Abstract
The utility model relates to composite paper for cement packing bags. The utility model at least comprises brown paper and a plastic film which are connected by adhesive, or one side of the plastic film is additional provided with a layer of brown paper or non-woven cloth or fabric cloth which are connected to the plastic film by adhesive. The cement bag made of composite paper has the advantages of low cost, good water and humidity resistance, and high intensity. The utility model can bear free-fall of five meters without being damaged in the process of transportation of cement.
Description
The utility model relates to package paper, more particularly, relates to the cement package bags extrusion coating paper.
The cement package bags majority of selling on the market all is to make without bonding craft paper by 5 layers at present, its intensity is lower, break easily after the pack, particularly in handling process when eminence falls, easier cracking or breakage when perhaps running into extruding or friction, cause cement to leak, therefore cause serious loss.In addition because craft paper can not waterproof so that in transporting procedures, run into rainy, haze or weather condition such as humidity and cause the cement damp failure, also can cause tremendous loss.According to incompletely statistics, China's economic loss damaged because of cement package bags and that the cement damp failure causes reaches several hundred million units.Various high strength cement packaging bags have appearred in recent years, these packaging bags or use the woven bag inner lining plastic bag, or with woven bag and kraft compounded and make.Although these products have been taked some up-to-date technologys, thereby overcome the problem of intensity difference, yet can not water repellant problem still exist, and cost and price are higher, embarrass producer and user to accept.
The purpose of this utility model is will provide a kind of to have simultaneously that cost is low, water resistance good and the cement package bags extrusion coating paper of multiple advantage such as intensity height.Said intensity height should be able to reach tensile strength 50Kg/cm
2More than, and the cement bag that can allow the packed 50Kg cement of standard falls and not damaged from 5 meters eminences, so just can remove and bring up to the worry that the bag of cement breakage takes place when moving down in handling process.
Scheme of the present utility model is to form a kind of extrusion coating paper that has 3 layer laminate structures at least with craft paper, adhesive agent and plastic sheeting, also available craft paper, adhesives, plastic sheeting, nonwoven fabrics or woven cloth are formed a kind of extrusion coating paper with 5 layer laminate structures, these extrusion coating papers promptly can be used as cement sack paper, also can do powder package paper or file pouch with paper, they have enough good waterproof and dampproof performance and sufficiently high intensity, and are and with low cost.
That is to say that the utility model provides a kind of high strength cement packaging bag extrusion coating paper, it is characterized in that it is a kind of extrusion coating paper that has 3 layer laminate structures at least that contains craft paper, adhesive agent and plastic sheeting.
In above-mentioned extrusion coating paper, said 3-tier architecture is meant a two-layer lining and a layer binder.The kind of said plastic sheeting does not have strict restriction, as long as it has enough toughness, but preferably polyethylene or polypropylene film, because these two kinds of plastic sheetings have higher intensity, and plasticizer-containing not, therefore can be owing to the release of plasticizer is worn out.In addition, its cost is also lower, easily accepts for producer.The thickness of said plastic sheeting does not have strict restriction yet, but general preferable thickness is 0.02-0.1mm, is preferably 0.04-0.08mm.Said adhesive agent does not have strict restriction yet, as long as it all has enough cohesive forces and still have certain toughness or elasticity after finishing the bonding process plastic sheeting and craft paper, but preferable adhesive agent is uncle's butylene class adhesive agent, wherein best example is the DN303 adhesive agent, when the plastic sheeting bonding of implementing with this class adhesive agent polyethylene kind, preferably follow and use 90-110 ℃ heated lamination technology, can further improve bond effect like this.
In addition, the utility model is on the basis of above-mentioned first kind of scheme, another kind of high strength cement packaging bag extrusion coating paper also is provided, has it is characterized in that, it is the extrusion coating paper that contains 5 layer laminate structures of craft paper, adhesive agent, plastic sheeting, adhesive agent and craft paper.
In this extrusion coating paper, said 5 layers of structure are meant 3 aspect material and two layer binders, and this two layer binder can be identical or different, and its selection principle is also as above-mentioned.
The utility model also provides another kind of high strength cement packaging bag extrusion coating paper on the basis of above-mentioned first kind of scheme, it is characterized in that, it is the extrusion coating paper that contains 5 layer laminate structures of craft paper, adhesive agent, plastic sheeting, adhesive agent and nonwoven fabrics.
The utility model also provides another kind of high strength cement packaging bag extrusion coating paper on the basis of above-mentioned first kind of scheme, it is characterized in that, it is the extrusion coating paper that contains 5 layer laminate structures of craft paper, adhesive agent, plastic sheeting, adhesive agent and woven cloth.
Compared with prior art, high strength cement packaging bag of the present utility model has the multiple advantage that cost is low, intensity is high, waterproof and dampproof performance is good with paper, thereby has substantive distinguishing features and progress.
Further explain the present invention below in conjunction with accompanying drawing, in each accompanying drawing, commaterial is with identical coded representation.Wherein:
Fig. 1 is the exemplary plot of first kind of scheme of the utility model, and it contains: layers of kraft paper 1, adhesive layer 2, plastic film layers 3.
Fig. 2 is the exemplary plot of second kind of scheme of the utility model, and it contains: layers of kraft paper 1, adhesive layer 2, plastic film layers 3, adhesive layer 2, layers of kraft paper 1.
Fig. 3 is the exemplary plot of the third scheme of the utility model, and it contains: layers of kraft paper 1, adhesive layer 2, plastic film layers 3, adhesive layer 2, nonwoven layer 4.
Fig. 4 is the exemplary plot of the 4th kind of scheme of the utility model, and it contains: layers of kraft paper 1, adhesive layer 2, plastic film layers 3, adhesive layer 2, base fabric 5.
Enumerate embodiment below and further explain the utility model, yet this embodiment can not be as to restriction of the present utility model.
According to structure shown in Figure 1, adopt common craft paper of one deck and the thick polyethylene foil of one deck 0.05mm, coated DN303 adhesive agent between the two uses thermal composite machine to carry out composition operation then, and combined temp is 100 ± 2 ℃.Promptly obtain a kind of extrusion coating paper of 3-tier architecture after compound, make a kind of craft paper standard cement bag outwardly, make 10 bags altogether, every packed sealing behind the 50Kg portland cement of going into this extrusion coating paper.Then these 10 bags of cement are removed to three floors, from the window (high about 6 meters) in the 3rd buildings these 10 bags of cement are down thrown, the neither one bag of cement takes place damaged as a result.
By above result as can be seen, the bag of cement with the 3-tier architecture (being two-layer lining) that comprises plastic sheeting can satisfy the requirement of intensity basically with paper.If but considered that the number of times that loads and unloads is more in transportation, preferably would be made into bag of cement extrusion coating paper with the 5 layers of structure (i.e. 3 aspect material, 2 layer binders) that comprise plastic sheeting.
