This solution it's work for me

private function addAltChunk($refID, $addPageBreak)
	{
		$pagebreak = $addPageBreak ? '<w:p><w:pPr><w:sectPr><w:type w:val="nextPage" /></w:sectPr></w:pPr></w:p>' : ''; //'<w:p><w:r><w:br w:type="page" /></w:r></w:p>' : '';
		$xmlItem = $pagebreak . '<w:altChunk r:id="' . $refID . '"/>';

		$p = strpos($this->docxDocument, '</w:body>');
		$this->docxDocument = substr_replace($this->docxDocument, $xmlItem, $p, 0);
	}
