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 known absorption characteristics.

PEAKfresh® Film features:

• Excellent permeability to gases.
• Good food deodorizing properties.
• Removes ethylene gas and has some minimal absorption capacity.
• 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.

PEAKfresh® helps maintain vitamin C Levels:
Using PEAKfresh® SAVES YOU MONEY by extending the freshness and shelf life of the floral and produce items.

Permeability: 4.5 time’s greater permeability than standard LDPE at 22°C.

Application: roll stock, carton liners, flat bags, sheets, pallet liners and covers.

Anti-fog: yes

Gauge: Available in any mil and microns.

• Health & Welfare Canada.
• Complies with EU Directives.
• Health Departments in Switzerland and Austria.
• Australian and New Zealand Food Authority.

(*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.
