Where to Buy Dog Food Bagging Machines(vffs)?
Dog food packaging is no longer just about putting kibble into a bag. For modern pet food brands, packaging must protect product freshness, keep pellets from breaking, support attractive branding, and match the right production speed and bag format. That is why choosing the right dog food bagging machine is one of the most important decisions in a pet food production line. When people search for the best solution, they often compare three main packaging methods: fully automatic rotary pouch packaging machines for premium pre-made bags, VFFS machines for efficient roll-film packaging, and heavy-duty bagging systems for large-format packs. Among them, VFFS packaging is especially popular for mass production because it offers a strong balance of speed, efficiency, and cost control. This article explains what a dog food packaging machine is, how a dog food bagging production line works, how a vertical form fill seal machine operates, how it compares
CPHI China 2026: Discover Our Latest Packaging Lines in Shanghai
Yundu and Grand Will Meet You at CPHI & PMEC China 2026 in Shanghai Yundu is preparing for one of the most important pharmacy and packaging industry gatherings of the year: CPHI & PMEC China 2026.

The exhibition will take place from June 16 to 18, 2026, at the Shanghai New International Expo Center. For Yundu, this is more than a trade show. It is a chance to meet global buyers face to face, present practical automation solutions, and discuss how modern packaging lines can improve production efficiency. CPHI & PMEC China remains one of the largest pharma supply chain events in Asia, and the 2026 edition is expected to bring together 110K+ attendees and 3,600+ exhibitors in Shanghai. At this exhibition, we will focus on machines that
Compare rotary and horizontal premade pouch machines
Premade Pouch Packaging Machines: An Overview Premade pouch packaging machines automate the filling and sealing of preformed bags (doypacks, stand-up pouches, zipper pouches, 3- or 4‑side seal bags, spouted pouches, etc.). Unlike form-fill-seal machines that form bags from film, these machines pick, open, fill and seal ready-made pouches. They are widely used in food, beverage, pharmaceutical and chemical industries for packaging powders, liquids, granules and other products in flexible bags. Modern pouch machines emphasize hygiene (stainless steel and food-grade parts) and precision (servo drives, PLC controls) to ensure consistent fill weights and high-speed output. Pouch packaging lines may be rotary (vertical-turret) machines or horizontal machines. Both styles share many functions (bag feeding, opening, filling, sealing, discharge), but differ in layout, throughput and application. Below we compare rotary (vertical) and horizontal premade pouch machines, highlight why rotary machines often excel in high-volume lines, and explain key features of Yundu’s ZP-8R200 rotary stand-up
What is a cartridge bottle filling machine? | Yundu Machinery
Introduction In recent years, with the rapid rise of precision medicine and continuous breakthroughs in biopharmaceutical technology, the pharmaceutical packaging industry has been undergoing a profound transformation. According to the latest industry news and market data, global demand for dental anesthetics, insulin, GLP-1 weight-loss drugs, and premium medical aesthetic products such as hyaluronic acid has grown explosively. Under this trend, traditional vials and ampoules can no longer fully meet the requirements of modern precision drug delivery. This brings us to today’s core topic — the cartridge bottle and the key production equipment behind it: the Cartridge bottle filling machine. Many customers who are new to pharmaceutical production lines or considering equipment upgrades often ask: “What exactly is a cartridge filling machine? How is it different from traditional filling equipment? And how do we choose the right machine?” Today, as a professional manufacturer with years of hands-on experience, we will comprehensively
Which Products Are Best Suited for Vacuum Packaging Bags?
Which Products Are Best Suited for a Vacuum Pouch Packing Machine? Vacuum packaging has become one of the most reliable ways to protect products during storage, transport, and retail display. It helps manufacturers extend shelf life, reduce oxidation, improve product appearance, and keep packaging neat and stable. For many factories, the key question is not whether to use vacuum packaging, but which products fit it best. A modern Industrial vacuum packaging machine can do much more than simply remove air from a pouch. It can support high-speed production, stable sealing, accurate filling, and consistent packaging quality. That is why more and more food, chemical, and industrial product manufacturers are choosing vacuum pouch systems for their production lines. Yundu’s vacuum pouch equipment is designed for factories that need efficiency, hygiene, and flexible application. Based on the machine structure shown in the image, the system features a stainless steel frame, a rotary
Yundu Vacuum Packaging Machine – Best for Food, Chemical
Yundu Vacuum Packaging Machines Vacuum packaging technology is widely used to extend product shelf life. By removing air from a package and then sealing it, vacuum packaging prevents oxidation and inhibits bacteria growth. In practice, a product is placed in a flexible pouch or container inside a sealed chamber; a pump evacuates air, and then the package is heat-sealed to maintain the vacuum. This process dramatically slows spoilage. As ScienceDirect explains, vacuum packaging “removes air from the package to prevent oxidation reactions and deter deterioration caused by aerobic microorganisms, thus extending shelf life”. Busch Vacuum Technology likewise notes that vacuum-sealing “extracts air and thus the oxygen… and the product is preserved”. Yundu’s vacuum packaging solutions serve many industries. With over 20 years of experience, Yundu has grown into a premier packaging-machine supplier for the food, beverage, cosmetics, pharmaceutical and chemical sectors. The company’s equipment is used worldwide in applications ranging
