Stop losing premium produce to bruising, condensation mold, and leaky packaging. At HSQY, we manufacture high-performance PET Clamshell Containers engineered specifically for the rigorous demands of the fresh produce cold chain. Combining glass-like optical clarity with robust structural integrity, our one-piece hinged containers protect delicate fruits from physical damage while maximizing retail shelf appeal and driving impulse purchases.
Whether you require strategic airflow management for highly respiring berries or leak-resistant containment for fresh-cut fruits, our specialized designs ensure optimal shelf life. Backed by our vertically integrated manufacturing facilities, HSQY guarantees precise dimensional consistency, secure snap-lock closures, and reliable bulk supply in both virgin PET and sustainable rPET materials for global supermarket chains and packing houses.
Strategic Airflow & Moisture Management: Our ventilated models feature precision-engineered multi-hole patterns that promote optimal airflow, drastically reducing condensation buildup and preventing the mold growth that rapidly destroys delicate berries.
Top-Load Stackability & Bruise Protection: Engineered with reinforced structural ribs and high-rigidity walls, our clamshells withstand the heavy top-load pressures of cold-chain logistics and retail stacking, ensuring the fruit inside remains completely unbruised.
Leak-Resistant & Secure Snap-Lock: For fresh-cut and high-moisture fruits, our specialized models feature slightly raised edges and secure integral snap-lock closures to contain juices and prevent messy leaks during transit and display.
Optical Clarity & rPET Sustainability: Our crystal-clear PET showcases produce freshness to boost sales. To support your ESG and circular economy goals, we offer 100% recyclable #1 PET and post-consumer rPET options that maintain the same high-clarity and structural performance.
Fresh Berry Packing: The mandatory choice for strawberries, blueberries, raspberries, and blackberries at farms and packing houses, utilizing ventilation to extend shelf life.
Supermarket Produce Aisles: High-visibility packaging for pre-packed grapes, cherry tomatoes, and exotic fruits, enhancing the premium perception of the produce.
Fresh-Cut & Meal Kits: Leak-resistant designs perfectly suited for sliced apples, melon cubes, and salad ingredients in meal kit delivery services.
Farmers' Markets & Local Farms: Durable, easy-to-open hinged containers that elevate the professional appeal of locally grown, direct-to-consumer produce.
Material: 100% Food-Grade PET or rPET (Recycled PET)
Temperature Resistance: -20°C to +70°C (Optimized for Cold Chain & Room Temperature Display)
Form Factor: One-piece hinged clamshell with integral snap-lock closure
Ventilation: Optional multi-hole patterns for moisture management
Certifications: FDA, SGS Compliant, BPA-Free, 100% Recyclable (#1 PET)
*Safety Note: While resistant up to 70°C, these containers are strictly designed for cold-chain and display use. They are NOT suitable for microwave heating or high-heat cooking.
PET-VC-01 (Ventilated Berry Clamshell): 250g capacity (6" punnet style). Specifically engineered for fresh berries with a multi-hole ventilation pattern to reduce moisture, prevent crushing, and extend shelf life.
PET-FT-01 (High-Strength Clear Tray): 500ml capacity. Features a leak-resistant design and reinforced walls, ideal for general supermarket fruits, fresh-cut fruits, and premium gift packaging.
Custom Tooling: Bespoke mold development for unique produce shapes, custom capacities, and specific ventilation requirements.
Selecting the correct clamshell is critical for preventing spoilage and physical damage. Our engineers will help you define:
Respiration & Moisture Profiling: Matching the ventilation pattern to the specific respiration rate of your produce (e.g., high ventilation for berries vs. sealed containment for cut melons).
Top-Load & Stacking Requirements: Calculating the necessary structural ribbing to ensure the containers can be safely palletized and stacked in retail displays without collapsing.
Sustainability Mandates: Navigating local retail requirements to determine if standard virgin PET or post-consumer rPET is required for your target market.
Q1: What is the exact difference between the PET-FT-01 and PET-VC-01 models?
A: The PET-VC-01 is a 250g ventilated clamshell specifically engineered for highly respiring berries (like strawberries and blueberries). Its multi-hole pattern promotes airflow to prevent condensation and mold. The PET-FT-01 is a 500ml high-strength tray with a leak-resistant design, optimized for general fruits, fresh-cut fruits, and products where juice containment is more critical than ventilation.
Q2: How do the ventilation holes actually extend the shelf life of berries?
A: Berries continue to respire and release moisture after harvesting. In a sealed container, this moisture condenses on the plastic walls and the fruit, creating the perfect environment for rapid mold growth and rotting. Our precision-engineered ventilation holes allow this excess moisture and ethylene gas to escape while maintaining the cold-chain temperature, drastically reducing spoilage and extending retail shelf life.
Q3: Can these clamshells withstand stacking in cold storage and transport?
A: Yes. Physical bruising and crushing are major causes of produce loss. HSQY clamshells are engineered with reinforced structural ribs, secure snap-lock closures, and high-rigidity PET walls. This provides exceptional top-load strength, allowing the containers to be safely stacked in cartons, on pallets, and in supermarket displays without collapsing and damaging the fruit inside.
Q4: Are these containers safe for acidic fruits and fully recyclable?
A: Absolutely. Our containers are manufactured from 100% food-grade PET, which is completely BPA-free, non-toxic, and chemically resistant to the natural acids found in fruits like berries and citrus. Furthermore, PET is classified as #1 plastic, making it the most widely accepted and recycled polymer globally. We also offer rPET options to support your brand's sustainability initiatives.
Q5: What is your MOQ and do you support custom mold development?
A: For standard stock molds (like the VC-01 and FT-01), our MOQ typically starts from 20,000 to 50,000 pieces to ensure manufacturing efficiency, with a standard lead time of 15-20 days. We fully support custom mold development for unique produce shapes, custom capacities, and specific ventilation patterns. Free samples are always available for your packing line and cold-chain validation testing.
