Product Display Versus Graphical Representation On Packaging, Joshua Galvarino Dec 2012

Product Display Versus Graphical Representation On Packaging, Joshua Galvarino

All Theses

ABSTRACT
Previous research conducted (Hurley, et al., 2012) concerning physical and graphical product visibility from the primary display panel (PDP) is limited to one product category. This research expands previous peer-reviewed research, which indicates that there is a significant difference between consumer preferences of graphical display vs. physical product display on packaging.
The shelf presence of packages showing actual product visibility versus packages showing only a graphical representation of the product was evaluated. Both shopping results and quantitative data using eye-tracking technology were collected and cross-referenced with a qualitative, post-experiment survey.
Specifically, variables of packaging within pasta, snacks, prepared frozen ...


Relating Burst Pressure To Seal Peel Strength In Pouches, William Bernal Aug 2012

Relating Burst Pressure To Seal Peel Strength In Pouches, William Bernal

All Theses

This work was aimed at studying the relationship between burst pressure and seal peel strength. Past researchers developed a force balance equation based on the analysis of a force diagram to relate burst pressure to seal strength. The theoretical formula S=P(D/2) (S=Seal Strength, P=Burst Pressure, D=Restraining Plate Gap) has been studied by past researchers with contrasting results.
The theoretical formula was tested by varying dwell time to produce seals of varying strength. Pouches were burst tested at each of these dwell times to obtain burst pressures, burst peeling times, and burst locations. Corresponding peel ...


The Effect Of Food Ingredients On The Oxygen Barrier Properties Of Retort Materials, Amanda Ward Aug 2012

The Effect Of Food Ingredients On The Oxygen Barrier Properties Of Retort Materials, Amanda Ward

All Theses

An unexplored area in research is addressing how retorted food ingredients interact with retort packaging's oxygen barrier. Ten common food ingredients (whey protein isolate, soy protein isolate, bovine gelatin, fish gelatin, high molecular weight fish gelatin, water, air, oil, potato starch, and hydroxypropyl methylcellulose) were assessed to find their effect on the barrier properties of CPP, PET, and high barrier commercial retort pouches. OxySense Gen III 300 and Mocon OxTran 2/21 were used to evaluate the samples. CPP pouches were first assessed with the OxTran 2/21 and indicated that treatments affected the OTR's of the film ...


Determining The Proper Point Size For Display Type On Packaging, Joanna Fischer Aug 2012

Determining The Proper Point Size For Display Type On Packaging, Joanna Fischer

All Theses

Through the use of a preference test, the proper point size of display text on a package was evaluated in relation to a package's proportions. The test involved the examination of packaging images displaying the product or brand name in various point sizes by 150 participants who were then asked to choose the option they most preferred. The participants were then provided with a post-survey intended to gather additional information regarding potential preference motives.
The primary purpose of this study was to determine the most preferred display type size of a package based on its relationship with the package ...


Development And Characterization Of Shellac-Hydroxypropyl Methyl Cellulose Composite Films With Acid Catalyst, Sana Asrar Aug 2012

Development And Characterization Of Shellac-Hydroxypropyl Methyl Cellulose Composite Films With Acid Catalyst, Sana Asrar

All Theses

The objective of this research was to develop a shellac-hydroproyl methyl cellulose (Sh-HPMC) composite film with enhanced water vapor barrier. Citric acid (CA) was used as an acid catalyst, to promote miscibility between HPMC and shellac. In a preliminary test, three different concentrations of CA (1000:1, 200:1, 100:1) were tested to identify the best Sh:CA ratio. Based on the Water vapor permeability properties and mechanical properties, Sh-CA (1000:1 ratio) had the most enhanced water vapor barrier and the lowest reduction in tensile strength compared to the pure HPMC film (control). In the later part of ...


The Effect Of Full Body Versus Partial Body Graphic Labeling On Beverage Packaging, Toni Gomes May 2012

The Effect Of Full Body Versus Partial Body Graphic Labeling On Beverage Packaging, Toni Gomes

All Theses

Through the collection of quantitative and qualitative data, the shelf presence of
full body graphic labels versus partial body graphic labels on plastic beverage bottles was
examined and evaluated. Eye tracking was used to collect phenomenological data atop
the stimuli, while a shopping checklist was used to collect purchase preference. A postexperiment
survey was also conducted in order to gather qualitative data regarding
possible purchase influences.
The experiment was a 2 (label size) x 6 (beverage flavor) x 2 (age group) study,
conducted with 28 participants in a consumer retail environment using mobile eye
tracking technology. The goal of this ...


Statistical Analysis Of The Stress-Energy Methodology Applied To Cushion Curve Determination, Kendalyn Paulin May 2012

Statistical Analysis Of The Stress-Energy Methodology Applied To Cushion Curve Determination, Kendalyn Paulin

All Theses

The stress-energy method is a proposed enhancement to ASTM D1596 that reduces all drop height, thickness and static load combinations into a single equation that can be used to generate any reasonable cushion curve for a particular material. There remains a question as to how accurate the stress-energy method can predict acceleration values and whether it is statistically comparable to ASTM D1596. There are three phases to this research that attempt to determine the accuracy of the stress-energy method: gathering data using the stress-energy method and analyzing the goodness of fit of the stress-energy equation, predicting a cushion curve and ...
