Stand Up Pouch Packing Machine Selection Guide & Product Overview

I. What is a Stand Up Pouch Packing Machine?

The Stand Up Pouch Packing Machine is highly efficient packaging equipment designed specifically for processing premade pouches (such as stand-up pouches, flat bags, zipper bags, etc.). The machine replaces manual labor with automated mechanical actions to complete the tedious process of bag picking, bag opening, and sealing.

Core Value： Completely resolves the pain points of manual packaging, such as low efficiency, ugly sealing, and poor sealing causing leakage. This series of mainframes features extreme compatibility: For flowable materials like liquids, pastes, powders, and regular granules, it can be paired with various automatic fillers (like pumps, weighers, augers) for fully automatic packaging. For irregular, easily tangled, or hard-to-handle materials, it allows for manual collaborative feeding, providing a low-cost solution for automation blind spots.
Applications： Widely used in snacks, food, condiments, agricultural products, daily chemicals, cosmetics, hardware accessories, and many other industries.
Unified Specifications： All machines in this series support 110V/220V power supply, offer a massive compatible bag size range (from 5×7cm to 20×30cm), and require an external air compressor providing 0.6-0.8 MPA stable air pressure.

Core Workflow Introduction

The core of the stand up pouch packing machine is breaking down complex packaging actions into a highly coordinated assembly line process:

Bag & Material Preparation (Pre-process)
Bag Loading：The operator places a stack of premade pouches into the large-capacity bag bin (holds up to 450 bags).
Material Prep：Depending on the model, materials are poured into the top hopper, sucked from a ground-level raw material drum, or prepped by workers beside the assembly line for manual feeding.
Auto Bag Opening & Filling/Feeding (Core Process)
Picking & Opening：The machine suction cup automatically picks up the pre-made bag, and a pneumatic device opens the bag's mouth.
Material Filling (Two Modes)： Fully Automatic Filling: Devices like liquid pumps, powder augers, or electronic weighers inject the exact preset weight/volume into the bag. Manual Collaborative Feeding: For irregular items machines struggle with, workers can drop materials directly into the bag (Manual Feeding Model), or drop them into a constantly moving bucket conveyor (Bucket Conveyor Model) which then automatically dumps the material into the bag.
Thermal Sealing & Output (Post-process)
Mesh Thermal Sealing：Utilizes high-quality mesh-pattern sealing molds (without steel printing) and heating tubes, combined with sealing temperature, ensuring flat, secure, and leak-proof seals with no trapped materials.
Output：Once sealed, the finished product automatically drops onto the outfeed, completing the packaging loop.

II. Core Models Selection & Specification Tables

To meet the packaging needs of different material states (liquids, powders, regular granules, irregular items), we have categorized our equipment into the following 3 main series:

1. Liquid & Paste Filling Series (For Pure Liquids, Thick Pastes & Mixed Sauces)

Fully automatic pump filling systems designed for various fluidities and viscosities.

Model	Applicable Material	Core Filling Device	Key Features
DGD-W30TD-W-YSK280	Pure Liquid (No impurities/viscosity)	Digital Control Self-priming Pump	Zero-washing-hopper model. Hose drops directly into ground material drums. ±0.1g accuracy. To change materials, simply pump clean water to flush. Completely ends the nightmare of frequent pouring and hopper washing.
DGD-W30TD-W-G300	Paste & Liquid	Pneumatic Plunger Pump + 30L Hopper	Comes standard with a 30L stainless steel hopper and a pneumatic plunger pump. Features an auto-blowoff system to prevent stringing/dripping when filling viscous pastes (like ketchup). Split-type design offers ultimate cost-effectiveness.
DGD-W30TD-W-J500	Mixed Sauces (Particle + Paste + Liquid)	Pneumatic Plunger Pump + 80L U-Shaped Stirring Hopper	The Sauce Specialist. 80L U-shaped hopper features stirring, solving the "oil-water separation & granule sinking" pain points. Ensures every pouch has the perfect golden ratio of meat/chili to oil. Equipped with a 28mm blowoff filling nozzle for smooth discharge.

2. Solid & Bulk Material Series (For Powders & Regular Granules)

Fully automatic weighing/dosing systems designed for powders and granules requiring precise measurement.

