For Class 16 trademarks, whether they can be printed on plastic bags for promotion depends on two situations.
First, among the 16 categories, there is the product item "plastic bags". If your registered trademark has approved the product item "plastic bag", or approved other product items similar to the product "plastic bag". It can be printed directly on plastic bags for promotion.
Second, if when applying for a registered trademark, the product item "plastic bag" is not filled in, or other products similar to "plastic bag" are not filled in, or the product is declared, but the product The item was not approved.
When printing on plastic bags for promotion, special attention should be paid to not just writing your trademark name, which may easily lead the public to mistake it for a "XX" brand plastic bag, while "plastic bag" This product item has not been declared or has not been approved. In this case, you will be punished.
It is also easy to infringe. Suppose someone else registers the product item "plastic bag" with the same or similar name as your trademark in Category 16, you will be infringed.
So, in the second case, the brand name should be printed on the plastic bag, and then the product to be promoted should be added.
For example, "such-and-such pencil" and "such-and-such pencil".
When the public sees it, they will think that you are promoting pencils, not plastic bags.
Finally, if you just submit your trademark registration application to the Trademark Office, it has not yet been approved. You want to add the TM promotional trademark on the plastic bag.
I don’t recommend doing this. First of all, this TM has no legal effect. Moreover, you did a lot of publicity in the early stage, but in the end your trademark was not approved, so your publicity was in vain.
