Please check the production conditions asap ka. if you look at below pictures you can see that the one for TH (left side) has more distortion (ถาดบิดงอค่อนข้างมาก) while Indo tray does not seem to have much effect of the issue.
We can see clearly of bending tray when open from pack. Please investigate and let me know root cause and solution ka. We will not accept tray with bending like in the picture. Please provide standard with -/+ percentage for acceptance.
