What sealed packaging technology

Sealed, also known as closed, sealing, after is refers to the packaging containers of products, in order to ensure that in shipment please packed commodities mediator in container, storage and sales process, and to avoid the pollution of all kinds of sealing process. Packing seal pile has a variety of methods and use of materials and components, such as adhesion, capping ( Plug, cap, etc. ) Nail, heat sealing and sealing, etc. Drill and two kinds of similar or different kinds of solid, the surface somewhere in between is another kind of material ( Adhesive) The role of and firmly combined phenomenon called glue. Say simply, diamond is the use of cat mixture on the method of sealing. This method has simple process, high productivity, combining strength, uniform stress distribution, good sealing, wide adaptation, and increase the advantages of thermal insulation, insulation performance, in the packaging industry are widely used in paper, cloth, wood, plastic, metal, and the combination of materials. In manufacturing, and sealing (sealing, composite material Box) , plastered and labeling process, play an important role. 1, cat theory between adhesive and be withered objects must have larger binding force to form a strong combination. The binding force can be: mechanical force glue seepage were dry content, forming 'glue nail forms of force; Van der Waals force of intermolecular force, directional gravity between polar molecules; Chemical force by the ionic bond and covalent bond, hydrogen bond and other chemical bonds to form force, etc.
