A Method for Estimating Short-term Profitability, Case Stora Enso Packaging Boards

Tutkimuksen tavoitteena oli rakentaa case yritykselle malli lyhyen aikavälin kannattavuuden estimointia varten. Tutkimusmetodi on konstruktiivinen, ja malli kehitettiin laskentaihmisten avustuksella. Teoriaosassa käytiin kirjallisuuskatsauksen avulla läpi kannattavuutta, budjetointia sekä itse ennustamista. Teoriaosassa pyrittiin löytämään sellaisia menetelmiä, joita voitaisiin käyttää lyhyen aikavälin kannattavuuden estimoinnissa. Rakennettavalle mallille asetettujen vaatimusten mukaan menetelmäksi valittiin harkintaan perustuva menetelmä (judgmental). Tutkimuksen mukaan kannattavuuteen vaikuttaa myyntihinta ja –määrä, tuotanto, raaka-aineiden hinnat ja varaston muutos. Rakennettu malli toimii kohdeyrityksessä kohtalaisen hyvin ja huomattavaa on se, että eri tehtaiden ja eri koneiden väliset erot saattavat olla kohtuullisen suuret. Nämä erot johtuvat pääasiassa tehtaan koosta ja mallien erilaisuudesta. Mallin käytännön toimivuus tulee kuitenkin parhaiten selville silloin, kun se on laskentaihmisten käytössä. Ennustamiseen liittyy kuitenkin aina omat ongelmansa ja uudetkaan menetelmät eivät välttämättä poista näitä ongelmia.

Deinking flotation of recycled linerboard for food packaging applications

Brown packaging linerboard, made entirely from recovered pulp, was subjected to deinking flotation for evaluating the possible improvements in its chemical, optical and mechanical properties. The increase in the rate of recovered paper utilisation, along with the tendency towards lower basis weights, in the packaging paper production, has created a growing need for the utilisation of secondary fibers of improved quality. To attain better quality fibers, flotation deinking of brown grades is being considered, along with the addition of primary fibers to recovered paper furnish. Numerous conducted studies, in which the flotation technology was used in the treatment of brown grades, support this idea. Most of them show that the quality of fibers is improved after flotation deinking, resulting in higher mechanical properties of the deinked handsheets and in lower amounts of chemical contaminants. As to food and human health safety, packaging paper has to meet specific requirements, to be classified as suitable for its direct contact with foods. Recycled paper and board may contain many potential contaminants, which, especially in the case of direct food contact, may migrate from packaging materials into foodstuffs. In this work, the linerboard sample selected for deinking was made from recycled fibers not submitted previously to chemical deinking flotation. Therefore, the original sample contained many noncellulosic components, as well as the residues of printing inks. The studied linerboardsample was a type of packaging paper used for contact with food products that are usually peeled before use, e.g. fruits and vegetables. The decrease in the amount of chemical contaminants, after conducting deinking flotation, was evaluated, along with the changes in the mechanical and optical properties of the deinked handsheets. Food contact analysis was done on both the original paper samples and the filter pads and handsheets made before and after deinking flotation. Food contact analysis consisted of migration tests of brightening agents, colorants, PCPs, formaldehydes and metals. Microbiological tests were also performed to determine the possible transfer of antimicrobial constituents

Pre-dispersal predation effect on seed packaging strategies and seed viability.

An increased understanding of intraspecific seed packaging (i.e. seed size/number strategy) variation across different environments may improve current knowledge of the ecological forces that drive seed evolution in plants. In particular, pre-dispersal seed predation may influence seed packaging strategies, triggering a reduction of the resources allocated to undamaged seeds within the preyed fruits. Assessing plant reactions to pre-dispersal seed predation is crucial to a better understanding of predation effects, but the response of plants to arthropod attacks remains unexplored. We have assessed the effect of cone predation on the size and viability of undamaged seeds in populations of Juniperus thurifera with contrasting seed packaging strategies, namely, North African populations with single-large-seeded cones and South European populations with multi-small-seeded cones. Our results show that the incidence of predation was lower on the single-large-seeded African cones than on the multi-small-seeded European ones. Seeds from non-preyed cones were also larger and had a higher germination success than uneaten seeds from preyed cones, but only in populations with multi-seeded cones and in cones attacked by Trisetacus sp., suggesting a differential plastic response to predation. It is possible that pre-dispersal seed predation has been a strong selective pressure in European populations with high cone predation rates, being a process which maintains multi-small-seeded cones and empty seeds as a strategy to save some seeds from predation. Conversely, pre-dispersal predation might not have a strong effect in the African populations with single-large-seeded cones characterized by seed germination and filling rates higher than those in the European populations. Our results indicate that differences in pre-dispersal seed predators and predation levels may affect both selection on and intraspecific variation in seed packaging.

Use of new silica fillers as additives for polymers used in packaging of fruit

The objective of this work was to synthesize nanosilicas with different degree of hydrophobicity by the sol-gel method, using tetraethyl orthosilicate as a precursor. For this purpose, 3-aminopropyl triethoxysilane (APS) and 1,1,1,3,3,3 - hexamethyldisilazane (HMDS), were added during synthesis as modifiers. A commercial biopolymer (Hexamoll Dinch, BASF) intended for packaging of apples, was added to the new nanosilicas. The materials obtained were characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, potentiometric titration, porosity, specific surface area and hydrophobicity/hydrophilicity by wetting test. Colorimetry was used to evaluate change in apple pulp color after contact with the different silicas.

