Abstract
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.
