The volumetric weigh filler back sealing powder packing machine is an accurate device that can dispense precisely dosed powders into the sachets by measuring them.

7.What do you mean by free-flow and non-free-flow powders in the back sealing powder packing machine?

Free Flow Powder (Granulated Sugar) vs Non-Free Flow Powder (Powdered Milk)

Free-flow powders have non-cohesive particles, like in granulated sugar. It implies that they will flow easily while dispensing and no additional pressure exertion can compress or manipulate them.

Non-free-flow powders have cohesive particles, like powdered milk. They do not flow easily. Moreover, extra pressure can be applied to manipulate their structure into any desired form.

There is an unorthodox way to determine the nature of the powder (free-flowing or non-free-flowing), and that is the “Finger Test”.

Finger Test

Poke a finger into the vessel containing the powder. A non-free-flow powder will remain indented after finger removal (after initial pressing). On the contrary, in free-flow powder, the indention will not sustained.

This property determines the filler type you would need for your product’s efficient dispensing. For free-flow powder, an auger or volumetric cup filler will be preferred while for non-free-flow powders, a special auger filler can be utilized capable of handling the sticky products.

8.Why is it important for the back sealing powder packing machine to have suitable packaging material? 

The correct packaging process is vital for maintaining the freshness and quality of your product. You can satisfy your consumer’s demands by selecting the appropriate packaging material and device.

Not convinced?

We are enlisting the primary reasons why choosing the right powder packaging and the back sealing powder packing machine is so important:

Airtight packaging prevents the product from humidity, air, and light which are the primary factors involved in the reduction of the product’s quality and freshness.

The packaging must be moisture-proof to avoid bacterial growth which can result in the degradation of the product, ultimately affecting its safety.

Light-resistant packing aids in the protection of products from UV rays: which can cause the degradation of certain products.

The right packaging and efficient processing help extend the product’s shelf-life.

So, it is important to ensure the right packaging material for each product type, but it will not be enough in case of the wrong selection of the device. It means that both the right packaging material and the back sealing powder packing machine are crucial for effective packaging.

9.What are the different filling techniques in the back sealing powder packing machine?

There are several filling techniques applied in the back sealing powder packing machine. The common ones are:

Auger Fillers

Auger Filling Mechanism

The powdered material is poured/kept in a cone-shaped hopper. The powder gets filled into the sachets using an auger screw/conveyor. The amount of the product to be dispensed can be controlled by regulating the number of rotations of the screw.

Volumetric Weigh/Cup Fillers

Volumetric Weigh/Cup Filling Mechanism

This is a suitable filling technique for linear feeders. It is flexible, accurate, and has a rapid speed. This type of filler measures the powders in precise weights and then fills them into pouches.

10.What should be done to extend the life of your back sealing powder packing machine?

Maintenance of the Back Sealing Powder Packing Machine

11.What are the causes and countermeasures for sealing defects of the back sealing powder packing machine?

Sealing Defect/Failure

“Sealing Failure” is the most common issue encountered in the back sealing powder packing machine. They are frequently caused by improperly adjusted settings. Seal failure can be referred to as various forms of sealing defects, like incomplete seal, wrinkled seal, etc. It not only has an impact on the product’s quality but also creates a negative image of the brand, leading to adversely affecting sales.

Cause and Countermeasures

The packaging films are of various types, each differing in characteristics and requiring proper processing settings, otherwise, a defective sealing can result. The main causes are:

Causes of Sealing Failure

Improperly Adjusted Sealing Temperature

The packaging films vary in thickness. Each of them has a suitable temperature setting for sealing. In case of non-adjustment of the temperature, a defective sealing will be the outcome.

Countermeasures

Always check and validate the suitable temperature setting for the respective packaging film to avoid shrinkage or unevenness in sealing.

Inadequate Time of Sealing

For efficient working, a rapid production speed is required. However, the inadequate sealing time will result in the sealing failure, the frequent one is the seal peeling. The inadequate time with high temperature results in a broken seal. Moreover, as the strength of the seal becomes weak, it can burst on impact.

Countermeasures

Adjust the sealing time to be sufficient for an effective seal. Select a device that allows flexibility in sealing time.

Dirty Sealing Components

It is a common defect in which a foreign matter or the product gets entry into the seal part. It is usually caused by the lack of maintenance of the device.

Countermeasures

Thorough cleaning of the sealing components is necessary. Inspect that no film particles/residues are remaining on the sealing station.
