The goal of this report is to serve as input for the harmonized sector approach for labelling industry and is not suited to gain insight in product or material performance. Separately conducted LCA studies of products or services can never be compared, as there is no assurance that studies have been conducted similarly. Only LCAs which have been set-up as comparative LCAs can be used for performance comparison. This report is based on data from the case study participant and general information from literature and databases. Application of the information is strictly at the discretion and the responsibility of the reader. PRé Consultants, FINAT and TMLI are not liable for any loss or damage arising from the use of the information in this document. 1 Introduction The world-wide association for manufacturers of self-adhesive labels and related products and services (FINAT) and the premier association for the label and package printing industry (TLMI) want to provide their members with an LCA guidance document for the industry in order to ensure one harmonised approach for conducting LCA studies on self-adhesive label products. As part of this work two case studies have been conducted namely a LCA of a polypropylene self-adhesive label and a LCA of a Paper self-adhesive Label. The outcomes from the case studies have been used as input to develop this harmonized LCA approach for labelling products. This current report describes a case study LCA of a paper self-adhesive label. This LCA will provide a good insight into the appropriate scope and system boundaries to be considered, an identification of the relevant life cycle stages, processes and impact categories, and an awareness of the implications of choices and limitations. 2 Goal In close collaboration with the label material manufacturer and printer-converter, an LCA case study was performed on the production of a paper self-adhesive labels for a plastic bottle. The goal was to determine the environmental impact of a paper self-adhesive labels and to identify the environmental hotspots in the life cycle. Additionally, the insights of this case study are used for the development of a harmonized approach for the labeling sector. On basis of this study a one-pager showing with the most relevant insights has been created. This one-pager may be used for external communication. 3 Scope 3.1 Product The product under study is a self-adhesive paper label for a PET bottle. The label is made of a wood free face material, with a clear permanent acrylic adhesive on a paper uncoated liner. The label is die-cut and stripped at high speeds on standard web-fed presses with either flatbed or rotary dies. The labels are flexo-printed using UV printing inks and a direct or rotary relief printing process with elastic, raised print forms or plates which are attached to a plate cylinder. 3.2 Functional unit The functional unit describes qualitatively and quantitatively the function(s) or the service(s) provided by the product analysed. The functional unit is used to define what the LCA is measuring, and provides a reference to which the inputs and outputs can be related. In this case, the functional 1 PRé Consultants bv unit of the product under study was defined as 1m2 of ready-made label, applied at the brand owner. 3.3 System boundaries The scope of the study is cradle to grave. This means that all activities throughout the life cycle of each panel will be included in the assessment, that is: the production stage, use (i.e. application onto the bottle), and waste processing for recycling and disposal. A simplified flow chart of the life cycle is shown in Figure 1. Figure 1. A simplified flow chart of the life cycle of the printed label. 3.4 Cut-off criteria All processes were included in the LCA, so no cut-off criteria were used. The only distinction is that specific data is used for foreground processes and generic data is used for background processes. 3.5 Impact assessment method The Impact Assessment Method (IAM) is used is the ReCiPe1 Endpoint (H) method (H stands for a Hierarchist perspective, which is the default version). ReCiPe proposes a feasible implementation of a combined midpoint categories (expressed in units of a reference substance) and damage approach, linking all types of LCI results (elementary flows and other interventions) via midpoint categories to four damage categories: human health, ecosystem quality, climate change, and resources. Normalization can be performed either at midpoint or at damage level. Midpoints are used for a more specific and detailed analysis, whereas damage endpoints are useful to communicate the results

As a result, there is little awareness of the adhesive and sealant industry and the benefits it brings. The aim of FEICA’s 2020 Facts & Figures is to provide a concise overview of the European adhesive and sealant industry. This specialty chemical sector, which represents about 2% of the total European chemical industry’s turnover, contributes more than 17 billion euros to the EU economy and employs more than 45,000 people. Adhesives and sealants: a history of innovation The first use of bonding technology by humans can be dated to around 200,000 B.C., when birch-bark-tar was used to glue stone arrowheads to a shaft. Subsequently, humans used a range of natural materials – such as blood and animal protein, fish, resins from trees, natural rubber and milk protein – as bases for adhesives and sealants. Towards the end of the 19th Century, synthetic materials began to be used, spawning many more innovative adhesives and sealants. A dynamic and successful industry Today, the European adhesive and sealant industry is a success story that makes many everyday products possible, contributes to the economy, fosters sustainable development, encourages innovation and offers stimulating careers for people with a wide range of skills.

