The sachet packaging machine (also known as a VFFS vertical form fill seal machine) is a highly efficient automated packaging equipment. Its working principle is based on the continuous conveying and forming of film, as well as the automatic filling and sealing of products. The following is a detailed analysis of stick sachet packaging working principle:
The VFFS machine first unwinds the roll film through the feeding device and forms it into a tubular shape around a forming tube/shoulder (former). The shape and size of the former determine the width and shape of the packaging bag. Under the guidance of the former, the film follows a predetermined path to form a continuous tubular structure.
After the film is formed into a tube, the vertical sealing mechanism in vertical form fill sealing machine seals along the longitudinal direction of the film, ensuring the two edges are tightly joined to form a complete tube. Subsequently, the product is fed into the tubular film through the filling device. When the pre-set filling volume is reached, the horizontal sealing jaws (Horizontal Seal and Cut Jaw) seal and cut the film transversely to form individual packaging bags.
Precise metering devices in vertical form fill seal packager ensure consistent product volume in each bag during the filling process. After material filling, the horizontal sealing jaws will complete the top seal of the current bag (and the bottom seal of the next bag), simultaneously cutting through the sealed area to separate the bags. 마지막으로, the packaged products are discharged via the conveying device.
The working principle of the automatic vertical form fill sealer machine is simple and efficient. By replacing different formers, longitudinal sealing devices, and horizontal sealing jaws, combined with different film path designs and machine configurations, a variety of bag types can be achieved to meet the packaging needs of different products.
Back-sealed bags (also known as pillow bags) are the basic bag type produced by the Stick Packaging Machine, with the following significant features:
Simple Structure: There is a single vertical back seal, with horizontal seals at both the top and bottom ends. The overall structure is simple, requiring no complex sealing processes, making production straightforward.
저렴한 비용: Due to its simplicity, the former and sealing devices required are relatively simple, resulting in lower replacement and maintenance costs. 추가적으로, this bag type offers high film material utilization, further reducing packaging costs.
High Production Speed: VFFS packing machines can achieve high speeds when producing pillow bags. Taking a common small VFFS machine as an example, production speeds can reach 60-80 bags per minute. Our machine achieves an even higher speed of 240 bags per minute, 대규모 생산의 요구를 충족시킵니다.
Strong Applicability: This bag type is suitable for various product forms, whether granular or powdered products.
Three-side sealed bags and four-side sealed bags are more functional bag types produced by automatic sachet packing machines, with the following features and implementation methods:
Features of Three-Side Sealed Bags: In addition to the top opening, the other three sides (back and two sides) are sealed, giving the bag a flatter and more regular appearance compared to the pillow bag.
Features of Four-Side Seal Bags: After forming and filling, all four sides of the four-side seal bag are heat-sealed, resulting in a very flat, block-shaped package suitable for products with high aesthetic requirements.
Good Leakproofness: The sealing method of the four-side seal bag typically provides superior airtightness compared to the pillow bag and three-side seal bag. It is especially suitable for packaging leak-prone products like powders and liquids, effectively preventing leakage during transportation and storage.
Implementation Method:
Special Former and Film Path Design: Achieving three-side and four-side seal structures requires specialized formers and film path designs. 예를 들어, the former may incorporate a folding device that creates gussets or pre-folds the film edges during tube formation, facilitating the creation of side seals simultaneously with the back seal or enabling subsequent sealing actions. This design must be customized for specific bag requirements.
Additional Side Sealing Action (for Four-Side Seal): For true four-side seal bags, an additional side sealing action is typically required at a station after the tube is formed by the standard sachet pouch packaging process. This usually involves supplementary equipment or devices integrated into the machine to ensure the quality and accuracy of the side seals.
Shaped bags are a type of bag with a special cross-sectional profile produced by powder stick packing machines, with the following characteristics and implementation methods:
Unique Visual Appeal: The cross-section of the shaped bag is a distinct shape, 라운드와 같은, 타원형, heart, cartoon character, 등., rather than the standard rectangle or square. This unique shape provides strong visual impact, enhancing product market competitiveness.
Personalization and Customization: Shaped bags can be personalized according to different product characteristics and brand images, meeting unique customer packaging needs.
Implementation Method:
Customized Shaped Horizontal Sealing Jaws: The primary method for producing shaped bags is through the use of customized horizontal sealing jaws. These jaws not only perform sealing and cutting but their unique blade profile determines the final contour shape of the bag. Custom jaws must be designed and manufactured based on the specific bag shape requirements.
Matching with Specially Designed Film or Forming Path: In some cases, achieving optimal shaping and appearance may require specially designed film (예를 들어, with specific stretch or shrink properties) or optimized forming path designs. 뿐만 아니라, the forming path design must be tailored to the characteristics of the shaped bag to ensure the film forms smoothly without wrinkles or deformation during the tube formation process. This matching design requires comprehensive consideration of factors like film material properties, former shape and size, and the structure of the shaped sealing jaws.
The flexibility of the granule sachet stick packing machine is primarily reflected in its ability to quickly switch between producing different types of packaging bags by replacing key components, thereby meeting diverse product packaging needs. This flexibility offers significant convenience and cost-effectiveness to the packaging industry.
The former is the core component determining the basic shape and size of the packaging bag. By replacing formers of different shapes and sizes, automatic powder sachet packing machines can easily switch between producing different bag types. 예를 들어, switching from producing pillow bags to three-side sealed bags or four-side sealed bags requires replacing the former with one incorporating a folding/gusseting device. This device forms structures like gussets or pre-folds during the tube formation process, creating the necessary conditions for the subsequent sealing stages. This replacement process is relatively simple and quick, typically taking only minutes to tens of minutes, greatly enhancing production efficiency.
The horizontal sealing and cutting jaws are responsible for the final sealing and separation of the packaging bag. Their shape and design directly determine the bag’s final contour and appearance. By replacing these jaws with different profiles, the VFFS machine can produce various shaped bags on the same equipment, 라운드와 같은, 타원형, heart-shaped, and other specialty shapes. This replacement capability not only meets customers’ personalized needs for packaging aesthetics but also enhances product market competitiveness.
the stick packing machine can flexibly switch between different bag types by replacing components such as the former, horizontal sealing and cutting jaws, and others. This flexibility not only reduces equipment costs for enterprises and improves production efficiency but also enhances their competitiveness in the packaging industry, making it a highly advantageous packaging solution.
