A paper mill in Montreal, Canada, has produced a self-adhesive sealing paper that can be used to wrap foods in order to avoid the trouble of binding or binding the wire ropes during packaging. The outer layer of the paper is kraft paper for writing and printing. The inner layer is a special polypropylene foam material. It has the properties of toughness, non-toxicity, moisturizing, heat preservation, etc. The juice and odor of the packaged food will not be leaked. In addition, this type of paper loses its adhesiveness once it is unsealed, and it has an anti-counterfeiting effect.
