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...

Solutions for packaging granular nuts Packaging bags are of great significance for packaging product materials, which means moisture-proof and quality assurance of products, so we need to package them when selling products, but for granular packaging, such as nuts and biscuits, back sealing is the best way to package granules. This type of packaging has many advantages and can be used with vertical granular powder packaging machines. This method can ensure efficient and high-quality packaging to meet the needs of modern consumers.   What is a back seal bag? From the appearance, the back of the bag forms a sealing line, and the back is completely sealed by 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 a back-sealed bag. Advantages of back seal bags 1. Tight sealing, strong sealing temperature allows the bag to seal the material tightly, which provides a dry environment for nuts and beans, and has a high sealing effect for such moisture-prone materials, which can extend the shelf life. 2. The back seal design not only seals tightly, but also reserves the design of the bag for you. You can design more attractive outer packaging to promote the sales of the machine. 3. The back seal bag adopts an easy-tear design, which is convenient for consumers to open the bag. The size of the bag can be adjusted freely. The packaging of the bag can be customized according to your material and the required weight to meet your various needs. 4. The back seal bag has a large force area. Since the sealing strip of the seal is on the back, the two sides of the bag can withstand greater pressure, reducing the chance of bag damage and better preservation.   After the above introduction, you must have a question: if I need to pack granular nuts using back-seal method, what machine should I choose for packaging? Don't worry, next I will introduce this vertical packaging machine for back-seal.   The vertical granular nut packaging machine is designed for the precise filling and sealing required for back-sealed bags. This vertical packaging machine can automatically complete volumetric filling metering-coding (optional)-bag making-filling-inflating/exhausting (optional)-sealing-counting. The control system is good and can accurately handle the gram weight of the material. It is equipped with a weighing bucket for precise packaging. The machine body and all food contact parts can be customized with 304 stainless steel. It ensures food safety, reduces product waste and ensures that each bag is properly sealed. It is an efficient an...
