In the beverage market such as instant coffee, protein powder, and milk tea powder, bag packaging has become the mainstream choice due to its portability, hygiene, and precise quantitative characteristics. An efficient beverage powder bag packaging machine can not only improve production efficiency, but also strengthen the brand image through exquisite packaging. This article will analyze the types, applicable scenarios, and purchase points of bag packaging machines to provide practical reference for manufacturers.   What are the different types of bag packaging machines? Beverage powder bag packaging machines are mainly divided into the following three categories according to packaging form and function:   (1) Vertical Forming-Filling-Sealing (VFFS) Working principle: The roll film is automatically formed into a bag shape → accurately filling powder → heat sealing and cutting. Applicable scenarios: 1-100g small bags, such as instant coffee, seasoning powder, etc. Advantages: Strong compatibility, can produce a variety of bag types such as back seal, three-side seal, self-supporting bag, etc.   (2) Strip packaging machine Working principle: Fold the film into a long strip → heat seal at both ends after filling. Applicable scenarios: 10-50g portable strip packaging, such as meal replacement powder and single-drink products. Advantages: Save packaging materials, neat appearance, suitable for multi-flavor combination packaging.   (3) Prefabricated bag packaging machine Working principle: Manual or mechanical hand feeding prefabricated bags → automatic bag opening, filling, and sealing. Applicable scenarios: high-end gift packaging, special-shaped bags (such as bags with zippers or nozzles). Advantages: Flexible packaging design, suitable for high value-added products.   In addition, strip packaging machines are also commonly used for large-volume (more than 200g) powder packaging, such as protein powder canned supplement packaging.     What materials can be used for beverage powder small bag packaging machines? The packaging material must take into account moisture resistance, sealing and aesthetics. Common choices are: (1) Aluminum foil composite film: Oxygen and light blocking, extended shelf life, suitable for products with high freshness requirements.   (2) PET/PE film: low cost, suitable for short-term circulation such as milk tea powder and cocoa powder.   (3) Degradable materials (such as PLA): Emerging under the environmental protection trend, the equipment needs to adapt to low-temperature heat sealing parameters.   Taking the fully automatic packaging machine as an example, high-end models can intelligently adjust the heat sealing temperature and are compatible with different materials to avoid loose sealing due to differences in film materials.   How to choose a food packaging machine?

In the powder production industry, packaging is not only a key barrier to protect products, but also a direct reflection of brand image and consumer trust. From moisture and pollution prevention to precise metering, efficient powder packaging machines can significantly improve production efficiency and product quality. This article will explore the core knowledge of packaging machines in depth, introduce equipment types, working principles and common techniques.   What is a powder packaging machine? Powder packaging machines are automated equipment designed specifically for powdered and granular products. They complete packaging through metering, filling, sealing and other processes. The characteristics of powder packaging machines are:   (1) Workpiece metering: The workpiece can be controlled within ±0.5%-1%, which is suitable for high-priced products such as milk and protein powder.   (2) Design: Sealed operation avoids powder flying and meets food-grade hygiene standards.   (3) Multi-bag equipment: supports back-sealed bags, self-supporting bags, stick bags, etc.   Taking the automatic milk powder packaging machine as an example, this type of equipment can integrate nitrogen filling and preservation functions to extend the shelf life of milk powder, which is especially suitable for the production of infant formula milk powder and the use of complementary food powder sticks.     How does a powder packaging machine work? The typical milk packaging process is divided into the following steps:   (1) Film feeding and bag making: The rolled film enters the forming machine through the guide roller, and the heat sealing device initially forms the bag shape.   (2) Measuring filling: The screw feeder or gravity sensing system accurately feeds the milk powder to ensure that the weight of each bag is consistent.   (3) Exhaust and seal: After the air in the bag is extracted, heat seal it to prevent oxidation and agglomeration.   (4) Cutting and output: Cut into independent packages, automatically stack or pack.   For small-sized products (such as 10-50g portable packaging), stick packaging machines (with outstanding efficiency, reaching 200-400 packages per minute, and appearance such as easy preparation, different packaging requirements correspond to different packaging machines, and the packaging machine selected is based on your production needs.   What machine should be selected for milk packaging? (1) Live vertical packaging machine: Applicable types: canned and bagged milk powder, supporting 100g-2kg specifications. Advantages: integrated weighing, filling, and coding functions, compatible with powder filling equipment expansion.   (2) Strip packaging machine (stick packaging machine): Applicable types: single-time small packaging (10-50g), distribution and retail. Advantages : Save packaging material costs, suitable for multi-variety mixed production lines.   (3) Pre-m...

With the booming food, pharmaceutical and daily chemical industries, stick pack packaging machines are bringing about new changes in the packaging field with their unique packaging form. This article will analyze the essential differences between bar packaging and pouch packaging from the perspective of practical application, and provide professional advice for purchasing high-performance stick packaging machines.   What is the difference between bar packaging and pouch packaging? In the packaging field, although bar packaging and pouch packaging look somewhat similar, the actual difference is not small.   (1) Pouch packaging is usually a relatively square or nearly square packaging form with a relatively large volume. It can hold more products, whether solid, liquid or semi-solid. It can be well accommodated. It is commonly used in snacks, condiments and other packaging.   (2) Bar packaging is in the shape of a slender strip, which is significantly different from pouch packaging in shape. Its volume is generally smaller and is more suitable for packaging small-dose products, such as liquid medicines, concentrated essences, etc.   (3) In terms of packaging technology, pouch packaging is mostly three-side sealed or four-side sealed, while bar packaging is mostly two-end sealed. In practical applications, small bag packaging pays more attention to the storage volume and integrity of the product, while bar packaging focuses on the portability and precise quantification of the product.     What is a stick packaging machine A stick packaging machine, also known as a stick pack packaging machine, is a device specifically used to produce stick packaging. The stick packaging machines we are talking about can accurately fill liquids into special stick packaging materials, and then perform a series of operations such as heat sealing and cutting to complete the entire packaging process. This machine is widely used in industries such as food, medicine, and cosmetics. For example, some single-dose liquid drinks, oral liquids, or beauty essences, etc., are inseparable from it. It is somewhat similar to a food packaging machine, but it has its own unique features. Food packaging machines cover a wider range, while stick packaging machines focus on stick packaging, and are more targeted in terms of the accuracy and packaging form of liquid packaging.   How to choose a stick packaging machine Packaging requirements: First, you must clarify the characteristics of your liquid products, such as thick sauces or thin lotions, which will affect the selection of the filling system of the machine. If it is large-scale production, you need to choose equipment with fast packaging speed and high production capacity; if it is a small batch and multi-variety production mode, the flexibility and adjustability of the machine are more important.   Equipment quality: Choosing a well-known packaging machine manufacturer is the key. The strip...
