Vertical Form Fill Seal Machine For Powder

The Vertical Form Fill Seal Machine for Powder is a packaging machine that automates the entire process of powder material production, from raw material to finished bag, including bag making, filling, and sealing, using a screw metering system. This packaging method reduces labor costs, improves packaging efficiency, and provides precise measurement of each bag's weight, with an error controlled within ±1g, ensuring consistency across all bags. It can package 30-150 bags of powder per minute and supports three-side seal, four-side seal, back seal, and pillow-type bag types. Typical dimensions are 30-200mm wide and 50-300mm high, but customization is also available.

The Vertical Form Fill Seal Machine for Powder can be used for packaging dry, free-flowing powders, granular powders, and lightweight powders such as flour, milk powder, spices, cocoa powder, traditional Chinese medicine powder, and feed powder. Each bag can be sized from 1-5000 grams. However, it cannot be used for packaging highly hygroscopic and easily caking soda powder, ultrafine easily airborne graphite powder, flammable and explosive gunpowder powder, or corrosive powder. These powder materials can easily cause machine blockage, inaccurate measurement, or safety risks.

What types of Vertical Form Fill Seal Machines for Powder are there?

The metering method used in Vertical Form Fill Seal Machines for Powder varies depending on the type of powder being packaged and the production volume requirements. There are three main types: screw type, measuring cup type, and weighing type.

Screw-type Vertical Form Fill Seal Machine for Powder: This machine measures and pushes powdered material by the number of screw rotations. It is used in conjunction with vertical bag making and heat-sealing processes to package powdered materials. Each bag can be sized from 1 gram to 5 kilograms, with a packaging speed of 40-80 bags per minute. It can be used for packaging fine powders, micro powders, and powders with moderate flowability, such as milk powder, traditional Chinese medicine powder, protein powder, flour, and coffee powder.

Measuring Cup-type Vertical Form Fill Seal Machine for Powder: This machine uses a measuring cup to quantitatively scoop powdered material, which is then filled into forming bags through the feeding port. Each bag can be sized from 5 grams to 500 grams, with a packaging speed of 30-150 bags per minute. This is the fastest packaging speed and is commonly used for packaging free-flowing, non-clumping powders such as sugar powder, monosodium glutamate powder, feed premix powder, and laundry detergent.

Weighing Vertical Form Fill Seal Machine for Powder: This machine uses an electronic scale to accurately weigh the material and then feeds it into a forming bag for sealing and packaging. It has the highest measurement accuracy, but the packaging speed is relatively slow, generally 10-40 bags/minute. It is often used for packaging high-value powders and powders that require precise measurement, such as health product powders, Western medicine powders, precious metal powders, and chemical raw material powders.

What are the advantages of a Vertical Form Fill Seal Machine for Powder?

How does the Vertical Form Fill Seal Machine for Powder work?

When the Vertical Form Fill Seal Machine for Powder is in operation, the roll film is stretched vertically and folded into the desired bag shape. The formed packaging bag moves downward to the filling position, and the powder is fed into the opened packaging bag through a metering device. The bag filled with powder moves downward to the sealing position for heat sealing, and at the same time, the connected packaging bags are cut. The finished product is then conveyed to the next process for further processing.
