Q:Food, equipment, tools, containers, packaging materials, etc. shall comply with food safety standards or requirements

Hygienic standard for polyethylene terephthalate resin for GB 13114 food containers and packaging materialsGB, 13113-1991. Hygienic standard for polyethylene terephthalate molded articles for food containers and packaging materials

Q:How does the pulp solidify? What additives do you need? Curing agents? Or what do you need as binders?

(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

Q:Which friend is an expert in mechanical equipment or a better understanding of sealing machines? Tell me how to identify the equipment

There are PLC control ah, if it is fully automatic, then ask the quality of sealing ah, it is best to let manufacturers give you a live demonstration, the soft power depends on the size of the factory, ah, after-sales service ah!

Q:What are the packaging machines that use temperature control watches?

Direct heating sealing machine, blister packing machine, plastic sealing machine, heating pot, oven, toaster and so on

Q:What's the fastest packing machine?

Depending on the characteristics of your material, the speed is adjustable!

Q:What kind of reducer is commonly used in packaging machinery?

There are many kinds of reducers used. What kind of machines are they under?

Q:Whether you can press paper plastic molding after PET

Sure；Note cards must be coated with plastic oil;Can use blister sealing machine or high frequency plastic welding machine hot pressing;

Q:Color code positioning of packaging machinery

The use of the printed color packaging materials, photoelectric switch (available on the color electric eye tracking and positioning), through the control system to drive the stepper motor rotation and color according to the distance between the automatic stop, to complete and accurate packaging products logo.

Q:The role of food packaging machinery

3) to achieve manual packaging can not achieve the operation, some packaging operations, such as vacuum packaging, inflatable packaging, body packing, isobaric filling, etc., are manual packaging can not be achieved, can only be achieved by mechanical packaging.(4) can reduce labor intensity, improve the working conditions of the labor intensity of manual packaging, such as volume, weight heavy manual packaging products, both the consumption of physical strength, and safety; and for small and light products, due to high frequency, easy to make the action monotonous, worker occupation disease. Carton folding machine(5) in favor of labor protection for some serious impact on health products, such as serious dust, toxic products, irritating, radioactive products, manual packaging is a health hazard, and packaging machinery can be avoided, and can effectively protect the environment from being polluted.(6) it can reduce the cost of packing and save the storage and transportation expenses. It can reduce the volume and reduce the packing cost by compressing and packing the loose products, such as cotton, tobacco leaf, silk and hemp. At the same time, due to the reduction of large volume, in order to save storage capacity, reduce storage costs, is conducive to the transport.(7) ensure product health of certain products, such as food and drug packaging, according to the health law is not allowed to use manual packaging, because it will pollute the products and packaging machinery to avoid direct contact with the staff of food and medicine, to ensure the quality of health.

Q:What machine does the packing carton machine have?

Packaging equipment including: automatic strapping machine, automatic sealing machine, winding (wrapping) machine, sealing and cutting / shrink machine, vacuum packing machine, automatic strapping machine band and hand tools. Transport equipment mainly include: conveyor belt, roller conveyor, conveyor chain plate, plug-in production line, chain conveyor, conveyor belt etc..
