A non-foil composite structure is provided having a substantial barrier to the loss of moisture, oxygen, and organic vapor and which is easily sealable with a shelf-life to at least one year for food and non-food products during dry shelf storage, and which is environmentally friendly. The laminate may have, from the outer atmosphere exposed surface to the inner surface contacting the contents of the container; a first exterior layer of a low density polyethylene polymer; a paperboard substrate; a first interior layer laminate coating of nylon with a tie layer; a second interior layer of low density polyethylene polymer; a third interior layer of high density polyethylene polymer; and an innermost and product contacting layer of low density polyethylene polymer.
