MSZP8-200 Automatic Rotary Premade Pouch Packing Machine

The MSZP8-200 Automatic Rotary Premade Pouch Packing Machine is designed to feed, open, fill, and seal compatible preformed pouches through a six- or eight-station rotary process.

It handles pouches from 90 to 200 mm wide and 100 to 350 mm long. Supported formats include stand-up pouches, flat pouches, zipper pouches, handle pouches, and compatible three-side- or four-side-seal bags.

The rotary pouch-handling platform can be matched with different dosing systems for liquids, sauces, powders, granules, snacks, and irregular solid products. The correct filling equipment must be selected according to the product’s flow characteristics, target weight, required accuracy, and cleaning requirements.

Rotary Premade Pouch Packaging Process

Pouch Feeding

Empty premade pouches are loaded into the bag magazine. The pouch-feeding mechanism transfers individual bags to the rotary grippers.

Bag thickness, surface friction, zipper position, and dimensional consistency affect feeding performance. Final production pouches should be tested before the bag magazine and gripping system are approved.

Pouch Gripping

The rotary grippers hold each pouch as it moves through the configured operating stations.

Gripper width must be adjusted when pouch dimensions change. The pouch should remain stable without being stretched, creased, or damaged.

Pouch Opening

The pouch-opening station separates the front and rear panels before filling. Opening performance depends on pouch flatness, film stiffness, static electricity, zipper structure, and the condition of the pouch mouth.

An unopened pouch should not proceed to filling. The availability of bag-opening detection and no-open-no-fill control should be confirmed in the ordered configuration.

Product Filling

The opened pouch moves to the filling station, where the selected dosing system dispenses the product.

The MSZP8-200 is the pouch-handling and sealing platform. Liquid, powder, granule, and solid products require different feeding and metering equipment.

Pouch Settling and Cleaning

Depending on the product, an additional station may be used for product settling, air removal, vibration, or cleaning material away from the sealing area.

Powder, sauce, oil, or product particles left on the pouch mouth can reduce seal consistency.

Heat Sealing

The filled pouch enters the sealing station. Sealing temperature, pressure, and dwell time must be matched to the pouch material and production speed.

A second sealing or cooling station may be configured where the pouch structure or application requires it.

Finished-Pouch Discharge

Sealed pouches are released from the rotary machine for inspection, metal detection, checkweighing, cartoning, case packing, or collection.

Product Dosing Systems

The MSZP8-200 can package different product categories when equipped with the appropriate dosing system. One filling system should not be assumed to handle every material.

Liquid Filling

Free-flowing liquids may require a pump, flowmeter, gravity, or other liquid-metering system selected according to:

• Product viscosity

• Filling volume

• Required accuracy

• Foaming tendency

• Product temperature

• Chemical compatibility

• Cleaning method

• Production speed

Typical applications may include soy sauce, vinegar, juice, rice wine, liquid detergent, peanut milk, and compatible hand-sanitizer products.

Liquids containing alcohol, solvents, corrosive ingredients, or suspended solids require a separate compatibility assessment.

Sauce and Paste Filling

Ketchup, jam, chili sauce, bean paste, seasoning sauce, peanut butter, and hot-pot base materials may require a piston or other positive-displacement filling system.

Sauce packaging should be evaluated for:

• Viscosity

• Product particles

• Filling temperature

• Oil separation

• Required hopper capacity

• Agitation requirements

• Heating requirements

• Nozzle diameter

• Cleaning access

Products containing large particles require a filling path that can pass the particles without crushing or blocking them.

Powder Filling

Powders such as coffee, milk powder, salt, seasoning powder, monosodium glutamate, and powdered drink mixes may be handled using a compatible auger or other powder-dosing system.

Powder behavior varies according to:

• Bulk density

• Flowability

• Dust level

• Moisture sensitivity

• Particle size

• Electrostatic behavior

• Required weight accuracy

Dust extraction or pouch-mouth cleaning may be required to keep powder away from the heat-seal area.

Granule and Solid Filling

Granules, nuts, seeds, candy, chocolate, dried fruit, chips, biscuits, and other solid products may require a volumetric cup, linear weigher, multihead weigher, counting system, or application-specific feeder.

Fragile products should be evaluated for drop height and handling impact. Irregular products should be tested to confirm that they enter the pouch without bridging or damaging the bag mouth.

Premade Pouch Compatibility

Pouch Dimensions

The published pouch range is:

• Width: 90–200 mm

• Length: 100–350 mm

Both dimensions must be considered together. A pouch within the stated width may still require evaluation if its length, gusset, zipper, handle, or opening structure differs from the standard configuration.

Supported Pouch Formats

The MSZP8-200 may handle compatible:

• Stand-up pouches

• Flat pouches

• Three-side-seal pouches

• Four-side-seal pouches

• Zipper pouches

• Handle pouches

Spouted pouches, unusually shaped bags, quad-seal bags, retort pouches, and pouches with special fitments require separate confirmation.

Pouch Materials

The original specifications reference composite film, PE, and PP pouch materials.

Successful heat sealing depends on the complete film structure rather than the outer material name alone. Customers should provide:

• Film-layer structure

• Total thickness

• Heat-seal layer

• Recommended sealing temperature

• Pouch supplier specifications

• Final production samples

Zipper Pouches

Zipper pouches require the mouth to be opened without damaging the zipper. Depending on the pouch design, a zipper-opening or zipper-closing mechanism may be needed.

The zipper position should remain consistent across the supplied pouch batch.

Filling and Sealing Control

Dosing Accuracy

Filling accuracy is determined mainly by the selected dosing system, product characteristics, target weight, and operating speed.

The original page does not publish an accuracy value. Customers should define the permitted tolerance before the filling system is selected.

Clean Seal Area

The seal area should remain free from product contamination. Sauce, oil, powder, crumbs, or sharp particles between the film layers can affect seal strength or appearance.

Depending on the product, the machine may require:

• Anti-drip filling nozzles

• Pouch-mouth spreading

• Dust extraction

• Seal-area cleaning

• Product settling

• Vibration

• Air removal

• Controlled filling height

Heat-Seal Settings

Sealing temperature, pressure, alignment, and dwell time should be established through pouch testing.

Too little heat or pressure may create an incomplete seal. Excessive heat may deform the film, damage the zipper, or affect pouch appearance.

Seal Inspection

Production checks should include:

• Seal appearance

• Seal width

• Wrinkles and folds

• Product contamination

• Leakage

• Burst or peel testing where required

• Date-code position

• Net-weight verification

The required inspection method depends on the product and applicable packaging standard.

Six- or Eight-Station Operation

The MSZP8-200 is available with six or eight mechanical stations. The final station arrangement depends on the product and pouch process.

A configured sequence may include:

1. Pouch feeding

2. Pouch gripping

3. Coding or opening

4. Pouch opening and detection

5. Product filling

6. Product settling or secondary filling

7. Heat sealing

8. Cooling and discharge

The actual station allocation should be shown in the final machine drawing. An eight-station configuration may provide more space for secondary filling, settling, cleaning, sealing, or inspection functions.

Production Speed

The published maximum speed is up to 60 bags per minute.

Actual output depends on:

• Product type

• Target filling weight

• Dosing-system speed

• Pouch dimensions

• Pouch quality

• Zipper or closure structure

• Number of operating stations

• Filling accuracy

• Sealing dwell time

• Product settling requirements

• Upstream product supply

The maximum mechanical speed should not be treated as guaranteed production output for every product.

Sauces, difficult powders, fragile snacks, large fill weights, or products requiring long settling times may operate below the published maximum.
