READ MOREStand-up pouches can effectively prevent air from entering the pouch to maintain the freshness and taste of the jelly, which is especially important for products that need to be kept fresh, such as fruit juice jelly. Stand-up pouches with suction nozzle design, easy for consumers to drink and storage, use can be screwed on the lid, can be re-sealed after use, to maintain product hygiene. So that consumers can easily suck and drink juice and jelly, juice and jelly stand-up pouches are designed to be beautiful and generous, which can enhance the image and quality of the product and attract consumers' eyes. Juice jelly stand-up pouches are lightweight and compact, easy to carry, suitable for consumers to enjoy at any time when going out, traveling, work.

READ MOREWhen discussing the sealing technology of juice and 1kg jelly stand-up pouches and the mechanism to ensure tightness and firmness, we have to deeply analyze the advanced manufacturing technology and innovative design concepts mastered by our company, which are the key to our ability to stand out in the fiercely competitive market. The following will comprehensively explain how we achieve efficient and reliable sealing technology and how to ensure the safety and quality of products in the whole chain from multiple dimensions such as technical details, production process, quality control and material selection.
One of the core of our production line is equipped with ten high-speed three-side sealing (stand-up bag) bag making machines. These equipment use advanced servo control systems to accurately control the tension, temperature and pressure of the film to ensure high consistency and accuracy of the sealing process. In the sealing process, the machine uses high-frequency heating or ultrasonic welding technology to quickly and evenly seal the three sides of the stand-up pouch. High-frequency heating technology uses high-frequency electromagnetic fields to generate frictional heat between plastic molecules, so that they reach the fusion point in a short time and form a strong seal; while ultrasonic welding uses the energy generated by high-frequency vibration to make the molecules between plastic layers penetrate and combine with each other to achieve seamless connection.
In order to further improve the sealing efficiency and quality, we have configured 15 self-supporting bag automatic tube pressing machines. These devices integrate automatic identification and positioning technology, which can accurately press the straw hole at the predetermined position and seamlessly connect with the sealing process. Through the intelligent control system, the depth, strength and angle of the tube pressing can be adjusted according to the needs of different products to ensure that the area around the straw hole is tightly sealed without leakage risk. In addition, the tube pressing machine also has an automatic detection function, which can monitor the sealing quality in real time. Once an abnormality is found, it will immediately alarm and shut down, effectively preventing defective products from flowing into the next process.
In terms of material selection, we strictly select high-quality food-grade plastics such as polyethylene (PE) and polypropylene (PP) as the main materials for self-supporting bags. These materials not only have good chemical resistance, low temperature resistance and certain toughness, but are also easy to process and shape, making them ideal choices for making self-supporting bags. At the same time, we use multi-layer co-extrusion technology to compound plastic layers with different properties to form a multi-layer structure, which further improves the barrier and mechanical strength of the bag.
In the sealing process, the control of temperature and pressure is crucial. Our bag making machines and tube pressing machines are equipped with precise temperature control systems and pressure sensors, which can monitor and adjust the heating temperature and pressure values in real time to ensure that the seal reaches the best fusion state. Too high or too low temperature may cause the seal to be loose or the material to deform, while the appropriate pressure can ensure the tight combination of the seal and effectively prevent the intrusion of air and moisture.
To ensure the sealing quality of each self-supporting bag, we have established a strict quality inspection system. In addition to automatic inspection on the production line, we also have a special quality inspection team to conduct sampling inspections on finished products, including sealing strength testing, sealing testing, and appearance inspection. At the same time, we use QR code or barcode technology to establish a unique identity for each self-supporting bag to achieve full traceability of the production process. Once a problem is found, the cause can be quickly located and corresponding measures can be taken.
In addition to technical guarantees, we also focus on the optimization of packaging design. The unique bottom structure design of the 2kg stand-up pouch enhances the stability of the bag body. Even if it is squeezed by external forces during transportation or storage, it can maintain its shape, thereby protecting the seal from damage. In addition, the nozzle design is not only convenient for consumers to use, but also can enhance the sealing effect of the seal to a certain extent, reducing the risk of leakage caused by misoperation.
Our company has set an industry benchmark in the production of juice and jelly stand-up pouches with advanced production equipment, exquisite process technology, strict quality control and innovative design concepts. From high-speed three-side sealing bag making machines to automatic tube crimping machines, from material selection to sealing quality testing, every link embodies our unremitting pursuit of quality and continuous exploration of technology. We are well aware that only by continuous innovation and improvement can we meet the growing needs of the market and customers and ensure that our products always maintain a leading position in the fierce market competition.
