Definitions
- the present invention relates to an antistatic sheet for laminating beverages and food containers and a method of manufacturing the same. Specifically, contact between containers during packaging and transport of beverage and food containers, adhesion of foreign substances due to static electricity, contamination by fine dust and surface scratches
- the present invention relates to an antistatic sheet for laminating beverages and food containers, and to a method of manufacturing the same, which prevents the occurrence, minimizes the sliding phenomenon of the food container, and facilitates separation between the containers, and reduces the curvature of the sheets.
- an insulating paper is used to cut and cut the original plate into a certain required size as a lamination sheet for the purpose of supporting or protecting the container in the process of manufacturing, packaging and transporting beverages and food containers.
- a broken fracture may occur in the cut surface, and surface scratches may occur due to friction between the surface of the lamination sheet and the container.
- the laminated sheet formed of the insulating paper is not provided with an antistatic function, and has a property of accumulating static electricity generated by contact and friction with other materials for a long time.
