What types of materials / substrates are offered? What are their differences?

All of our biofilm materials are biodegradable with either a certified home or industrial compostability rating.

The shelf life of our materials is comparable to other alternative flexible packaging offerings assuming they are stored in a dry, room-temperature environment. If you are uncertain, we recommend testing with your product to determine if it fits your shelf life needs.

Compostable Materials:

• White - A durable option that protects against moisture, light, and oxygen, with strong puncture resistance. The solid white outer layer makes designs pop with bright, bold color.
• Thickness: 4.0 mil
• Moisture Vapor Transfer Rate (MVTR): 0.565 g/1002in/day
• Oxygen Transfer Rate (OTR): 0.019 cc/1002in/day
• Home Compostable Certified material

• Metallized - Provides solid protection from moisture, light, and oxygen, with strong puncture resistance. The metallic finish gives packaging a sleek, high-impact look.
• Thickness: 3.4 mil
• Moisture Vapor Transfer Rate (MVTR):  0.65 g/1002in/day
• Oxygen Transfer Rate (OTR): 0.03 cc/1002in/day
• Home Compostable Certified material

• Clear - A transparent option that offers good protection against moisture and oxygen. Perfect for showcasing your product with window designs. See design instructions here
• Thickness: 3.9 mil
• Moisture Vapor Transfer Rate (MVTR): 1.3 g/1002in/day
• Oxygen Transfer Rate (OTR): 0.065 cc/1002in/day
• Home Compostable Certified material

• White (Kraft) Paper – Our thickest, highest-barrier film. Resistant to oils, greases, and alcohols, with excellent gas barrier properties. Ideal for dry and fatty products. The bright white paper finish delivers a clean, premium look while staying fully compostable.

Post-Consumer Recycled Materials: (Great for all liquid, cream, or gel products)

• Metallized PCR - delivers excellent moisture, light, and oxygen barrier performance with strong puncture resistance. This structure incorporates 77% post-consumer recycled (PCR) content while maintaining the high-barrier protection required for demanding liquid and semi-liquid applications. The film can be printed in white for vibrant designs or set up to create metallized special effects for premium visual impact.
• Thickness: 4.5 mil
• Moisture Vapor Transmission Rate (MVTR): 0.06 g/100 in²/day
• Oxygen Transmission Rate (OTR): 0.07 cc/100 in²/day
• 77% post-consumer recycled (PCR) content
