The ban, set to take effect on September 1, would apply to all public and private primary schools during classes, breaks and off-campus educational activities.
School trips and dormitory stays would be exempt, with individual schools setting their own rules for those settings.
Exceptions would be permitted when a teacher authorizes device use for educational purposes, when a student needs to contact a parent in an emergency, or when a school principal grants a temporary exemption due to a student's health condition or disability.
Schools would enforce the ban through disciplinary measures including warnings, behavioral contracts and grade penalties.
Secondary schools would be allowed, though not required, to adopt similar restrictions through their own statutes.
Education Minister Barbara Nowacka said the measure responds to widespread demand from educators.
"They need a law they can refer to", she said on Tuesday, noting the ban already applies in more than half of Polish schools and that surveys show 85 percent of the public supports it.
Nowacka urged parents to monitor their children's phone use at home, saying research shows excessive use typically occurs after school hours.
"The real problem begins after 4 p.m., when children come home," she said.
Schools will have until October 31 to update their internal regulations.
The ministry said the measure is part of a broader digital education policy, which also includes strengthened curricula on digital hygiene and media literacy.
