100% No Leak Aluminum Foil Bag
High Quality Aluminum Foil Bag Sealing System (Clean Room Compatible)

Traditionally the heavy duty micro powder bagging machines were comprised of two separate types of equipment. One equipment was used to fill the bag with a micro powder, and the other stuff was used to seal the bag.

Once filling the bag is complete with contents, then the bag is released from the clamp and transferred to the adjacent bag sealing machine by a conveyor. Due to the movements of the bag from one position to another, the section of the sealing mouth become inconsistent resulting in poor sealing quality and loss of contents from oxidation and moisture. The sealing process involved human labor and dependent on the worker's skill level, the seal quality varied. With today's chemical industry shifting toward more value-added materials, a failure to seal the powder bag consistently with high-quality results in a substantial economic loss.

We at NLI solves the foil bag sealing problem by introducing a powder bagging machine built as a single unit for powder filling and the bag sealing. Since there is no movement of the bag from one device to another to seal the bag, the NLI's micro powder bagging and sealing whole unit system can achieve a reliable seal at a consistent level. The unit is most suitable for the use of aluminum foil bags to fill contents that are sensitive to oxidation, discoloring, and moisture.

High Speed Bagging Machine for Fine Powder
There are many production lines facing challenges in handling fine power materials.
Here are some of the reasons why fine powers are hard to deal with.

① The fine powders are easy to spread and contaminate the environment.
② High volume of air within the fine powder makes the precise measurement difficult. Also, makes it difficult to transport. Resulting in production loss.
③ 1 and 2 are the contributing factor to the limited production capacity. Treated abruptly could result in spreading of the powder from the opening cause a smoke which takes time to settle and contaminate the surface of the bag itself.

Industrial Sector that uses fine powder
A. Chemical Industry in general – Carbon, Ceramic – With our product – Reduction in product loss
B. Food: Non-fat Powdered Milk, Wheat Flour, Mixed Flour -With our product – Increased Productivity
C. Carcinogens – Dioxin, Nickel, Tin, Sodium, etc. – With our product – Faster turnout from cleaner environment
D. Sensitive materials to oxidation or humidity – Lithium, SAP(Super Absorbent Powder) – Increased barrier

Features (why our products are superior)

Ultra High Speed Powder Bagging Machine
(Rotary type eight stations method)
Filling, Weighing, and Correction Input by three stations ensures high capacity of powder bagging.

Minimal Dust Generation
Dust generation is minimal because the products are filled while the gap between product discharge port and product surface is kept minimal using the augar screw type filler (packaging machine filter).

Stable Accuracy
Augur Screw (single filling method) and built-in load cells are used to weigh and fill the products for high accuracy and stable weighing and packaging.

Handles Multiple Products
Compatible with various specifications with ease including powder, fill quantity, etc. There is no contamination since all parts that are in contact with powder can be disassembled for cleaning.

How small is a fine powder and what is the unit?

Expressed in a unit called Mesh. 1 inch by 1 inch square is 8 mesh. For example, Wheat Flour is said to be around 200 mesh. Corn Starch about 110 to 200 mesh. Carbon is about 200 mesh.

What is the capacity of NLI’s fine powder bagging capability?

It can bag fine powders between 20 to 250 mesh.
