Large Flat Vented PET Berry Clamshell | 188×185×46mm | 40g | 400pcs/ctn | GHW-401U

QUNLU’s Large Flat Vented PET Berry Clamshell (Model GHW-401U) is engineered to meet the demanding needs of modern produce packers, retailers, and growers. If you are searching for high-performance PET clamshell packaging, this system provides superior visibility, protective design, and efficient handling. As a leading choice in sustainable fruit packaging, these vented PET containers deliver an optimized balance of freshness, shelf appeal, and structural strength.

Engineered Ventilation & Moisture Control

Maintaining ideal humidity is critical when packaging fresh produce, which is why berry clamshell trending formats place heavy emphasis on airflow design. The GHW-401U utilizes specialized vented PET containers featuring targeted vent patterns that promote continuous air circulation. By preventing condensation buildup, this high-grade PET clamshell packaging protects delicate fruit from premature spoilage. Choosing high-efficiency vented PET containers ensures that growers can extend product shelf life while meeting the standards of modern sustainable fruit packaging.

Premium Clarity & Merchandising Appeal

Retailers targeting high-impact shelf displays consistently prefer PET clamshell packaging for its crystal-clear visual appeal. The flat, low-profile footprint ($188 \times 185 \times 46\text{ mm}$) showcases vibrant berries and small fruits directly to consumers. Following key berry clamshell trending styles, the ultra-clear surface of these vented PET containers allows shoppers to inspect produce quality without opening the package. Furthermore, adopting sustainable fruit packaging crafted from clear PET enhances brand reputation and satisfies eco-conscious retail requirements.

Sustainable Materials & Eco-Friendly Design

Environmental impact is a top priority for produce distributors today, making sustainable fruit packaging an essential component of supply chain planning. Molded from recyclable polyethylene terephthalate, this PET clamshell packaging aligns with global recycling initiatives without compromising structural integrity. Staying ahead of berry clamshell trending practices, QUNLU engineered the GHW-401U with a lightweight 40g construction to reduce material consumption. Utilizing these lightweight vented PET containers significantly lowers transit weight, delivering true sustainable fruit packaging that lowers freight emissions across logistics networks.

Operational & Automated Line Efficiency

The GHW-401U is built for high-speed packing operations. Its rigid design allows these vented PET containers to integrate seamlessly into automated filling, closing, and labeling systems. Modern berry clamshell trending designs demand easy handling, and the secure interlocking lid on this PET clamshell packaging accelerates packing throughput while preventing accidental opens. Packers gain a reliable solution that combines automated line efficiency with the long-term benefits of sustainable fruit packaging.

Logistics Optimization & Bulk Ordering

Optimizing landed costs requires smart packaging geometry. Available in bulk configurations of 400 pcs/ctn, this PET clamshell packaging nests efficiently to maximize warehouse storage and pallet utilization. Embracing market-proven berry clamshell trending solutions helps distributors minimize damage from shifting loads during transport. By choosing QUNLU’s vented PET containers, commercial growers invest in reliable, cost-effective, and fully sustainable fruit packaging built for modern agricultural distribution.

① 188×185mm near-square — the widest flat berry clamshell in the QunLu range. Maximizes berry spread for display.

② 40g substantial gauge — heavier PET provides the rigidity needed for a 188mm-span clamshell during stacking and transport.

③ Low 46mm profile — flat shape keeps center of gravity low for shelf stability with large-format packs.

④ Integrated micro-slot ventilation — scaled to the large surface area for effective passive air exchange.

⑤ 400 pcs/ctn — large-format packing optimized for wholesale distribution.

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

The 188×185mm near-square format provides the widest flat berry display surface in the QunLu range — berries spread across a generous area, maximizing the visual impact on retail shelves and in refrigerated produce displays. The 46mm low profile keeps the overall package height compact while supporting single-layer berry arrangement; the low center of gravity provides shelf stability that taller-format containers cannot match.

The 40g gauge is the heaviest in QunLu's berry clamshell range before the tall-format 402U (50g). The additional PET weight reinforces the 188mm span against flex during filling, stacking, and transport. Hinged one-piece design with integrated micro-slot ventilation.

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 or up to 8-color UV flexo direct print. rPET options with GRS documentation for ESG and sustainability reporting.

The 401U's 188×185mm near-square geometry — wider than it is tall — requires even material distribution across both draw directions during thermoforming. QunLu's KIEFEL lines handle this through calibrated heating and draw control, maintaining consistent wall thickness across the full surface. Shared tooling platform with all QunLu berry clamshells.

400 pcs/ctn, 0.161 m³. Ships via Shanghai/Ningbo. Near-square thermoforming at 188×185mm and 40g — even draw in both directions..

Q: 401U vs 402U — which do I need?

A: 401U (188×185×46mm, 40g): wide flat format for maximum berry spread in a low-profile package. 402U (191×186×77mm, 50g): same footprint but much taller for multi-layer or bulk-fill berry packs.

Q: Is the 40g gauge necessary for this size?

A: Yes — the 188mm span requires more PET than smaller clamshells to prevent lid flex during stacking and transport. The 40g is matched to the footprint, not excessive.
