Abstract

The utility model relates to a paper and plastic composite seed packaging bag which belongs to storage containers for articles or materials and is used for packaging, storing and transporting superior crop seeds. The packaging bag is characterized in that the back and the middle part of the bag are respectively and orderly composed of a transparent plastic film, composite raw paper, aluminum foil or an aluminized plastic film and a seal plastic film from exterior to interior, wherein the layers are compounded into a whole by adhesive. The packaging bag has the advantages of simple structure, easy fabrication and convenient use; the rate of humidity and oxygen permeability is completely in accordance with the need of seed loading, the seeds in the packaging bag are prevented from germinating and mildewing and are prevented from being suffocated, the rate of germination of the seeds stored for three years is above 80% after the seeds are sown.

Description

Paper-plastic composite seed packaging bag

The compound seed packaging bag of a kind of paper belongs to one of article or material storage vessel bag class technical field, is mainly used in good seed, the especially inner wrapping of package storage and crops such as various grains of transportation and vegetables.

It is a lot of to hold the container of storing seed in prior art, but in order to transport and especially inner wrapping easy to carry, nearly all is to use the plastic sheeting sack.Its thoroughly wet oxygen permeability of this single layer plastic sheeting sack is not too small, is exactly excessive, and causing seed of storing in it is not death by suffocation, is exactly to germinate in the high temperature and rainy sky to go rotten, and causes that after planting germination percentage is low, affects adversely and reduces harvest farming season.In order to improve the per unit area yield of crops, develop and promote good seed, the packing technique of seed is more and more paid attention to by people, and the packing of for this reason reforming good seed has become seed expert and vast farmers exigence.

It is a kind of simple in structure that the purpose of this utility model is to provide, make easily, easy to use, saturating wet oxygen permeability meets the needs of storing seed fully, guarantee that seed does not germinate, do not go rotten, after planting the germination percentage height is handsome in appearance, deflection is good, the seed compound seed packaging bag of light paper that rubs mutually within it.

Store and the special requirement of transportation and the characteristic of paper aluminum foil composite according to seed, at the subject matter that exists in the prior art, basic design of the present utility model is: adopt to be printed on pattern or/and the seed packaging bag of making different size is cut and sealed to the transparent plastic film of literal, composite base paper, aluminium foil or aluminized plastic film and involution with the composite material process that plastic sheeting is combined into one layer by layer, thereby realize design goal.

Of the present utility modelly be characterised in that the compound seed packaging bag of described paper is made of sack, bag abdomen, edge sealing and the bag back of the body, its prominent feature is that above-mentioned bag abdomen and bag back structure are identical, all serves as reasons to go up various pattern with different color by printing successively inward or/and the transparent plastic film of literal, composite base paper, aluminium foil or aluminized plastic film, involution constitute with plastic sheeting outward; Between the above-mentioned transparent plastic film and composite base paper, between composite base paper and aluminium foil or the aluminized plastic film and aluminium foil or aluminized plastic film and involution with all getting involved adhesives between the plastic sheeting, and above-mentioned four layers are combined into one through heating and pressurizing with dry compound machine by this adhesives; Cut then, doubling, three limits of heat-sealing promptly become bag.The inside and outside arrangement position that above-mentioned composite base paper and aluminium foil or aluminized plastic film are two layers can put upside down mutually or cancel wherein one deck, makes complex become three layers.

The utility model has the advantages that simple in structure, at most only needing four layers is combined into one, processing technology is also uncomplicated, can make the sack of different regulations according to the needs of different seeds, the relevant already professional detection of this sack department is detected, its thoroughly wet oxygen permeability meets the needs of the various crops seeds of splendid attire fully, guarantee that packaged seed does not germinate, do not go rotten, death by suffocation not, deposit in 3 years after planting germination percentage more than 80%, thereby guaranteed full stand and healthy seedling, for agricultural foison is created good condition, because this sack tow sides all can stamp various different colours at outermost layer in advance as required, the color graphics of different pattern or literal, so profile is very attractive in appearance, having improved the class of external packing, is by plastic sheeting because of it again, paper, aluminium foils etc. are composited by bonding, so deflection is good, the seed phase mutual friction of adorning in it is very light, and seed is without any damage; Pack seed transportation, store, use all very convenient with this bag, especially seal tightly, can avoid the lawless person toward the interior adulteration of good seed.

Accompanying drawing 1 is for one of the utility model most preferred embodiment integral structure and bag is carried on the back each layer raise and turn up one jiao front elevational schematic, and Fig. 2 be that bag is carried on the back a cross-sectional schematic top plan view.1 sack among the figure, 2 are positioned at the bag abdomen of the sack outside of belly, 3 are positioned at the involution plastic sheeting of sack innermost layer, 4 are positioned at sack outside in several the 3rd layer aluminium foil or aluminized plastic film, 5 be positioned at sack from outside toward the composite base paper of the mileage second layer, 6 are positioned at various pattern with different color in the printing of sack outermost layer or/and the transparent plastic film of literal, 7 edge sealing that the bag abdomen bag back of the body is connected as a single entity, and 8 are positioned at the bag back of the body at the sack back side.

It is the BOPP of 20 μ that outermost in this embodiment transparent plastic film 6 adopts thickness, its back of the body (just) face is printed on pattern and the seed corporate name of ten kinds of vegetables, abdomen (instead) face is printed on literal such as notice, by outward inward second layer composite base paper 5 adopt 70g/m ²Composite base paper, it is the aluminium foil of 9 μ that the 3rd layer of aluminium foil or aluminized plastic film 4 are selected thickness for use, it is the PE film of 50 μ that the innermost layer involution is selected thickness for use with plastic sheeting 3, layer with layer between get involved all that adhesives is successively compound to become one, cut then, doubling, left and right following three of heat-sealing all extrude the wide edge sealing of 8mm 7, bulk shape size length * wide=160 * 105(mm).

Change as present embodiment:

1, the bulk shape size can change according to different needs;

2, outermost BOPP can replace with 12～25 μ thick mylar or the thick nylon of 15～25 μ;

3, the 3rd layer aluminium foil can replace with the thick aluminized polyester film of 12～25 μ;

4, the aluminium foil 5 inside and outside arrangement positions of the composite base paper 4 of the second layer and the 3rd layer can be put upside down mutually, also can cancel wherein one deck, become three layers of compound sack.
