Coated Packaging Products, Systems And Methods
In a method of forming a coated bag for pre-treating an item stored in the bag, a bag is provided, having a sidewall extending from a closed bottom end to an open top end and defining an interior surface of a cavity. The bag is expanded from a flattened condition to an expanded condition. At least one adhesive dispenser is inserted through the open top end of the bag into the cavity. An adhesive is applied from the at least one inserted adhesive dispenser to form an adhesive coating on the interior surface of the cavity. A particulate dispenser is inserted through the open top end of the bag into the cavity. A particulate is discharged from the inserted particulate dispenser to embed the particulate in the adhesive coating. The adhesive coating is dried to retain the embedded particulate on the interior surface of the sidewall.
