Foil

Aluminum foil is perhaps the most versatile packaging material on the market today. No other material can claim to be the lowest-cost absolute barrier to light, moisture, and oxygen. Laminated to paper or plastic films for strength, foil provides lighter, less-expensive protection to foods, medicines, and other products that might be damaged by the environment. Here are some of the characteristics of foil that make it so useful:

• Formable: Superior dead-fold characteristics for good performance on high-speed packaging lines
• Corrosion Resistant: Natural oxide coating reduces corrosion
• Impermeable: 0.001-inch foil and thicker is impermeable to moisture and oxygen; 0.00035-inch foil has a water vapor transmission rate of 0.02 grams or less per 100 square inches; vapor transmission drops to zero when 0.00035-inch foil is laminated to an appropriate film
• Adaptable: Can be combined with virtually any other flexible packaging material
• Not Absorbent: Will not absorb water or other liquids
• Opaque: Transmits no light
• Sealable: Excellent dead-fold and adhesion to a wide variety of compounds
• Non-Soluble: Will not combine with foods and other substances
• Tasteless, Odorless: Imparts no detectable taste or odor to products
• Hygienic: Sterile when heat-treated in production. Smooth metallic surface sheds most of the contaminants and moisture of sterilization
• Non-Magnetic: Provides excellent non-magnetic shielding
• Good Conductor: Good for sealing by heat and induction
• Great In the Kitchen: Foil Containers Now Microwaveable
