This two-layer packaging machine is specially developed for milk bottle packaging, equipped with two sets of fully independent packaging units integrated in one compact frame. Each unit can run separately or work in parallel, completing bottle sorting, grouping, film wrapping, heat-sealing and finished-product output for milk bottles automatically.

Built with food-grade stainless steel, it meets dairy-industry hygiene standards. It supports dual-mode production: double-line high-speed simultaneous operation for higher output, or single-line independent running for mixed-specification packaging. It is widely applied for PET milk bottles, dairy beverage bottles in milk-processing factories, realizing flexible and stable large-volume packaging production.

• Two independent full-function packaging units: Two complete sets of packaging systems with separate driving, sealing and control modules. One unit can keep running while the other unit stops for mold change, maintenance or cleaning, avoiding full-line shutdown and improving overall equipment availability.
• Dual-mode flexible production: Parallel operation for doubled throughput; separate-unit mode supports producing different bottle sizes or packaging specifications on two lanes at the same time.
• Food-grade hygienic construction: Main contact parts adopt 304 stainless steel, smooth surface for easy cleaning, compliant with dairy food-safety requirements for milk bottle packaging.
• PLC & touch-screen centralized control: Unified HMI for parameter setting; each independent unit can also adjust speed, sealing temperature and packaging parameters individually. Real-time fault alarm and status display for easy operation and troubleshooting.
• Stable two-layer wrapping performance: Precise film feeding and heat-sealing mechanism ensures tight two-layer packaging for milk bottles, firm sealing effect, less film waste, good anti-dust and anti-collision performance for finished packages.
• Compact integrated structure: Two independent units are assembled in one machine frame, saving workshop floor space compared with two separate standalone machines, convenient for installation and on-site layout.
• Wide adaptability: Quick-change structure supports fast adjustment for different milk-bottle diameters, heights and packaging group quantities; compatible with various heat-shrink packaging film materials.

The overall product quality has traceability, and the product quality warranty period is 1 year, calculated from the date of equipment acceptance.
