PROTECT CALVAC 6X
Description N/A MIL-PRF-131K Type I Class I

Structure: Unprinted BON/PE/Foil/PE


PROTECT 360 is heat sealable foil that can be used for applications requiring superior tear and puncture resistance as well as protection from light, air and moisture vapor. As an added benefit, 360U conforms to FDA Regulations PART 177-1520 CFR21 for direct food contact when used as supplied and in accordance with sound manufacturing practices. DMF# 14082
N/A MIL-PRF-131K Type I Class I

Structure: OPP/PE/Foil/PE

PROTECT 470 (Marvelseal 470) meets all of the requirements of MIL-PRF-131K, Class 1. Marvelseal 470 is heat sealable and can be used for applications requiring superior tear and puncture resistance as well as protection form light, air and moisture vapor. As an added benefit, Protect conforms to FDA Regulations PART 177-1520 CFR21 for direct food contact when used as supplied and in accordance with sound manufacturing practices.
N/A MIL-PRF-131K Type I Class I

Structure: OPP/PE/Foil/PE

Meets all of the requirements of MIL-PRF-131K, Class 1. Intended for applications requiring a flexible, heat-sealable barrier material with low MVTR. FR-2175 can be fabricated into pouches and used for protection of extremely critical items and materials. DMF#14943
N/A T90 is moisture barrier packaging made with 2 layers of white film and one layer of black film with 2 layers of reinforcement. It is specifically engineered to provide high strength and durability in a lightweight material.

Moisture Barrier Packaging Features:
  • Multiple layers and cord reinforcement resist punctures and tears.
  • UV stabilization protects the material from degradation during extended exposure to sunlight.
  • Cold-crack resistance eliminates failures in cold temperatures.
  • Flexibility and light weight allow for easy handling and quick installation.
  • Custom fabrication is available to meet your exact specifications.
  • Long life expectancy allows for significant cost savings through reuse and fewer replacements.
  • Manufactured in part from environmentally recycled materials.
N/A This multi-layer laminated poly nylon film is suitable for use in vacuum packaging where moderate oxygen levels are required. Protect CALVAC 6X poly nylon film packaging performs better than coextruded film and is used primarily in the Beef, Poultry and Fish industries.
