Our paper tubes can be safe for dry goods that don't require shelf-life sustainability.
Food
grade paper is required for direct food contact. But we still recommend putting the
product
in a sealed bag and using the tubes as secondary outer packaging.
Aluminum foil and PE lining can be applied to create a food-safe, oil-resistant inner
barrier. Those tubes are generally sealed after filling to make them air-tight. Sealing
can
be done using metal discs, which requires specialized equipment, or shrink wrapping.
