Abstract
The invention belongs to thermoplastic material and paper, aluminium composite molding technique method.In order to satisfy pressing for of agricultural, a kind of packing sack that meets the specific (special) requirements of splendid attire seed of development and production is main contents of the present invention.The Keeping life of crops such as grain, vegetables seed generally is 1～3 year.Comprise that material is wet thoroughly, oxygen permeability is too high or too low, directly influence the germination survivor's rate of seed.The present invention is through grinding examination repeatedly, finally made successfully a kind of by BOPP/ paper/aluminium/PE four layer materials through getting involved adhesives respectively, seed-packing bag of paper-plastic composite material by dry compound machine is made through heating and pressurizing through detecting index of quality, can satisfy the requirement of splendid attire seed fully.It is predicted that this product future market has a extensive future.
Description
The invention belongs to thermoplastic material and paper, aluminium composite molding technique method.
In China, because the minimizing gradually of ploughing, the good seed as crops grain, vegetables has become one of essential condition of developing agricultural.The peasant relies on good seed, obtains the good harvest fruit.Thereby the good seed of various inner wrappings, welcome by the peasant, in very great demand.Because the Keeping life of seed generally is 1～3 year, so to links such as packing, storage, transportations.Require strict especially.Promptly the germination percentage of seed must reach more than 90% in 3 years, and for this reason, to the packing of splendid attire seed, requirement must possess certain saturating wet, oxygen permeability.Saturating wet, oxygen permeability is excessive, seed germinates easily and goes rotten when the rainy weather of summer high temperature; If some oxygen does not see through yet, seed will death by suffocation.
Past splendid attire seed, easy to carry in order to transport except that generic container, mostly adopt the plastic sheeting sack.Facts have proved, most plastic sheeting sacks, saturating wet, all out of reach requirements of oxygen permeability cause the seed germination rate on the low side.Also find the unprincipled fellow who has simultaneously.Utilize plastic film packaging bag of low grade, the condition of easily manufacturing is printed the packing sack privately, sells false seed, entraps the peasant.For this reason, the seed packing are upgraded in agricultural experts and vast farmers an urgent demand, improve the quality of seed packaging bag, to satisfy the specific (special) requirements of agricultural to seed.
Purpose of the present invention is exactly: a kind of composite paper-plastic material that meets the special requirement of splendid attire seed of development and production, to make the seed packaging bag, satisfy the needs of agricultural.
The contriver finds in grinding examination, adopt density to be far longer than the aluminium foil A1 or the aluminizer of common plastics, can actv. play the effect of shading and oxygen flow, and after adding the paper composite bed, the deflection of composite material is strengthened, feel is fabulous, and then the seed packaging bag of making, its class, quality all are significantly improved, and have satisfied the specific (special) requirements of seed packing.
Technology contents of the present invention is: by skin is transparent plastic film, as Biaxially oriented polypropylene BOPP, [or polyester PET, or nylon NY] two layers be composite base paper, three layers are aluminium foil Al[or polyester aluminizer] nexine is the polythene PE film, [or haloflex CPE] is through getting involved adhesives respectively, pass through dry compound machine, or extrude compounding machine, and through heating and pressurizing, compound finishing.Made the composite material of forming by four layers, PE is as internal layer, according to the different needs of kind and quantity, through cutting, sealing during bag.Make the seed sack of different size.
Technological process of the present invention is:
One, will oneself printed pattern, the outermost layer BOPP of literal, its thickness is that 20～40 μ [or the thick PET of 12～25 μ, or the thick NY of 15～25 μ] on its seal face, get involved adhesives, with 60g/m
2～120g/m
2Quantitative composite base paper passes through dry compound machine, or extrudes compounding machine, through heating and pressurizing, is combined with each other, and makes BOPP/ paper composite bed; [or PET/ paper composite bed, or NY/ paper composite bed]
Two, aluminium foil Al[or the thick PET aluminizer of 12～25 μ that 9～12 μ are thick] the BOPP/ paper composite bed getting involved adhesives and be combined with each other, [or PET/ paper composite bed, or NY/ paper composite bed] pass through dry compound machine, or extrude compounding machine, through heating and pressurizing, be combined with each other, make BOPP/ paper/aluminium composite bed; [or PET/ paper/aluminium composite bed, or NY/ paper/aluminium composite bed];
Three, again that 30～50 μ are thick PE film, get involved adhesives and oneself compound good BOPP/ paper/aluminium composite bed [or PET/ paper/aluminium composite bed, or NY/ paper/aluminium composite bed, ] pass through dry compound machine, or extrude compounding machine, through heating and pressurizing, the compound BOPP/ paper/aluminium/PE composite bed [or PET/ paper/aluminium/PE, or NY/ paper/aluminium/PE composite bed] that is made for is promptly by four layers of composite material of forming; PE is as internal layer, according to the different needs of kind and quantity, through cutting, seal the seed sack of making different size during bag.
Four, the heating-up temperature of compound tense composite roll is 60 ℃～80 ℃, and pressure is 0.5～0.6MPa;
Five, selected adhesives is a polyurethane type, and concentration is 10～30%.
Enforcement of the present invention is: with its thickness of BOPP of pattern and character out of the press be 20 μ on its seal face, get involved adhesives and 70g/m
2Quantitative composite base paper is by dry compound machine, through heating and pressurizing, the compound BOPP/ paper composite bed of making; Again that 9 μ are thick aluminium foil Al gets involved adhesives and BOPP/ paper composite bed, by dry compound machine, and through heating and pressurizing, the compound BOPP/ paper/aluminium composite bed of making; At last that 50 μ are thick PE film is got involved adhesives and BOPP/ paper/aluminium composite bed; By dry compound machine, through heating and pressurizing, the compound BOPP/ paper/aluminium/four layers of composite material of PE of making;
PE according to the different needs of kind and quantity, cuts heat-sealing as internal layer during bag, makes the seed sack of different size.
The heating-up temperature of compound tense composite roll is 68 ℃ ± 3 ℃; Pressure is 0.6MPa; Selected adhesives is a polyurethane type, and concentration is 12%.
Characteristics of the present invention are: the seed packaging bag with this process is made, detect through specialty detection department, and wet oxygen transmission rate meets the needs of splendid attire seed fully thoroughly, and simple package bag on quality scale, all is significantly improved in the past; The sack deflection is good simultaneously, and the pattern and character of printing is clear, exquisite, so the future market has a extensive future.
