The GHW-125B is the compact, lightweight counterpart to the GHW-125A in QunLu's ventilated berry packaging range — purpose-built for single-serving retail packs, convenience store formats, and cost-sensitive produce programs where smaller portion size and lower packaging cost are the primary requirements.
At 105×108mm rectangular and just 10g per unit, it delivers 40% material savings over the 125A while maintaining the same flat/convex base flexibility and integrated micro-slot ventilation. The rectangular footprint packs more facings per linear meter on supermarket shelves — a display density advantage over square formats. Each pack holds approximately 125g of berries. The lightest hinged clamshell in the QunLu berry range — 10g, engineered for single-serving economics.

QUNLU presents the Lightweight Vented PET Berry Punnet | Flat & Convex Base | 105×108×40mm | 10g | GHW-125B, a purpose-built berry Punnet designed for modern produce packing lines and retail displays. This vented PET Punnet solution redefines how small fruit is handled, stored, shipped, and merchandised. As a leading lightweight berry Punnet option, the GHW-125B merges practicality with innovation to meet the evolving needs of growers, packers, retailers, and sustainability-minded brands
The QUNLU GHW-125B berry Punnet is crafted from high-clarity polyethylene terephthalate, delivering a lightweight profile at just 10g while maintaining structural integrity. This berry Punnet features a vented PET Punnet design to maximize airflow and prolong shelf life. The flat and convex base clamshell form factor provides two reliable base options: a stable flat base for stacked handling and a convex base for enhanced product presentation. Measuring 105×108×40mm, this vented PET Punnet accommodates a standard retail portion of berries with a compact footprint, making it a versatile solution across packing lines and point-of-sale displays
Constructed from food-grade PET, this vented PET Punnet combines clarity, stiffness, and recycle ability. The vented PET Punnet pattern is engineered to promote air circulation around soft fruit, reducing moisture accumulation and minimizing spoilage. QUNLU’s selection of PET ensures the berry Punnet sustains impact resistance while remaining lightweight, delivering tangible cost savings in transport and handling
- Vented PET packaging vents: Strategic vent placement in this berry Punnet accelerates respiration control for perishable fruit, helping preserve texture and flavor. - Lightweight construction: At 10g, the berry Punnet reduces material use and lowers freight energy consumption. - Flat and convex base clamshell versatility: The dual-base approach offers stacking stability and attractive product elevation in retail displays. - Compact dimensions: The 105×108×40mm body optimizes retail shelf density and packing efficiency. - Recyclable PET: The Punnet supports established recycling streams, aligning with sustainable fruit packaging goals
This vented PET Punnet solution is ideal for berries, small stone fruit, and delicate produce such as strawberries, blueberries, raspberries, and blackberries. Growers can use the QUNLU vented PET Punnet to pack harvests directly at the field packing site or in centralized packing houses. Retailers benefit from the clarity of the vented PET Punnet to present fresh produce attractively while relying on the flat and convex base clamshell for ease of shelving and merchandising. E-commerce grocers and meal-kit providers can also incorporate this lightweight berry Punnet to reduce shipping costs and protect fruit during transit
The vented PET Punnet layout in this berry Punnet reduces internal humidity and permits ethylene exchange, thereby slowing deterioration and extending shelf life. By choosing a lightweight berry Punnet, suppliers reduce per-unit material and transportation costs without sacrificing strength. The flat and convex base clamshell delivers mechanical stability during stacking and handling, while the convex option lifts fruit for improved visibility, increasing purchase likelihood at retail. The vented PET Punnet material provides dimensional stability, resisting warpage and maintaining consistent performance across temperature variations encountered from cold storage to ambient retail environments
QUNLU designed this vented PET Punnet with sustainability in mind. The vented PET Punnet low-weight construction minimizes plastic usage per unit, decreasing embodied carbon across large-volume shipments. The vented PET Punnet resin is recyclable in many regions, supporting circularity when consumers and waste managers follow local recycling practices. By combining lightweight design with a recyclable material, the berry Punnet addresses the dual goals of reducing waste and maintaining protective performance—key elements in sustainable fruit packaging strategies
QUNLU offers customization options for the berry Punnet to align packaging with brand identity and functional requirements. The vented PET Punnet can be tailored with printing options, labeling recesses, or tamper-evident seals. Retailers can choose between a flat and convex base clamshell orientation to match display plans, while packers can specify lid or base modifications to integrate with automated packing equipment. These options help brands communicate quality and enhance shelf impact while retaining the logistical advantages of a lightweight berry Punnet
The GHW-125B berry Punnet is compatible with high-speed filling lines and manual packing stations. The vented PET Punnet packaging design minimizes clumping and condensation, aiding consistent fill weights and reducing select-and-pack errors. The flat and convex base clamshell geometry allows efficient nesting for transportation and storage before use, improving pack house ergonomics. When stacked, the lightweight berry Punnet balances durability and reduced weight, enabling more units per pallet and lower shipping costs
QUNLU manufactures the vented PET Punnet under stringent quality controls and food safety standards. The vented PET Punnet is food-contact safe and processed to eliminate contaminants while preserving transparency and physical properties. The berry Punnet’s structural features undergo durability testing to ensure reliable performance through distribution cycles. Compliance with applicable regulations and traceability practices gives packers and retailers confidence in product safety
① Flat or convex base — same lid, two fill depths. Flat base for value packs targeting maximum berry count; convex base for premium packs where fewer berries are spread across a wider visual surface.
② 10g — 40% lighter than the 125A. The lowest per-unit material weight in the QunLu berry clamshell range, directly translating to lower procurement cost and reduced inbound freight weight at container volume.
③ 105×108mm rectangular format — the narrower width allows tighter shelf packing than square formats, maximizing product facings per linear meter in refrigerated produce displays.
④ Integrated micro-slot ventilation — same passive air-exchange design as the 125A. Vents molded during thermoforming.
⑤ Hinged one-piece clamshell — close with a single folding motion. 1,000 pcs/ctn in a compact 53×45×54.5 cm carton for efficient distribution and warehouse handling.
All sizes available in virgin PET and GRS-certified rPET with full chain-of-custody documentation.

Q: GHW-125B vs GHW-125A — how do I choose?
A: 125B is the compact format (105×108mm rectangular, 10g, ~125g capacity) for single-serving packs and convenience store programs. 125A is the larger standard format (125×125mm square, 16.5g) for full-count retail packs. Both offer the same flat/convex base system and micro-slot ventilation design.
Q: Is a 10g clamshell durable enough for transport and retail stacking?
A: Yes. The weight reduction is through wall thickness optimization, not structural compromise. The living hinge, ribbed base sidewalls, and snap-lock closure function identically to heavier clamshells in the QunLu berry range. The ventilation slots are sized to contain all standard small-berry varieties without product escape.
Q: Can I order 125A and 125B mixed in the same shipment?
A: Yes — both sizes share the same ventilated clamshell tooling platform. They can be co-produced in a single run and co-shipped in one container. Specify your 125A and 125B quantities separately when requesting a quote; any ratio is supported.
