Plastic containers are lightweight, high-strength, non-toxic, non-polluting, waterproof, moisture-proof, resistant to acid and alkali corrosion, and oil stains, with a rich color range. They possess excellent environmental performance and recyclability, making them a new type of environmentally friendly packaging material widely adopted by many advanced countries. Unlike most plastic packaging materials, which are typically disposable, plastic containers are often recycled and reused multiple times. Therefore, in addition to ensuring good protection and storage for the contents during use, their design also needs to consider the stacking of empty boxes to save storage space and reduce transportation costs. The design of plastic containers usually includes clips, allowing boxes of the same length and width to be stacked conveniently. Folding boxes can also be collapsed during storage, saving considerable space. The transportation time for sending goods out and bringing empty boxes back can also save a lot of space. The production of plastic containers is also quite fast, with an average medium-sized box taking about 50 seconds to produce.
