Barrier films are high-tech materials designed to block or reduce the passage of moisture, oxygen, light or other contaminants—extensions of shelf life and protection for sensitive products. In this category, Alte Rego provides powerful film solutions for packaging applications where preserving quality, flavor, integrity or safety is paramount (for example, meat, cheese, electronics, pharmaceuticals, or chemical products). The films’ multi‐layer construction or specialized coatings help create a durable barrier environment inside the package, enabling longer storage, safe transport and better performance under challenging conditions. Businesses using barrier films benefit from reduced spoilage, improved product safety and stronger packaging confidence—particularly in demanding supply chains.
