May one tear open the wrapping of a pack of plastic plates on shabbos if one has regular dishes but prefers to use plastic
It is permitted to rip open the wrapping on the plastic plates etc., even if you aren’t stuck, without any problem. The reason is because these wrappings are there only as a one-time covering, until the product is ready to be used, and it was never considered a vessel, therefore breaking it isn’t a problem. It is preferred however that it be opened in a way that ruins it, that it cannot be used as a receptacle, Also be careful not to rip any letters or pictures, because of mochaik ( erasing).
