The biggest feature of Double Berry Clamshell (12 oz) is its double-compartment partition structure, that is, one packaging box contains two independent fruit holding areas, which are separated from each other by a central partition. This design greatly improves the functionality of the packaging. It can carry fruits of different varieties or different degrees of maturity at the same time, such as packaging blueberries and raspberries together, or partitioning blueberries of the same variety by size, which helps to enrich the retail product portfolio. In addition, the partition structure can also avoid mixing and collision between fruits, keep the appearance of the goods intact, and is especially suitable for high-end fresh food markets, gift box fruit combinations, and imported fruit display sales. This type of design has been used by many brands in convenient consumer packaging in the European and American markets, reflecting the trend demand for graded fruit sales.

Double Berry Clamshell is equipped with lateral ventilation holes and slit ventilation structures to form a complete ventilation system to ensure air circulation inside the package, adjust humidity, and avoid water vapor accumulation. Through actual tests, Double Berry Clamshell can extend the shelf life of fruits by 1.5 to 2 days under cold chain conditions, significantly reducing the chance of fruit mildew and corruption. It is particularly suitable for berry products with fast respiratory metabolism such as blueberries and raspberries, which helps maintain the natural luster and firm taste of fruits. Especially in cross-border export transportation, packaging ventilation performance is one of the key indicators for evaluating freshness preservation. This design complies with international fruit and vegetable packaging standards and plays a substantial supporting role in maintaining fruit quality.

After the Single Berry Clamshell (12 oz) is upgraded to a double-grid structure, the overall box weight has slightly increased to 30 grams ± 5%, but the structural strength is more stable. The box body is made of high-quality PET raw materials with a thickness of about 0.42mm. In the top stacking load-bearing test, it can withstand a vertical pressure of more than 6kg, and the box body can be kept from deforming easily during transportation, display, and storage. This high-strength pressure-resistant design makes it widely used in high-frequency use scenarios such as batch cold chain exports and high-density placement in supermarket freezers, effectively ensuring the integrity of the packaging contents, reducing the loss rate, and improving the overall supply chain efficiency.

Double Berry Clamshell (12 oz) has reserved label pasting areas that meet international retail specifications on the cover and side, supporting barcode stickers of different sizes, brand LOGO labels, origin labels, and traceability QR codes. This design is applicable to the food traceability and product identification regulations of the US FDA, EU EFSA and other markets, and is convenient for retail terminals to use POS identification systems to manage product inventory. In addition, the box body is smooth and has no burrs or sharp corners, which improves the label sticking effect and consumer comfort. This standardized label position setting not only improves the uniformity of the product appearance, but also enhances the brand recognition ability, which helps customers create a unique visual system.

In the California factory of Driscoll’s, the largest berry brand in the United States, Double Berry Clamshell is used to load its "Berry Duet" series of products, which is an innovative combination of blueberries and raspberries for dual sales. Through the automatic packaging line, Double Berry Clamshell is pre-filled with different fruit varieties, covered with dual brand labels, and then packed and exported to North American retail channels. Its compartment design effectively avoids mixed pressure damage of fruits, and cooperates with Driscoll’s cold chain standard transportation to ensure that consumers still get the fruit as fresh as before, becoming one of its high-end composite packaging flagship products.

Double Berry Clamshell is widely used in pre-packaged fruits exported to Japan and Singapore in Hillwood Berries, a blueberry growing brand in Tasmania, Australia. Since the blueberries harvested in the region need to be packaged and entered into the cold chain within 24 hours, the high strength and ventilation performance of the packaging box become important selection criteria. Hillwood exports 12 oz double-compartment boxes of blueberries to supermarkets in many countries through vacuum pre-cooling + refrigerated transportation, reducing losses and improving packaging professionalism. This is the designated packaging form for its overseas high-end market.
