The legislation will also ban temporary price drops and multi-buy offers on unhealthy foods.
The restrictions will be placed on certain combinations that have a high fat, sugar, or salt content above the recommended daily amount.
The legislation will be rolled out across Wales in 2025 and will apply to all businesses employing more than 50 people.
Retailers have raised concerns about the timing of the announcement as food prices remain high.
However, the Welsh government says there is strong public support for action to help people make healthier food choices and that the aim is to rebalance food environments towards healthier products.
The Welsh government has announced plans to tackle obesity by introducing a "tax on sugary drinks, a levy on junk food and a ban on the sale of energy drinks to children".
However, there are concerns that these measures could increase the cost of living for shoppers.
James Evans, a Welsh Conservative spokesman for mental health, has said that promotions within categories allow retailers and brands to compete and keep prices down.
Plaid Cymru supports measures that make it easier to choose healthy lifestyle options, but wants to find a balance between preventing poor health and restricting households that are already facing budget constraints.
