Where Are PP Hollow Sheet Vegetable Boxes Used?
PP hollow sheet vegetable boxes are environmentally friendly packaging containers widely used in modern agriculture, fruit and vegetable harvesting, cold chain transportation, and warehousing. They are made from non-toxic and odorless PP (polypropylene) raw materials into hollow sheets through extrusion molding, and then fabricated into boxes via die-cutting, folding, riveting, or ultrasonic welding.
Core advantages
Waterproof, moisture-proof, and breathable for freshness: Unlike traditional cardboard boxes, PP hollow sheets offer excellent water and moisture resistance, preventing softening or deformation in humid or cold chain environments. The hollow structure and customizable ventilation holes allow proper airflow for fruits and vegetables, effectively maintaining freshness and reducing loss.
Lightweight yet strong and durable: The material is light in weight, but its unique hollow structure provides high compressive strength and toughness. It can bear tens of kilograms without deformation and is resistant to cracking during transportation and handling.
Eco-friendly, reusable, and cost-effective: The boxes are foldable and reusable for multiple cycles, and can be recycled after disposal. This eliminates the high costs and resource waste associated with single-use cardboard boxes.
Safe, non-toxic, and available in various colors: Made from food-grade virgin PP material, they are non-toxic and odorless, suitable for direct contact with fresh produce. Colors can be customized by adding masterbatch (such as blue, yellow, green, and red) for easy classification of different types of fruits and vegetables.
Application scenarios
Fruit and vegetable harvesting and sorting: Used for on-site harvesting, temporary loading, and origin sorting in vegetable greenhouses and orchards.
Cold chain transportation and circulation: Suitable for long-distance cold chain transport, wholesale market circulation, and supermarket delivery of perishable produce such as leafy vegetables, asparagus, okra, and grapes.
Warehousing and shelf storage: Sizes can be customized for easy palletizing and efficient use of warehouse space. Some models are designed with reinforced tabs to prevent slipping during stacking.
