Overview
Manufactured in our 10,000+ sqm ISO 9001:2015-certified Shandong production facility using 350g imported kraft paper bases paired with crystal-clear PET transparent window lids, our square salad boxes are engineered to solve the two opposing demands that fresh-food packaging must satisfy simultaneously — maintaining the structural rigidity and grease-resistant containment that protect delicate salads, grain bowls, and deli preparations during storage and transit, while providing the unobstructed food visibility through a transparent window lid that converts browsing consumers into purchasing customers at the point of sale. Through over 15 years of direct supply partnerships with salad chain operators, deli distributors, convenience store prepared-food programs, and health-focused QSR brands across more than 30 export markets, we have refined every dimension of this product line — the square footprint for maximum shelf-space utilization, the PET lid clarity for true-color food presentation, the lid-to-base engagement for secure closure, and the kraft wall construction for sustained structural performance — delivering a wholesale packaging solution that simultaneously serves logistics efficiency and merchandising effectiveness at competitive factory-direct pricing across all four sizes from 500ml through 1300ml.

Key Features & Benefits
| Feature | Benefit for B2B Buyers |
|---|---|
| Crystal-clear PET window lid with high optical transparency | Enables consumers to evaluate freshness, ingredient variety, color vibrancy, and portion size before purchasing — transforming every container on the shelf into a self-merchandising display that drives impulse buying without requiring open sampling or additional signage |
| Square footprint geometry maximizes spatial efficiency | Square containers eliminate the 21.5% wasted interstitial space inherent in round-container shelf arrangements, enabling retailers to display more units per linear meter of refrigerated shelf and operators to fit more containers per delivery tray, transit crate, and shipping carton |
| 350g kraft base with PE interior coating | Delivers grease resistance and moisture barrier performance that prevents dressing migration, oil seepage, and condensation-induced base softening — maintaining structural integrity for 4–8 hours in refrigerated retail display and 45–60 minutes during delivery transit |
| Secure snap-fit lid-to-base engagement | PET lid engages the kraft base rim with consistent positive-retention closure, preventing accidental displacement during refrigerated display restocking, customer handling, bag packing, and delivery transit — while remaining consumer-friendly for easy single-hand opening |
| Four graduated sizes (500ml–1300ml) from one manufacturer | Enables buyers to source a complete salad and fresh-food container range through a single qualified supplier — eliminating multi-vendor procurement complexity, consolidating quality control, unifying brand presentation across all portion sizes, and simplifying inbound logistics |
| Natural kraft aesthetic communicates fresh and eco-conscious positioning | The unbleached brown kraft base provides an inherent visual association with natural, artisanal, and environmentally responsible food preparation — reinforcing the health-conscious brand positioning that salad restaurants, organic delis, and wellness-focused QSR chains cultivate |

| Scenario | Description | Recommended Size |
|---|---|---|
| Salad restaurant and salad bar takeaway | Dedicated salad chains, build-your-own salad bars, and fresh-food restaurants packaging custom-assembled salads with protein, grains, vegetables, dressing, and toppings for counter pickup and takeaway — requiring containers that showcase the colorful ingredient mix through the clear lid while containing dressings without leakage | 750ml (standard), 1000ml (large), 500ml (side salad) |
| Convenience store prepared-food refrigerated display | Convenience store chains merchandising pre-packaged fresh salads, fruit cups, grain bowls, and deli sides in refrigerated grab-and-go display sections where food visibility through the PET window directly determines purchase conversion rate among time-pressured commuters and office workers | 500ml (individual snack), 750ml (lunch salad) |
| Grain bowl and Buddha bowl QSR packaging | Health-focused quick-service restaurants packaging quinoa bowls, açaí bowls, Buddha bowls, poke bowls, and grain-based meal preparations with layered ingredients requiring containers deep enough for base-grain-protein-topping stratification visible through the clear lid | 1000ml (standard bowl), 1300ml (large loaded bowl) |
| Premium deli counter and gourmet food retail | Upscale delis, gourmet food shops, and specialty grocery stores packaging prepared deli salads, antipasti assortments, charcuterie portions, and premium ready-to-eat items where the kraft-and-clear-window presentation reinforces artisanal quality perception | 750ml (standard deli), 1000ml (sharing platter) |
| Bakery and pastry display packaging | Artisan bakeries, patisseries, and café pastry counters packaging individual pastries, cookie assortments, sliced cakes, and dessert portions in containers where the clear PET lid provides full product visibility while the kraft base adds warmth and craft-bakery authenticity | 500ml (individual pastry), 750ml (assortment box) |
