Monolayer film saves ~8% but sacrifices print density and tear resistance.<\/p>\n<p style=\"margin:16px 0; line-height:1.8; color:#334155; font-size:1.02rem;\">For sustainability compliance, specify <strong style='color:#0f172a;'>minimum 30% post-consumer recycled (PCR) LDPE<\/strong>. California SB 54, Oregon, Colorado, and Maine EPR programs all penalize single-use plastic film below PCR thresholds, and the EU PPWR requires all packaging recyclable by design by 2030.
