| Name | Light weight PET collapsible barrel | Tranditional 3-5 gallon barrel |
| Material | PET(1st Food hygiene grade) | 7st Food hygiene grade PC; But
some small enterprise will use the
poor material which contains
hazardous substance which will
Dissolve in the water and contribute to the water pollution. |
| Permeability of the packing material | 02:ccmil/100inc2 per day 5 | 02:ccmil/100inc2 per day 250 |
| CO2:ccmil/100inc2 per day 19 | CO2:ccmil/100inc2 per day 1600 |
| Steam:g mil/100inc2 per day 0.4 | Steam:g mil/100inc2 per day 2.5 |
| Organics:cc ,il/100inc2 per day 4.3 | Organics:cc ,il/100inc2 per day 33 |
| Packing materials safty | PET cannot be involved in any other material. | PC barrels on the market have been
added no-foodgrade pigment. |
| Work flow | instant filling and capping after barrel blowing. | Purchasing the empty barrel or
recycle the old barrel in the
warehouse then filling after some
days later |
| Hygiene control | Single-use and without any chemical agent | Reproducible but not environmental |
| Materials separate out | PET can stand the high temperature and do
not separate out hazardous substance. | PC can not stand the high
temperature and UV, and will
separate out the BPA which can
result of the canceration and other
dysfunction. |
| Drinking health | All closed and no air contact during drinking time. | With air admission during drinking
time, 5 days later, drinking
hygiene drops sharply.
7 days later,the FPY drops to 20%.
10 days later, total number of bacterial colony all exceed standard. |
| Economy | Reduce 40% cost. | Material cost is higher than PET, it needs lots of money to purchase empty barrels and for drum broken. |
| Transportation | Single-use and without any fee | Transportation needed for recycle.
Not only iy cause the enviroment
pollution, but also needs higher
logistics cost. |
| Storage | No need and save the factory space | Big storage space and personnel
ganding needed , so add the labor
cost. |
| Packaging material properties | Without leakage for the injection-pulling-blowing technology.
Smooth outside, health, permeability, cleaness.
Hardly been broken for the injection tech.
Density:1.33-1.36g/cm3 | PC is without qualitative
organization and can be broken
easily for its extruding tech.
Density:1.20g/cm3. |
| Secondary poullution | The water dispenser adopts the principle of
atmospheric negative pressure, and causes
negative pressure inside the water when
the water is taken in, and the pressure container is
contracted according to the special design line, so as to achieve the purpose of water intake, so
no external
air is entered, and no pollution is achieved. | The air flows into the barrel to
depend on the number of water
quantity, they are equal.The pass of the external air is accompanied
by bacteria and impurities to enter,
even in a clean environment, per
cubic meter of air also has about
4000 bacteria, and the
external environment bacteria are
more active and stronger, high
survival rate, fast reproduction,
causing the water pollution in the
barrel. |
| Convinence | Can change barrels easily for women and elder.
Longer expiration date also save the water. | Bearers are necessary for barrels
change. With short expiration date,
it also causes much water waste. |
| Sale range | With cartoon box packing, they can be sold to farther district. It is convinent for high quality
mineral to be sold to intensive-consumption
market. | Be restcicted by the recycle, you cannot sell it to far destrict. |
| Consumption experience | Single-use, clean, sealed. | Reusing, air contactor, dirty. |
