Product Description:

Our paper bag production line consists of paper tube forming machine(Tuber) and bottom pasting machine(Bottomer). The products-Valve bags are used for a vast number of applications, primarily in the building materials and food industries, to filling goods such as:cement,chemical material, feeds, fertilizers,tea,rice etc.

Our Advantage:
1.Specialize in design and manufacture valve paper bag machine for 30 years;
2.CE Certified;
3.Our tuber machine and bottomer machine have gained over 50 utility model patents;
4.Longer service life with NSK bearings,SIEMENS control system and high quality gearings.
5.Cost effective compare to W&H,Germany and Newlong,Japan.
Valve paper Bags:
Different models can produce different kinds of bags,like standard cement bags,chemical/cement bags with bottom strengthen sheet,tea bag with PP Liner to enhanced moisture protection.

Bags can be made of 2~4 layers kraft paper or paper with one layer of PE/PP film.2~4 colors printing available in Tuber line.
The bags opening or valve in one corner through which the sack is filled. The valve is made with an inner flap which functions as a self-closing check valve after filling. It is available with a plain valve or with an extended inner sleeve of paper or film.

Q:PVC double wall corrugated tube forming machine computer screen shows down drive servo abnormal. What's the matter?
Production technology and equipment structure of PE double wall corrugated pipeFirst, the production process, mixing drying, extrusion molding, spray coolingDrycuttingPipe inspectionPackingStorage
Q:What are the factors affecting the packaging quality of bag molding, filling, sealing and packaging?
The heat sealing pressure is the external power of mutual penetration and diffusion of the molecules in the interface between the viscous plastic film; heat sealing time will make the interface molecular plastic film as soon as possible mutual penetration and diffusion, the interface disappears and as a whole, which has a good sealing performance.
Q:What are the features of carton packaging machines? Introduce concretely
According to the product line can be divided into: carton forming machine, carton forming machine, packing machine, box machine, paper carton machine, unloading machine, etc..According to the degree of automation of the machine can be divided into: automatic forming machine, automatic carton forming machine, etc..
Q:What are the forms of packaging and the forming process of textiles? The more detailed, the better
If you can be multiplied by the number of flowers, reed first calculate the entire width of a number of flowers, number of teeth and with the head part of the number of teeth and the selvage is equal to the total number of teeth. The root number is based on the pattern of selvage selvage can determine, plain do less, while 24 can be, if it is to do or twill jacquard 1.5 cm,
Q:Types of blow molded products
The scope of application is also increasingly widespread. At present, containers account for about 80% of the market share, increasing by about 4% annually, while industrial and structural products account for 20% of the total, and the annual growth rate is 12%
Q:Why should heat treatment be made after glass molding?
Glass itself is very fragile, forming after the general empty, cold for a period of time, so that it has a certain intensity
Q:Blow molding process conditions The purpose of the adjustment of technological conditions is that,
Use the established computer model to simulate the status of blow molding die, blanking billet and clamp plate;Enter the parameters affecting the wall thickness distribution of parison at each stage;The simulation results are analyzed, and computer simulation shows that the wall thickness is not enough, and which parts are super thick;
Q:How much is the gas consumption per EPS molding machine per hour?
Automatic vacuum packaging foam molding machine, ICF thermal module molding machine, hydraulic press automatic molding machine, and foam raw material manufacturer (dragon company) jointly developed the forming process, the process of forming speed, saving steam, products of good quality, shorten the drying time.
Q:What are the characteristics of plastic thermoforming?
Molding in plastic processingPlastic packaging, blister boxes, packaging boxes, plastic packaging, blister, PVC packaging, PET packaging, folding box packaging, plastic tray, blister lining,Plastic box packingAdaptability. It can be made of super big, small, super thick and thin parts by using thermoforming method. The thickness of the board used as raw material can be as thin as 1~2mmEven thinner; the surface area of the product is large to 10m2That belongs to the half shell structure, small to a few square millimeters; wall thickness can reach 20mm
Q:How does the pulp solidify? What additives do you need? Curing agents?
(1) urea formaldehyde moulding powder;The resin powder of urea formaldehyde resin, commonly known as electric jade powder, is produced by wet process, such as tree ester, curing agent, filler, colorant, lubricant, stabilizer, plasticizer and so on1 Components(1) resin used for urea formaldehyde resin molding powder by condensation reaction degree is relatively shallow, the resin with low viscosity, easy dipping filler, and can ensure the long production cycle and drying after proper fluidity, condensate in the industrial use of urea and formaldehyde at low temperature (a mixture of dimethylol urea, urea and formaldehyde) are usually used. The ratio of 1:1.5 (molar ratio), the PH=8 (and temperature) 30 - 35 of all dissolved, adding urea oxalate was 0.3% - 0.33% and 0.88% - 0.54% of the oxalic acid, then the occurrence of exothermic reaction, temperature rise, temperature in 55 - 60 degrees, and strictly control the PH=5.5 - 6.5, 60 - 75min by urea formaldehyde resin is required. Because the condensation degree is low, in fact just over addition reaction, condensation reaction is mainly in the curing process.(2) the curing agent used in curing agent and pressing powder requires latent, usually oxalic acid, phthalic acid, two formic acid, benzoic acid, chloroacetic acid, etc.(3) packing material is the most commonly used pulp, followed by wood powder or inorganic fillers (glass fiber, asbestos, mica etc.). The pulp is wood as raw material, with sodium bisulfite, non soluble cellulose impurities to the wood, and then byThat is the pure cellulose bleaching. The amount of filler material for the total amount of 25%-32%, the amount is too small, the pressure of plastic powder fluidity big, product strength is low; on the contrary, the amount of excessive pressure, plastic powder fluidity decreases, the product surface is not smooth, water
