Store up to 20kg of bulk provisions, rice, grains, flour, sugar, and pulses with Fresherpack Premium 50cm x 75cm (20" x 30") Mylar Foil Bags. Designed to line 20-litre to 25-litre (5-gallon) buckets or serve as standalone sacks, these heavy-duty bulk pouches feature a real pure aluminium core sandwiched between high-barrier polymers to deliver total light, oxygen, moisture, and odour protection for up to 20 years.

Why Choose Fresherpack Premium Mylar Foil Bags?

  • Thicker Than Standard Alternatives

    Featuring an impressive 5.1 Mil (131µm) single-wall thickness (10.2 Mil total when sealed), providing vastly superior physical strength and puncture resistance compared to thin 3.5 Mil market alternatives.

  • Real Pure Aluminium Core Layer

    Contains a continuous layer of aluminium foil rather than cheap spray-on metallised coating, ensuring zero pinholes and complete barrier protection against light, UV, moisture, and oxygen.

  • 100% Smellproof & Moistureproof Barrier

    Once heat-sealed, internal aromas cannot escape and external ambient moisture cannot enter, keeping delicate contents fresh and dry for up to 20 years when combined with an oxygen absorber.

  • Boil-in-Bag & Extreme Temperature Rated

    Engineered with specialized heat-resistant adhesives—safe for deep freezing down to -60°C and boil-in-the-bag heating up to 100°C for up to 30 minutes.

  • Easy Heat Sealing & Opening

    Seals quickly using a household flat iron or hair straightener. Includes a pre-cut side tear notch above the opening for convenient hand-opening once sealed.
