Due to the excellent characteristics of plastic turnover boxes, food plastic turnover boxes still have strict technical requirements, including the following aspects:

Technical requirements for plastic turnover boxes for food

1: Appearance of plastic turnover box

Surface: complete without cracks, smooth and flat, no obvious white marks are allowed, and there are no burrs on the edges and ends.

Black spots and impurities: in each 500cm2 area of ​​each side of the box, there should be no more than 5 black spots and impurities with a length of 0.5~2.0mm, and they should be dispersed and distributed.

Color difference: no obvious color difference, the color of the same batch of products is basically the same

Gate: Does not affect the horizontal placement of the box.

Two: plastic turnover box with

Stacking coordination: Food boxes of the same specification are suitable for stacking with each other.

Anti-slip: When stacking food boxes of the same specification, no sliding is allowed.

Three: Physical properties of plastic turnover box

Bottom load-bearing: the plane deformation of the bottom of the box is not more than 10mm.

Shrinkage deformation rate: the diagonal change rate in the box is not more than 1.0%.
Drop strength: cracks are not allowed.

Stacking strength: the rate of change of the height of the box is not more than 2.0%.

Suspension strength: cracks are not allowed.
