Modern Powder Packaging: Automation With Powder Pouch Packing Machines

Powdered products can be found in various industries, including cosmetics, foods, chemicals, agriculture, medicines. Compared with liquids and solid granules, powders behave differently. They are easy to clump, and may create dust in the air. For manufacturers, it is a challenge to cleanly and efficiently to pack powders into pouches. This is why automatic powder pouch packing machine become an essential solution.

In this article, we will discuss the challenges of powder packaging, how powder pouch packing machine solve these problems, and various types of machines available.

Challenges of Powder Packaging

1. Poor Flowability

Many powders couldn’t flow smoothly. Some powders will clump together due to state electricity and moisture absorption, such as cocoa powders, matcha powders. This makes it not weigh and fill the powders accurately.

2. Dust Generation

Powder particles are small and light. They will float in the air and create dust during packaging process. This dust can make the factory floor become dirty. For the workers who inhale the substances for a long time, their respiratory system could be irritated and thereby lead to chronic health issues.

3. Inconsistent Filling Weight

When powder is packed by hand, the amount in each bag can be different. Some bags get too much powder, and some get too little. This is a problem for both the company and the customer. Too much powder wastes money. Too little powder can break trust with buyers or even break the law in some countries.

4. Package Seal Integrity

Powder particles are easy to stick at the pouch opening. When powders get stuck there, the machine could not seal the pouches tightly. This will cause product leakage and contamination.

5. Product Contamination

Food, pharmaceutical and cosmetic powders need to produced in a clean production environment. If human hands touch the powder too much, it will lead to a higher risk of contamination.

6. Low Efficiency of Manual Packing

Measuring powders, filling powders and sealing pouches by hand will take a lot of time. It also needs many workers to meet the target volume. When demand increases, manual packing can not keep up with the large orders.

How a Powder Pouch Packing Machine Solves These Problems

• Handles moisture-sensitive powders: Many machines are built with vibration systems or stirring blades. They are designed for preventing powders from getting clumping. This allows for smooth powder flowing and filling.
• Reduces dust and spillage: The machine has a close filling system. Powders will be transferred through sealed pipes and hoppers. And the filling nozzle of machine can be equipped with a vacuum dust collector, which can effectively avoid dust generation.
• Improves weighing accuracy: When filling fine powders, machines will use auger fillers to realize accurate powder dosing. When handling powders that contain particles, machines will utilize measuring cups or weighing system to dispense exact volume of powders into each pouch.
• Performs secure sealing: The filling nozzles will reach into the pouches to fill powders. This can prevent powders from getting stuck at the opening and keep the seal area clean. The temperature of sealing system can be adjusted to handle different pouch materials.
• Improves product hygiene: The powder measuring, filling, and pouch sealing are performed automatically by the powder pouch packing machine. This reduces human contact with materials and also reduces risks of contamination.
• Increase production output: An automatic powder pouch packing machine can produce 1200-1800 pouches per hour. This is much faster than a team of workers.

Different Types of Powder Pouch Packing Machines

Powder pouch packing machines have different configurations and working processes. Each of them is suitable for different powder formulations, pouch designs, and production demands.

1. Vertical Form Fill Seal Machines

These machines form the pouch from a film roll, fill it with powders, and seal it. These actions are completed in a continuous vertical motion. They can be customized to make different pouch shapes and sizes.

How it works:

• Material Feeding: A screw feeder will transfer powders into hopper. Then the stirrer inside the hopper will keep the powders flowing and prevent clumping.
• Film Feeding & Pouch Forming:A flat roll of packaging film will be pulled and shaped into pouch tubes.
• Material Filling:The auger screw will accurately measure and fill powders into pouches. It can be changed to fill different volumes of powders.
• Sealing & Cutting:Heated sealed jaws will clamp and bond the films together, then and cutting blades will separate the continuous pouches into individual packs.
• Product Output:The finished pouches will be transferred to next process for inspection or cartoning.

2. Pre-made Pouch Packing Machine

Instead of forming the pouches, this machine uses pouches that are already made. It can open pouch, fill it with powders, and seal the pouch. These actions can be completed in a rotary or linear system. The machine offer more premium packaging and greater format flexibility.

How it works:

• Pouch Feeding & Opening: Vacuum suction mechanisms pick pouches from a stack and move them to opening station. Then a mechanism will open the pouch to make it ready for filling. Some machines can also be used for opening zipper locks.
• Powder Dosing: Auger mechanism will rotate in certain turns to fill a set volume of powders into pouches. Some machines will use vacuum dust collector to avoid airborne dust.
• Pouch Sealing: Sealing structures will apply consistent pressure and heat to realize airtight seal. Different sealing structures can create different patterns on pouches.
• Product Outfeeding: Finished pouches will be conveyed to next process for downstream packaging.

Benefits of Using A Powder Pouch Packing Machine

• Consistency And Accuracy: Rotating auger screws can accurately measure and dispense powders into pouches. Some machines will use servo-driven augers to enhance its consistency.
• Dust Reduction:The machine’s filling head can be connected with vacuum extraction structure, which can effectively prevent dust from becoming airborne.
• Airtight Seal: Adjustable sealing jaws can offer enough heat pressure to make pouch sealed securely.
• Material Settling:Before sealing, the vibratory plates will make powders settle into the pouches. This makes sure the pouch sealing can be finished successfully.
