Labelling metallized paper

In addition to these applications in the food industry which are first and foremost a result of the improved barrier properties, there are other applications in the consumer sector in which the aesthetic value of products is enhanced by use of metallized films. A typical example is the use of metallized paper for drinks bottles. Numerous brands of bottled beer are promoted by use of metallized paper labels. This design of the bottle primarily serves the purpose of producing an eye-catching effect to capture consumers attention the bottles on the shelf are designed to stand out from other beers and give the impression of a superior and more precious product. This is also the reason for using metallic elements on brochures and promotional materials. 

The desired bottles then proceed to the grinder and the washing machine. The ground plastic is washed to remove product and labels. The paper labels sink and the HD PE is floated off the top and conveyed to a drier. Contaminants such as glass and metals also sink and are discarded with the paper labels. After the material is dry, it can be boxed or extruded and pelletized. Color or additives can be added to the resin prior to extrusion if necessary. 

Any of the metal containers discussed can be labelled instead of printed. Labelling is often used for small quantity and short runs, and is also advantageous when a packer requires several print variations on otherwise identical containers. In this instance the packer is usually able to operate on a smaller stock holding of empty containers and has greater flexibility to meet changing market requirements. Labels , include paper- or plastic-based materials, and stretch-shrink sleeving. 

PET scrap suitable for glycolytic recycle includes production waste, fibers, film, flake, and bottles. In a practical system, major contaminants are separated from feedstocks, e.g., bottle waste is cleaned and separated from a polyethylene base, paper labels, metallic caps, and liners. For many end uses, colored PET must also be segregated. (Highly modified copolymers, glass-reinforced resin, fiber, or fabric blends are not suitable for glycolysis. These can only be recovered by methanolysis/hydrolysis.) Since reaction time depends on surface area, PET feedstocks must be reduced to relatively small particles by grinding, cutting, etc. 

The bottles are inspected for fill-height and then are conveyed to the labeller (Fig. 20.29). Bottle labels are made of (/) sized machine-coated paper, ( ) wet-strength paper, Hi) foil, or (/v) metallized paper. The first is cheapest and the range of grades is 70-85 g/m. Wet-strength paper is paper treated with either melamine-formaldehyde or urea-formaldehyde resins. Compared with the machine-coated paper it is marginally more expensive and is less likely to be pulped in modern bottle washers. Aluminium foil is 4-5-fold more expensive... 

The battery jacket can be made of various components metal, paper, plastic, polymer films, plain or asphalt-lined cardboard, or foil in combination or alone. The jacket provides strength, protection, leakage prevention, electrical isolation, decoration, and a site for the manufacturer s label. In many manufacturers designs, the jacket is an integral part of the sealing system. It locks some seals in place, provides a vent path for the escape of gases, or acts as a supporting member to allow seals to flex under internal gas pressures. In the inside-out construction, the jacket was the container in which a carb on-wax collector was impact-molded (Fig. 8.4). 

Bromates represent a potential fire and explosion hazard if heated, subjected to shock, or acidified. They should not be allowed to contact reactive organic matter, including paper and wood. Industrial quantities are packed in fiber dmms with polyethylene liners or in metal dmms. Laboratory quantities are supphed in glass bottles. For shipment, a yellow oxidizer label is required under DOT regulations. 

Labels are mostly small versions of placards. Labels may be found not only on metal containers, but also those made of wood, plastic, carboard, and even paper bags. Since federeil labels require only one label on the outside of shipping containers, labels may not be visible due to the way they are loaded. Containers eire also sometimes intentionally mislabled to prevent identification of illegally shipped material. 

This is the one example in which metal is not the substrate. Corrosion takes on a new meaning the coating here is required to protect the substrate from direct attack by corrosive substances, from water to more powerful household or industrial chemicals, such as grease, alcohols and bleach. We are concerned with the industrial application of thin protective layers to paper (e.g. labels), card (e.g. playing cards) and many wooden articles, including industrially finished doors, window frames and, particularly, furniture. 

For a couple of years 0.25% Hg became the technical standard. It has to be pointed out that the mercury content of the metallic zinc has to be divided by a factor of roughly 10 to give the mercury content based on the total cell weight of an AA (LR-6) cell. These values are sometimes indicated on the cell labels. With decreasing amalgamation, other corrosion inhibitors had to take over the role of mercury. There are numerous papers and patents claiming corrosion-inhibiting activities of elements like A1, In, T1, Cd, Ga, Na, ... 

Label the ends of the filter paper with the metal strips to be tested (See Figure A). 

Offset lithography is the most common process used for printing on paper. It is used for folding carton stock and for can and bottle labels. Most lithographic presses are sheet fed, although there are some web-fed presses. A particular application of offset lithography is the printing of flat metal sheets that are then... 

Moisture-Based Adhesives. The thin film of moisture-diluted adhesive applied costs very little per 1000 labels, plus labor costs. Plain paper is most widely applied to glass, but can be applied to metal, particularly in the form of a complete wraparound label. Application can be by hand, semiautomatic, or fully automatic methods. Speeds of 1000 or more per min can be achieved. 

Pressure-sensitive labels can be applied to most materials (wood, plastic, metal, glass, paper, and board). As the adhesives are resin-based (plasticized thermoplastics), migration problems can occur when they are applied to certain plastics (e.g., PVC, LDPE).
