In the packaging machinery industry, powder products have special characteristics, such as easy agglomeration and flying powder, which puts forward higher standards for how to package powder products. Choosing the right packaging affects the freshness and quality of the product, and is more related to your production efficiency and production costs. A packaging solution that is suitable and meets the characteristics of powder becomes very important. This article will introduce you how to choose packaging methods and solutions for powder products.

Today, I will introduce several bag packaging methods, namely three-side seal, back seal, and stand-up bag. You can find the packaging solution that suits you in this article. I will introduce these three solutions in detail so that you can better understand this packaging method.

Three side seal bags

The characteristic of this packaging method is three-sided sealing, that is, the bag of the machine is sealed in three places, and only one side is not sealed. Generally, the shape of the bag is rectangular or square. The production process of the edge-sealed bag is relatively simple and the cost is low. The price is more economical and affordable. The material of the bag is usually plastic film, such as polyethylene (PE), polypropylene (PP), polyester (PET), etc., or it can be a multi-layer composite film to meet different packaging needs.

Suitable materials

 suitable for powder products, such as milk, coffee powder, flour, etc. Mainly products that do not require particularly high standards of moisture-proof requirements.

This packaging method has a simple production process and fast packaging speed. The three-side sealed bag is a practical, economical and beautiful type of packaging bag, which is widely used in various industries. When choosing a three-side sealed bag, it is necessary to select a bag of suitable material and specifications according to the nature, weight, shelf life and other requirements of the packaged items to ensure the packaging effect and product quality.

Back seal bag

From the appearance, the back of the bag forms a sealing line, and the back is completely sealed by the sealing of the packaging machine. From the front of the bag, the bag is relatively flat, and generally there will be various patterns and designs printed on it. You can display your product weight and packaging information on the package, and the vertical packaging machine will print the production date and other information on the bag during packaging. The two sides and the bottom of the bag are sealed by aluminum block heat sealing, so that the bag forms a relatively closed space. This is the back-sealed bag.

The advantage of this packaging is that it is tightly sealed, which can have a high sealing effect for this kind of moisture-prone material and can extend the shelf life. The seal is on the back and the front is flat, which is conducive to printing exquisite patterns and texts.

Stand Up Pouch

The bottom of the stand-up bag has a special structural design that allows it to stand on a flat surface. The upper part of the bag is generally equipped with a zipper, a screw cap or other sealing device for easy opening and reuse. The shape of the stand-up bag can be rectangular, square or other irregular shapes.

As a new type of packaging, the stand-up bag has the advantages of strong self-reliance, good sealing, good preservation performance, convenient use and environmental protection and energy saving. The material of the stand-up bag can usually be recycled, reducing pollution to the environment. At the same time, it reduces transportation costs and energy consumption. The multi-layer composite structure and excellent barrier properties of the stand-up bag can effectively prevent the penetration of oxygen, moisture and light, maintain the freshness and taste of the items in the package, and extend the shelf life of the product.

The three types of bags I introduced above are the best packaging methods for powder products. Different bag styles can be customized according to your needs. These packaging methods are suitable for powder packaging. Choosing the right packaging solution for powder products is a process involving many considerations. From understanding the characteristics of the product to choosing the right packaging machine and supporting equipment and functions, each step requires careful consideration. I will introduce to you the packaging machines that can be matched with different sealing methods.

Back-seal bags and three-side-seal bags are suitable for most machines. Basically, most packaging machines used to package powder products can use back-seal bags and three-side-seal bags. You can choose these two sealing methods according to your own design. The following packaging machine is a powder packaging machine that can be designed with back-seal bags and three-side-seal bags.

This powder packaging machine is an intelligent machine for quantitative packaging of various powder materials. Its function is to accurately package the materials according to the set gram weight and bag length, so as to meet your sales needs, improve your work efficiency, save time and cost, and obtain greater benefits. You can tell us your needs, so that the sealing method of the packaging bag can be customized. This adopts the heat sealing method to heat the aluminum block, and the roll film is fused together through the temperature and pressure of the aluminum block to achieve the sealing effect of the packaging bag.

Features:
1. Highly automated: It can realize a series of operations such as automatic feeding, metering, filling, sealing, cutting, etc., greatly improving production efficiency and reducing manual intervention.
2. High-precision metering: It adopts advanced metering systems, such as screw metering, weighing metering, etc., to ensure the accuracy and consistency of powder packaging.
3. Versatility: It can be applied to various powdered materials, such as food powder (milk powder, coffee powder, flour, etc.), pharmaceutical powder, chemical powder, etc.
4. Stable and reliable: It adopts high-quality components and advanced manufacturing technology to ensure the stability and reliability of the machine and reduce the failure rate.
5. Easy to operate: equipped with intelligent control system, friendly operation interface, easy to operate and debug.

The sealing method of the stand-up bag packaging machine is different from the three-side sealing and back sealing methods. This packaging machine is a packaging machine specially designed for stand-up bags, which can achieve weighing-packaging-packaging-sealing in one step. The machine automatically takes bags from the bag slot, opens the bags, and transfers them horizontally to the next station. According to the set gram capacity, the screw measures and the gram is accurately and automatically filled into the packaging bag. It does not require manual labor and is efficient and convenient. Double-sided heat sealing and cutting are performed, and the sealing is neat and beautiful. To achieve the sealing effect, this packaging machine is deeply loved by entrepreneurs.

Most of the solutions for powder product packaging adopt these three sealing methods. These three sealing methods can be customized according to your preferences and can be selected based on your material characteristics and bag design. We believe that suitable packaging technology and solutions can ensure product quality, improve production efficiency, and meet the needs of the market and customers.
