Fresh corrugated carton typesfonmoo
This way you can ensure that your fruit is safe 5 at the same time the top of the box plus a thicker cardboard.
The country’s annual decay of fruits and vegetables more than 8 million tonnes, according to statistics. Ranked first in the world, resulting in economic losses of 75 billion yuan, accounting for 30% of the output value of the entire industry Therefore, fresh packaging as one of the important means of preserving fruits and vegetables, become an important link in the fruit and vegetable industry chain.
At the same time remove the ethylene gas that promotes the ripening and aging of fruits and vegetables. Therefore, the way to keep fruits and vegetables fresh is to reduce water loss, inhibit biological respiration and bacterial growth. A variety of fresh corrugated cardboard boxes came into being.
Its composite film or aluminium vapour coating on the inner surface of the traditional corrugated box, 1 with the function of heat insulation corrugated box for preservation of freshness. Or the use of foam resin instead of corrugated core paper, with excellent heat insulation, can prevent the circulation of fruits and vegetables in their own temperature rise.
Its inner surface of the corrugated carton is compounded with a layer of special-function freshness preservation film,2 freshness preservation corrugated carton with gas control function. Or mixed into the porous powder that can adsorb ethylene gas at the papermaking stage, it can effectively control the gas content inside the corrugated box, prevent water evaporation, and keep fruits and vegetables fresh.
This results in corrugated boxes with different preservation effects.3 By infiltrating liquid components with different preservation mechanisms into the corrugated board or by applying different coating treatments to the inner surface of the corrugated box.
The corrugated base paper is coated with a layer of special ceramic powder that emits infrared light at a wavelength of 614 μm, for example. This powder can emit infrared rays at room temperature, which not only activates the relevant molecules in fruits and vegetables and improves the ability of fruits and vegetables to resist microbial erosion, but also activates enzymes and improves the sweetness of fruits, which is widely used in the preservation and packaging of fruits such as peaches, grapes and prunes.
Combined with the production of corrugated boxes,4 nanotechnology is a popular technology at present. It can give corrugated boxes many new functions.
A Japanese paper company has produced a fruit and vegetable preservation corrugated box, for example. The inner surface of the corrugated box is laminated with a layer of polyethylene film, and then coated with a layer of waterproof wax coating containing trace amounts of nanoscale fruit and vegetable disinfectants, which prevents evaporation of water from fruits and vegetables and inhibits their respiration to achieve the purpose of preservation of freshness This type of preservation of corrugated cardboard boxes can keep fruits and vegetables fresh for one month.
The development of fruit and vegetable preservation technology can largely reduce the loss of agricultural products, no doubt. Ensure that farmers’ vital interests. Fruit and vegetable preservation corrugated box has a broad development potential.
Fruit packaging notes
For example, apples, 1 fruit packaging time to choose some very suitable for this kind of fruit a package of half materials. Sydney and other large fruits.
Not very soft, 2 at the same time the skin of these fruits is not very tender. Just make sure that these fruits are not pressed by something, so there is no fear of being crushed.
This way can be, 3 these generally use some sponge grid paper to set up. This is absolutely can, at the same time I pack the fruit.
At the same time to the whole box to be filled, 4 is best to put these fruits in a thicker box. This way you don’t have to worry about the collision between the fruits. This will prevent the fruit from getting hurt.
