Corrugated box technology new developments

Normal > Corrugated carton has been widely used in electronic products, foods, fruits, etc. because of its advantages of light weight, high strength, easy processing and forming, easy storage and handling, easy recycling and recycling, excellent printability, and low cost. Industrial devices, stationery and other sales packaging and transportation packaging. Of course, the market position of corrugated cartons has also been affected. For example, according to a survey conducted by the latest European corrugated board manufacturer association and French corrugated board packaging association, recyclable plastic boxes have been available since the market's recyclable plastic containers.

Normal > one. Various new features corrugated boxes

Normal > ( 1 ) Tamper-resistant carton packaging

Normal > In order to solve the problem of stolen goods by the distributor in the process of transportation, a new tamper-proof carton pack was introduced. Its structural features are: the box body and the two bottom plates form a three-piece corrugated cardboard box The lid of the carton is sealed by a hot melt glued seal system. In this way, the carton does not have a top flap. If you want to steal, you must tear or damage the entire carton. Currently, this packaging has been adopted by those businesses that have serious theft problems in the supply chain.

Normal > ( 2 ) Fresh-keeping corrugated carton

Normal > Corrugated cartons are currently used primarily as containers for the transport of goods between consumer and production, and have attracted great attention in particular for fresh packaging for fresh vegetables and fruits. The following mainly introduces three kinds of corrugated cartons with preservation function.

Normal > A type of corrugated carton with thermal insulation. This type of corrugated carton is provided with a composite resin and an aluminum vapor-deposited film in a conventional carton, an outer layer, or a foamed resin in a paper core. As a result, it has excellent thermal insulation and can prevent the temperature of fruits and vegetables from increasing in the middle of circulation. At low temperatures, not only the respiration of vegetables and fruits is weakened, but also the activity of bacteria is greatly reduced, so it has a good preservation function.

Normal > The other is a corrugated box with a controlled atmosphere function. This type of corrugated box sandwiches the cling film in the inner liner and the outer liner of the carton, or mixes porous powder capable of adsorbing ethylene gas at the papermaking stage. It is gas-barrier, prevents the evaporation of moisture from fruits and vegetables and achieves the effect of controlling the gas content, thereby maintaining the freshness of fruits and vegetables.

Normal > There is also a far-infrared corrugated cardboard fruit box. This new type of fruit packing box is made of far infrared corrugated cardboard. Far-infrared corrugated board is made of corrugated paperboard made of 100% natural pulp and coated with a layer of ceramic that can emit far-infrared rays. Then, a layer of polyethylene film is coated on the ceramic coating. Prevents ceramic shedding. After the natural corrugated paperboard is processed into such a fruit packing box, the loaded fruit can be stored in a normal corrugated cardboard fruit packing box by approximately twice the freshness under the influence of far infrared rays.