Creating carbon footprint calculating tool for plastic packaging products

The environmental challenges of plastic packaging industry have increased remarkably along with climate change debate. The interest to study carbon footprints of packaging has increased in packaging industry to find out the real climate change impacts of packaging. In this thesis the greenhouse gas discharges of plastic packaging during their life cycle is examined. The carbon footprint is calculated for food packaging manufactured from plastic laminate. The structure of the laminate is low density polyethylene (PE-LD) and oriented polypropylene (OPP), which have been joined together with laminating adhesive. The purpose is to find out the possibilities to create a carbon footprint calculating tool for plastic packaging and its usability in a plastic packaging manufacturing company. As a carbon footprint calculating method PAS 2050 standard has been used. In the calculations direct and indirect greenhouse gas discharges as well as avoided discharges are considered. Avoided discharges are born for example in packaging waste utilization as energy. The results of the calculations have been used to create a simple calculating tool to be used for similar laminate structures. Although the utilization of the calculating tool is limited to one manufacturing plant because the primary activity data is dependent of geographical location and for example the discharges of used energy in the plant. The results give an approximation of the climate change potential caused by the laminate. It is although noticed that calculations do not include all environmental impacts of plastic packaging´s life cycle.

Packaging concept development for an assortment of medical device products

Diplomityön tavoitteena oli kehittää Wipak Oy:n valmistamille sterilointipakkauksille tulevaisuuden pakkauskonsepti. Sterilointipakkaukset luokitellaan lääkelaitedirektiivin mukaan lisätarvikkeiksi luokan 1 lääkelaitteille, ja tämä näkökulma oli vahvasti mukana konseptin kehityksessä. Lähtökohtana pakkauskonseptin suunnittelulle oli tuotteiden arvoketjussa, eli pakata tuotteet siten että pakkausten avulla voidaan tuottaa lisäarvoa arvoketjun toimijoille. Tavoitteena oli parantaa pakkausten viestintää, toimivuutta/tehokkuutta toimitusketjussa sekä vahvistaa brändin imagoa myynti- ja kuljetuspakkauksen avulla. Lääkinnälliset laitteet ja tarvikkeet ovat lainsäädännön ja normien avulla tarkasti säädeltyjä. Näiden normien vaatimukset asettavat perusteet myynti- ja kuljetuspakkausten kehittämiselle. Tämän lisäksi suunnittelussa on huomioitu asiakkaiden toiveet ja kehitystarpeet. Kirjallisuusosuudessa on keskitytty lääkinnällisten laitteiden pakkausyksiköiden toimintoihin sekä niiden kehitysnäkymiin. Pääpaino on ollut pakkausmerkintöjen ja jäljitettävyyden kehittämisellä, koska tietojen automaattisen tunnistuksen hyödyntäminen lääkintälaitteiden pakkausten arvoketjussa on kasvava trendi. Manuaalisesti tehtävät tuotevirtojen kirjaukset ketjun eri toimijoiden osalta lisäävät riskejä jäljitettävyyden kannalta ja aiheuttavat lisätyötä ja – kustannuksia ketjun kaikille osapuolille. Ehdotus uudesta pakkauskonseptista on kehitetty näiden tietojen pohjalta. Ehdotuksessa on huomioitu lainsäädännöstä ja ketjun toimijoilta tulevat tarpeet, sekä alan tulevaisuuden kehitysnäkymät. Ehdotetun pakkauskonseptin avulla saadaan lisättyä myynti- ja kuljetuspakkausten tehokkuutta, parannettua jäljitettävyyttä ja helpotettu arvoketjun alavirran toimijoiden työtä lisäämällä erillinen sisäpakkaus myyntiyksikön sisälle. Työssä on lisäksi selvitetty pakkauskonseptin kustannusvaikutukset tuotteiden hintaan. Lopussa on ehdotettu jatkotoimenpiteet suunnitelman implementoimisesta käytäntöön.

Packaging inks for folding cartons used in food packaging

This thesis examined packaging inks suitable for folding cartons used in food packaging. The recent cases of compounds migrating from packaging inks into packed food, have forced the packaging ink manufacturers to develop inks that do not include substances at a level, that may pose a risk to the health of a consumer or to the quality of packed food. Food packaging is a sensitive area and subject to extensive legislation. This research presents the current situation on regulatory documents that can be used to demonstrate the safety of packaging inks used in food packaging. In the research, data was also collected on the available packaging inks for food packaging in packaging ink market. Test printing was performed with five printing inks and three varnishes on Ensocoat board, produced by Stora Enso. Tests results regarding print quality, runnability, sensory properties and migration were analysed. The packaging inks with the finest performance in the tests were ultra violet curing printing ink and varnish. The results showed that ultra violet curing printing technology in food contact applications is an important research area, with further research possibly being able to redeem the UV technologies' bad reputation within the packaging supply chain.

‘Sweet grape’ tomato post harvest packaging

ABSTRACT This paper aims at evaluating the shelf life of mini tomatoes (Lycopersicum esculentum Mill.) cultivar ‘Sweet Grape’, grown in hydroponics, and stored under environmental and refrigerated conditions inside different packages. We adopted a completely randomized design, in which treatments were combinations of storage conditions: environment (e) and refrigerated (r) with packaging: polyvinyl chloride film (PVC); low-density polyethylene (LDPE); biofilm of tomato fruit of Solanum lycocarpum A.St.-Hil (lobeira) (TFB); cassava starch biofilm (CSB); carnauba wax (Copernicia prunifera) (CW), and without packaging - control (C). Physicochemical and sensory tests were carried out at the beginning (day zero), and at 8, 19, and 33 days of storage (DS). Fruit stored inside PVCr, LDPEe, LDPEr, and CWr had an acceptable shelf life of 33 days. The use of cassava and tomato starches were not effective in controlling fruit fresh weight loss. ‘Sweet Grape’ tomato postharvest conservation was enhanced under refrigerated conditions. The sensory evaluation results revealed that CWr treatment most pleased appraisers, while PCV had the highest rejection rate.
