In the food industry, plastic or paper bags are used to commercialize bulk products like flour, salt and sugar. Normally, these types of bags are sealed with cold glue applications, due to the lower cost of the adhesive and the stronger bond in the long term. Optionally, plastic and paper bags can also be sealed by applying hot melt adhesive. This creates a faster bond and is recommended for higher line speeds. If you do not see the specific application you need, let us know.
