Overview of Plastic Logistics Boxes: Plastic logistics boxes, also known as plastic turnover boxes, are made from high-impact strength HDPE (low-pressure high-density polyethylene) and PP (polypropylene).

They are formed through injection molding, mostly using a single injection process. Some plastic boxes come with matching lids (some logistics box lids are sold separately and generally fit several models of the same type of logistics box. Others are designed specifically for the same plastic box and are connected to the box body or other auxiliary parts). Additionally, some logistics boxes are designed to be foldable, reducing storage volume when empty and also lowering logistics costs for transportation. There are many specifications and shapes for plastic logistics boxes used in logistics. However, the development trend of most logistics boxes is to align with the dimensions of standard plastic pallets (for example, 600mm long × 400mm wide or 400mm long × 300mm wide). Standard-sized logistics boxes can be used in conjunction with plastic pallet sizes, facilitating unit management of products.

2 Classification of Plastic Turnover Boxes

1. Plastic logistics boxes can be classified by shape: (1) Standard logistics boxes, which are generally stackable turnover boxes, can be stacked flexibly without lid or with lid. (2) Slanted insertion logistics boxes (can be paired with inward-curved lids for use during stacking). The characteristic of this type of logistics box is that it can reduce storage volume when empty, facilitating logistics turnover costs. Note that when using this type of logistics box, a lid must be used simultaneously for stacking between two or multiple boxes. (3) Offset logistics boxes combine the advantages of standard logistics boxes and slanted insertion boxes, allowing flexible stacking of multiple boxes and enabling empty box nesting without additional auxiliary attachments, thus reducing storage volume and logistics costs when empty. 2. Plastic logistics box lids: can be flip lids or flat lids. 3. Material of plastic logistics boxes: made from high-impact strength HDPE and PP through injection molding. 4. Plastic logistics boxes can be categorized based on performance as anti-static logistics boxes and non-anti-static logistics boxes.

2.1 Function of Plastic Turnover Boxes

Turnover boxes, also known as logistics boxes, are widely used in industries such as machinery, automotive, home appliances, light industry, and electronics. They are suitable for food storage, easy to clean, facilitate convenient turnover of parts, and allow for neat stacking, which aids in management. Their reasonable design and excellent quality make them suitable for various stages in factory logistics, including transportation, distribution, storage, and processing. Turnover boxes can be combined with various logistics containers and workstations for use in various warehouses and production sites. They help achieve the standardization and integration of logistics containers, making them essential items for modern logistics management in production and distribution enterprises. Characteristics include being non-toxic, tasteless, moisture-proof, corrosion-resistant, lightweight, durable, stackable, and available in various colors. The performance of plastic turnover boxes includes resistance to bending, aging, high load-bearing strength, and they can withstand stretching, compression, tearing, and high temperatures. The colorful box-style turnover boxes can be used for both turnover and finished product packaging, lightweight, durable, and stackable. Various specifications and dimensions can be customized according to user needs, with aluminum alloy edging, covers for dust protection, and aesthetically pleasing appearance. Generally, hollow board turnover boxes are designed and manufactured based on customer-provided dimensions to achieve reasonable loading and can be stacked in multiple boxes, effectively utilizing factory space, increasing storage volume for components, and saving production costs. The 21st century is the era of environmental protection, with environmental issues becoming increasingly important and resources and energy becoming tighter. Plastic turnover boxes will face new opportunities as well as severe challenges. To meet the requirements of the new era, plastic turnover boxes are required not only to meet the increasing demands for packaging quality and efficiency in the market but also to save energy and resources. Therefore, plastic turnover boxes are developing towards high functionality, multi-functionality, environmental adaptability, using new raw materials, new processes, new equipment, and expanding application fields.

2.2 Characteristics of Plastic Turnover Boxes:

1. Colors: Blue, white, yellow, green, black, etc. Other colors can be customized starting from 200 pieces. 2. Aesthetic and Durable: Plastic turnover boxes are made from low-pressure high-density polyethylene (HDPE) through one-time injection molding, with good gloss and feel, and a long usage cycle. 3. Good Properties: Aesthetic, lightweight, anti-slip, impact-resistant, cold-resistant, heat-resistant, abrasion-resistant, pressure-resistant, corrosion-resistant, acid and alkali resistant, breathable, and waterproof. 4. High Strength: The product's structural design is reasonable, with high load-bearing strength. The load capacity of a 1L turnover box is within 1-100KG, and it can fall freely from a height of 1.5 meters without significant deformation or cracking. 5. Flammability: Flammable materials, keep away from fire sources (maximum usage temperature 100°C, ignition temperature 340°C, spontaneous combustion temperature 349°C, minimum usage temperature -25°C). 6. Good Anti-Slip: The bottom of the turnover box uses various anti-slip designs, like square reinforcing ribs, to ensure smooth operation on assembly lines. 7. Flatness: When storing items, the turnover box (logistics box) should maintain a temperature of around 40°C for optimal horizontal use; placing it on an inclined surface can cause it to tip over. Additionally, the boxes can be stacked, with the number of layers determined by the weight of each turnover box, and should not be too high to avoid deformation of the bottom box, which would affect the lifespan of the plastic turnover box (logistics box). 8. Performance and Advantages: It has properties such as acid resistance, alkali resistance, oil stain resistance, moisture-proof, pest-proof, wear-resistant, pressure-resistant, durable, impact-resistant, with no nails or sharp edges, non-toxic, tasteless, easy to wash and disinfect, non-rotting, non-polluting, economical, environmentally friendly, convenient, hygienic, safe, and recyclable. It is lightweight, smooth, has a long service life, overall good performance, aesthetically pleasing, easy to clean, neatly stackable, and easy to manage. 9. Applications: The product is suitable for high-tech electronics, hardware industries, medical fields, mechanical spare parts, refrigeration, food, aquatic products, logistics, warehousing, electronic factories, garment factories, shoe materials, toy factories, food hygiene, long-distance transportation, etc., for long-term turnover in workshops and one-time export use, meeting various needs of customers.
