It may also come from condensation if warm product is sealed before it has cooled under controlled conditions.<\/p>\n    <p>For this reason, a packaging complaint should not begin with the pouch alone. Buyers should review the condition of the product before filling, the package barrier and seal, the route to market and the way the pack is stored after arrival.<\/p>\n    <div style=\"padding:18px;border-left:4px solid #8a5a2f;background:#fff8f0;\"><strong>Important:<\/strong> A high-barrier film cannot repair chips that were already soft, too warm or outside the agreed condition when packed.
