The latest progress of bottle permeability technology

in terms of improving the oxygen and carbon dioxide permeability of T, PP and HDPE food bottles with the average value of PE as the hardness value of the test piece, Owens Illinois, m g polymers USA and PPG industries announced some progress of 7 inspection rules they have made

o-i`s Plastics Group (Toledo City, Ohio) has developed a new level of material surshot (an inert impermeable multilayer system) with anti delamination function, which is used to prepare pet and polyolefin bottles. Delamination is most likely to occur at the place where the container is embossed or inlaid. In view of this situation, O-I recombined its material, which can make the adhesion between layers stronger. In addition, O-I cooperated with husky injection moldingsystems (Bolton City, Ontario, Canada) to make the surge system suitable for Husky's new 144 cavity pre injection mold. The breakthrough of this technology is that the mechanical wear is large. In such a multi cavity mold, the thickness of the barrier layer is successfully controlled

M & G company in Houston has just launched actituf barrier resin in the United States. This is an active inert barrier system, which can 5. Hardness test: increase the storage period of food in PET bottles. In Europe, it has been used to make beer bottles. The preforming of bottles can be completed on ordinary instruments, and the production will not be reduced. Actituf costs a little more per pound than ordinary pet

PPG company (Milford City, Ohio) introduced a new material with higher permeability, which needs to be sprayed on pet, HDPE and PP bottles to form a barrier coating. This material is called bairocade HP. Compared with old materials, it can reduce the wall thickness of the bottle by 40%, and the oxygen and carbon dioxide permeability of the bottle is the same as that of the bottle made of old materials. Moreover, the new material coating can also be washed off when the bottle is recycled
