Envelopes for holding one or more items include a first and a second flexible wall. The second wall overlies, and is affixed to the first flexible wall. The second flexible wall can include a plurality of overlying layers of paper affixed to each other so as to define an interlayer region within which at least two of the plurality of overlying layers of paper are not adhered to each other.

The paper recyclable heat sealable bag includes a heat sealable water soluble inner layer coating and an article of paper. The heat sealable coating is applied to the article of paper by a printing press. As the printing press applies the heat sealable coating to the article of paper, the paper recyclable heat sealable bag may be wound into a master roll with a plurality of paper recyclable heat sealable bags. The master roll is fed into an automatic packaging system which fills the bags with a product from at least one of a top edge and a side edge of the paper recyclable heat sealable bags. The paper recyclable heat sealable bag has certain perforations to remove the paper recyclable heat sealable bag more easily from the master roll and sealed with a heat sealer.

Envelopes include a closure seal formed from a hot-melt adhesive. The hot-melt adhesive is reactivated after an item to be packaged is inserted into a pocket of the envelope by way of an opening defined by walls of the envelope. The reactivation of the hot-melt adhesive results in the formation of the closure seal, which affixes portions of the walls to each other so as to close the opening, causing the item to be retained within the envelope.
