Applications

This vented PET packaging  is ideal for fresh berries strawberries, blueberries, raspberries, and blackberries—as well as small stone fruits, cherry tomatoes, and other delicate produce items. Food processors, packing houses, farmers’ market vendors, and supermarket chains will find it a practical choice for pre-packed and bulk bag replacement applications. The vented PET packaging aesthetic transparency and vented design also suit foodservice back-of-house operations that require quick visual inventory checks and hygienic storage

Design advantages and functional benefits

- Produce preservation: The venting pattern balances airflow with protective coverage, enabling respiration while limiting external contamination. This helps maintain firmness, visual appeal, and flavor profile during storage

- Enhanced shelf appeal: Clear PET maximizes color contrast and product visibility, driving impulse purchases and facilitating merchandising in refrigerated displays

- Operational efficiency: Lightweight fruit clamshells reduce per-unit freight cost and allow more units per pallet. Uniform case counts simplify replenishment cycles and reduce handling complexity at distribution centers

- Brand clarity: The smooth, printable surfaces of  allow for high-resolution labeling, bar-coding, and custom brand messaging without compromising transparency. Retailers and co-packers can apply stickers or sleeves for promotional campaigns and traceability

Innovation and technical strengths

QUNLU’s Large Vented PET Berry Clamshell applies precise injection molding techniques and optimized vent placement to deliver a package that is both breathable and structurally sound. The vented PET packaging company’s tooling expertise ensures consistent wall thickness for impact resistance at a remarkably low part weight. This vented PET packaging combination of molding precision and design intelligence results in a product that performs reliably in cold chain environments and under common retail handling stresses

Venting technology: The vent aperture geometry is engineered to create laminar airflow around the produce, minimizing stagnation zones where moisture can accumulate. This vented PET packaging improves evaporative moisture loss control and reduces microbial growth points without exposing fruit to excessive external contaminants

Material selection and sustainability: The use of vented PET packaging provides excellent optical clarity and a high recycled stream potential. The lightweight fruit vented PET packaging contribute to lower material consumption per unit and reduced carbon footprint in transport. QUNLU’s manufacturing process supports recyclable resin use and can be adapted to incorporate post-consumer recycled content where required by customers

Retail merchandising and convenience

Retailers benefit from the vented PET packaging stack-and-display capability, which facilitates eye-catching produce islands and refrigerated shelf layouts. The transparency and shallow depth display fruit attractively while optimizing vertical shelf space. Lightweight fruit vented PET packaging increase shelf facings per case and enable faster restocking

Customization and supply options

QUNLU offers private-label and OEM options to meet brand specifications, including color tints, bespoke die-cut vent patterns, and print-ready surfaces for pressure-sensitive labels or shrink sleeves. Standard packaging quantities such as 600pcs/ctn facilitate planning, but QUNLU vented PET packaging can adapt carton counts and pallet configurations to customer logistics needs

Quality control and regulatory compliance

Manufactured under stringent quality systems, the vented PET packaging conforms to food-contact safety standards applicable in major markets. QUNLU’s production includes dimensional verification, material traceability, and cleanliness protocols to ensure compliance and reduce risk in food packaging operations

① Largest footprint — 157×139mm. Maximum berry count per pack for family-size and wholesale.

② 22g structural weight — heavier gauge than 125A, reinforced for the larger span.

③ Flat base only — simple configuration maximizing fill volume. No trade-off with presentation options.

④ Integrated micro-slot ventilation — passive air exchange for condensation control on retail shelves.

⑤ Hinged one-piece — one-motion close. 600 pcs/ctn for distribution efficiency.

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

At 157×139mm, the GHW-185A provides the largest fill area in QunLu's berry range — accommodating a higher berry count per pack for family-size retail and wholesale formats. The 22g gauge reinforces the larger span during filling and transport. Ventilation slots are molded during thermoforming, proportionally scaled for the larger surface area.

The single flat base configuration keeps the product simple — no convex option means no trade-off between fill capacity and visual presentation. Designed for value-oriented programs where volume per pack drives the consumer decision. Hinged design compatible with manual and semi-automated packing lines. The 157×139mm rectangular format is the go-to for family-size and club-store berry packs where volume-per-unit supports a higher retail price point.
