Durable white polypropylene (PP) blister trays represent a mainstream choice in the food packaging sector, offering a perfect blend of durability, safety, and cost-effectiveness. In particular, the three-compartment and four-compartment PP mooncake trays are classic staples for Mid-Autumn Festival food packaging.

I. Core Materials and Performance

Manufactured from food-grade polypropylene via a vacuum thermoforming process, white PP blister trays offer a multitude of advantages:

Safe and Non-toxic: Compliant with food- contact standards, free from plasticizers and odors, allowing for direct contact with food items such as mooncakes and pastries.

Durable and Robust: Possessing high toughness and impact resistance, they are resistant to cracking and breakage, capable of withstanding the pressures of transportation and stacking, making them suitable for repeated handling and circulation.

Wide Temperature Range: Capable of withstanding temperatures ranging from -20°C to 120°C; they are suitable for both refrigeration and microwave heating, meeting the specific storage and reheating requirements of mooncakes.

Moisture-proof and Dust-proof: Offering excellent barrier properties, they effectively protect mooncakes from moisture and flavor contamination, thereby extending their shelf life.

Eco-friendly and Recyclable: The PP material is fully recyclable, aligning perfectly with current trends in sustainable and eco-friendly packaging.

II. Design and Application of Three- and Four-Compartment PP Mooncake Trays

The three- and four-compartment configurations represent the most popular specifications for mooncake packaging, designed to integrate seamlessly into Mid-Autumn Festival gift box presentations:

Three-Compartment Trays: Typically sized to accommodate mooncakes weighing between 50g and 80g, each tray holds three pieces. Ideal for smaller gift sets and souvenirs, this design features a compact structure that maximizes space efficiency.

Four-Compartment Trays: Designed to fit standard-sized mooncakes weighing between 80g and 120g, each tray holds four pieces. This is the preferred choice for family-sized packs and standard gift boxes, featuring clearly defined compartments and a neat, organized layout that enhances the overall premium feel of the gift box.

Craftsmanship and Customization: Produced using advanced thermoforming techniques, the trays feature precise mold shaping and smooth, burr-free edges. Customization options—including thickness (ranging from 0.3mm to 0.8mm), logo printing, and hot stamping—are available to meet specific brand packaging requirements.

III. Applicable Scenarios and Key Advantages

Mooncake Packaging: Three- and four-compartment PP trays serve as the essential internal inserts for Mid-Autumn Festival mooncake gift boxes, securely holding the mooncakes in place, preventing collision damage, and elevating the perceived quality and sophistication of the gift packaging. Pastry & Dessert Packaging: Suitable for items such as yolk pastries, mung bean cakes, and cookies; features a compartmentalized design to prevent food from sticking together or intermingling flavors.

Pie & Tart Packaging: White PP trays designed for baked goods like pies and egg tarts; heat-resistant and facilitates easy demolding, making them ideal for integration into commercial baking production lines.

Logistics & Storage: The trays are stackable and lightweight, helping to reduce transportation costs while being well-suited for both e-commerce shipping and supermarket warehousing environments.