Model	Applicable Material	Core Measuring Device	Key Features
DGD-W30TD-W-F500	Powders	Vertical Auger Filler + 16L Hopper	The Anti-Dust Solution. The auger nozzle extends directly inside the bag for deep quantitative powder filling. Effectively prevents dust from flying and contaminating the sealing area, which causes leakages.
DGD-W30TD-W-K500	Regular Granules	Three-head Electronic Linear Weigher + 30KG Hopper	Supports Multi-Material Mixing. The 3 electronic weighers can discharge in turn or simultaneously. Not only achieves ±0.1g precision but also allows operators to set mixed ratios of different materials (e.g., rice + mung beans) directly on the touch screen.

3. Irregular Items & Manual Synergy Series (For Non-standard & Irregular Items)

When materials are irregularly shaped, easily tangled, rendering automatic fillers useless, this series perfectly combines the "flexibility of humans" with the "high-efficiency sealing of machines."

| Model | Applicable Material | Feeding Method | Key Features | | :--- | :--- | :--- | :--- | :--- | | DGD-W30TD-W | Irregular items, Small-batch testing | 100% Manual Feeding |A versatile host machine occupying < 1 sq. meter. Ideal for manual drop-ins of hotel amenities, hardware, etc. Can be pre-equipped with a universal signal interface to easily upgrade to a fully automatic line with external fillers in the future. | | DGD-W30TD-W-FD | Blocky items, easily tangled, chaotic goods | 1.5m Bucket Conveyor (3-4 workers synergy) | Capacity-doubling assembly line. Supports 3-4 workers standing alongside. The conveyor runs at a fixed pace, forcing workers to feed continuously (e.g., sausages, laundry pods, mixed nuts). Supports multi-item mixed feeding with automatic dumping. |

III. Technical FAQ & Selection Advice

1. Model Selection Advice

**Q1：How do I choose the best stand up pouch packing machine for my product?
A： Step 1: Look at the material state. Pure water-like liquids -> YSK280; Powders -> F500; Sauces -> J500; Regular granules -> K500. Step 2: Look at the shape and packaging difficulty. If your product is highly irregular (like whole sausages) or fragile (like laundry detergent pods), don't hesitate—choose the FD (Bucket Conveyor) or the base W (Manual Feeding). Using human logic to sort and feed, combined with automatic machine sealing, is the most stable and cost-effective solution.
Q2：Is it difficult to adjust the machine for different bag sizes?
A： Not at all. The entire series supports a huge compatible bag range from 5×7cm up to 20×30cm. To switch sizes, you just need to adjust a few mechanical knobs on the machine and tweak the parameters on the touch screen. The changeover can typically be completed within a few minutes.

2. Operating Conditions & Maintenance

Q3：Can I use this machine just by plugging it into an electrical outlet?
A： No, electricity alone is not enough. The entire pouch packing series (including pneumatic pumps, and suction cups,etc) is driven by compressed air. You must prepare an air compressor to provide a stable air supply of 0.6-0.8 MPA for the equipment.
Q4：Why does the sauce machine (J500) come standard with a "U-shaped" stirring hopper? Won't a regular round one work?
A： Standard round hoppers have uneven gravity and dead zones at the bottom, causing meat granules/chunks in the sauce to sink. Our U-shaped hopper provides 360° dead-angle-free tumbling and stirring, guaranteeing that the "oil-to-meat ratio" is exactly the same from the first bag to the very last.

IV. Manufacturer Customization & Accessories Ecosystem

As an original manufacturer, our host machines have extreme scalability, supporting a variety of custom and optional add-ons:

Date Printing： To meet expiry date printing needs, we support adding Steel printing, Ribbon printers, or Laser inkjet printers.
Freshness Solutions： For food clients (like sausages or nuts), we can add Vacuum devices or Nitrogen flushing devices to significantly extend shelf life.
Bag Bottom Tapper/Vibrator： For lightweight materials that tend to pile up inside the bag (like dried fruits), a tapping device can be added to shake and settle the materials after filling, preventing them from getting trapped in the top seal. (Limited to stand-up pouches).
