What kind of plastic will be used in different parts of plastic storage crates?

Appropriate plastic materials are selected for different parts of plastic storage crates based on their required functions and performance characteristics. Here are some common parts and the types of plastic they may be made of:

Box part:
Polyethylene (PE) or polypropylene (PP): Both plastics have good durability and impact resistance, making them suitable as the main material for the box and able to withstand the stress of daily use and handling.

Cover or sealing part:
Polyvinyl chloride (PVC) or ABS plastic: These materials have excellent water and moisture resistance, helping to ensure the storage box is airtight and prevents dust, moisture or other contaminants from entering.

Pulley or supporting part:
Engineering plastics or nylon (Nylon): These materials have high wear resistance and load-bearing capacity, and are suitable for making pulleys or support structures, making the storage box more convenient and stable when moving.

Handle or handle part:
Soft PVC or rubber (Rubber): These materials feel comfortable and have certain anti-slip properties, making it easier for users to grasp and carry the storage box.

Internal structure or separated parts:
Polypropylene (PP) or ABS plastic: These materials have good strength and stability and can be used to make partitions or support structures inside storage boxes to help users better classify and organize items.

The plastic types mentioned above are just common choices and do not mean that all plastic storage crates will use these materials. In fact, different brands and models of plastic storage crates may vary in material selection, depending on their design, use, cost, and manufacturer's preferences. Therefore, if you have specific questions about the materials used in a particular type or brand of plastic storage crates, it is recommended to consult the instructions for the relevant product or contact the manufacturer for accurate information.
