Baolima strictly controls the quality of folding turnover boxes. For folding boxes, collapsible boxes, and large folding turnover box products, we have a standard and complete inspection to ensure the quality of folding turnover boxes.
Baolima’s folding turnover box time production plan:
Baolima will conduct large-scale pre production inspections on folding turnover boxes. Before mass production of the product, Baolima will conduct a 2-hour test on the mold to ensure stable operation and durability of the plastic material. Then, Baolima Holdings Group will use 10 folding turnover boxes for testing. If these 10 samples pass the test, we will put them into production.

Testing of Baolima folding turnover boxes before mass production:
Before mass production, Baolima will take one of the samples to test its surface quality and conduct a series of tests. If any problems occur, Baolima will immediately stop mass production, inspect every step and find a solution to the problem, until Baolima samples pass all tests and inspections before we can resume production. After mass production, Baolima Holdings will conduct another inspection report to identify all issues, and our employees will repeatedly check the production line of folding turnover boxes.
Pre shipment inspection of Baolima folding turnover box:
Baolima will inspect the surface quality and packaging of the folding turnover boxes before shipment to ensure that they meet our standards and satisfy our customers.
Inspection points for Baolima turnover boxes:
- Size monitoring of folding turnover boxes
The size monitoring of the folding turnover box will directly affect the folding of the folding turnover box, and a slight impact on size can lead to space waste. Therefore, we have strict requirements for the raw materials of the folding turnover box. To ensure the size of the turnover box, we will repair and inspect every dimension of the turnover box mold.
- Folding turnover box stacking detection
The bottom and lid of the folding turnover box are quite close and can maintain a straight line. When 50 folding turnover boxes are stacked together, or when 15KG of items are placed on the turnover box, it will not tilt at all. When we increase the foot height by 2CM at the bottom of the turnover box, they will not slip.
- Compression performance testing of foldable boxes
We pack each folding turnover box into 15 kilograms of items, stack them onto 10 folding turnover boxes, and maintain them for 24 hours without the bottom turnover box deforming.
- Folding box drop test
We pack each folding turnover box with 15 kilograms of items, cover it, and drop it from a height of 3 meters without damaging the contents inside.
The turnover boxes provided by Baolima to customers around the world are all quality guaranteed, and our turnover boxes fully meet the above testing requirements. Each folding turnover box has undergone the strict testing mentioned above. Baolima employees are dedicated and responsible, and will ensure the satisfaction of our esteemed customers.
