Description

Inner film-coated carton
Technical Field
The utility model belongs to the technical field of the packing carton technique and specifically relates to an interior tectorial membrane carton.
Background
The packaging carton is made of paper products, and is widely applied to occasions of packaging, article transportation, material arrangement and the like due to the advantages of low cost, easiness in packaging, suitability for adding fillers, cleanness and the like. The paperboard for producing the packing carton is generally formed by bonding surface paper, inner paper, core paper and corrugated paper which is processed into corrugated corrugations, and the paperboard is made into the packing carton with the side walls and the upper and lower turnover covers of the carton by die cutting, indentation, carton nailing or carton gluing.
Traditional packing carton can be at facial tissue surface tectorial membrane, and this kind of packing carton is not suitable for the packing transportation of cold chain product because in the transportation of cold chain product, can produce a large amount of steam, and steam is absorbed by the carton to destroy the carton structure from inside, cause the packing carton to collapse and become invalid. For example, during the transportation process of the fresh cut flowers, the fresh cut flowers need to be filled into plastic bags and then into cartons, ice cubes are placed in the cartons, and then the fresh cut flowers are transported to a destination through an airplane. The ice blocks melt to absorb heat, water molecules in the air form condensed water, the carton is affected with damp by the condensed water, and the carton is easy to collapse. Like many dairy products that need to be refrigerated for transportation, the inside moisture that produces of packing carton also can make the inside of carton damp collapse in the transportation. Based on such practical needs, technicians in the packaging industry have been dedicated to develop a packaging carton which has a simple structure and low cost and is suitable for the packaging and transportation of cold-storage and cold-chain products.
Chinese patent publication No. CN204641000U discloses a two-sided tectorial membrane corrugated container board, it includes facial tissue and base stock, the parallel is equipped with a plurality of flute layer between facial tissue and the base stock, the flute layer comprises one deck or two-layer corrugated paper, all be equipped with a rete on facial tissue and the base stock, the epimembranal printing has the pattern, the membrane is the OPP membrane. The corrugated layer is a layer; the corrugated layers are two or three layers, and a layer of sandwich paperboard is arranged between the corrugated layers; the corrugated layer and the sandwich paperboard are bonded and fixed by glue; the surface paper and the corrugated layer are fixed by adhesive, and the corrugated layer and the bottom paper are fixed by adhesive; the corrugated paper is of a wave-shaped structure. However, in practical production experiments, it is found that if hydrogel is used as an adhesive for adhering and fixing the paperboard, the existence of the double-sided film can make the water in the hydrogel very difficult to volatilize, the drying is difficult, bubbles can be formed on the surface of the paperboard even after the drying, the paperboard is unqualified, the production of the paperboard cannot be carried out in a normal production way, and the qualified packaging carton can not be produced naturally; if hot melt adhesives are used as the adhesive, the energy consumption is too high and the manufacturing cost is very high. In addition, the OPP film cannot be degraded and is not environment-friendly; and the material is not high-temperature resistant, and is easy to melt and adhere under the high-temperature condition.
Through a plurality of exploration tests, research personnel of our company develop a packaging carton which has simple structure and low cost and is suitable for packaging cold storage and cold chain products.

The inner protective film can completely cover the surface of the paper layer in the side wall of the carton.
The inner protective film can cover the surface of the paper layer in the lower turnover cover.
The inner protective film can cover the surface of the inner paper layer of the upper flip cover.
The inner protective film can be obtained by adopting the processes of film coating, film covering and the like.
The corrugated paper layer is a single layer, a double layer, a three-layer or a five-layer corrugated paper layer.
The inner protective film is a PET degradable plastic film.
The inner protective film is a waterproof coating.
Compared with the prior art, the beneficial effects of the utility model are that: when the technical scheme of the utility model is adopted to produce the paper box paperboard, local precise film covering is actually carried out on the surface of the inner paper layer of the paperboard, so that the moisture between the inner protective film and the outer protective film can move to the area which is not covered with the inner protective film by utilizing the siphon effect of the paper, thereby accelerating the drying of the paperboard and basically not forming bubbles; in addition, the local coating is adopted, so that the use of coating materials can be reduced, resources are saved, and the cost is reduced. Adopt the utility model discloses the packing carton of producing can prevent cold-stored, cold chain product package transportation in, inside produced steam, the infiltration carton such as comdenstion water of carton inside to destroy the carton structure, cause the carton to sink inefficacy, the carton lateral wall adopts the compressive strength that double-deck protection film also can strengthen the carton with flip down simultaneously. The utility model discloses simple structure, low in production cost is honest and clean, the packing transportation of cold-stored, cold chain product of specially adapted.