    molecules Article Micro-Fibrillated Cellulose in Adhesive Systems for the Production of Wood-Based Panels Emmanouil Karagiannidis *, Charles Markessini and Eleftheria Athanassiadou CHIMAR HELLAS S.A.,15 km National Road, Thessaloniki–Polygyros, 57001 Thessaloniki, Greece; [email protected] (C.M.); [email protected] (E.A.) * Correspondence: [email protected]; Tel.: +30-2310-424167 Academic Editors: Alejandro Rodríguez, Eduardo Espinosa and Fabrizio Sarasini Received: 31 July 2020; Accepted: 18 October 2020; Published: 21 October 2020 Abstract: Micro-Fibrillated Cellulose (MFC) is a new type of bio-based additive, coming from wood cellulose. It can compete and substitute oil derived chemicals in several application fields. In the present work, the use of micro-fibrillated cellulose, in waterborne adhesive systems applied in the manufacture of composite wood-based panels was evaluated. Research was conducted to test the potential of improving the performance of wood-based panel types such as particleboard, waferboard or randomly-oriented strand board and plywood, by the application of MFC and the substitution of conventional and non-renewable chemical compounds. The approaches followed to introduce MFC into the adhesive systems were three, i.e., MFC 2% suspension added during the adhesive resin synthesis, MFC 10% paste admixed with the already prepared adhesive resin and MFC 2% suspension admixed with the already prepared resin. It was found that MFC improves not only the performance of the final wood panel products but also the behaviour of the applied adhesive polymer colloids (e.g., rheology improvement), especially when admixed with the already prepared resins. Moreover, it was proven that when MFC is introduced into the adhesive resin system, there is a possibility of decreasing the resin consumption, by maintaining the board performance.

  • Choice of Structural Adhesives
    Choice of Structural Adhesives OPTI 521 Tutorial by Tianquan Su Abstract This tutorial focuses on introduction to polymer adhesives. Basic principles are introduced about choice of polymer structural adhesives used in opto‐mechanics. The fundamentals of adhesives are addressed. Main classes of polymer adhesives and their properties are described. Basic steps are provided to help make choice during designing. Introduction Various adhesives have found welcome places in optical instrument design and manufacture as replacements for screws, rivets, clamps, and other forms of fasteners. When used in structural bonding applications, they always function as integral components in the ensemble rather than as separate entities. Bonded structures are often lighter in weight, lower in cost, and easier to assemble than those made by mechanical methods. They also distribute stresses more uniform‐ ly than mechanical fasteners and are more or less flexible. This is a highly desirable feature in some applications involving high mechanical forces or when damping is needed. Among com‐ mon adhesive material classes, such as polymers, metals (solders), and inorganic glass powders (“frits”), polymers are the most widely used ones. The following discuss will focus within poly‐ mers. Adhesive fundamentals The basic function of adhesive is to join parts. They offer convenient or cost‐effective alterna‐ tives to conventional joining methods such as soldering, welding and bolting. Some materials need adhesively bonded joins for optimum or adequate performance, for example: joining of notch sensitive “brittle” materials that are intolerant of bolt holes (e.g., engineering composites, ceramics, and glasses). Some common adhesive material classes are: polymers, metals (solders), and Inorganic glass powders (“frits”, solder glasses).

  • Pressure Sensitive Adhesives
    TECHNICAL TIP PRESSURE SENSITIVE ADHESIVES The pressure sensitive adhesive (PSA) is the integral component of any pressure sensitive media or tape. It is often the unseen component of the product, since the middle layer of pressure sensitive media is sandwiched between the facestock and liner. Many pressure sensitive adhesives are clear and therefore not easily detected. On tape products, the adhesive is between the two layers of facestock in a roll and is often used without the applicator noting the existence of the adhesive. As long as the tape sticks during application, no one give the adhesive much notice because it is doing its job. If a pressure sensitive product fails it is usually the adhesive that gets the blame. Most of the time the pressure sensitive adhesive is not the primary reason for an adhesion failure but unfortunately the easiest component to assign blame. A pressure sensitive adhesive is a material that will hold two surfaces together solely by surface contact. This bond is accelerated by the application of external pressure to the adhesive. PSA’s are able to bond a wide variety of materials such as papers, plastics, metals, wood and glass. A PSA is a dry solid that does not require activation by water, solvent, or heat. Pressure sensitive adhesives are permanently tacky at room temperature. Pressure sensitive adhesives can be used as replacement to screws, rivets, nuts and bolts, clips, and any other form of attachment. Ease of application makes PSA’s worthy of consideration in many manufacturing processes and makes pressure sensitive media an excellent choice for point of purchase applications and general purpose graphics.
