Unified Flex pet food packaging machines use advanced sealing technologies to ensure strong, airtight seals that protect pet food from moisture, oxygen, bacteria, and other contaminants.
- Heat Sealing: Uses controlled heat and pressure to create strong, airtight seals, preventing contamination and ensuring product freshness. This is the most widely used sealing method in vertical form fill seal (VFFS) machines, sachet machines, and stand-up pouch bagging machines.
- Ultrasonic Sealing: A high-frequency vibration sealing method that removes contaminants from the seal area, making it ideal for dusty, powdery, or oily pet food products. This technology ensures leak-proof and consistent seals, reducing product waste.
- Zipper & Resealable Closures: Available on stand-up pouch bagging machines, this sealing feature allows pet owners to reseal the bag after opening, preventing contamination from moisture and air.
- Spouted Pouch Sealing & Capping: Used in spouted pouch filling and capping machines, this technology provides a secure, tamper-proof seal for liquid pet food, broths, or meal toppers, ensuring hygiene and spill-free storage.
- Nitrogen Flushing with Sealing: An optional feature that removes oxygen from the package before sealing, preventing oxidation, mold growth, and bacterial contamination, thus extending shelf life.
By using high-quality sealing technologies, Unified Flex ensures that pet food remains fresh, safe, and free from contamination throughout storage and transportation.
