14kl~24kl Food Grade Prd Flexitank

Multiple test qualification   PRD flexitank has passed the certification of food safety system FSSC22000, the ISO9001 international quality system certification, the state ministry of railways product quality inspection center, the qualification for railway transportation access CRCC, at the same time also acquired jewish kosher, FDA, Halal and EC food certification, by the American railway test AAR, at the same timeQingdao PRD Packing Material Co.,Ltd was the  member of COA.
High-strength nanometer polypropylene valve  Compared with ordinary or strengthened polypropylene, It has better properties of high/low temperature resistance and corrosion.  3' 'butterfly valve and  3' ball valve conform to the FDA, EC international food standards, such as valve with lock design is more secure.  Special anti-suction holes are added at bottom of valve , avoid inner PE film adsorbed onto the valve's bottom during unloading,reduce the residual amount of good greatly. Can withstand -20 ºC low temperature, the greater the intensity of special materials, with a strong collision is not crack. It has good sealing to guarantee the safe use of the valve, The PRD ball valves can bear the pressure of up to 8 KGS, no leakage, not burst; Butterfly valves can bear the brunt of the top 4 KGS.Valve screws with lock function, after lock will not open the screw, is to prevent to open the screw to steal goods.
Automatic exhaust setting   When the air pressure inside of flexitank is over 0.0065 Mpa ,the air vent will relief pressure automaticaly. Which always ensures the safety during the using process of flexitank all the time.
Liquid bag protective layer  The material of outside PP protective layer is used special PP with  polypropylene fiber ,which is not need to seam both sides and is more safer than PP flake and also improves the abration resisitance and permeability. It tensile load to 2056 N / 50 mm, percentage elongation after  fracture < 9%. This is different from common reworked material of PP on the market, our company use the PP all is pure new material.Inner PE completely conform to FDA, EC standards and has passed plasticizing  test, the maximum tensile load > 38N, percentage elongation after  fracture > 772% .
Unique sealing technology Unique 360 ° thermal bonding technology, It has  thechracter of  high heat sealing strength and good air-tightness . Each bag increased four protection strip and adoptes the automatic heat-seal machine , the time of heat-seal is accurate up to three-digit number after decimal point ,, which dramatically improves the endurance and shaking resistance
