Hey there, if you\u2019ve ever shipped or handled glass trays, you know that even a tiny scratch can turn a perfect batch into something unfit for use. As a tray supplier, I\u2019ve seen firsthand how preventable scratches are\u2014most people just don\u2019t know the right tricks to keep their glass trays safe. I\u2019m gonna break down the science (no boring jargon, promise) and the actual steps we\u2019ve tested with our clients over the years, so you don\u2019t end up tossing trays that should last forever. Tray<\/a><\/p>\n

<\/p>\n

First, let\u2019s get one thing straight: scratches don\u2019t just \u201chappen.\u201d They\u2019re almost always from three culprits: hard surface contact, abrasive particles, and improper stacking. I remember a client last year who was stacking 12 glass trays on top of each other with only a single sheet of thin paper between them\u2014by the time they arrived at the warehouse, 18% had deep scratches that made them useless for food service. That\u2019s a avoidable loss, right? Let\u2019s dig into the real fixes.<\/p>\n

1. Know the enemy: What actually scratches glass?<\/h3>\n

Glass is way tougher than you think\u2014most standard soda-lime glass (the kind we use for our trays) has a Mohs hardness of around 5.5. For reference, fingernails are 2.5, aluminum foil is 3, and stainless steel is 4.5. Wait, so why do steel tools scratch it? Because steel has tiny, sharp metal particles that can act like little knives when pressed hard enough. Even something you\u2019d think is soft, like a wooden shelf, can have hidden grit (dust, food crumbs, small gravel particles) that\u2019s Mohs 7 or higher\u2014those will carve into glass way faster. That\u2019s the science bit: a scratch forms when a particle harder than glass gets dragged across its surface with enough force to remove a tiny sliver of glass.<\/p>\n

So first, stop treating glass like it\u2019s indestructible. I\u2019ve had new customers say \u201cwe always just stack them loose, no problem\u201d until their first shipment comes back with a pile of damaged trays. Don\u2019t be that person.<\/p>\n

2. The #1 fix: Use the right separating materials<\/h3>\n

This is the trick that makes 90% of scratch problems go away. Most people grab whatever\u2019s lying around\u2014old newspaper, thin paper towels, even a flimsy sheet of cardboard. But those don\u2019t work. Let\u2019s break down what does work, and what to skip:<\/p>\n
