knowing how printing on components like this goes, I highly doubt that "TG-K-030-R" string is the batch code or lot code as some know it as. a lot code will pretty much always have a julian date in it somewhere to indicate the month and year and if not further, exact day and sometimes even time. which this code doesn't have any of that. the way that type of bag material is printed, it's going to make thousands of the same exact image, and by that I mean the entire bags image. These types of printers don't have the ability to sequentially change digits for example in a specific area of the image as each sequential component pass through the print application. applying a lot code would be one of the last things done before packing it into a shipping carton. the print for the lot code is applied typically at another production line with the bag fully assembled and sealed. TG-K-030-R is likely their SKU#. A printer like an continuous inkjet printer does have the ability to sequentially change numbers each fire, a requirement for sequentially numbering each product coming off the manufacturing line. Continuous inkjet ink looks much different from the type used to print the images on the bag material and there is no evidence of that continious inkjet type of ink/print anywhere on the bag. The numbers below the UPC barlines is the actual UPC code....which is technically an EAN barcode rather than UPC, which makes sense seeing it is sold in a region that uses that barcode type. Further proof, just google that TG-K-030-R string, a ton of sales pages pop up. It's def the SKU#/product # that the OEM Thermal Grizzly uses., NOT the lotcode.
with that said, there is zero evidence of a lot code on the bag you pictured.
to be clear, putting lot codes on products is not a requirement. but any responsible manufacture would want to in order to have traceability. any issues or complaints that come in from sellers or customers, they need to have a system to know how to trace it back to what machine produced it and when. with no lot code being applied to their sold products, they must not care about having this ability to trace issues back to the source. cannot do a recall, cannot determine if additional product in warehouses made at the same time or at the same machine could be impacted. its a bad idea all around to not have a lot code. clearly not an ISO certified company that believes in quality standards
Is there any chance they put the lot code on the actual tube of thermal grease? it would make more sense for them to put it on that tube, rather than the bag. customers are very likely going to throw the bag out immediately after opening it, which would make it hard for any customer to give info back should there be a complaint. so that is why it would make more sense to put that info on the tube that actually contains and applies the thermal grease.
