Deep at night, when the supermarket lights go out, what truly guards the cabinet temperature is this aluminum-plastic composite night curtain with a micro-vent structure (also known as a night cover or night blind in English). Made from anti-freeze formulated fabric and aluminum foil film, it is produced through three core processes—lamination forming, laser perforation, and precision cutting and reeling. The finished curtain carries the material DNA of anti-mold and antibacterial action, low-temperature flexibility without brittleness, and resistance to repeated pulling. It ships complete with a retracting mechanism and full set of brackets, purpose-built for supermarket open chillers, vertical display fridges, convenience-store refrigerated cabinets, and catering cooling equipment.
It solves the biggest operational dilemma of open display cases—the impossibility of having both “sealing” and “breathing.” Once the curtain is lowered, the foil layer faces outward to block ambient heat while the micro-perforated side faces inward to continuously release moisture from produce respiration, keeping internal humidity within a balanced zone free of condensation and stuffiness. Cold air is retained, moisture escapes, and the cabinet temperature stays stable all night long—leafy greens no longer wilt and fruit surfaces no longer bead with water. Over time, energy and maintenance costs fall while food quality and equipment condition rise, creating a positive cycle of operating returns.
As an irreplaceable energy-saving component in commercial refrigeration, it offers a choice of manual pull-down or motorized drive, is fully custom-sized to each cabinet, and uses a quick-fit structure requiring no cabinet modification—ready for immediate use upon installation. Daily care takes only a wipe, with virtually zero extra cost throughout its service life—a small upgrade per cabinet that yields compounding dividends in energy and reduced product losses, year after year.

Visible Utility Reduction & A Fast Recovery Window
Once the curtain is lowered, your cabinet’s nighttime refrigeration load is cut by 30%–35% directly. Against the backdrop of continuously rising global electricity prices, this saving shows up on the bill every single month—most clients recoup their full investment within 6 to 12 months, and every day of use after that is a pure-profit period.
Upgrading from “Keeping Cold” to “Keeping Fresh”
Thanks to the micro-vent breathable structure, the cabinet interior is no longer a sealed, dry box, but a storage microclimate with stable temperature and balanced humidity. Greens stay crisp, dairy stays frost-free, meats and ready-to-eat items stay moist—shelf life extends naturally, and the setup easily meets food safety compliance requirements, ensuring every item a customer picks up retains its display-case freshness.
Taking the Load Off Your Refrigeration System
With the curtain in place, frequent nighttime compressor start-stops are effectively curbed, and cabinet components stay away from condensation-induced corrosion. Together, these effects slow system wear noticeably, lengthen overhaul intervals, reduce parts replacement, and push back the equipment’s retirement timeline as a whole.
Installed in Five Minutes, Worry-Free Ever After
Equipped with tool-free snap-mount brackets, a single person can install each unit in about 5 minutes—no screws, no cabinet disassembly, no business interruption. The automatic roller mechanism retracts smoothly and jams never, with zero ongoing maintenance—install it, forget it, and save all that management energy.
In the international retail and refrigeration equipment manufacturing sectors, large supermarket chain groups including Walmart and Carrefour, along with well-known refrigeration brand owners such as Panasonic and Haier, have bulk-procured and deployed this perforated breathable aluminum-plastic composite night curtain as a standard energy-saving component within their cold-chain operations. By installing this product above their open display cases, these industry leaders have effectively locked in cabinet cold air and prevented external heat infiltration during closed-store and low-traffic periods, with actual operational data showing energy consumption reductions stabilizing within the 30% to 50% range.
The perforated breathable structure accommodates normal respiration requirements of produce and fresh categories while delivering excellent thermal insulation—avoiding the quality deterioration issues associated with traditional sealed solutions due to oxygen deprivation. The direct outcome of this energy-saving initiative is notable contraction in annual electricity expenditures, while indirect benefits manifest as shortened refrigeration unit running hours, reduced compressor wear, and extended overall equipment serviceable life.
Through long-term field tracking across multiple climatic zones including North America, Europe, and Southeast Asia, this product has earned high recognition from partner organizations across thermal insulation stability, breathable freshness preservation effectiveness, and investment payback efficiency—and has now become a fixed specification item for new store openings and a preferred adoption solution for energy-efficiency upgrades in existing stores among the aforementioned enterprises.
