Large Tall Vented PET Berry Clamshell | 191×186×77mm | 50g | 400pcs/ctn | GHW-402U

QUNLU Large Tall Vented PET Berry Clamshell (Model GHW-402U) is a high-performance packaging solution engineered for modern produce packers, retailers, and growers. Building on QUNLU’s signature combination of superior clarity, protection, and stacking stability, this tall-profile PET berry clamshell offers increased depth to accommodate larger volumes or produce requiring extra vertical space. With precise dimensions of 191×186×77mm, a lightweight 50g design, and bulk packing at 400pcs/ctn, these bulk produce clamshells support efficient logistics and inventory management.

Product Features and Physical Benefits

The QUNLU PET berry clamshell is molded from high‑clarity PET, providing excellent product visibility while delivering robust impact resistance during transport and display. The taller profile (191×186×77mm) expands internal capacity, making these bulk produce clamshells ideal for large strawberries, clustered blueberries, small stone fruits (such as cherries and plums), cherry tomatoes, and delicate salad mixes that benefit from additional headroom. As a vented fruit packaging solution, the PET berry clamshell incorporates a carefully designed vent pattern that promotes air circulation and moisture control, effectively reducing condensation and slowing spoilage. Weighing only 50g, this lightweight vented fruit packaging design lowers per‑unit shipping costs while maintaining strength and ease of handling on packing lines.

Design Innovation and Handling Efficiency

QUNLU’s design team optimized the clamshell geometry of these bulk produce clamshells to balance high visibility, effective vented fruit packaging ventilation, and stacking stability. The lid and base feature a secure interlocking mechanism that protects fragile produce during handling while supporting rapid automated closure on packing lines. Vent locations in this vented fruit packaging design are engineered to maximize airflow around sensitive fruit surfaces without compromising stack strength. The taller design does not sacrifice stackability—the flat top and bottom surfaces enable multi‑layer retail displays and stable pallet stacking, reducing in‑transit shifting and simplifying store restocking.

Material Selection and Sustainability Advantages

Constructed from PET, the PET berry clamshell offers the clarity and toughness characteristic of polyethylene terephthalate, while aligning with sustainability trends in produce packaging and the demand for sustainable plastic containers. PET performs reliably in cold‑chain environments and is widely accepted in recycling streams. By choosing a recyclable material platform, QUNLU positions this product among sustainable plastic containers that meet retailer and consumer expectations for reduced environmental impact. Choosing these sustainable plastic containers with a 50g lightweight design further minimizes material usage per package, lowering transportation emissions throughout the supply chain.

Applications and Use Cases

This vented fruit packaging is well suited for strawberries, raspberries, blackberries, blueberries, as well as cherries, plums, cherry tomatoes, and delicate salad greens that require greater vertical space. Retailers benefit from the full transparency of the PET berry clamshell that enhances visual merchandising and encourages purchase. Growers and packers can leverage these bulk produce clamshells for compatibility with automated filling and labeling systems to improve throughput and traceability. Foodservice operators and farmers’ market vendors can also use these sustainable plastic containers and large‑capacity bulk produce clamshells for point‑of‑sale presentation and convenient consumer portioning

Logistics and Cost Efficiency

The 50g weight and compact dimensions of 191×186×77mm for this PET berry clamshell deliver significant logistical advantages. Lower per‑unit weight reduces freight costs and carbon footprint, while the efficient packing of bulk produce clamshells at 400pcs/ctn optimizes pallet utilization and warehouse space. When considering total landed costs—including materials, labor, shipping, and waste handling—these sustainable plastic containers offer outstanding cost‑effectiveness among large‑capacity produce packaging options. For large‑scale operations, adopting the QUNLU vented fruit packaging solution can translate into measurable savings in transportation expenses and spoilage reduction.

Visual Merchandising and Retail Appeal

Retailers aiming to showcase high‑quality produce will appreciate the fully transparent walls and secure closure of this PET berry clamshell, which enhance product presentation. The clear design of these sustainable plastic containers allows shoppers an unobstructed view of colour, texture, and ripeness, boosting consumer confidence and driving sales. The taller profile visually emphasises generous portions and premium value, making these bulk produce clamshells especially effective for premium‑tier fruit displays. The flat, low‑profile format of this vented fruit packaging is compatible with standard shelf fixtures and display trays, supporting flexible merchandising strategies.

Customisation and Branding Options

QUNLU offers customisation services for clients purchasing bulk produce clamshells who require specific branding, Barcoding, or modified vented fruit packaging patterns tailored to particular commodities or climates. Options include logo embossing on the lid or base of these sustainable plastic containers, pre‑applied food‑grade adhesive for labels, and minor dimensional adjustments for specialized product fits. These customisation options for each PET berry clamshell support marketing differentiation and supply chain traceability for packers and retailers.

① 50g — heaviest gauge in the QunLu berry range. Built for bulk capacity and stacking strength.

② 77mm height — the tallest berry clamshell in the range. Accommodates multi-layer berry fills.

③ 191×186mm near-square — maximum footprint for the largest berry count per pack.

④ Integrated micro-slot ventilation — scaled to the large surface area and tall cavity volume.

⑤ 400 pcs/ctn — bulk-format packing for wholesale and food service distribution.

All sizes available in virgin PET and GRS-certified rPET with full chain-of-custody documentation.

The 77mm height distinguishes the 402U from every other QunLu berry clamshell — it is the only format capable of holding multi-layer berry fills, making it the container of choice for bulk retail packs, food service berry portions, and wholesale formats where per-unit berry count is the primary value driver. The 50g PET gauge is proportionally reinforced to handle the structural demands of a 191×186mm span at 77mm height — thicker walls at the base and rim, optimized in the mid-body.

The near-square 191×186mm footprint provides the largest berry spread area available. Ventilation micro-slots are proportionally scaled to the 402U's large internal cavity volume — maintaining effective passive air exchange for condensation control in a container that holds significantly more produce mass than smaller formats.

Produced under the same food-grade manufacturing controls as all QunLu packaging — Class 100,000 Clean Room, individual polyolefin sleeve packaging, and batch-level QC inspection before shipment. Custom branding available via sleeve label. rPET options with GRS documentation for ESG and sustainability reporting.

The 402U's tall cavity geometry (77mm) is the most demanding thermoforming profile in QunLu's berry clamshell range — deep-draw forming at 50g gauge requires precise heating and draw control to maintain consistent wall thickness from the base floor to the rim. QunLu's KIEFEL lines are specifically calibrated for this profile.

400 pcs/ctn, 0.184 m³. Ships from Pinghu via Shanghai/Ningbo port. 77mm deep-draw — the most demanding thermoforming profile in the berry range.

Q: 402U vs 401U — how do I choose?

A: 401U (46mm height, 40g): wide flat format for single-layer display. 402U (77mm height, 50g): same footprint but tall enough for multi-layer bulk berry packs.

Q: Is the 402U suitable for food service and catering portions?

A: Yes — the 191×186×77mm volume is the largest in the QunLu berry range, suitable for bulk berry portions in food service, catering, and wholesale programs.
