  The dairy industry is advancing rapidly, with an increasingly diverse range of products—especially chilled fresh milk. Packaging formats vary significantly in both shape and material. In practice, dairy packaging is commonly categorized as follows:

  • Cartons: such as Tetra Pak®, Combibloc®, and gable-top (roof-shaped) cartons.
  • Plastic bottles: including PET, PP (polypropylene), and PE (polyethylene) bottles.
  • Plastic cups: typically used for yogurt.
  • Metal cans: used for certain specialty or long-life dairy products.

  When designing labeling solutions, labeling machine manufacturers must consider not only the packaging material and format but also the hygiene and cleanliness requirements of the production environment. The dairy industry imposes strict demands on labeling: systems must deliver high-speed performance while ensuring that pressure-sensitive labeling equipment does not contaminate the production area. Both conditions are essential and non-negotiable.

  Commonly used fully automatic labeling machines in the dairy sector include rotary labelers and fully automatic flat-surface labelers.
  
  

  Advantages of SpeedPack automatic labeling machines: high labeling accuracy, wrinkle-free and bubble-free application, simple adjustment, and quick changeover between different products and label types. Optional integration with inline print-and-apply labelers or inkjet coders enables real-time printing of electronic supervision codes, production dates, batch numbers, barcodes, and QR codes for traceability, anti-counterfeiting, and anti-diversion purposes. Vision inspection systems and conveyors can also be added to enable automated visual inspection and rejection of defective items.

  For fully automated production lines, SpeedPack offers integrated solutions that may include bottle rinsers, fillers, multi-functional inspection systems (with customizable detection and rejection capabilities), barcode traceability platforms, and electronic supervision code systems (supporting authenticity verification and geo-based anti-diversion tracking). Products are transported downstream via gripper conveyors for secondary packaging operations such as case packing, palletizing robots, case packing robots, and case sealing and strapping.

  SpeedPack is committed to the R&D and manufacturing of automated packaging equipment. We offer a full range of labeling machines, including pressure-sensitive label applicators. Our fully automatic flat-surface labelers are designed to apply labels or adhesive films onto the top surfaces of various items. By simply changing the labeling head module, the system can also handle uneven surfaces, making it suitable for large-format or irregularly shaped products.
