Technical Specifications for PEAKfresh USA
​Modified Atmosphere Packaging

Properties: PEAKfresh is a treated natural mineral that is impregnated into low density polyethylene resin to produce a packaging film. The impregnated mineral is hydroscopic and has permeability characteristics. When used with refrigeration at the correct temperatures levels, PEAKfresh will extend the life of your product.

PEAKfresh Film Features:
- Excellent permeability to gases
- Good food deodorizing properties
- Removes ethylene gas
- Anti-fog treatment to reduce water formation
- Maintenance of high humidity levels to limit produce weight loss
- Gauge variation to increase permeability
- Cost effective compared to normal plastic
- Good active surface area to volume ratio
Permeability: 4.5 times greater permeability than standard LDPE at 71.6°C
Application: Carton liners, pallet covers and bulk bin liners, flat and gusseted bags, sheets and roll stock
Anti-fog: Yes
Gauge: Available in mil and microns
Oxygen Transmission Rate: Nominal 23000-24000 cc/M2 /24 hours at 71.6°F (*1)
Carbon Dioxide Transmission Rate: Nominal 23000-24000 cc/M2 /24 hours at 71.6°F (*1)
Water Vapor Transmission Rate: Nominal  25-27 grams per square meter
Ethylene Removal Rate: Nominal 3900 cc/M2 /24 hours at 71.6°F (*2)
PEAKfresh is approved for Organic packaging by OMRI (code:pfp-2278). This listing indicates that PEAKfresh produce bags comply with OMRI policy and Standards Manual, which is based on the requirements of the USDA National Organic Program Rule (7 CFR part 205)
(*1) Gas permeability values vary slightly as a result of mineral impregnation and porosity of the mineral and minute tears to the film at the point of mineral impregnation. The density of LDPE used also has an effect on permeability
(*2) The measurement was made using a 1.61ppm ethylene/air mixture.
