摘要:

AbstractThe microbiological quality of aseptic packaging (the board for long‐life milk) was good and viable counts were under 50cfu per package. The percentage of defective samples that had viable microorganisms after 7–14 days of pre‐incubation was 54% (one pin‐hole) and 54% (ten pin‐holes) for coffee beverage packed in board B and 17% (one pin‐hole) and 17% (10 pin‐holes) for milk packed in board A. The differences in the percentage of defective samples between milk and coffee beverage and between board A and board B were significant, but no difference was observed between one and ten pin‐holes. An increase in fat content or a decrease in protein content increased the permeation of milk components through the pin‐holes. The microorganisms isolated from the products with artificial pin‐holes were f actobacillus sp. (52%), Streptococcus sp. (48 %) and Enter

摘要:

AbstractThe cost of producing folding boxboard cartons is dependent on a number of factors, among the most important of which are: machine costs, material costs and overheads.In estimating costs, decisions must be made that are often based on experience rather than on a precise knowledge of he facts. The use of an expert system can provide a more effective tool and procedure than that used currently.Part one of this report illustrates the effects of some of the variables, while part two describes the OPTICALC expert system devised by the authors.

摘要:

AbstractThe concept of using paper in medical packaging has been accepted widely. as it provides the essential permeability to allow ingress of the sterilising media whilst preventing the post‐penetration of bacteria. thereby maintaining sterility of the medical device itself.In Europe this widespread application of paper has demanded the introduction of proper standards for sterilization papers and converted items, such as bags and pouches. In this article these standards are discussed, i.e. British Standards, German DIN 58953, French Pharmacopoeia and Eucomed (European Confederation of Medical Suppliers Association).Comparisons of these standards, including results of our testing, also are presented t o underline the essential differences between specifications for the same grade of paper. In particular, special note is made in the case of air permeability of papers used for gas sterilization. The most reasonable solution is put forward by Eucomed, in which permeability performance is more fully addressed. The principles of various methods for the determination of microbial barrier performances of sterilization papers also are described and some comments in this respect are give
