One-trip packaging

During the 1960s percipient environmentalists became aware that the increase in volume of synthetic pol3rmers, particularly in the form of one-trip packaging, presented a potential threat to the environment, what became evident in the appearance of plastics packaging litter in the streets, in the coimtryside and in the seas [8]. 

The general and product specification targets for ideal biodegradable plastics films, as recognized in laboratories concerned with the development of materials for one-trip packaging applications, can be listed as follows. They should ... 

We have to accept that the polyolefin group of plastics are remarkably successful as one-trip packaging materials in the form of films, blown bottles, and injection moulded containers. They are, however, astonishingly durable materials provided only that they are not exposed to... 

The fact that most packaging is one-trip is particularly true with pharmaceuticals, where the hazards of contamination and admixtures far outweigh other considerations. Hence the emphasis on recovery and recycling of the basic materials rather than reusing containers is to be welcomed. 

In analysing travel experience levels, 8 travel experience variables were used in this second study international trips level, domestic trips level, total international travel time, number of usual travel companion(s), proportion of international pleasure travel, proportion of domestic pleasure travel, level of organised/package travel experience, and self perceived level of travel experience. Before employing cluster analysis to identify different travel experience level groups, the variables were standardised variables subject to cluster analysis must be measured on equal scales as variables with large values contribute more to the calculations of distance measures than those with small values (SPSS Inc., 1999). One way to avoid... 

The in-vehicle navigation system, sometimes called a satnav, provides a compelling case in point. Today one can purchase and install for roughly 100 a unit that will successfully track the vehicle, match the track to a digital representation of a road network, identify an address or point of interest as the trip s destination, and provide detailed driving instructions. All of these services are provided by a package that is small enough to fit, unobtrusively, on the dashboard of a modern automobile.
