Description

The flour packaging paper bag

The utility model relates to a kind of coated paper envelope, particularly a kind of flour packaging paper bag of packing powdered foods such as flour.

Because the flour powder is tiny, active area is big, and hole is little, very easily the moisture absorption caking, heating is gone mouldy, even the change of becoming sour is bitter, so should be noted that protection against the tide especially in storing, the anti-caking that goes mouldy, anti-high temperature and insect-pest, and transportation and the process of putting will prevent breakage, so the selection of packing, and be very big to influences such as the storage of flour and transportations.

The packaging bag of existing flour is generally adopted plastic film bag for small package bag, though plastic wrapping has the advantage of moistureproof and good waterproof performance, plastic wrapping exists: (1) plastic bag permeability to air is poor, the easy oxidation of flour in the bag, rotten; (2) film is thinner, and is damaged easily, subjects to insect pest, the plague of rats, produces loss; (3) unholiness, unhygienic, plastic wrapping must be used the food proprietary material, and is right owing to some producers and not according to this regulation, for cost-cutting uses some industrial plastics materials, can cause customer's physical impairment, because this possibility is arranged, the customer always has a lingering fear to plastic wrapping; (4) environment protecting is poor, can not reclaim after plastic sheeting is finished using, and can not decompose, and environment is polluted, and does not meet current international community packaging for foodstuff environmental demands; (5) can not prevent high temperature.

Cotton bag or victoria blended spinning cloth bag are generally adopted in the existing big packaging bag of flour, the cloth bag packing has sack to seal easily, and good permeability, packing can not produce the advantage of pollution to flour, but there is following shortcoming in the cloth bag packing: (1) cost is higher, and packing cost improves; (2) hygroscopic property is strong, and the easy moisture absorption of cotton is very easily made moist in wet weather, makes flour moisture absorption caking in the bag, moldy metamorphism, and in the particularly southern wet weather, this situation shows more obviously; (3) water-proofness is poor, and the cotton water-proofness is poor, if be caught in the rain or round water logging, cross cloth bag and infilter flour in the bag, and flour is become damp and rotten by the moisture very permeable in carrying, loading and unloading, storage for flour bag; (4) easily contaminated, cloth bag very easily is infected with filths such as dust, pollutes flour in the bag, clean inadequately health; (5) contaminated environment, the cloth bag material void is bigger, and often flour oozes out in the bag because of collision causes in handling process, forms dust, and contaminated environment produces loss; (6) damaged easily, cloth bag has only one deck packing, and is damaged easily; (7) insect-pest is poor, and the individual layer cloth bag is thinner, and very easily killed insect bite is broken, makes flour insect infestation in the bag; (8) anti-high temperature difference: the cotton high temperature resistance is poor, and the flour of newborn output can not pack at once, needs could pack after cooling a period of time, has increased unnecessary production time.

In view of this, how can among the deficiency of plastics and cloth bag, select a kind of reasonable price, ventilative, moistureproof, damp proof and and flour packaging bag that can compliance with environmental protection requirements, the utility model grinds wound motivation place just.

The purpose of this utility model can realize that the utility model overlaps a bag wall by laminated paper by following mode, and each ply of paper is by a plurality of abutting edges combination that is distributed in therebetween, and is at the bottom of bag that bag wall laminated paper is inwardly superimposed and bonding and seal; Sack of the present utility model is an open state; Described laminated paper is four layers of paper, and described laminated paper outermost layer is a stretchable paper, and internal layer adopts the flexible paper of person's character.

After having adopted technique scheme, the beneficial effects of the utility model are very tangible:

1, water-proofness, moisture resistance are good: owing to adopt laminated paper to make packaging bag, moisture content is difficult for infiltrating in the bag, and water proof, moisture resistance are good, under the rainy weather of humidity, can play waterproof, damp proof insulation effect effectively, prevent that flour from becoming damp and rotten.

2, clean health: the laminated paper sealed package, be hedged off from the outer world, the foreign minister pollutes in can preventing.

3, good permeability: the paper bag pore is fine and closely woven, and permeability is good, can prevent effectively that flour plays preservation because of airtight oxidation deterioration in the bag.

4, meet the environmental protection demand: paper bag is disposable use, can avoid cross pollution, after the use, also recyclablely utilizes as other purposes, does not pollute the environment, and meets current international community environmental protection trend and packaging for foodstuff environmental demands.

5, long shelf-life: characteristics such as because multilayer papery packing, permeability is good, waterproof, protection against the tide, anti-high warm nature are strong can make flour obtain the preservation of long period.

6, insect-pest is effective: paper bag seals easily, adds it is to be laminated paper, can prevent effectively that insect from entering, and flour is not corroded by insect pest in the protective bag.

7, anti-high temperature: the reason laminated paper is made bag, and heat-proof quality is good, a little less than the heat absorptivity, except that can playing the high temperature resistance effect effectively, preventing that the flour heating is gone bad in the bag; And the flour of just having produced can pack at once, has saved production time.

8, cracky not: adopt laminated paper and the compactedness of bag is strengthened, cracky does not effectively reduce the loss of flour in carrying, loading and unloading, in storing.
