Shown above is a BOPP to BOPP two ply label.
Two ply labels consist of two plies of paper or film glued to each other with a combination of permanent, deadened and releasable adhesives. There are two common materials that we use: film to film and paper to paper.
The film to film is often produced on BOPP to BOPP materials which stands for Biaxially Oriented Polypropylene. The film to film is the most durable, functional and arguably most attractive. Paper to paper is used when a customer doesn't want the "film" look. It's more difficult to make paper to paper because the glues sometimes "soak" into the paper causing an uneven coating which results in the paper fusing. Paper to paper, however, is often the choice when a customer wants to maintain a paper look for products like food, beauty and green products. Don't misunderstand. We can make a very good paper to paper two ply. It just doesn't function as flawlessly, in our opinion, as a BOPP to BOPP.
We use two types of glue patterns to make our two ply labels. The first is a perimeter glue pattern where the glue is deadened all around the label with the exception of the edge and the hinge area. The second pattern is a flood coat of adhesive deadening and release coatings. Both patterns allow for the customer to open and reseal. It's a matter of preference and application.
