high hopes for beer bottles enliven packaging conferences.
So it\'s not surprising that on the latest Nova 13 out of 24 newspapers focused on beer packaging

The highlight is the first published comparison of multi-layer and barrier manufacturing costs

More new developments in beer bottles will be in Nova-atSchotland-
S. 2000 conference in Orlando, Florida.
At the end of this month.
The meeting will hear about two new plastic processing techniques for PET bottles and the overforming process of premade rods.
New barrier and coated beer manufacturers often say they need a bottle that can provide a shelf life of more than 120 days and lose less than 15% [CO. sub. 2]
Access to oxygen is no more than 1 ppm.
Internal or external coating, and three-or five-
To achieve this performance, the layer PET structure using barrier materials is being evaluated.

My office is in Schaumburg.
Bottles made with these two techniques are said to be completely recyclable, though completely recyclable
The scale test is still in progress.
The commercial release of technology will begin in the first quarter.
The first process is called Glaskin. the inner surface of the coat is very thin. the clear layer of silica uses avacuum-
It is reported that the \"glass\" coating can be applied at a speed of 6000 to 18,000 bottles/hour.
Designed for juices and carbonated soft drinks.
The coating is said to extend the shelf life of PET bottles from 4 months to 12 months.
It is reported that the silicon carrier can also maintain a good flavor.

Nano-composite material news-
The size of clay platelets scattered in the resin matrix is a new barrier concept for PET bottles.
In addition to the gas barrier, Nano clay is reported to give higher strength, stiffness, dimensional stability and heat resistance to the single layer PET structure, Chris Matayabas, project manager, Eastman Chemical
The aspect ratio of thick plates is more than 200: 1, layered in the polymer matrix, they create a \"tortuous path\" for gas molecules, reducing oxygen permeability to about 2. 66 cc-mil/100-sq-in-day-

The new MonoTherm process, he says, has raised pet appeal to 39-
42%, thus increasing the heat resistance to nearly 248 Fwhile while reducing the residual stress.
Produced bottles can withstand super
Hot filling of juice, tea and coffee.

The blowing process usually increases the crystalline degree of PET to 20%, and the heat resistance to about 185 F.
This is enough for pasteurization, except for beer, which has panels and ribs in the bottle due to its carbonated pressure.
MonoTherm controls the temperature of the bottle bottom, bottle body and neck by using three fluid loops in the mold, thus further improving the crystal degree of the bottle, about 176, 284-
320 and 68 F, respectively.
High blowing pressure forces the bottle to the hot mold.
Other process improvements are in the case of air cooling inside the bottle, a lower blow, a lower stretch ratio and a longer mold stay.
