Description

TECHNICAL FIELD

[0001] The utility model relates to corrugated case technical field especially is related to a corrugated case of box sealing with corrugated board. BACKGROUND

[0002] Corrugated case is mainly composed of face paper, inner paper and corrugated core paper. Face paper and inner paper usually adopt box board paper with higher strength to provide the surface flatness and certain compression resistance and tear resistance of the carton. Corrugated core paper is processed into a wave shape through a special process, like a small spring closely arranged, which is the key to the good cushioning performance of corrugated case. Face paper, inner paper and corrugated core paper are bonded together by adhesive to form a whole paperboard structure, i.e. corrugated board, which is then made into corrugated case through die cutting, folding, binding or bonding process. Corrugated case has various structural forms, common ones are single corrugated case, double corrugated case and triple corrugated case, etc. Corrugated case is widely used in product packaging in various fields due to its good physical properties and economy. In the industrial field, it can be used for packaging electronic appliances, mechanical parts, automobile parts, etc. In the food industry, it can be used for packaging fruits, vegetables, beverages, cakes, etc. In the daily necessities, cosmetics and pharmaceutical industries, it is also a commonly used packaging container. In the process of logistics transportation, corrugated case can effectively protect the product from the impact of external forces such as extrusion, vibration, etc. to ensure the safety of the product during transportation, storage and handling. At the same time, it also has the advantages of easy printing, marking, recyclability, etc. Single facer is the key equipment for producing corrugated board, and its continuous improvement in technology has improved the production quality and efficiency of corrugated board. Modern single facer adopts advanced heating system, pressure control system and automatic paper receiving device, etc. to accurately control the temperature, pressure and speed of corrugated forming, ensuring the regular shape and uniform height of corrugation, and improving the flatness and strength of the paperboard. Die cutting process is used to cut corrugated board into various shapes and sizes to meet the packaging needs of different products. Traditional die cutting methods include flat-to-flat die cutting, round-to-round die cutting, etc. With the development of technology, new die cutting technologies such as laser die cutting and water jet die cutting have also been gradually applied to corrugated case manufacturing, which has the advantages of high cutting precision, fast speed and the ability to realize complex shape cutting. The existing corrugated case adopts adhesive tape for bonding during sealing, which wastes manpower and material resources, is complicated and time-consuming. At the same time, the corrugated case placed at the bottom is easily deformed under pressure during stacking, causing damage to the goods in the case. Moreover, the traditional corrugated case does not have waterproof and heat insulation functions. SUMMARY
