Abstract

The utility model discloses a fresh-keeping packaging bag for nursery stock, which is used for forestry and gardening. The utility model is composed of a light reflecting outer layer 1 and a fresh-keeping inner layer 2. The light reflecting outer layer 1 is added with plastic films with high light reflecting rate, and the fresh-keeping inner layer 2 is added with the plastic films with volatile plant preservative. The utility model can prevent heat, keep wet, prevent mould and keep the biotic energy of the nursery stock, and the utility model is suitable for the storage and transportation of the nursery stock for a long time and using under natural condition in fields. The nursery stock keeping procedure and the management procedure are simplified, the production cost is reduced, and the utility model has the advantage of convenient operation.

Description

The nursery stock fresh-keeping packaging bag

The utility model relates to the packaging bag of the fresh-keeping usefulness of using on forestry, the gardening of nursery stock.

The packing of China sapling, fruit seedling still adopts ancient traditional materials such as straw bag, rush bag at present, these materials are preserved moisture, fresh keeping property is poor, easy air-dry dehydration and heating are gone mouldy, in nursery stock long-term storage and transportation, manage very complicated loaded down with trivial details, careless slightly, nursery stock survivability promptly descends rapidly even is dead, the therefore annual heavy losses that often take place.

The purpose of this utility model reaches the deficiencies in the prior art on being to overcome, and a kind of plastic film nursery stock fresh-keeping packaging bag is provided, have to nursery stock preserve moisture, fresh-keeping performance, can prolong the time that keeps nursery stock survivability effectively, and easy to use, be easy to management.

Nursery stock fresh-keeping packaging bag described in the utility model is made up of the two layers of plastic film, and skin is a reflector layer, adds high reflective material in plastic film, and the reflection of light rate is reached more than 50%; Internal layer is fresh-keeping layer, adds volatilizable plant antiseptic agent in plastic film.

Another technical solution of the present utility model is between the reflector layer and fresh-keeping layer of above-mentioned nursery stock fresh-keeping packaging bag, also has one deck light-absorption layer, and light-absorption layer is to add the high material of absorbance in plastic film, and the absorptivity of light is reached more than 90%.

The utility model is owing to adopt plastic film, and the nursery stock percentage of water loss is extremely low under air-proof condition, the room temperature storage through 30 days, and the nursery stock percentage of water loss is lower than 2.5%, has fundamentally solved the problem of nursery stock dehydration loss of life power in nursery stock Long-term Storage and the transportation; The outer reflector layer that adopts, can reflect the illumination more than 50%, especially after adopting light-absorption layer, can reflect and absorb the illumination more than 98%, effective thermal resistance, the interior warming effect of bag is obviously weakened, under the weather condition of phase of planting seedlings in early spring, two seasons of late fall, heat in the bag that solar radiation causes can not surpass and store the seedling safety temperature; Internal layer adopts fresh-keeping layer, by the gas that plant antiseptic agent evaporates, can suppress the germ growth and spread, and makes nursery stock be difficult for catching an illness and goes mouldy, and prolongs the safe storage phase; Therefore under general condition, the utility model can transport under field conditions (factors), deposit, and anti-the doing of needn't spraying water after the nursery stock pack needn't or be taken out to heel in with planting seedlings and keep a full stand of seedings on ground, garden, simplifies existing complexity loaded down with trivial details keep a full stand of seedings operation and management operation greatly; And the utility model physicochemical property is stable, and avirulence can be used under-50 ℃～30 ℃ temperature conditions, do not change the bag physicochemical property, and stronger mechanics of machinery intensity is arranged, the bag of filling nursery stock by predetermined quantity can deformation fracture, but repeated multiple times is used, and is with low cost.

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the side-looking cross-sectional view of first embodiment of the utility model

Fig. 2 is the side-looking portion face structural representation of second embodiment of the utility model

In first embodiment shown in Figure 1, reflective outer 1 is the plastic film that adds the strong material of luninous reflectancies such as Chinese white or flake aluminum, its luninous reflectance that adds flake aluminum can reach more than 60%, fresh-keeping internal layer 2 is the plastic films that add volatile plant antiseptic agent such as vanillic aldehyde masterbatch or copperas and citrate compound masterbatch, and the gas that volatilizes can make nursery stock be difficult for catching an illness to go mouldy.

In second embodiment shown in Figure 2, reflective outer 1 and the structure of fresh-keeping internal layer 2 and effect with described in first embodiment, and reflective outer 1 and the centre of fresh-keeping internal layer 2 also have one deck light-absorption layer 3, the absorptance of light-absorption layer 3 reaches more than 90%, be to add the high material of absorbance such as the plastic film of channel black masterbatch, process reflective outer 1 and light-absorption layer 3 can reflect and absorb the illumination more than 98% like this.

Claims

1. a nursery stock fresh-keeping packaging bag is characterized in that bag is to be composited by inside and outside two layers of plastic film, and outer (1) for being added with the reflector layer (1) of high reflective material, internal layer (2) is the fresh-keeping layer (2) that is added with the volatile plant anti fouling composition.

2. nursery stock fresh-keeping packaging bag according to claim 1 is characterized in that also being compounded with the light-absorption layer (3) that one deck is added with the high material of absorbance between reflective skin (1) and fresh-keeping internal layer (2).
