This document discusses coating and laminating processes for paper and films. It describes several methods including extrusion coating, thermal laminating, wet bond laminating, dry bonding, solventless laminating, and extrusion laminating. Extrusion coating is commonly used to apply polyethylene to paperboard with benefits over wax coating like greater strength and moisture resistance. Laminating combines webs using thermal or chemical bonding with adhesives. Thermal laminating uses heat to bond adhesives while wet bond laminating relies on water or solvent. Dry bonding and solventless laminating avoid volatile organic compounds. The document also discusses factors in dry surface treatment coating like particle size and heat treatment to achieve an adequate coating layer.

Packaging design & innovation in foods and beveragesinewtrition
Do you want to choose the right packaging for your new product?
Do you want to strengthen your existing product as part of your marketing strategy and consider the alternatives to your current packaging?
Creating or selecting a food package is partly art and partly science. Both are significant and go hand in hand. Besides, designers must evaluate the technology push, market pull and socioeconomics carefully for successful packaging design.
To average consumers, food packaging is simply the enclosure of a food product in a plastic pouch, a metal can, or a glass bottle. To scientists or engineers, food packaging is a rather technical subject – it is a coordinated system designed for the efficient delivery of high quality, safe food products throughout the supply chain and the shelf-life. However, for food entrepreneurs, food packaging is all the above and more. The packaging gives you innovative ways to reach your customers. It enables you to communicate with your consumers as a marketing tool. For more information, please contact Raphaelle at info@inewtrition.com

This document discusses correlation and regression analysis. It defines scatter plots as graphs of independent (X) and dependent (Y) variable pairs that can show positive, negative, or no relationships between variables. The correlation coefficient measures the strength and direction of relationships, ranging from -1 to 1. A value of 0 indicates no linear relationship. Formulas are provided to compute the sample correlation coefficient and conduct a t-test to determine if a correlation is statistically significant. Examples demonstrate these concepts using data on wheat hardness and damage starch.
This document provides an overview of chi-square procedures for testing goodness of fit and independence using categorical data. It defines chi-square tests and presents examples to test if frequency distributions fit specific patterns or if two variables are independent. The examples show calculating expected frequencies, test statistics, degrees of freedom, and making decisions to reject or fail to reject the null hypothesis based on comparing test statistics to critical values at a given significance level.
This document provides an overview of analysis of variance (ANOVA), including:
- ANOVA is used to compare means of three or more populations using an F-test. It assumes normal distributions, independence, and equal variances.
- Between-group and within-group variances are calculated to determine the F-value. If F exceeds the critical value, the null hypothesis of equal means is rejected.
- Two-way ANOVA extends the technique to analyze two independent variables and their interaction effects on a dependent variable. Graphs can show interactions like disordinal, ordinal, or no interaction.
Ch6 Testing the Difference between Means, VariancesFarhan Alfin
The document discusses various statistical tests for comparing means and variances between two populations or groups. It provides formulas and examples for:
1. Testing the difference between two means with large independent samples using the z-test. This assumes normal distributions and known or large sample sizes.
2. Testing differences between two means with small independent samples using a t-test. This allows for unknown and unequal variances between populations.
3. Testing differences between two variances using an F-test, which compares the ratio of the two sample variances to an F distribution.
4. Calculating confidence intervals for the difference between two means with large or small independent samples.
1) Hypothesis testing involves specifying a null hypothesis (H0) and an alternative hypothesis (H1). The null hypothesis states that there is no difference or relationship, while the alternative hypothesis specifies a difference or relationship.
2) A statistical test is used to determine whether to reject the null hypothesis based on sample data. There is a risk of making Type I or Type II errors.
3) The p-value represents the probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
This document discusses key concepts in statistics for engineers and scientists such as point estimates, properties of good estimators, confidence intervals, and the t-distribution. A point estimate is a single numerical value used to estimate a population parameter from a sample. A good estimator must be unbiased, consistent, and relatively efficient. A confidence interval provides a range of values that is likely to contain the true population parameter based on the sample data and confidence level. The t-distribution is similar to the normal distribution but has greater variance and depends on degrees of freedom. Examples are provided to demonstrate how to calculate confidence intervals for means using the normal and t-distributions.
Ch3 Probability and The Normal Distribution Farhan Alfin
This document provides an introduction to probability and the normal distribution. It defines probability as the chance of an event occurring, and discusses empirical probability determined by observation. It introduces the normal distribution and its key properties including that it is symmetric and bell-shaped. The document also discusses calculating probabilities and areas under the standard normal curve, including between and outside given z-values.
This document provides an overview of key concepts in statistics for engineers and scientists. It discusses parameters and statistics, which are characteristics of populations and samples respectively. It then covers various measures of central tendency (mean, median, mode) and how to calculate them. It also discusses measures of variability such as range, variance, standard deviation, and coefficient of variation. Various distribution shapes are presented. Examples are provided to demonstrate calculating statistics like the mean, median, variance and coefficient of variation. The document aims to describe fundamental statistical concepts and calculations.
This document provides an introduction to statistics. It defines key statistical concepts such as descriptive statistics, inferential statistics, populations, samples, variables, and different types of data. It also discusses methods for organizing and summarizing data, including frequency distributions, histograms, frequency polygons, ogives, time series graphs and pie charts. The goal of statistics is to collect, organize, analyze and draw conclusions from data.
