1. Application Scope

This coffee stick pack cartoning line is suitable for:

• Instant coffee stick pack

• 3-in-1 coffee stick pack

• Black coffee stick pack

• Coffee premix powder stick pack

• Milk coffee powder stick pack

• Flavored coffee powder stick pack

• Beverage powder stick pack

• Private label coffee stick pack

• OEM coffee stick pack production

• Coffee stick pack box packing line

This solution is especially suitable for coffee brands, beverage powder manufacturers, OEM packing factories, and customers upgrading from manual counting and manual cartoning to automatic production.

2. Complete Line Workflow

Step 1: Coffee Powder Feeding

Coffee powder is transferred to the hopper of the multi-lane stick pack machine. Depending on product characteristics, the feeding system can be configured with:

• Screw conveyor

• Vacuum feeder

• Hopper level control

• Dust collection system

• Anti-bridging stirring device

For 3-in-1 coffee powder, the product usually contains coffee powder, sugar, creamer, flavoring powder, and other mixed ingredients. The material flow condition may be different from pure coffee powder, so the auger system and hopper structure need to be selected according to the actual product.

Step 2: Multi-Lane Stick Pack Forming

Roll film is divided into multiple lanes. Each lane forms one stick pack through a forming tube or forming collar.

The machine completes:

• Film unwinding

• Film splitting

• Date coding

• Vertical forming

• Back sealing

• Coffee powder filling

• Horizontal sealing

• Cutting

• Stick pack output

For coffee stick pack, back seal structure is commonly used because it gives a slim, long, retail-friendly package shape.

Step 3: Auger Filling

Coffee powder is usually packed by an auger filling system. The auger dosing system is suitable for powder products that require stable volume control and consistent filling accuracy.

For coffee powder, the filling system should consider:

• Powder flowability

• Bulk density

• Moisture absorption

• Dust level

• Granule size

• Product stickiness

• Filling weight

• Required accuracy

• Hopper stirring method

For instant coffee and 3-in-1 coffee powder, the machine can be equipped with a stirring system to improve material flow and reduce unstable dosing caused by bridging or powder accumulation.

Step 4: Stick Pack Counting and Arranging

After cutting, the stick packs enter the counting and arranging section. This part is important because it directly affects the accuracy and stability of automatic cartoning.

The system can count different quantities per box, such as:

• 10 sticks/box

• 20 sticks/box

• 25 sticks/box

• 30 sticks/box

• Customized quantity

For coffee retail packaging, 20 sticks/box and 25 sticks/box are very common formats. The counting system can be customized according to carton size, stick size, and required box layout.

Step 5: Automatic Cartoning

The cartoning machine automatically completes:

• Carton magazine storage

• Carton picking

• Carton opening

• Stick pack group feeding

• Product pushing into carton

• Carton flap folding

• Carton closing

• Finished box output

The cartoning section can be designed according to carton style, loading direction, stick quantity, and production speed.

3. Capacity Output Table

The following table is calculated based on the maximum cutting speed of 40 cuts/min.

Formula:

Stick packs per minute = Lane number × Cutting speed

For example:

8 lanes × 40 cuts/min = 320 stick packs/min

Output Based on 25 Sticks per Box

Output Based on Different Box Quantities

Note: The actual production speed depends on coffee powder characteristics, film material, stick size, carton size, counting method, box loading format, and inspection configuration. For stable long-term production, the recommended running speed is usually lower than the maximum mechanical speed.

4. Main Technical Parameters

5. Why Coffee Stick Pack Needs a Specialized Line

Coffee stick pack production is not only about filling powder into small bags. A stable coffee stick pack cartoning line must solve several practical production problems.

5.1 Coffee Powder Flowability

Pure coffee powder, instant coffee powder, and 3-in-1 coffee powder behave differently during filling. Some products flow smoothly, while others may bridge inside the hopper or create dust during high-speed filling.

The auger filler should be matched with:

• Proper screw diameter

• Suitable screw pitch

• Hopper stirring structure

• Anti-bridging design

• Dust control system

• Stable servo control

This helps improve filling accuracy and reduce weight fluctuation.

5.2 Moisture Protection

Coffee powder is sensitive to moisture and aroma loss. The stick pack sealing system must provide consistent sealing temperature, pressure, and time.

Important sealing factors include:

• Film material compatibility

• Vertical sealing stability

• Horizontal sealing strength

• Back seal alignment

• Cutting accuracy

• Seal wrinkle control

• Temperature zone control

A poor seal may cause leakage, powder contamination, reduced shelf life, or poor retail appearance.

5.3 High-Speed Cutting Stability

For 4–12 lane production, every cut produces multiple stick packs at the same time. At 40 cuts/min, a 12-lane machine can output up to 480 sticks/min.

At this speed, the machine must maintain:

• Accurate film pulling

• Stable registration mark tracking

• Clean cutting edge

• Consistent stick length

• Low film deviation

• Stable sealing pressure

• Smooth stick discharge

This is why mechanical structure, servo control, film tension control, and cutter precision are critical.

5.4 Counting Accuracy Before Cartoning

Manual counting is one of the biggest bottlenecks in coffee stick pack production. The automatic counting system helps reduce:

• Missing stick quantity

• Over-filled cartons

• Manual labor cost

• Secondary contamination

• Inconsistent retail box quality

For 25 sticks/box, even a small counting error can affect customer complaints and brand reliability. Therefore, counting and box loading accuracy are key factors in the complete line.
