Typically made of food-grade aluminium or stainless steel. Aluminium trays often require an anodized finish to prevent corrosion and surface defects. 2. Manufacturing Quality Checklist
If you are auditing a supplier or managing production, use these criteria to assess tray quality: QC Parameter Requirement Free from blowholes, cracks, shrinks, or burrs. Wall Thickness Minimum of 2mm is recommended for durability. Structural Integrity download ice tray quality control
Quality control doesn't end at purchase. Proper handling prevents bacterial growth like Legionella or Pseudomonas . Typically made of food-grade aluminium or stainless steel
Must allow for easy cube ejection (twist or flex) without stress-cracking the material. 3. Usage & Sanitation Protocol Manufacturing Quality Checklist If you are auditing a

In the food service and manufacturing industries, ice is legally classified as "food". Ensuring its safety begins with the of the trays used to freeze it. This article outlines the essential standards for ice tray manufacturing and usage, including a downloadable framework for your own QC protocols. 1. Essential Material Standards
Must be food-grade , ideally platinum-cured to resist odors and prevent leaching. In Europe, the LFGB standard is often preferred over the US FDA standard because it includes stricter migration testing.
