

• Labeling

• Cartoning

• Case packing

• Palletizing

For example, if you already have a conveyor and checkweigher, the supplier needs to know their specifications and connection height.

The packaging machine is only one part of the production line.

9. Are There Any Hygiene or Compliance Requirements?

For food, pharmaceutical, or other regulated products, tell your supplier about your requirements at the beginning.

Depending on your market and product, this may include:

• Food-grade construction

• Stainless steel requirements

• Cleaning requirements

• Washdown conditions

• Dust control

• CE or other market requirements

• Specific inspection or quality-control requirements

It's much easier to design the machine correctly when these requirements are known before the quotation stage.

10. What Are Your Future Plans?

This is one of the most useful pieces of information that buyers sometimes forget.

Tell the supplier if you plan to:

• Add more products

• Increase production capacity

• Introduce larger or smaller pack sizes

• Add another packaging line

• Automate currently manual processes

For example:

Current requirement: 250 g and 500 g
Future requirement: 1 kg
Current output: 40 bags/min
Expected future output: 70 bags/min

This information can help the supplier recommend a machine with a more practical operating range instead of designing only for today's requirements.

What If You Don't Know All the Technical Details?

You don't need to have every answer before contacting a packaging machine supplier.

At the initial stage, try to prepare at least:

1. Product

2. Pack size

3. Target production capacity

4. Bag type and dimensions

5. Packaging material, if known

6. Factory country and power supply

7. Existing upstream/downstream equipment

8. Future production plans

If some technical information is unavailable, simply tell the supplier.

For example:

“We are not sure which dosing system is suitable. Please recommend one based on our product and target capacity.”

A capable packaging equipment supplier should be able to help you identify the remaining technical requirements.

A Simple RFQ Checklist

Before sending an inquiry, you can prepare the following information:

Final Thoughts

A good packaging machine inquiry is not about providing as many technical terms as possible.

It is about giving the supplier a clear picture of your product, packaging requirements, production target, and factory situation.

With this information, the supplier can more effectively evaluate:

Product → Dosing → Packaging → Inspection → Conveying → End-of-line automation

Instead of simply asking, “How much is the machine?”, you can start a much more productive technical discussion and determine which machine configuration actually fits your production.
